 Shenzhen Death 11 Rainstorm Surviving Workers: Suddenly the Rising Water Runs Cant Win


During a rainstorm, 16 people working in underground canals and culverts were washed away. In the end, five survived and 11 died.

Afterwards, the Shenzhen Emergency Management Bureau described the storm as follows: short-term precipitation is extremely extreme, almost half of the precipitation is concentrated in a short period of 10 minutes, reaching 50 or 100 years once; the maximum half-hour rainfall is 73.4 mm, which is the largest half-hour rainfall since the Shenzhen Meteorological Records; experts from Guangdong Meteorological Station and Central Meteorological Station have identified the rainfall as the largest half-hour since April; It is the 4.11 Shenzhen Short-term Extreme Heavy Rainfall Weather Event.

In the face of the storm, the local meteorological department had already warned. At 20:10 on April 11, the Yellow rainstorm warning was issued, and the whole city of Shenzhen entered a rainstorm alert state. In an interview with Pengfeng News, the head of Shenzhen Meteorological Bureau said that the Yellow rainstorm warning signal issued by the meteorological department was accurate. Rainfall lasts for a short period of time, concentrated within half an hour, and when the rainfall reaches 50mm, it will end immediately. Because according to the condition of continuous rainfall, the orange rainstorm warning standard of the districts can not be reached.

According to official notifications, the time for floods caused by heavy rains to wash away workers was around 22:00 on November 11, which meant that about 2 hours had passed before the Yellow rainstorm warning came into effect.

Why does a rain cause so many deaths? Does the water department receive early warning and take preventive measures? On the afternoon of April 13, a report published by Xinhua News Agency sent out questioning.

At present, the relevant departments in Shenzhen have not published the results of the investigation and treatment of the accident.

Sudden rainstorm

Cloudy to shower, local thunderstorms; temperature 25-30 degrees C; south wind 2-3 grades; relative humidity 55-90%.

At 5:28 a.m., the Shenzhen Meteorological Bureau issued Todays Weather on April 11. Judging from the information released, the weather conditions on that day were not special and few people cared.

In the evening, things changed a little.

At 17:47 on the 11th, Shenzhen Meteorological Bureau officials micro-released Cold-warm confrontation! Is rain coming? Article 1. According to the article, after the Qingming Festival, a strong cold air swept the city and grabbed the land in the north, causing a great cooling in many places, and some places were beaten back to winter overnight. Nowadays, the fierce cold air has reached the coast of South China, but the coast of South China in this season is not the main field of cold air, and the warm and wet air flow in the south of the coast has been lingering here for many days. The cold-warm confrontation means that strong convective weather, such as thunderstorms, strong winds and hail, can easily be triggered.

In the next hour, Shenzhen Meteorological Bureau issued four warnings: 19:10, lightning warning; 19:55, hail zoning warning; 20:00, strong wind yellow warning; 20:10, rainstorm yellow warning. At the same time, strong convective weather forecast information and popular science propaganda of strong convective weather defense are released to the public through TV scrolling subtitles, two micro-terminals, network media and other channels.

The storm happened around 21 oclock that day.

According to the official website of Shenzhen Meteorological Bureau, the whole process of heavy rainfall across Shenzhen lasted more than two hours, but the same place lasted only about 30 minutes. Almost half of the rainfall is concentrated in just ten minutes.

From 19:00 to 23:00 on that day, Shenzhen experienced two strong convective weather processes. By 2315 hours, the Yellow rainstorm and the Yellow gale warning will be cancelled in Shenzhen. Shenzhen Meteorological Bureau summarized the characteristics of the weather process as follows: strong locality, short duration, strong rain, accompanied by short-term gale, thunder and hail.

Monitoring showed that hail appeared in Northwest Shenzhen around 19:00; short-term extreme heavy precipitation occurred around 21:00, when heavy precipitation occurred, wind, rain, thunder and lightning overlapped, accompanied by 8-9 level short-term gale, 704 thunder and lightning, local hail appeared in Guangming Baoan.

Heavy rains and floods are not unfamiliar to Shenzhen.

Shenzhen is a subtropical oceanic monsoon climate. The average annual rainfall in Shenzhen is 1935.8 mm. The rainfall mainly concentrates in April-September, accounting for 85% of the annual rainfall. Meanwhile, typhoons and rainstorms are frequent in Shenzhen, with an average of 3.5 times a year affected by typhoons.

According to the official website of Shenzhen Water Bureau, due to the urbanization process destroying the natural water system to a certain extent, and the low standard of the existing flood control and drainage infrastructure construction, the drainage facilities in some areas of Shenzhen are not perfect enough and are threatened by floods and waterlogging disasters.

This year, the flood season in Shenzhen is one month earlier than in previous years.

According to public reports, Shenzhen met the meteorological flood standard after a rain on March 5. According to the Shenzhen Emergency Management Bureau, the flood season is one month earlier than previous years, and the rainfall in Beijiang and Dongjiang valleys is three times as much as that in the same period. It is expected that the total rainfall in the whole year will be more; typhoon landing will be stronger, and the flood control situation will be severe and not optimistic.

At 22:57 on April 11, the Shenzhen Meteorological Bureau officer micro-released information and shouted to netizens: You are all people who have just passed the mangosteen. Is it a big scene tonight?

One netizen joked and answered, After staying in Shenzhen for so many years, isnt it a drizzle? Another netizen said with a lingering fear, I really thought of mangosteen in that particularly big time.

Last September, strong typhoon Mangosteen landed in Guangdong Province. The General Command of Flood and Drought Control and Wind Prevention of Guangdong Province launched the emergency response of level I of Wind Protection. The city of Shenzhen four stops: shutdown, shutdown, shutdown, shutdown of classes.

During the typhoon exam, 74 stations in Shenzhen recorded gusts above grade 12, with an average rainfall of 187.2 mm. At one time, 134004 users failed to restore power supply, and no one died as a result of the disaster.

Underground danger

On the evening of April 11, heavy rains hit Shenzhen, causing many dangerous situations.

Publicly reported that at 21:57 p.m., two employees of the water company were trapped in the sewer at exit A of Meilin Metro Station in Meilin Street, Futian District. Fortunately, they were rescued by firefighters. Firefighters learned that two workers of the water company were trapped in the sewer due to the sudden rainstorm when the sewer was about 4.5 meters deep and about 1 meter deep.

At 22:10 that evening, the police received a report that four workers were buried in a landslide near the West Lake Hotel, Baoan South Road, Luohu District. After that, four people were rescued safely.

The other three underground dangers are of great concern to the outside world.

According to previous official reports, at about 21:00 p.m. that night, Qiaoxiang Road area in Futian District encountered instantaneous heavy rainfall, and a short-term outbreak of floods washed into the Fengtang River Underground Channel. One of the five workers working on the Xiangmihu section of Fengtang River successfully reached the ground and four were washed away by the sudden flood when they retreated to the ground.

At about 21:40 on the same day, Guiyuan and Huangbei areas in Luohu District of Shenzhen suffered instantaneous heavy rainfall, and the short-term outbreak of floods washed into the underground canal under operation. At 22:10 and 22:55, we received warnings from two dredging workers in Luohu District that they could not escape being washed away by rainwater. Seven people were washed away at the construction site of the West Lake Hotel Section. Four people were rescued, one died and two lost contact. Five people were washed away at the construction site of the East Lake Park Section, and one was confirmed dead and four lost contact.

Sixteen people were washed away in three dangerous situations. By the afternoon of April 13, the last body was found and 11 people were killed.

Peng Mei News noted that in the early morning of April 13, Shenzhen Emergency Management Bureau adjusted the relevant statements: the Bijiashan River Underground Channel of Baoan South Road, Guiyuan Street, Luohu District, dredged the drainage ditch of Xihu Hotel Section. Seven of the 25 workers were prepared to evacuate when sudden floods washed away; the underground canal of Xiangmihu Street, Xiangmi Park, Futian District, dredged the silt. In the operation project, more than 10 workers were evacuated after receiving the warning notice, and 4 workers were washed away by the flood. Five workers were surveyed and surveyed in the underground culvert of Patriotic Road and Greenbelt along the river in Huangbei Street, Luohu District, when they were preparing to evacuate, they were washed away by the flood.

According to the latest report, in the three accidents mentioned above, at about 9 oclock that night, the relevant personnel were still working. Two of them were workers entering the underground canal to clear silt, and one was workers entering the underground culvert to survey and survey the work of silt removal, and some of them were washed away by the flood when they were preparing to evacuate.

Open data show that the underground canals are relatively open canals visible on the surface. The underground canals are hidden underground, and there is no water on the ground. Implicit culvert is a term of highway engineering. The filling depth of culvert top is more than 50 cm. There are circular culvert, stone arch culvert, box culvert and so on. Generally speaking, underground ditches and culverts are underground drainage ditches in cities.

De-silting and sewage interception of underground canals and culverts can sometimes be dangerous due to the complex internal environment.

The construction units of silt removal and sewage interception works of Fengtang River and other five river culverts in Futian District are the second-class sub-enterprise of the Eighth Hydropower Bureau, China Hydropower Eighth Bureau Limited Railway Company. According to an article published on the companys official website, the implication of the project has been silted up for more than 20 years, not only has it lost its flood-carrying function, like a purulentcecumin the human body, which constantly threatens the safety of the water quality of the Shenzhen River... It is the most difficult and riskiest project to clean up and intercept sewage in the Wuhe subterranean culvert section. It faces four challenges: poisonous gas, complex environment, unknown information and sewage sludge treatment.

The article said that from March 1 to 15 this year, there were three successive inrushes of water in the culvert. Within 10 minutes, the water level in the culvert rose rapidly from 20 centimeters to 2 meters deep. No accident of safety responsibility happened because of proper prevention and timely handling.

There are implications in the greening between Patriotic Road and Riverside Road in Luohu District. A nearby construction site worker said that he had seen workers go down to clear silt before; the next day, fire fighters and other personnel came to search and rescue.

Overtime construction

After the incident, Peng Mei News visited the three sites mentioned above.

On the afternoon of April 12, near the West Lake Hotel in Luohu District, the site of the accident was enclosed. According to the visual observation, there are 3-4 meters wide in the underground canal, and the sound of water can be heard. Many residents nearby said that recently, the site often worked overtime, inconveniencing residents.

The letter of apology posted on nearby buildings shows that on March 30 this year, Shenzhen Construction (Group) Co., Ltd. apologized to local residents for the noise caused by night construction in the parking lot of Xihu Hotel.

As the flood season has arrived, the water level in the culvert is deep and can not work normally, recently our department reduced the water level in the culvert by manual diversion and pumping, in order to rush to complete the joint construction period before the rains and tides, which led to continuous construction...The apology letter said that after receiving the relevant complaints, the local community also interviewed the construction party, and will adjust the construction process and time: The stopping time of the mechanical equipment outside the parking lot is 22:30, not more than 23:00 at the latest; after 23:00 in the culvert, no noise-producing work will be carried out.

In the middle green belt between Patriotic Road and Riverside Road in Luohu District, the surging news found that the green belt has several openings about 1 meter in diameter, which go down about 3 meters and reach the underground culvert. On April 13, from the entrance of the cave, we can still see that the current in the culvert is very fast.

Workers at a nearby highway construction site said that in peacetime, workers were seen entering the culvert operation, pulling out dirt, and then pulling it away. The next day, firefighters and others came here to search and rescue.

On the north side of Xiangmihu Park, no underground canal was found directly in the news of Peng Mei. A nearby resident said that the underground canal is just below the roadside. Workers are often seen to go down and dig up the mud, pick it up bit by bit, and then pull it away. Especially when the drainage of the nearby roads is not smooth, when there is water, the workers will come to dig it out.

Pengmei News query found that in the vicinity of the three incident sites, there are related projects such as silt removal and Sewage Interception under construction. The background is that Shenzhen has been vigorously improving water quality in recent years.

According to the official website of Shenzhen Water Administration, the river pollution in Shenzhen is relatively serious. Most rivers in Shenzhen are short and small, showing obvious characteristics of rain-source rivers. In rainy season, rivers are formed in dry season. There is no dynamic supplementary water source. The water environmental capacity is small. The urban pollution load far exceeds the local water environmental carrying capacity. The rivers in the urban area of the river basin are generally polluted, and the pressure of water environmental control is high. Great power.

In May last year, when the Ministry of Ecological Environment and the Ministry of Housing and Construction carried out special supervision on the environmental protection of black and odorous water in Shenzhen, 42 water bodies, such as Maozhou River and Futian River, were identified as eliminating or basically eliminating black and odorous water. Among the 159 black and odorous water bodies in Shenzhen, 117 of them are progressing smoothly, except 42 of which have been renovated.

On February 18, this year, the latest Work Program for the Decisive Year of Water Pollution Control in Shenzhen put forward that by the end of 2019, Shenzhen should eliminate all black and odorous water bodies, and the main first-level tributaries and all reservoir tributaries of the five major basins should eliminate inferior V types.

According to Shenzhen media reports, 2019 is the decisive year for water pollution control in Shenzhen. The city plans to complete nearly 50 billion yuan of investment in water pollution control. By 2020, the city will have completed nearly 120 billion yuan of investment in water pollution control, making up for the historical debt of water pollution control facilities construction.

According to a practitioner of Guangdong Water System, the burden of water control is heavy and the pressure is high everywhere. It is unavoidable that the construction is still under way around 9 p.m., which is more common.

Thrilling escape

Hu Bo (a pseudonym) is a silt cleaner at the Construction Office of West Lake Hotel Section in Luohu District. He said that the construction site had been completed, and on the evening of April 11, he went down to adjust the equipment. Suddenly the water rose, and no one could win in running.

In the sudden flood, Hu Bo and Zhang Xiaodong (alias) and another worker ran to the exit, and a forklift blocked the road. The current was too fast for them to go out for a while.

The surviving worker, Zhang Xiaodong (a pseudonym), is still hospitalized due to multiple injuries and drowning. Press reporter Chen Xuhou from Pengchao

Hu Po called his boss and asked the other party to call the firefighters. Afterwards, Hubo held his cell phone in his mouth and set himself on the steel bar of the well cover in the position of climbing a ladder. Finally, he waited for the firefighters.

Of the three, Zhang Xiaodong was the last to be rescued.

He is still hospitalized due to multiple injuries and drowning. In the hospital bed, he was sleepy, depressed and often silent. At 11:00 on April 13, when the doctor inquired, it took him a long time to whisper that he still had a headache and tightness in his chest.

The medical records show that the patient (referring to Zhang Xiaodong) fell into the sewer and soaked in water about three hours ago due to heavy rain at the construction site.

On the other hand, Dong Jian, a friend of Hu Bo and Zhang Xiaodong, also experienced danger.

I also turned on the digger. I dont think the water is big enough. Dong Jian said that when the water began to rise, he made a wrong prediction, but he quickly responded that he should go up.

Initially, this self-help method was not recognized by the workers. That fellow wants to go down. He says the water is rising. He wants to go down. Theres a rope there. Dong Jian thought that the idea of the workers was wrong, so he went up, and the workers followed him.

Dong Jian said that they had reached a high point where he and his colleagues cut the gap between the nearby drainage outlet and the wall, and the water level fell quickly, and they were able to escape.

On the second day of the incident, Van der Fan, the executive vice governor of Luohu District, introduced the situation to the media. At that time, the workers were carrying out water treatment and quality improvement works, and dredging the rain and sewage diversion. However, due to the heavy rain, some workers did not have time to evacuate. In Xihu Hotel Section, the space is a narrow underground channel and river in the underground pipeline. The water level rises from 1 meter to 4 meters in a short time, and the workers are washed away instantly.

Xinhua News Agency Questions and Early Warning

At 20:10 on April 11, Shenzhen Meteorological Bureau issued a yellow rainstorm warning. At about 21 oclock that evening, there were heavy rains in Shenzhen. According to official reports, three workers were washed away by the floods around 22:00.

Rainstorm yellow warning signal, its defense guidelines require: the city into a state of rainstorm alert, the public pay attention to listening to, watching, inquiring about the latest trends of rainstorm; outdoor operators to do a good job of rainproof measures, or to take shelter in safe places.

A staff member of Guangdong Water System who did not want to be named also said that the meteorological department issued a yellow warning signal. According to the relevant regulations, the water departments silt removal and sewage interception projects need to be stopped, and personnel need to be evacuated.

Pengmei News Interview learned that China Power Construction Water Environment Management Technology Co., Ltd. participated in the Maozhou River regulation project in Shenzhen. The company withdrew ahead of schedule after receiving a major weather report from Guangdong Emergency Management Department on April 11.

Near Patriotic Road and Riverside Road in Luohu District, there is a highway construction site. A worker inside told the surging news that on April 11, when they learned of the rainstorm, they stopped work. The rainstorm was really heavy that night. Although it only lasted for ten minutes, the roads beside them were 50-60 cm deep. If not evacuated in advance, they were still working in low-lying areas, which was very dangerous.

Why are there workers working under the rainstorm warning? Are early warning messages delivered to all work sites in time? On the afternoon of April 13, the Xinhua News Agency issued a report asking questions.

According to the Shenzhen Flood Prevention Preparedness Plan for 2018, the areas with high risk of flood and waterlogging disasters such as rivers are the areas with high risk of dangerous disasters around the construction projects, dangerous reservoirs and dangerous slopes. In addition, according to the Shenzhen Production Safety Accident Emergency Plan, the water bureau is responsible for organizing and guiding the construction of water projects and the safety production emergency management work of water source management units.

According to reports published by Xinhua News Agency, the reporter asked the relevant person in charge of Shenzhen Water Bureau whether the relevant emergency plan was launched to ensure safety in production when the flood occurred. Up to the time of press release, no response was received from Shenzhen Water Bureau.

Peng Mei News noted that at a press conference on the morning of April 12, Yin Xuekang, deputy director of Futian District Water Bureau, said that at 7:12 on April 11, after receiving the weather warning, they timely forwarded the weather forecast to the working group; at 8:30, they also forwarded the Yellow rainstorm information of the Meteorological Bureau; at 9:28, they asked the organizers of the construction units. Members of the construction cofferdam to carry out relevant treatment to ensure smooth road. However, due to the lucky mentality and carelessness of the construction units, the rainfall intensity has not been fully estimated, which is far more than expected.

Yin Xuekang said that all the water projects under construction had been asked to stop work in an all-round way, especially those involving box culvert construction and hidden culvert construction. After the investigation and confirmation of the accident conclusion is clear, the relevant departments will deal with the relevant responsible units severely and give top-notch treatment.

On the evening of April 11, in one hour, Shenzhen Meteorological Bureau issued four warning signals in succession, of which 20:10 issued a yellow rainstorm warning.

Involved enterprises

Pengmei News learned from the official channels that the construction units involved in Fengtang River accident in Futian District were China Construction Enterprise, China Water Conservancy and Hydropower Eighth Engineering Bureau Co., Ltd. and did not respond positively when contacting the other side to verify the relevant situation.

The bidding information inquired by the network shows that East China Survey and Design Research Institute Limited is a construction agent for many projects. On April 13, a staff member of the company told Peng Mei News that the company was a construction agent, not a construction party. On the same day, the head of the companys South China Regional Headquarters said that for the incident, the company was a construction agent. After the incident, the company actively cooperated with the relevant departments to investigate and deal with, and the aftermath work is also in progress. The relevant information is based on the official statement.

According to the relevant bidding information and the aforementioned apology letter, Shenzhen Construction (Group) Co., Ltd. is suspected to be the Construction Party of Luohu West Lake Hotel Section and Donghu Park Section. No one answered the inquired public telephone call from the surging news. On Saturday, April 13, Pengbao News went to Shenzhen Construction (Group) Co., Ltd., located at 8000 Shennan Avenue. No one was at work. Peng Mei news has not been able to contact the other side to verify the relevant situation.

At present, the relevant departments in Shenzhen have not published the names of 11 victims, which enterprises they belong to and the contracting and subcontracting of related projects.

Pengcheng News noted that the sudden disaster has triggered the Shenzhen Catastrophe Insurance Compensation Shortage, Shenzhen Catastrophe Insurance will be compensated. According to the Shenzhen catastrophe insurance clause, the compensation limit will be 250,000 yuan per person and 20,000 yuan per person for relatives.

On the second day of the incident, the Office of the Guangdong Safety Production Committee and the Guangdong Emergency Management Department issued the Emergency Notice on Further Strengthening the Safety Prevention in Flood Season. In terms of rationally arranging operations to ensure the safety of underground operations such as urban underground canals, housing, urban and rural construction, transportation, water conservancy and other departments at all levels and relevant engineering construction units should draw on the depth of the evening of April 11.
