 Diving in Chongqing and salvaging deep diving equipment in divers


As at 29 oclock, 23 hours, all deep diving equipment has arrived at the pier. Zhou Dongrong said that because of the dangerous gas and large equipment is not suitable for air transportation, these professional equipment in the road network traffic management department in collaboration with the shortest time from Shanghai to Wanzhou.

Zhou Dongrong said that the speed of the buss descent, the effect of the added water flow and the depth of the river make it difficult to find the specific location of the bus. After detecting the position of the bus through multi-beam scanning instruments and underwater robots, the depth of the water is about 73 meters (7.3 times the pressure of the standard atmospheric pressure). Usually more than 60 meters of water depth is the limit of air diving, need to use professional helium-oxygen diving technology, and diving before the actual depth of helium and oxygen required to configure divers to breathe with the ratio of helium to oxygen, slightly inadvertent divers will be life-threatening. In addition, because helium-oxygen diving operation time is very short, divers each operation time is about 35 minutes, and need 5 to 6 hours to decompression and decompression chamber decompression. At present, the salvage team has mobilized 18 divers with deep diving capability to arrive at the scene. At the same time, on-site medical, electrical and mechanical, emergency and other diving security groups have all been put in place. According to the preliminary survey, the underwater environment is complex, with rocks, steel structures, fishing nets and turbulent flow and other risk factors. Divers can see only 1-2 square meters underwater, diving operation is very difficult, and the overturn of the bus is unknown, the structure of the vehicle may be damaged, the specific situation to be further determined after divers dive survey. .

According to the preliminary survey, the underwater environment is complex, there are rocks, steel structures, fishing nets and turbulent flow and other risk factors, divers underwater visible range is only 1-2 square meters, diving operation is extremely difficult, and bus overturn situation is unknown, vehicle structure may be damaged, the specific situation to be further determined after divers dive survey.
