In the morning of the same day, with the last round of gunfire and the cheers of the workers on site, the cave super static laboratory, a supporting project of the national major scientific research project tianqin plan, realized the smooth tunnel opening in advance. Next, the interior decoration and entrance of scientific research equipment will be carried out successively, which is expected to be delivered to Zhongshan University in January 2021.

Tianqin plan cave super static laboratory is located in Zhuhai Campus of Sun Yat sen University. The main project includes the main body of the tunnel and the connecting line road. The main body of the tunnel is 1108 meters long, with a total area of about 24030 square meters. Peng Yonghui, project director of the cave super static laboratory of China Railway Tunnel Bureau, said, the tunnel is a medium shape, which is different from the previous tunnel engineering, and it is a crisscross tunnel group. There are 10 intersections, and there are many types of sections, so the excavation of the whole project is very difficult. . By introducing the advanced equipment of three arm rock drilling jumbo, the construction company has realized the efficient tunneling of the tunnel and completed the tunnel connection in advance.

The cave super static laboratory is one of the important ground-based construction facilities of tianqin plan, which will become the high-precision technical instrument and equipment detection platform of tianqin plan. Peng Yonghui, project director of the cave super static laboratory of China Railway Tunnel Bureau, said, the research of gravitational wave in this cave is less disturbed by the external environment, and the data obtained is more accurate and more conducive to scientific research..
