According to the Voice of China News Story at 7:08, on the morning of August 1, a large area of ​​landslide collapsed on the day before yesterday at Bao'an Central Station on the Metro Line 5 of Shenzhen Venture Road. In the soil.
The collapse occurred at the site of the Bao'an Center Station of the Metro. After a large area collapsed, two construction companies disputed whether the site belonged to the Metro Line 1 or the Line 5.

In the landslide, two work sheds were damaged and a small car fell into the pit. According to a reporter from the construction direction, the landslide did not cause casualties.
The reporter interviewed relevant experts. According to a preliminary analysis by engineering experts, the collapse of the pit was a complex geological condition of the foundation pit and the continuous rainfall in Shenzhen in recent days. The foundation pit is located in a thick layer of mud field soil and muddy mud layer. Due to continuous heavy rain in Shenzhen in recent months, the water content of the outer body of the foundation pit is saturated, during the process of earth excavation in the foundation pit, the foundation pit The water at the bottom was softened, and sudden deformation occurred in the foundation pit, which caused a large lateral displacement of the underground contact wall in the local area and caused landslides.
According to the follow-up investigation of the accident, according to the reporter's new information, in order to ensure the smooth construction of the follow-up construction and the absence of secondary disasters, the Metro Group has instructed the construction unit China Railway 15 Bureau Group to take the following measures: First, strengthen the site To supervise and arrange the engineering and technical personnel to check the safety hazards repeatedly on the construction site; secondly, the design institute shall formulate the follow-up detailed construction plan, and then strictly follow the plan after the experts' argumentation; and third, strengthen the monitoring of the construction. Actively cooperate with third-party monitoring to do a good job in monitoring the surrounding environment to ensure that secondary disasters do not occur.
