According to the report of Shenzhen Public Security Fire Brigade, at around 0: 00 on May 1 1, the construction site of the extension line of Metro Line 3 opposite Shenfubao Building in Shenzhen Futian Free Trade Zone collapsed partially. It is understood that the ground collapsed when a dump truck was working above the subway, saying that three workers were trapped. At present, the Shenzhen fire department is organizing rescue on the spot and dispatching reinforcements to the scene.

Immediately after the accident, Shenzhen started the emergency plan for construction projects in Shenzhen, and set up a rescue emergency headquarters led by the Municipal Housing and Construction Bureau, with the participation of the Municipal Safety Supervision Bureau, the Municipal Government Information Office, the Municipal Emergency Office, the Futian District Government, the Public Security Fire Bureau, the Metro Group and other departments. The headquarters consists of six groups, including comprehensive coordination group, emergency expert group, emergency rescue and disaster relief group, news propaganda group, logistics support group and aftermath treatment group, to carry out related work quickly.

City Housing and Construction Bureau sent five geotechnical experts to determine the rescue plan, and mobilized long-arm excavators, medium-sized excavators, small excavators, hydraulic grab machine, truck cranes, gantry cranes and other mechanical equipment to participate in the rescue.

As of 20: 02, two bodies have been dug up, and a third person has been found and is being dug up.

2. The cause of the incident

According to experts' preliminary judgment, the cause of the accident is that due to the recent heavy rainfall, the upper fill of the foundation pit is soaked and softened by water, and the lower silt is unstable, which leads to the instability and sliding of the excavation surface of the foundation pit. The specific reasons are under in-depth investigation.

It is reported that the construction unit of the project is Shenzhen Municipal Engineering Corporation, the supervision unit is Gansu Tieke Construction Engineering Consulting Co., Ltd., and the construction unit is Shenzhen Metro Group Co., Ltd.
