If the shield machine can not break through the hard rock in the subway construction, the hydraulic power station can be connected with the diamond chain saw and the crushing equipment, cutting and crushing the separated rock, reinforced concrete and other "blocking tiger", the damage thickness can reach 30 cm. .
The construction of the subway is difficult, the cycle is long, and the safety risks are high. In order to quickly and steadily respond to the “roadblocking” encountered by the Xiamen Metro during the construction process, and improve the subway project danger and emergency response capability, Xiamen established the first district emergency rescue team. It is equipped with 25 full-time rescuers.
This morning, the emergency rescue team was officially unveiled. The establishment of the first district rescue team marked the successful completion of the “1+4” layout of the emergency rescue of the rail transit project. The Xiamen Metro has 5 rescue teams. The "1+4" emergency rescue mechanism is to build an emergency rescue center (orbital group) + four district emergency rescue teams (China Jiaojian, China Railway Construction, China Railway, China Construction) to protect the Xiamen subway construction. At the base of the emergency rescue team at Haitang, the reporter saw the rescued mechanical equipment arranged in series, including the dual-circuit hydraulic power station supporting the operation of pumps, lighting and other mechanical equipment, car cranes, command vehicles, wheel excavators, and Vehicle lifting trucks, as well as basic materials, flood control, electricity, hardware tools, protective equipment and other five rescue materials.
According to the person in charge, during the construction of the subway, it is the most common danger that the site will be flooded due to the flood season. The Xiamen Emergency Rescue Team is equipped with a dual-circuit hydraulic power station. This equipment does not need to be connected to the power supply. It uses gasoline to drive the hydraulic drive. The pump can be quickly pumped in a few seconds. 200 tons of water can be pumped in one hour. The displacement is Generally 3 times the pump.
In addition, during the construction process, it is often encountered that the shield machine can not break through the hard rock when it is running. The hydraulic power station can quickly connect the diamond chain saw and the crushing equipment to quickly cut and crush the separated rock and reinforced concrete. . The equipment has been put into emergency rescue during the construction of Xinglin Qiaotou, Gaoqi Station and Haishu Avenue Station to ensure the smooth progress of the project.
