Seepage channel device and method for deep subway station maintenance structure

Abstract

The invention discloses a deep-layer underground railway station maintenance structure seepage channel device and method and overcomes the defect that in the prior art, groundwater seepage is intercepted due to construction of an underground railway station. A soluble curtain device is arranged, and influences of construction on a water stop certain on flowing of underground water are reduced. According to a specific scheme, the deep-layer underground railway station maintenance structure seepage channel device comprises low-melting-point current-conducting plates and a liquid storage box for storing liquid generated after the low-melting-point current-conducting plates are melted; the low-melting-point current-conducting plates are fixed to steel reinforcement cages of ground connected walls and downwards placed into hole grooves of the ground connected walls along with the steel reinforcement cages of the ground connected walls, the low-melting-point current-conducting plates are provided with wires, and the wires are connected with a power source; and the liquid storage box is arranged at the bottom of one side of each low-melting-point current-conducting plate, and after an underground station structure is completed, the power source melts the low-melting-point current-conducting plates through the wires so that underground water seepage channels can be recovered.

Description

technical field [0001] The invention relates to the field of construction, in particular to the construction of a maintenance structure of a subway station, in particular to a seepage channel device and method for a maintenance structure of a deep subway station. Background technique [0002] With the rise of urbanization, more and more cities have begun to carry out subway construction. The subway station is buried deep in the ground, and the foundation pit needs to be excavated before pouring, and there is a lot of groundwater before the foundation pit is opened, so in order to ensure the safety of the foundation pit excavation, it is often necessary to build a ground connection wall as a water-stop curtain . A subway line is often equipped with multiple subway stations, and correspondingly, multiple ground connecting walls need to be built. The setting of the ground connection wall is very important to ensure the safety during the construction of the foundation pit. How...

Problems solved by technology

The setting of the ground connection wall is very important to ensure the safety during the construction of the foundation pit. However, because the depth of the ground connection wall is often very deep, once it is installed, it will also have a permanent impact on the regional groundwater flow, cutting off the original groundwater flow. The flow route pollutes the groundwater, and the groundwater washes the ground connection wall for a long time, which will easily affect the service life of the ground connection wall and the subway station
