Water replenishing and sedimentation preventing method for stratum around underground station
The invention provides a water replenishing and sedimentation preventing method for a stratum around an underground station. The method comprises the following steps that (1) a temporary water collecting station is arranged in the underground station, and the temporary water collecting station comprises a movable water sump and a water suction pump; (2) a water delivery pipeline is connected to the water suction pump, and the water delivery pipeline is communicated into the stratum; (3) a pressure regulating valve and a water pressure gauge are mounted on the water delivery pipeline; (4) a water inlet of the water suction pump is placed in the movable water sump, and meanwhile, the water suction pump is started; (5) the pressure regulating valve is adjusted by observing the water level of the stratum and the numerical value on the water pressure gauge, so that the water delivery of the water suction pump and the seepage water loss of the stratum are dynamically balanced. According to the water delivery scheme combining the water suction pump, the water delivery pipeline, the pressure regulating valve and the water pressure gauge, water is efficiently delivered into the upper stratum in time, and the problem of uniform sedimentation of the stratum around the underground station of the water-rich stratum and buildings on the stratum can be effectively solved.
本发明提供了一种地下车站周边地层补水防沉降方法，包括如下步骤：(1)在地下车站内设置临时集水站；临时集水站包括移动式水仓与抽水泵；(2)在抽水泵上连接输水管道，并将输水管道通入地层中；(3)在输水管道上安装调压阀与水压表；(4)将抽水泵的进水口置入移动式水仓中，同时，开启抽水泵；(5)通过观察地层的水位以及水压表上的数值来调节调压阀，使抽水泵的输水与地层的渗透失水之间动态平衡。本发明通过设置抽水泵、输水管道、调压阀以及水压表相结合的输水方案，将水及时高效的输送到上部地层中，可有效解决富水地层地下车站周边地层以及其上的建筑物均匀沉降问题。
