Foundation pit dewatering structure for overcrossing subway tunnel in complex environment
The invention provides a foundation pit dewatering structure for an over-crossing subway tunnel in a complex environment. The foundation pit dewatering structure comprises a dewatering well, a waterproof curtain, a double-row pile support and a recharge well. Wherein the dewatering well is arranged in a subway operation track range of a subway tunnel foundation pit; the recharge well is arranged around the periphery of the subway tunnel foundation pit; the double-row pile support is arranged on the side, close to an existing railway line, of the subway tunnel foundation pit. The waterproof curtain is arranged on the outer side of the subway tunnel foundation pit and forms a closed ring. According to the foundation pit dewatering structure used for the overpass subway tunnel in the complex environment, the double-row pile supporting and waterproof curtain structure is adopted, water pressure of an existing railway line and a subway tunnel foundation pit can be effectively isolated, leakage, deformation and damage of a foundation pit slope and a subway tunnel are prevented, and the foundation pit dewatering structure is high in practicability. And meanwhile, the stability and safety of foundation pit supporting are improved.
本申请提供了一种用于复杂环境下上跨地铁隧道的基坑降水结构，包括降水井、止水帷幕、双排桩支护、回灌井。其中，降水井设置于地铁隧道基坑地铁运行轨道范围内；回灌井环绕设置于地铁隧道基坑的外围；双排桩支护设置于地铁隧道基坑靠近既有铁路线的一侧；止水帷幕设置于地铁隧道基坑外侧，止水帷幕形成封闭环形。本申请提供的用于复杂环境下上跨地铁隧道的基坑降水结构，采用了双排桩支护和止水帷幕的结构，能够有效地隔离既有铁路线和地铁隧道基坑的水压力，防止基坑边坡和地铁隧道的渗漏、变形和破坏，同时提高基坑支护的稳定性和安全性。
