Deep foundation pit construction method for keeping underground water dynamically balanced
The invention discloses a deep foundation pit construction method for keeping underground water dynamically balanced. The deep foundation pit construction method comprises the following steps that a booster pump is provided, the inlet end of the booster pump is connected with a water pumping pipe, and the outlet end of the booster pump is connected with a recharge pipe; in the process of excavating earth and stone to form a foundation pit, a plurality of water collecting wells and a plurality of recharge wells are drilled and tapped in the adjacent region around the foundation pit, and the relative distance between the recharge wells and the foundation pit is larger than the relative distance between the water collecting wells and the foundation pit; and the water pumping pipe stretches into the water collecting wells, then the recharge pipe stretches into the recharge wells, and the underground water collected in the water collecting wells is recharged to the underground through the recharge wells till excavation construction of the foundation pit is finished. By the adoption of the technical scheme, the underground water gushing in the foundation pit excavation process is pumpedout in time, the pumped underground water is recharged to the region around the foundation pit in time, damage to the underground soil structure is reduced, the risk of sedimentation of the foundationpit and building facilities around the foundation pit is reduced, and the ecological environment is kept.
本发明公开了一种保持地下水动态衡平的深基坑施工方法，包括以下步骤：提供增压泵，增压泵入口端连接有抽水管，增压泵出口端连接有回灌管，在挖掘土石方形成基坑的过程中，同时在基坑周围邻近地域钻攻形成多个集水井和多个回灌井，回灌井与基坑之间的相对距离大于集水井与基坑之间的相对距离，将抽水管伸入集水井内，再将回灌管伸入回灌井以内，将集水井内收集到的地下水通过回灌井在回灌至地下，直至基坑挖掘施工结束。采用本发明的技术方案，既及时将挖掘基坑过程中涌出的地下水抽取出来，又及时将抽取出的地下水回灌至基坑周围领域地域，减少了对地下土体结构的破坏，降低了基坑及其周边建筑物设施出现沉降的风险，保持了生态坏境。
