Foundation pit gushing water drainage and recharging construction method
The invention discloses a foundation pit gushing water drainage and recharging construction method. The method includes the steps that a recharge well and a sedimentation tank are excavated firstly, the depth of the recharge well and the depth of the sedimentation tank are both larger than the preset depth of a foundation pit, and a cobblestone layer is laid at the bottom of the sedimentation tank; a booster pump and a drainage pump are arranged, the inlet end of the booster pump extends into the sedimentation tank through a water taking pipe, and the outlet end of the booster pump extends into the recharge well through a recharge pipe; and the inlet end of the drainage pump extends into the foundation pit through a water pumping pipe, the outlet end of the drainage pump extends into the sedimentation tank through a drainage pipe, in the foundation pit excavating process, underground water flowing into the foundation pit is conveyed into the sedimentation tank through the drainage pumpto be settled, and then water is recharged into the underground through the booster pump. By adopting the technical scheme of the foundation pit gushing water drainage and recharging construction method, damage to an underground soil body structure and an underground water body is reduced, ecological environment protection is facilitated, a constructed area is still endowed with abundant underground water, the risk of sedimentation of the foundation pit and surrounding building facilities is reduced, and the method is economical, environmentally friendly and high in safety.
本发明公开了一种基坑涌水引流回灌施工方法，包括以下步骤：先挖掘回灌井和沉淀池，回灌井、沉淀池的深度均大于基坑预定深度，在沉淀池底部铺设鹅卵石层；设置增压泵和排水泵，增压泵入口端通过取水管伸入沉淀池内，增压泵出口端通过回灌管伸入回灌井内；排水泵入口端通过抽水管伸入基坑内，排水泵出口端通过排水管伸入沉淀池内，在挖掘基坑过程中，通过排水泵将涌入基坑内的地下水输送至沉淀池内沉淀，再通过增压泵将水回灌至地下。采用本发明的技术方案，减少了对地下土体结构和地下水体的破坏，有利于保护生态环境，使经过施工后的区域仍然存赋有充沛的地下水，降低了基坑及其周边建筑物设施出现沉降的风险，经济环保，安全性高。
