Background

The deep foundation pit engineering often adopts precipitation measures to eliminate the influence of underground water on construction, and in order to protect underground water resources and ensure the safety of buildings, pipelines and roads around the foundation pit, recharging measures are adopted. When the water inflow, the pumping drainage water yield and the reinjection water yield of the foundation pit basically reach a balanced state, the underground water can be kept at a basically stable position. Generally, precipitation tends to cause settlement of the surrounding ground surface, and recharge tends to cause uplift of the ground surface, both of which affect the safety of surrounding structures, underground pipelines, and roads. Therefore, precipitation recharge usually needs to monitor the contents of underground water level, water pumping amount, recharge amount, peripheral surface subsidence and the like on site in time, and adjust the precipitation or recharge scheme in time according to the monitoring result to ensure the safety of the foundation pit and the surrounding environment.
