Intelligent full-automatic recharging system of underground water on outer side of deep foundation pit and construction method

Abstract

The invention relates to an intelligent full-automatic recharging system of underground water on the outer side of a deep foundation pit and a construction method. The underground water extracted from all dewatering wells is collected, then precipitated and stored in a water tank, and the water tank is connected with pipelines of the recharging system; when recharging needs to be conducted, the underground water stored in the water tank automatically recharges to a recharging well; when the water level in a observation well declines to a warning water level, a liquid level monitoring measurement instrument outputs a signal to an alertor immediately, the alertor starts an alternating current contactor, an electromagnetic valve power supply is connected, a valve is started, and water injection is conducted on the recharging well; and after the water level in the observation well reaches the normal water level, a liquid level transmitter outputs a signal to the alertor, the alertor starts the alternating current contactor, the electromagnetic valve power supply is cut off, and recharging is completed. Technologies of recharging water tank automatic water supplement, water level automatic monitoring and giving an alarm, and automatic starting and closing of recharging are adopted in the whole process, intellectualization and full-automation of the whole underground water recharging system are achieved, and the timeliness and the quality of recharging are ensured.

Description

technical field [0001] The invention relates to an intelligent automatic recharge construction method for groundwater outside a deep foundation pit. The invention belongs to the technical field of intelligent automatic recharge construction for groundwater outside a deep foundation pit and is suitable for dewatering and recharge construction for foundation pits. Background technique [0002] There are more and more deep foundation pit projects in construction engineering, especially in areas with high groundwater levels, it is necessary to dewater the groundwater inside the foundation pit to facilitate construction. In order to reduce the influence of precipitation inside the foundation pit on the settlement and deformation of buildings and structures around the outside of the foundation pit, it is necessary to supplement and recharge the groundwater outside the foundation pit. At present, the construction method of groundwater recharge outside the foundation pit is mainly t...
