Water level stabilizing device for dynamic balance control construction method for water levels inside and outside deep foundation pit

The invention discloses a dynamic balance control construction method for water levels inside and outside a deep foundation pit. The method comprises the following specific steps that recharge well setting points are designed and planned; the drilling depth is to enter a strongly-weathered rock surface; after drilling to the designed length, hole cleaning is conducted on the well bottom, and hole cleaning is conducted in a slurry circulation mode; installing, correcting and fixing the well casing; finally, the well pipe is communicated with the recharge module; and the control center counts water level information of all the recharge wells and the water pumping condition in the foundation pit, and then controls the underground water level outside the foundation pit and the water level in the recharge wells to achieve dynamic balance of the water level rising amplitude. By means of the construction method, the recharge water amount and the recharge pressure of the recharge well can be effectively controlled, u
