Summary:The invention discloses a pit waterproof construction dewatering processing method for an underground building in an environment with rich water resources. The method includes the processes of arranging a dewatering pit, a water suction pump and a covering plate, injecting graded sand and stone, and concrete, and the like, and solves the problems that in an environment with rich shallow layer water resources at the bottom of an underground space foundation, recharging of internal accumulating water in the positions of a water collecting well, an elevator shaft, a pile cap well and the like below an underground cushion layer is active; on the one hand, operation of a waterproof layer on the construction side in an open-water-free environment can not be guaranteed, and consequently the waterproof layer can not be constructed on a well bottom base surface; and on the other hand, due to the accumulating water, structure concrete at bottom plates of the water collecting well, the elevator shaft and the pile cap we
