Deep foundation pit drainage system

Abstract

The invention discloses a deep foundation pit drainage system which comprises a seat stand structure, a vertical lifting supporting assembly, a cross beam rod, a walking trolley water absorption assembly and a balance assembly. The cross beam rod is rotationally arranged at the top end of the vertical lifting supporting assembly, the vertical lifting supporting assembly is used for adjusting the height of the cross beam rod, the seat stand structure is arranged at the bottom end of the vertical lifting supporting assembly, and the seat stand structure is used for achieving horizontal rotation of the vertical lifting supporting assembly; the balance assembly is arranged between the seat stand structure and the cross beam rod, the position of a water pool can be changed ceaselessly due to engineering proceeding at the low position of the water pool at the bottom of the deep foundation pit, the horizontal angle of the vertical lifting supporting assembly is adjusted through the seat stand structure, and the walking trolley water suction assembly moves in the axial direction of the cross beam rod; therefore, the drainage position can be rapidly adjusted and changed, the labor intensity of workers is greatly reduced, and rapid drainage can be achieved in rainy days in rainy seasons.

Description

technical field [0001] The invention belongs to the technical field of foundation pit drainage, and in particular relates to a deep foundation pit drainage system. Background technique [0002] Deep foundation pit engineering refers to the earthwork excavation, support, and dewatering engineering of foundation pits whose excavation depth exceeds 5m (including 5m), or the excavation depth does not exceed 5m, but the geological conditions, surrounding environment and underground pipelines are complicated, or Excavation and support of foundation pits that affect the safety of adjacent buildings. [0003] The Chinese patent with the application number CN202010451144.4 discloses a super-large deep foundation pit drainage system, including a drainage ditch around the foundation pit, and a drainage hole is provided in the drainage ditch, and a water pump is arranged in the drainage hole. The water pump is connected with a drain pipe protruding from the drain hole, and the upper en...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the progress of the project, the position of the water puddle at the bottom of the deep foundation pit will change continuously. It is often necessary to move the drainage equipment. In the rainy season, the labor intensity of the workers is greatly increased, and the Not conducive to rapid drainage;

[0005] 2. Cannot automatically adjust and change the drainage position
