Abstract

The invention relates to a vertical shaft construction method, and belongs to the technical field of foundation pit engineering construction. The method includes the steps that (1) a vertical shaft space which comprises a bottom wall and a side wall is excavated; (2) a mounting groove is formed in the bottom wall of the vertical shaft, and a water collecting tank is placed in the mounting groove;(3) a water collecting pipe and a drainage pipe are mounted on the water collecting tank, a filter screen is mounted at a pipe orifice of the water collecting pipe, and a valve is mounted on the drainpipe; (4) a hydraulic cylinder and a push plate are installed beside the drainage pipe on the upper surface of the bottom wall; and (5) a collection pit for containing silt and other impurities is formed in the upper surface of the bottom wall, and a door plate for opening and closing the collection pit is arranged at a pit opening of the collection pit. The vertical shaft construction method hasthe effect of reducing the possibility that the silt and other impurities block the upper surface of the filter screen.

Description

technical field [0001] The present application relates to the technical field of foundation pit engineering construction, in particular to a shaft construction method. Background technique [0002] The bottom of the shaft is the key part of the shaft. During construction and operation, usually due to the seepage of groundwater, the shaft wall often has a certain degree of leakage water, and most of the leakage water on the shaft wall will collect to the bottom of the shaft along the shaft wall. The accumulated water will reduce the structural strength at the bottom of the shaft, and in severe cases, the shaft wall will crack. [0003] The Chinese utility model patent with the authorized announcement number CN207453968U discloses a shaft bottom structure, including a shaft structure and a drainage structure; the shaft structure includes the bottom of the well, and the drainage structure is arranged at the bottom of the well; , the entrance of the central drainage pipe is set...
