| description | The invention discloses a deep foundation pit bottom plate post-cast strip drainage and water supply circulation system construction method. The method comprises the following steps that S10, construction preparation and measurement are conducted; s20, a groove below a post-cast strip and a bottom plate cushion layer is excavated and built, and a main blind pipe is manufactured and placed; s30, the periphery of the blind pipe is wrapped and backfilled with a gravel permeable layer; s40, sand-lime bricks are laid on the two sides of the post-cast strip in a masonry mode, and variable-section connectors are installed so that the PVC50 blind pipes can be communicated with the PVC110 main blind pipes at the bottoms of the grooves; s50, the PVC blind pipe is wrapped with multiple layers of geotechnical cloth; and S60, after the strength of the cushion layer meets the requirement, construction of a waterproof layer, a protective layer and other working procedures is conducted. The method has the beneficial effects |
