AI Technical Summary
Technical Problem
In existing technologies, the permeable holes of drainage pipes are easily blocked by soil, resulting in a decrease in drainage efficiency.
Method used
A multi-layer soil nailing wall deep foundation pit support system was designed, which uses components such as drainage pipes, installation rings, support columns, dredging columns and control components. By rotating the drainage pipes, the support columns drive the dredging columns to dredge the permeable holes, and the scraper removes the soil in the holes to improve drainage efficiency.
Benefits of technology
It effectively unclogs permeable holes, increases the drainage speed of drainage pipes, reduces the impact of soil on drainage pipes, and improves drainage efficiency.

Abstract
The application discloses a multi-layer soil-nailing wall deep foundation pit support, relates to the technical field of foundation pit support, and comprises a drain pipe, the drain pipe is formed with at least three water-permeable holes; a mounting ring, the inner wall of the mounting ring is formed with support grooves corresponding to support columns one by one and allowing the support columns to slide, the outer diameter of the drain pipe is smaller than the inner diameter of the mounting ring; a connecting column, the connecting column is provided with a support plate away from one side of the mounting ring; a mounting block, the mounting block is arranged on the inner circumferential side wall of the mounting ring, the mounting block is axially dislocated with the support column along the drain pipe; a dredging column, the dredging column passes through the water-permeable hole, when the support column abuts against the groove wall away from one side of the mounting block, the dredging column is aligned with the water-permeable hole; a control assembly, when the support column is slidably abutted to the groove wall away from one side of the mounting block, the control assembly controls the dredging column to pass through the water-permeable hole; a reset assembly, when the dredging column passes through the water-permeable hole, the reset assembly drives the dredging column to slide to a position before passing through the water-permeable hole in the direction of the mounting block. The application can dredge the water-permeable hole of the drain pipe.
