Retaining wall drainage method and retaining wall drainage system

Abstract

The invention relates to a retaining wall drainage method and a retaining wall drainage system. The retaining wall drainage method comprises the following steps that when an original drainage hole in a retaining wall is blocked, a drainage well is arranged in a soil body blocked by the retaining wall along the longitudinal direction; the originally blocked water drainage hole is selected as a foundation hole, a water guide pipe is inserted into the foundation hole, and the water guide pipe is anchored into the drainage well, so that the water guide pipe can guide out water in the drainage well; therefore, the purpose of draining is achieved, and water drainage capacity of the retaining wall is recovered. Moreover, in the process of recovering the water drainage capacity of the retaining wall, and the originally blocked water drainage hole is directly used as the foundation hole, so that the cost required for recovering the water drainage capacity of the retaining wall is effectively reduced, and meanwhile, the whole process is simpler and easier to implement. Moreover, by adopting the drainage well and the water guide pipe, the water drainage capacity of the retaining wall can be recovered for a long time, and the retaining wall is not easy to block.

Description

technical field [0001] The invention relates to the construction field of retaining wall drainage engineering, in particular to a retaining wall drainage method and a retaining wall drainage system. Background technique [0002] In construction fields such as roads or bridges, by setting a retaining wall on one side of the slope or filling, the soil is blocked on the side of the retaining wall, so as to achieve the purpose of shaping the soil and avoiding the loss of filling. In order to allow the accumulated water in the soil blocked by the retaining wall to be discharged smoothly, a weep hole will be provided in the retaining wall, and the weep hole will pass through both sides of the retaining wall to drain the accumulated water in the soil. Water drains. However, after a period of use, the drain hole is easily blocked, causing the accumulated water on one side of the retaining wall to be unable to be discharged. When the accumulated water increases, especially after he...

AI Technical Summary

Problems solved by technology

However, after a period of use, the drain hole is easily blocked, resulting in the accumulation of water on the side of the retaining wall cannot be discharged

When the accumulation of water increases, especially after the heavy rain, the retaining wall needs to bear the huge pressure from the side of the soil, and the retaining wall is prone to collapse
