Composite anti-sliding pile wall retaining structure suitable for reservoir bank slope and construction method

Abstract

The invention relates to a composite anti-sliding pile wall retaining structure suitable for a reservoir bank slope and a construction method. The structure comprises an anti-sliding pile group and a retaining wall; the anti-sliding pile group is vertically arranged between the retaining wall and the reservoir bank slope face and supports the retaining wall, the upper end of the anti-sliding pile group and the bottom end of the retaining wall are fixedly connected, the lower end of the anti-sliding pile group stretches downwards and is embedded in an anti-sliding stratum below a reservoir bank slope sliding band; the anti-sliding pile group is embedded in the anti-sliding stratum below the reservoir bank slope sliding band, the anti-sliding stability needs can be met, the pile top gravity type concrete retaining wall manner is adopted, the lower grouting type anti-sliding pile group and the pile peripheral soil are integrated, and the anti-sliding pile group and the upper gravity type retaining wall are connected to form the composite anti-sliding pile wall. Integrality is good, space effect is optimized structurally, and stress is more reasonable.

Description

technical field [0001] The invention relates to the technical field of geological disaster prevention and control engineering of reservoir bank wading slopes, in particular to a composite anti-sliding pile wall support structure and construction method suitable for reservoir bank slopes. Background technique [0002] The level of my country's hydropower construction ranks among the top in the world. For example, the completed Three Gorges Project is the largest water conservancy hub in the world. However, while the Three Gorges and other water conservancy projects have brought us good social and economic benefits such as flood control and power generation, they have also aggravated the crisis in the reservoir area. Geological disasters, among which reservoir collapse is one of the most common engineering geological disasters. At present, the commonly used reservoir bank slope control measures are mostly similar to mountain slopes, such as slope cutting and unloading, anti-sli...

AI Technical Summary

Problems solved by technology

Since the reservoir bank slope is a wading slope and the water level is greatly affected by the operation of the reservoir water level, when the treatment range of the reservoir bank slope is below the water level and the depth of the landslide body (bank collapse) is relatively large, slope cutting and unloading, Tr
