A high embankment slope stabilization structure and construction method

Abstract

The invention discloses a high embankment slope stabilization structure, which comprises: a retaining wall, steel pipe piles and anchor rods; a retaining wall is arranged at the slope foot of the high embankment; Excavation steps and gravel drainage belts are set at the interface, the bottoms of the steel pipe concrete piles and steel pipe piles pass through the gravel drainage belts, the upper section of the steel pipe piles is covered with a grouting sleeve, and the lower end of the grouting sleeve reaches the broken stone drainage belt. The upper end of the stone drainage belt is connected to the grouting port through the grouting pipe. The fixed pulley and the pipeline channel are arranged inside the steel pipe concrete pile. The anchor rod is fixed in the rock stratum behind the excavation steps. The strands are connected to fixed pulleys or steel pipe piles at equal heights, and the steel strands connected to the fixed pulleys are led out of the crown beam through the pipeline channel and connected to the steel strand tensioning device. It is suitable for reinforcement and active control of embankment deformation during embankment construction and operation, especially for embankment projects with high requirements for embankment stability and later operation safety.

Description

technical field [0001] The invention belongs to the technical field of embankment engineering reinforcement and protection, and in particular relates to a high embankment slope stabilization structure and construction method, which is suitable for reinforcement and active control of embankment deformation during embankment construction and operation, especially for embankment stability and later operation safety It is especially suitable for embankment projects with high requirements. Background technique [0002] Half-fill and half-cut highway embankment is a common construction method in the process of road construction in mountainous areas. Due to the large difference in mechanical properties between the embankment filling material and the rock and soil on the slope surface of the mountain, slippage easily occurs at the interface between filling and excavation. To cause safety accidents such as embankment collapse, certain measures must be taken for reinforcement during t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a high embankment slope stability structure and construction method to solve the main problems in the existing anti-slip reinforcement technology of high embankments near mountains, such as poor reinforcement effect, relatively limited by site conditions, difficult drainage, and construction problems. Problems such as high cost, single reinforcement method, and difficult control of post-operation security
