High embankment slope stabilizing structure and construction method thereof

Abstract

The invention discloses a high embankment slope stabilizing structure. The high embankment slope stabilizing structure comprises a retaining wall, steel pipe piles and anchor rods; the retaining wallis arranged at the foot of a high embankment slope, concrete-filled steel pipe piles are arranged on the inner surface of the retaining wall, an excavation step and a gravel drainage zone are arrangedat a filling and excavation interface, the bottoms of the concrete-filled steel pipe piles and the steel pipe piles penetrate through the gravel drainage zone, and the upper sections of the steel tube piles are sleeved with grouting sleeves correspondingly; the lower end of the grouting sleeves extend to the gravel drainage zone, the upper end of each grouting sleeve is connected with a groutingopening through a grouting pipe, a fixed pulley and a pipeline channel are arranged inside each concrete-filled steel pipe pile, the anchor rods are is fixed in a rock stratum behind the excavation step, the exposed parts of the tops of the anchor rods are connected with steel strands, and the steel strands are connected to the fixed pulleys or the steel pipe piles at the same height; the steel strands connected to the fixed pulleys are led out of crown beam through the pipeline channel and connected with a steel strand tensioning device. The high embankment slope stabilizing structure is suitable for reinforcing and active control of embankment deformation in the embankment construction and operation process, and is particularly suitable for embankment projects with high requirements forembankment 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
