Description

Technical Field

[0001] The utility model relates to the technical field of slope anti-slip, in particular to an anti-slip supporting device for an embankment slope. Background Art

[0002] Anti-slip support devices for fill embankment slopes are key engineering facilities for ensuring slope stability and preventing landslides. They utilize the embedded strength of piles in stable rock and soil to support the sliding mass, sharing the downward force of the landslide between the piles and the stable rock mass. These devices minimize disturbance to the sliding mass, are easy to operate, require a short construction period, achieve rapid results, minimize disruption to traffic, and are safe and reliable. These devices are typically constructed by excavating or drilling holes, inserting a reinforced concrete frame, and pouring concrete. The anchoring depth below the sliding surface is determined based on the active earth pressure exerted on the pile by the sliding mass, the passive earth pressure in front of the pile, and the rock and soil properties.

[0003] Previous anti-slip support devices for fill embankment slopes have the following drawbacks: 1. They are difficult to assemble on-site, and the angle of the support baffles cannot be adjusted to precisely fit the slope surface to meet varying usage requirements. Therefore, those skilled in the art have provided an anti-slip support device for fill embankment slopes to address the issues raised in the background art. Utility Model Content
