Embodiment Construction

[0028] A damaged mountain repair method combining anti-slide piles and geogrids, the steps of which are as follows:

[0029] 1) Filling soil: Clean up the damaged surface of the mountain, and use the filling soil to fill up to the original elevation of the mountain through layered rolling; specifically: every 500mm is a layer for leveling and compacting, The compaction coefficient is greater than or equal to 0.90.

[0030] 2) Pile formation of anti-slide piles: A new type of pile formation process is adopted in which the rock-socketed part is formed first, and then the piles are connected after filling and compacting. The rock-socketed part of the pile body is piled by bored piles at one time; the pile body in the filled soil is piled by segmented piles.

[0031] The lower part of the anti-slide pile is embedded in the original bedrock surface for 6m, the top is buried for 3m, and the section diameter is 1.5m. The pile body is made of C30 concrete; φ10@150 layout.

Abstract

The invention discloses a slide-resistant pile and geogrid combined damaged mountain repair method and structure, and belongs to the technical field of damaged mountain environmental government. A repaired mountain is formed through soil filling based on an original damaged mountain, a side slope and a sliding face exit after filling, multiple rows of slide-resistant piles are arranged on the middle and front portions of the side slope, reinforced concrete coupling beams are arranged at the tops of the slide-resistant piles, the slide-resistant piles are inserted into the lower portion of thesliding face of the side slope and embedded into stable original bed rock, and horizontally-laid geogrid reinforcing areas are arranged on the top of the filled mountain. By means of the structure andthe method, the slide-resistant piles and geogrids are combined to resist sliding to ensure overall stability of the mountain. A supporting structure which combines a support and reinforcement ribs and is easy to construct and high in slide resistance is formed on the side slope, and the overall side-resistant effect is achieved on the filled mountain.

Description

technical field [0001] The invention relates to a side slope support system for mountain repair, in particular to a damaged mountain repair method and structure in which anti-slide piles and geogrids are combined. Background technique [0002] Mountains are precious ecological resources, which can purify the air, beautify the environment, enrich the natural life of the city, and provide people with a good living environment. But for a long time, due to the continuous quarrying of mountains, many large areas of exposed and damaged mountains have been left behind, which has seriously damaged the picturesque natural landscape and caused a series of serious ecological environment damage. Restoration of damaged mountains has become an important task for geological disaster management and ecological environment restoration. The outstanding problem in the mountain restoration project is that after the restoration of the original mountain shape, the physical and mechanical properti...
