Problems solved by technology

[0007] In addition, during the construction of steep slope subgrades, a large amount of excavation and waste dregs will be generated, and the accumulation of waste dregs will damage surface vegetation, induce soil erosion, and ultimately endanger the surrounding ecological environment

Embodiment Construction

[0075] With reference to the accompanying drawings, a method for jointly protecting steep slope subgrades with anti-slide piles and high gabion retaining walls comprises the following steps:

[0076] (1) Excavation and disposal of dregs to regenerate material sources at all levels

[0077] At the construction site of the steep slope subgrade, sorting, crushing and screening techniques are used sequentially to regenerate the excavated muck on site to obtain stone materials for filling gabion cages and backfill sources for steep slope subgrades. Filler sources include various recycled materials in different particle size ranges;

[0078] The stone: requires hard texture, clean surface, certain durability, compressive strength not less than 30MPa, apparent density>2.5g / cm 3 , porosity <20%, particle size controlled at 12-30cm, stone material with material diameter greater than 30cm or less than 12cm, controlled at 4.5%-5.5%;

[0079] The backfill source is designed using the Ta...

Abstract

A method for jointly protecting a steep slope subgrade with an anti-slide pile and a gabion high retaining wall, comprising the following steps: (1) excavating and discarding dregs to regenerate material sources at all levels; (2) constructing anti-slide piles (3); installing concrete retaining boards ; (4) Construction of Gabion High Retaining Wall; (5) Process cycle; (6) Greening of the surface of Gabion High Retaining Wall. The anti-slide piles of the present invention, the gabion net cage and the compacted filling act together to form an integral structure that bears the load together, thereby enabling the steep embankment side slope to maintain lasting stability and long-term safe operation; and the combined slope protection of the present invention can The Gabion high retaining wall is steep and stepped, which reduces the amount of earthwork and surface damage for slope cutting, and saves filler, land and vegetation resources. At the same time, the stone pores of the gabion retaining wall can be implanted into soil and vegetation, which is beneficial to slope greening and ecological restoration, and produces landscape, ecological and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of slope protection in geotechnical engineering, and in particular relates to a construction method for combined protection of steep slope subgrades with anti-slide piles and gabion high retaining walls. Background technique [0002] When building roads in mountainous or hilly areas, due to complex geological, topographical and topographical conditions, geological disasters such as side slope landslides often occur on high-fill steep slope subgrades. For this reason, reinforced high retaining walls are commonly used for steep slope subgrade slope protection. However, there are many defects in the reinforced high retaining wall, including: (1) seepage damage due to poor drainage; (2) “bulging” of the surface wall due to grid creep; (3) environmental incongruity caused by masonry protection. [0003] In the invention patent of "Construction method of river reinforced gabion permeable geotextile composite ecol...
