Abstract

The invention relates to a construction method for fast-setting polymer grouting to quickly control collapsed hillocks. The scheme includes the following construction steps: excavating at least one side slope horse track on the collapsed hillside slope; drilling a plurality of anchor holes on the collapsed hillside slope ; Insert the ground anchor into each anchor hole and perform polymer grouting to form a polymer anchor; Lay the steel mesh on the surface of the collapsed hillside slope and connect and fix it with the end of each ground anchor, and the steel mesh is connected to the There are several spacers between the surface of the collapsed hillside slope; two-component intumescent polymer grouting material is sprayed on the steel wire mesh to form a high polymer anti-scour layer; drills are drilled on the collapsed hillside slope through the mesh of the steel mesh. Take a plurality of planting holes; fill each planting hole with mixed nutrient soil of grass seeds; set a plurality of inclined drainage holes inwardly and upwardly from the high polymer anti-scour layer, this method has the advantages of short construction period, ecological environment protection and convenient construction And the advantages of high strength and strong erosion resistance.

Description

technical field [0001] The invention relates to the field of geological disaster control, in particular to a construction method for quick-setting polymer grouting to quickly control collapsed hillocks. Background technique [0002] Due to the deep weathered parent material residues in the granite area in southern my country, the weak anti-erosion ability of the soil, the steep terrain, the heavy rainfall and the induction of human-made vegetation damage, the granite collapse and granite erosion phenomenon in southern China has a wide distribution, rapid development, It has the characteristics of strong suddenness and great harm, posing a huge threat to people's life and property. [0003] Most of the existing ecological management ideas and engineering management measures are based on experience or semi-empirical and semi-theoretical basis, lacking rigorous theoretical basis, especially the research on soil characteristics and erosion process has not been systematic, The re...
