Abstract

The invention relates to a polymer multi-edge pile grouting method for highway slope protection and landslide treatment. The polymer multi-edge pile grouting method includes the following specific implementation steps: (1) pile position arrangement; (2) multi-edge drilling tool manufacturing, and pile position hole-forming; (3) grouting pipe installation; (4) grouting improvement of polymer; and (5) pile forming. According to engineering geological characteristics, the multi-edge drilling tool with three edges or four edges is manufactured, a static hole pressing mode is adopted, multi-edge body pile holes are formed in a landslide mass through pressing, two-component swelling polymer grouting materials are injected in the multi-edge body pile holes, after polymer materials have chemical reaction, volume of the polymer materials is swelled rapidly, the polymer materials are solidified so as to fill the multi-edge body pile holes, and peripheral rock-soil bodies are adhered and compacted so as to form a polymer multi-edge pile with strong anti-skidding capacity. The polymer multi-edge pile grouting method has the advantages of being free of water reaction, strong in adaptability, high in pulling and shearing resistance, small in slope disturbance, rapid to construct, economical, durable and the like and has huge economic and social benefits and wide development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of side slope protection and landslide treatment, and in particular relates to a polymer multi-edge pile grouting method for road side slope protection and landslide treatment. Background technique [0002] my country is a country where geological disasters occur frequently. Every year, the number of deaths and missing people caused by geological disasters accounts for about 1 / 3 of the total number of natural disasters, and the direct economic losses caused by them are as high as tens of billions of yuan. Among them, landslide disasters are the most frequent and harmful type of geological disasters, accounting for 50%-60% of the total number of geological disasters. Once a large-scale landslide disaster occurs, it often leads to interruption of traffic, blockage of rivers, destruction of factories and mines, and burial of villages and towns, resulting in serious loss of life and property and environmental da...
