Filling and solidification slurry and horizontal directional drilling grouting anti-collapse process
The invention discloses filling and solidification slurry and a horizontal directional drilling grouting anti-collapse process. The filling and solidification slurry comprises drilling bentonite, cement, fine sand and a viscosity reducer. After horizontal directional drilling pipe dragging is completed, the filling and solidification slurry is injected into gaps between strata and pipelines belowcanals and highways, spaces are filled and solidified, and collapse is prevented.
本发明公开一种填充固化泥浆及水平定向钻注浆防塌工艺，填充固化泥浆包括钻井膨润土、水泥及细沙、降粘剂。水平定向钻拖管完成后，将本发明的填充固化泥浆注入到水渠、公路下方的地层与管道空隙中，填充、固化空间，防止塌陷。
