Ultrafine high-strength inorganic powder rapid grouting reinforcement material and construction process thereof
The invention provides a superfine high-strength inorganic powder rapid grouting reinforcement material and a construction method thereof, and belongs to the technical field of inorganic reinforcement materials. A component A comprising aluminum sulfate cement clinker, 42.5 cement, fly ash, sodium sulfate, a water reducing agent and a retarder and a component B comprising slag powder and sodium metaaluminate are respectively mixed with water in proportion in two stirring barrels, are respectively mixed uniformly by pneumatic stirrers, and then are respectively poured into two slurry containing barrels; the two slurry containing barrels and the independent feeding pipes are communicated with the grouting pump, then the slurry is discharged in the grouting pump in a unified mode to complete grouting, and an obtained consolidated substance product has the advantages of being low in initial viscosity, excellent in coal rock mass permeability and diffusivity, high in solidification speed, rapid in strength development and high in binding power.
本发明提出一种超细高强无机粉体快速注浆加固材料及其施工方法，属于无机加固材料技术领域，通过将包括硫酸铝盐水泥熟料、42.5水泥、粉煤灰、硫酸钠、减水剂和缓凝剂的A组分和包括矿渣粉和偏铝酸钠B组分分别在两个搅拌桶中按比例与水混合，分别用气动搅拌器混合均匀，然后分别倒入两个盛桨桶中，两个盛浆桶分别与独立进料管连通注浆泵，随后在注浆泵中统一排出完成注浆，得到的固结物产品具有初始粘度低，煤岩体渗透扩散性优异，凝固速度快，强度发展迅速，粘结力强的优点。
