Water-guiding grouting material, preparation method thereof and water-guiding grouting stone body
The invention discloses a water-guiding grouting material, a preparation method thereof and a water-guiding grouting stone body. The invention discloses a water-guiding grouting material which is mainly composed of a cementing material, fine aggregate, a foaming agent and water. The particle size of the fine aggregate is less than 3 mm, and the mass ratio of the fine aggregate to the cementing material is (4-7): 1; and the foaming agent accounts for 0.5-1% of the mass of the cementing material. The invention also provides a preparation method of the water-guiding grouting material and a water-guiding grouting stone body. The water-guiding grouting material comprises the foaming agent and the high-content fine aggregate and has water guiding performance, a drainage high-strength pile body which has a certain diameter, is a stone body and can guide water can be formed in a sludge foundation through a grouting method, pore water in sludge can be continuously guided and discharged in construction and after construction, and drainage consolidation of sludge soil between the piles is accelerated.
一种导水注浆材料及其制备方法、导水注浆结石体。本发明公开了一种导水注浆材料，主要由胶凝材料、细骨料、发泡剂和水组成；所述细骨料的粒径小于3mm，所述细骨料与胶凝材料的质量比为(4‑7)：1；所述发泡剂为胶凝材料质量的0.5‑1％。本发明还提供一种上述导水注浆材料的制备方法和一种导水注浆结石体。本发明的导水注浆材料包括发泡剂和高含量的细骨料，具有导水性能，通过注浆方法可在淤泥地基中形成既具有一定直径且结石体又可以导水的排水高强度桩体，在施工中与施工后均能持续导排淤泥中孔隙水，加快桩间淤泥土的排水固结。
