Cement-based composite grouting material as well as preparation method and grouting construction method thereof
The embodiment of the invention discloses a cement-based composite grouting material as well as a preparation method and a grouting construction method thereof, relates to the technical field of engineering materials, and aims to solve the problem that a grouting material cannot prevent and treat salt-containing underground water. The preparation method of the cement-based composite grouting material comprises the following steps: sampling underground water in a to-be-grouted area to obtain an underground water sample; the underground water sample is detected, and the salt content of underground water in the to-be-grouted area is obtained; based on the salt content of the underground water, the cement-based composite grouting material comprises the following components in percentage by weight: 1.3%-10.5% of magnesium oxide, 0.66%-0.7% of a water reducing agent, 0.66%-0.7% of an early strength agent, 58.76%-63.44% of Portland cement and 29.38%-31.72% of water. According to the component proportion of the cement-based composite grouting material, all the components of the cement-based composite grouting material are weighed and evenly stirred. The method is suitable for preventing salt-containing underground water.
本发明实施例公开水泥基复合注浆材料及其制取方法和注浆施工方法，涉及工程材料技术领域，为解决注浆材料无法防治含盐地下水的问题而发明。所述水泥基复合注浆材料的制取方法，包括：对待注浆区域的地下水取样获取地下水样；检验所述地下水样，获取所述待注浆区域的地下水含盐量；基于所述地下水含盐量确定水泥基复合注浆材料的组分配比为氧化镁1.3％～10.5％，减水剂0.66％～0.7％，早强剂0.66％～0.7％，硅酸盐水泥58.76％～63.44％，水29.38％～31.72％；根据所述水泥基复合注浆材料的组分配比，称取所述水泥基复合注浆材料的各组分并搅拌均匀。适用于防治含盐地下水。
