Portland cement-based tunnel waterproof grouting material as well as preparation method and application thereof
The invention relates to a Portland cement-based tunnel waterproof grouting material and a preparation method and application thereof, and belongs to the technical field of underground engineering, and the grouting material comprises the following components in parts by weight: 30 to 50 parts of PO42.5 Portland cement, 1.8 to 3 parts of sodium-based bentonite, 0.03 to 0.15 part of sodium methyl silicate, 0.06 to 0.25 part of hydroxypropyl methyl cellulose ether, 0.15 to 0.35 part of sodium sulfate, 0.009 to 0.04 part of triisopropanolamine, and 0.006 to 0.01 part of lithium carbonate. The paint is prepared from the following components in parts by weight: 0.06 to 0.1 part of polyethylene glycol 400, 0.06 to 0.1 part of styrene-butadiene latex powder, 0.03 to 0.15 part of VAE latex powder, 0.3 to 0.5 part of tributyl phosphate and 30 to 50 parts of water. The prepared grouting material has excellent dispersion resistance and higher mechanical property, flowability and setting percentage, and can realize efficient filling of tunnels.
一种硅酸盐水泥基隧道防水注浆材料及其制备方法和应用，属于地下工程技术领域，按照重量份数计，该注浆材料由以下组分组成：PO42.5硅酸盐水泥30～50份，钠基无基膨润土1.8～3份，甲基硅酸钠0.03～0.15份，羟丙基甲基纤维素醚0.06～0.25份，硫酸钠0.15～0.35份，三异丙醇胺0.009～0.04份，碳酸锂0.006～0.01份，聚乙二醇400 0.06～0.1份，丁苯乳胶粉0.06～0.1份，VAE乳胶粉0.03～0.15份，磷酸三丁酯0.3～0.5份，水30～50份。本发明所制备的注浆材料具有优良的抗分散性能，以及更高的力学性能、流动性和结实率，能够实现隧道高效充填。
