Abstract

The invention discloses a quick-setting type adjustable gel grouting material and application thereof. The quick-setting type adjustable gel grouting material comprises the following components in parts by weight: 100 parts of cement, 0.05-0.8 part of a water reducer, 0.05-0.8 part of a thickening agent, 0.06-0.8 part of a coagulant, 0.07-0.9 part of a retarder, 0.05-0.8 part of a tackifier and 0.01-1 part of a water-retaining agent, wherein the cement is a sulfur-lithium-acid salt cement; the water reducing agent is a polycarboxylate water reducer, a melamine water reducer or a naphthalene water reducer; wherein the thickening agent is hydroxypropyl methyl cellulose or hydroxymethyl propyl cellulose; the coagulant is aluminum carbonate or calcium formate; the retarder is boric acid or citric acid or tartaric acid; and the tackifier is glue essence ( with the component of PVA or PVE). According to the anchor rod grouting material disclosed by the invention, the initial setting can be realized within 20 minutes, and middle setting can be realized within 25-40 minutes, so that blasting operation and engineering construction in a tunnel are synchronously carried out, the constructionprogress is improved, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fast-setting adjustable setting grouting material and its application. Background technique [0002] my country is the country with the largest tunnel project scale, the largest number and the fastest construction speed in the world. By the end of 2016, 14,040km / 15,181 road tunnels had been built, and by the end of 2017, 15,781km / 14,700 railway tunnels had been built. By 2020, the mileage of my country's high-speed railways will reach 30,000 kilometers (the existing 22,000 kilometers). Kilometers; 150,000 kilometers of highways will be built (the existing 131,000 kilometers), and 19,000 kilometers will need to be added. In addition, the plan also pointed out that the transportation development in the central and western regions has obvious shortcomings and is relatively lagging behind, and the construction of corridors in the central and western regions should be str...
