Double-liquid quick-setting grouting reinforcement inorganic material and construction process
The invention discloses a double-liquid quick-setting grouting reinforcement inorganic material and a construction technology, and belongs to the technical field of coal mine grouting reinforcement. Comprising a component A and a component B. The component A comprises the following components in parts by weight: 15-30 parts of cement, 20-40 parts of a plugging agent, 3-10 parts of an inorganic capillary crystalline active master batch, 40-50 parts of fly ash and 0.3-0.5 part of cellulose ether; the component B comprises the following components in parts by weight: 30-50 parts of calcium oxide, 40-60 parts of talcum powder, 8-10 parts of an accelerator and 0.5-1 part of a naphthalene-based superplasticizer; the inorganic materials of the component A and the component B are weighed according to parts by weight, respectively added with water, mixed and stirred, and then mixed according to a weight ratio of 1: 1 to be used for grouting reinforcement. According to the formula, a double-component inorganic material is adopted, the performance defects of high-temperature reaction, inflammability, toxicity and corrosivity of a polymer grouting material are overcome, the reaction speed is high, the grouting effect is improved, meanwhile, the strength is rapidly increased, and the engineering requirements of rapid advancing of a working face and rapid deformation of a roadway are met.
本发明公开了一种双液速凝注浆加固无机材料及施工工艺，属于煤矿注浆加固技术领域；包括A组份和B组份的双组份无机材料，按重量份数计：A组分包括15‑30份的水泥、20‑40份的堵漏剂、3‑10份的无机渗透结晶活性母料、40‑50份的粉煤灰和0.3‑0.5份的纤维素醚；B组分包括30‑50份的氧化钙、40‑60份的滑石粉、8‑10份的速凝剂和0.5‑1份的萘系高效减水剂；按重量份数称量A组份和B组份无机材料，分别加水混合搅拌后，再按重量比为1：1的比例混合后可用于注浆加固。本发明配方采用双组份无机材料，克服了高分子注浆材料所存在的反应高温、可燃、有毒、有腐蚀性的性能弊端，且反应速度较快，提高注浆效果，同时强度增长迅速，满足工作面快速推进和巷道快速变形的工程需要。
