Grouting material for water conservancy and hydropower engineering and grouting method thereof
The invention provides a grouting material for water conservancy and hydropower engineering and a grouting method thereof, and relates to the technical field of water conservancy and hydropower engineering foundation grouting. The grouting material for water conservancy and hydropower engineering comprises the following raw materials in parts by weight: 10-20 parts of epoxy resin, 35-45 parts of slag powder, 25-35 parts of fly ash, 5-10 parts of silica fume, 5-10 parts of acetone, 20-25 parts of a mixed solution, 1-3 parts of a water reducing agent, 2-3 parts of an accelerant, 0.1-0.3 part of a water-retaining agent, 3-5 parts of a cross-linking agent and 1-4 parts of a flow promoter, and the cross-linking agent is one of polyethylene glycol allyl ether and polyethylene glycol acrylate. The epoxy resin, the slag powder, the fly ash and the silica fume are used as main preparation raw materials, and meanwhile, a certain component of acetone and a mixed solution of magnesium acrylate, calcium acrylate and sodium acrylate are added, so that the physical performance of the prepared grouting material is obviously improved, fine gaps in a water conservancy and hydropower foundation can be effectively filled, and the service life of the grouting material is prolonged. The grouting effect is good.
本发明提供一种水利水电工程用灌浆材料及其灌浆方法，涉及水利水电工程基础灌浆技术领域。该水利水电工程用灌浆材料，包括以下重量份原料：环氧树脂10～20份、矿渣粉35～45份、粉煤灰25～35份、微硅粉5～10份、丙酮5～10份、混合溶液20～25份、减水剂1～3份、促进剂2～3份、保水剂0.1～0.3份、交联剂3～5份、流动助剂1～4份，所述交联剂为聚乙二醇烯丙基醚和聚乙二醇丙烯酸酯中的其中一种。通过使用环氧树脂、矿渣粉、粉煤灰和微硅粉作为主要制备原料，同时添加一定成分的丙酮和丙烯酸镁、丙烯酸钙、丙烯酸钠混合溶液，使得制作而成的灌浆材料物理性能得到明显提升，能够对水利水电基础内的细小缝隙进行有效填充，灌浆效果好。
