Water-rich tunnel grouting slurry and grouting process
The invention relates to the field of tunnel grouting materials and grouting technologies, and particularly discloses water-rich tunnel grouting slurry and a grouting technology, the slurry is prepared from cement composite slurry and water glass, and the volume ratio of the cement composite slurry to the water glass is 4: (1-3); the cement composite slurry raw material comprises 40 parts of cement; 55-70 parts of a filler; 48 to 82 parts of water; 0.4 to 1.2 parts of a water reducing agent; 0.5 to 1.5 parts of an anti-corrosion agent; 1.3 to 2.7 parts of an anti-cracking agent; the anti-corrosion agent comprises the following raw materials in parts by weight: 10 parts of basalt short fibers; 1-3 parts of bagasse powder; 1.5 to 4.5 parts of dicyclopentadiene; 3-8 parts of an insoluble polymer; 0.01 part of a polymerization inhibitor; and the baume degree of the water glass is 30 Be-39 Be. An advancing type deep hole grouting technology is adopted, and the grout is used for grouting. The method has the effect of improving the water erosion resistance of the surrounding rock.
本申请涉及隧道注浆料与注浆工艺领域，具体公开了一种富水隧洞注浆浆液及注浆工艺，浆液由水泥复合浆料和水玻璃制成，水泥复合浆料与水玻璃的体积比为4：（1‑3）；水泥复合浆料原料包括水泥40份；填料55‑70份；水48‑82份；减水剂0.4‑1.2份；抗溶蚀剂0.5‑1.5份；抗裂剂1.3‑2.7份；抗溶蚀剂包括以下重量份的原料：玄武岩短纤维10份；甘蔗渣粉1‑3份；双环戊二烯1.5‑4.5份；不溶性聚合物3‑8份；阻聚剂0.01份；水玻璃的波美度为30Bé‑39Bé。采用前进式深孔注浆工艺，使用上述浆液进行注浆。本申请具有提高围岩的抗水蚀性能的效果。
