Weak stratum tunnel advanced deep-hole grouting reinforcement material
The invention discloses a weak stratum tunnel advanced deep-hole grouting reinforcement material. The material comprises the following raw materials by weight percentage: 50% of clinker, 3.8% of limestone, 4% of ore powder, 5.5% of desulfurized gypsum, 0.7% of calcium oxide, 0.6% of silica-gel powder, 4% of glass bead, 11% of zeolite, 3% of cellulose ether, 5% of a concrete expanding agent, 0.7% of polypropylene fiber, 0.7% of steel fiber, 1% of an accelerator and 10% of water. The material has the advantages that while in use, the material is pressed in a hole grouting zone by high pressure, the grouting material is rapidly solidified, the material forming a paste body has the advantages of good fluidity and groutability, is easily grouted into a tunnel surrounding rocks stratum, gelation time is adjustable, stability is good, water permeability of a solidified body is very low, tunnel surrounding rocks can be solidified, and stability of the tunnel surrounding rocks can be enhanced.
