The commonly used grouting materials are inorganic grouting materials, such as superfine cement or conventional cement and water glass, organic grouting materials, such as foamed polyurethane (aqueous polyurethane or oil polyurethane) or epoxy resin, and the like. The superfine cement grouting material has the advantages of high strength of a hardened body, good bonding strength with peripheral concrete, long service life with the same material as the peripheral concrete structure, easy shrinkage after hardening, uncontrollable setting time and easy dispersion when meeting open water with high water pressure. Although the hardening time of the conventional cement and water glass can be adjusted, the quick setting effect can be achieved in a short time, but a hardened body is easy to shrink, and the self compactness can be influenced. The foaming polyurethane has the advantages of foaming when meeting water, rapidly stopping water and obvious effect, but the foaming body has no strength and can not play a role in reinforcing the structure, and the foaming body has poor cohesiveness with concrete and can shrink more when losing water.
