Problems solved by technology

Now the shield machine industry generally uses cement slurry and water glass as the material for back grouting and secondary grouting of the shield machine. These two materials can effectively fill the gap above the segment, but they cannot be used for filling. The gap above the shield body, because the shield machine will be stuck after the cement slurry solidifies, and no further construction can be continued
Therefore, there is no way to fill the void above the shield body, and the problem of ground subsidence has been unavoidable

Abstract

The invention discloses a Kenixiao material. A material A is a base material comprising the following substances in percentage by mass: 95.5% of modified inorganic calcium carbonate, and 4.5% of calcium cellulose; and a material B is an auxiliary material comprising the following substances in percentage by mass: 5% of a plasticizer, 1.5% of a thickener, 10% of a penetrant, 10% of a waterproof agent, 3% of a stabilizer, and 70.5% of water. A use method of the Kenixiao material comprises the steps of: mixing the material A with water, preparing the material B, mixing all the materials, performing injection, and performing cleaning. The Kenixiao material disclosed by the invention has the characteristics of high water tightness, rapid molding, capabilities of never being solidified and becoming viscous quickly. By utilization of an original grouting pump on a shield tunneling machine, the Kenixiao material disclosed by the invention is injected to the periphery of a shield body by virtue of an advanced grouting hole to fill up gaps above the shield body, so that accidents of land subsidence and the like during construction of the shield tunneling machine can be effectively avoided, then the capability of preventing potential safety hazards is improved, and personnel casualties and property losses are reduced.

Description

technical field [0001] The invention relates to a building material, and in particular provides a novel mud-restraining material and a using method. Background technique [0002] At present, all shield tunneling methods will encounter an unavoidable problem that is ground subsidence. The large amount of ground subsidence will cause accidents such as ground subsidence, building collapse, and underground pipeline rupture. Since the diameter of the cutter head of the shield machine is larger than the diameter of the shield body, the diameter of the hole formed after the cutter head is excavated is larger than the diameter of the shield body, and a hole is conveniently formed on the shield body. If the void is not filled in time, ground subsidence will occur. Now the shield machine industry generally uses cement slurry and water glass as the material for back grouting and secondary grouting of the shield machine. These two materials can effectively fill the gap above the segme...
