Abstract

The invention discloses a low-cost thixotropic pasty grout which is prepared by taking clay slurry (prepared from undisturbed soil by using a slurry making machine from clay) as a main raw material and taking general silicate cement, tetracalcium aluminoferrite, calcium sulphoaluminate, gypsum, sodium aluminate, calcium oxides, calcium hydroxides as main cementing materials through the steps of mixing the main raw material with the main cementing materials and stirring the obtained mixture. The thixotropic pasty grout can be used as a controllable grouting material and widely applied to the controllable anti-seepage and leaking-stoppage grouting projects performed in foundations in geotechnical projects such as water conservancy and hydropower projects, mine projects, tunnel projects, underground space projects, and the like, wherein the controllable anti-seepage and leaking-stoppage grouting projects comprise the operations of carrying out anti-seepage and leaking-stoppage grouting and project emergency reinforcement on high-permeability stratums.

Description

Technical field

[0001] The present invention involves water -stop materials, which are specifically formed with a tactile clay paste and its preparation methods. Background technique

[0002] In the water conservancy, hydropower, mining, transportation, underground space and other geotechnical water -based water transmittance floors, as well as the anti -seepage and leakage grouting of the fourth -line strong water -based strata of the engineering emergency reinforcement treatment., Irrill a variety of grouting processes such as mortar or gravel, chemical grouting and other grouting processes for anti -seepage and plugging.Large, the effect of anti -seepage and leakage is poor.

[0003] At present, the method of quick -condensed cement paste or cement water glass dual fluid grouting method is often used for blocking and anti -seepage. The initial shear and yield intensity of the initial shear and cement glass pulp of quick -coagulation cement paste and cement water glass pulp can...
