Modified thixotropic slurry and preparation method thereof
The invention provides a modified thixotropic slurry. The slurry comprises components of, by mass, 100 bentonite, 80 to 110 water, 8 to 15 sodium carbonate, 60 to 100 white plaster, 0.5 to 2 parts of flocculant and 0.2 to 0.4 of emulgator. The invention further provides a preparation method of the modified thixotropic slurry. The modified thixotropic slurry is provided with resistance reduction thixotropy and solidification properties and good consistence and can form outstanding slurry sleeves to produce certain support, and accordingly, the safety and the reliability of the soil mass on the upper portion during jacking of jacking pipes can be guaranteed, and soil mass collapse and road surface sinking are prevented.
