Drag reduction method of thixotropic slurry
The invention discloses a drag reduction method of thixotropic slurry, and belongs to the technical field of civil engineering. The method includes the steps: firstly, preparing the thixotropic slurry for drag reduction; secondly, placing stirred thixotropic slurry into a slurry storage tank, forming a grouting hole and connecting a grouting pipeline; thirdly, calculating grouting pressure and selecting a grouting pump; finally, performing grouting. The thixotropic slurry comprises sodium bentonite, carboxymethyl cellulose, sodium carbonate, clean water and an appropriate amount of admixture. Frictional drag of a pipe and soil is decreased by a grouting process, the vertex distance can be increased by 40%-70% after lubrication and drag reduction by the grouting process, drag of a top pipe in work can be effectively reduced, the top pipe with a large caliber and a long distance can continuously extend, and the drag reduction method has the advantages of low cost, easiness in technical implementation and high drag reduction efficiency.
