Laboratory Test of Influence of Thixotropic Slurry Composition on Drag Reduction Performance
Synchronous grouting is indispensable in the pipe jacking construction process,and the drag reduction performance of thixotropic mud is the key factors influencing the grouting effect of drag reduction.Therefore,this article uses the friction test measure the thixotropic mud and soil mixture of friction parameters,the influence of different component partition ratio on drag reduction performance of the slurry in thixotropic mud was studied.Results show that the three main components of mud——bentonite,the size of the CMC(Carboxylmethyl Cellulose),soda ash content are influential to drag reduction performance of thixotropic mud;The content of bentonite has the greatest influence on the friction parameter of thixotropic mud,the higher the content of bentonite in slurry,the lower the friction coefficient of slurry mixture.
