Experimental Study on Repairing Incomplete Defects of Grout Sleeve Splicing
This article focuses on the repair of the defects of insufficient grouting in the construction of grout sleeve splicing of rebars.It compares the physical properties between specialized grouting repair materials and sleeve grouting materials,and conducts gravity flow filling tests in confined spaces and grouting repair tests on insufficient joints.The results show that the grouting repair materials have obvious advantages in physical properties and constructability,with high fullness of gravity filling in narrow space.The tensile properties of sleeve joints with varying degrees of defects are all qualified after repairing,but the deformation performance is affected by defects caused by leakage of grout,and the larger the defects,the greater the residual deformation.The purpose of this paper or the problem to be solved;the method and process of solving the problem;the main results and conclusions;the innovation and uniqueness of this paper.
