Research on Technology of Porous Tube Grouting Reinforcement to the Subsidence of Semi-Filling and Semi-Excavating Subgrade in Shao-Huai Expressway

Abstract:

In this paper, subsidence diseases of the semi-filling and semi-excavating subgrade in Shao-huai expressway are taken as an example. And the causes of disease of subgrade subsidence are analyzed. The pertinent scheme of grouting reinforcement is designed. According to the subgrade subsidence, the grouting technology of vertical and horizontal porous tube is proposed innovatively. The FWD means of non-destructive testing is used to evaluate the effect of grouting. The results of the evaluation show that the technology of grouting reinforcement by porous tube can achieve the good grouting effect and solve the treatment problem of subgrade subsidence effectively.
