| Abstract: | The first and second grade slopes of a certain expressway are suffering from erosion,crack,collapse and other diseases.Through the calculation of the design anti-sliding force,The steel flower pipe grouting scheme is adopted to strengthen the slope,Making the steel flower tube and the surrounding soil form a sheet pile structure to ensure that the slope reaches a stable state.And introduce the grouting construction process and related technology of steel flower tube.The grouting process has been tested for relevant indicators.Monitoring of settlement and displacement after reinforcement.The overall effect is good. |
