Abstract

The invention provides a protection and reinforcement method for a retaining wall structure. The retaining wall structure is located above the tunnel. The retaining wall structure includes a retaining wall foundation and a retaining wall spliced ​​with the retaining wall foundation. The protection and reinforcement method for the retaining wall structure includes: Build a support frame on the wall; form multiple first positioning holes on the section steel; place the section steel with multiple first positioning holes on the support frame, and use the positions of the multiple first positioning holes to place them on the retaining wall one by one. Correspondingly drill a plurality of second positioning holes; correct the relative position between the first positioning hole on the profiled steel and the corresponding second positioning hole; tighten the profiled steel after the expansion bolt passes through the first positioning hole and the second positioning hole It is fixed on the retaining wall; the two sections of section steel at the corner of the retaining wall are welded by steel plates. The technical solution of the present application effectively solves the problem of cracking or subsidence that is easy to occur when the retaining wall settles or rises in the related art.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a protection and reinforcement method for a retaining wall structure. Background technique [0002] The construction of the high-speed railway tunnel needs to pass through the road, and the shield tunneling scheme is adopted for the construction. During the construction, the undisturbed soil layer and groundwater under the existing road will be disturbed, which will destroy the stability of the original soil layer, and easily cause the road or retaining wall to bulge or sink. , subsidence, affecting the normal driving of the vehicle. [0003] There may be silt and fine sand layers near the roof of the tunnel. If there is stagnant water in the upper layer of the above soil layer, it is easy to cause problems such as collapse, sudden water gushing, and sand gushing, which will affect the retaining wall and may cause the retaining wall to subside. [0004] During the construction...
