Reinforcement structure of retaining wall and construction method thereof

Abstract

The invention provides a retaining wall reinforcing structure and a construction method thereof. The problems that existing retaining wall reinforcing structures occupy much land, are poor in stability and affect normal operation are solved. Upwards-inclining drainage holes are formed in a bottommost drainage opening of an existing retaining wall, a drainage pipe with the side wall provided with holes is arranged in the drainage holes, an anchoring hole is formed in the portion, located above the drainage holes, of the existing retaining wall, and a steel channel rib column is arranged at the outer end of the anchoring hole, attached to the outer surface of the existing retaining wall and arranged vertically. An anchoring rod connected with the steel channel rib column penetrates into the anchoring hole. Three grouting pipes are arranged in the anchoring hole and located around the anchoring rod, the inner end of one grouting pipe is tightly attached to the bottom of the anchoring hole, the inner end of another grouting pipe is located on the inner side of a fracture plane, and the inner end of the third grouting pipe is located on the outer side of the fracture plane. Pile foundation channel steel connected with the steel channel rib column is arranged at the bottom end of the steel channel rib column. A protective slope is arranged on the outer side of top filled earth of the existing retaining wall. By means of the retaining wall reinforcing structure and the construction method thereof, the stability of the retaining wall is improved, and the anchoring effect is reliable.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a retaining wall reinforcement structure and a construction method thereof. Background technique [0002] A retaining wall is a wall structure that mainly bears earth pressure and prevents soil from collapsing. The wall can be made of block stones, flakes, and prefabricated concrete blocks as masonry, or it can be poured with flake concrete and reinforced concrete. Retaining walls have been widely used in slope protection projects such as roads, railways, urban construction, water conservancy, mines, and harbors. [0003] During the use of the retaining wall, affected by natural environmental factors such as rain erosion, freeze-thaw damage, and weathering, as well as human factors in the early construction stage, many retaining wall structures have successively experienced wall weathering, wall voids, and external walls. Displacement of expansion joints in drums and walls, exce...
