Retaining wall reinforcing device and method for narrow riverway

Abstract

The invention relates to a retaining wall reinforcing device and method for a narrow riverway. The retaining wall reinforcing device comprises a plurality of U-shaped inverted portals which are arranged at intervals along the riverway. The bottoms of the U-shaped inverted portals are as high as the bottom elevation of a riverbed. Each U-shaped inverted portal is provided with reinforcing walls along the two sides. The reinforcing method comprises the steps that S1, H-shaped steel bottom beams and H-shaped steel stand columns are blanked, and the multiple U-shaped inverted portals are manufactured; S2, trenches are dug along the riverbed; S3, the U-shaped inverted portals are hoisted to corresponding positions, and the H-shaped steel bottom beams are made to be located in the correspondingtrenches; S4, concrete is poured into all the trenches, so that H-shaped steel bottom beams encapsulated by the concrete are formed, and the top surface of the encapsulating concrete is as the bottomelevation of the riverbed; S5, reinforcing ribs are welded between the adjacent H-shaped steel stand columns; and S6, concrete pouring is completed to form a reinforcing retaining wall to encapsulatethe H-shaped steel stand columns, and drain holes are reserved in the pouring process. The reinforcing method and device have the advantages that the structure is stable and reliable, the service lifeis long, construction is convenient and fast, and flood discharge of the riverway and original landscapes on the river bank are not affected.

Description

technical field [0001] The invention mainly relates to a reinforcement technology for a retaining wall of a narrow river, in particular to a reinforcement device and a reinforcement method for a retaining wall of a narrow river. Background technique [0002] After the river retaining wall has been built and used for several years, affected by the subsidence of the foundation and the original construction quality, it is generally faced with reinforcement problems. In order to ensure the reinforcement effect of the retaining wall, the existing retaining wall reinforcement scheme generally needs to occupy a large area of ​​the river, especially in the river section. In the case of limited width, the flood discharge capacity of the river channel will be greatly reduced after the retaining wall is reinforced, and the flood risk will increase during the flood season, which will easily cause loss of life and property to the people on the river bank. The landscape effect has changed...
