Integrally-assembled cantilever-type retaining wall and construction method thereof

Abstract

The invention discloses an integrally-assembled cantilever-type retaining wall and a construction method thereof. A prefabricated reinforced concrete hollow wall plate (1) is adopted as a wall surface plate, and a base of the retaining wall adopts a prefabricated reinforced concrete bottom plate (2) with vertical lap-joint reinforcing steel bars (3). When the prefabricated reinforced concrete hollow wall plate (1) is in assembling, the vertical lap-joint reinforcing steel bars (3) are stretched into holes in the prefabricated reinforced concrete hollow wall plate (1); vertical stressed reinforcing steel bars (9) are inserted into the holes of the prefabricated reinforced concrete hollow wall plate (1) and concrete (7) is poured to form the integrally-assembled cantilever-type retaining wall. The provided construction method of the integrally-assembled cantilever-type retaining wall in the invention includes the following steps in sequence: (a) preparation work; (b) foundation excavation; (c) hoisting; (d) inserting of the reinforcing steel bars and concrete pouring; (e) backfilling.

Description

technical field [0001] The invention relates to an assembled integral cantilever retaining wall structure and a construction method of the retaining wall. Background technique [0002] In roads, railways, and municipal engineering, retaining walls are required for many slope supports. At present, most of the retaining walls in my country use rubble retaining walls and reinforced concrete retaining walls. The rubble retaining wall needs a large amount of rubble to be mined, which destroys the vegetation and is not conducive to environmental protection. Moreover, the rubble retaining wall has high requirements on the bearing capacity of the foundation, the foundation is buried deep, the amount of work is large, and the construction speed is slow. With the increase of labor wages and rubble prices, the cost of rubble retaining walls will become higher and higher. However, various types of retaining walls poured with reinforced concrete at the construction site require a large ...
