Embodiment 1

[0026] see figure 1 , an assembled integral cantilever retaining wall, comprising a prefabricated concrete hollow wall panel 1 and a prefabricated reinforced concrete bottom slab 2 with vertically lapped reinforcement bars 3 on one side of the prefabricated reinforced concrete bottom slab 2 . When assembling the prefabricated concrete hollow wall panel 1, the vertical lap steel bars 3 of the prefabricated reinforced concrete bottom slab 2 are extended into the holes in the prefabricated concrete hollow wall panel 1, and the vertical receiving bars are inserted into the holes of the prefabricated concrete hollow wall panel 1 Reinforcing reinforcement and pouring concrete to form an assembled integral cantilever retaining wall.

[0027] see figure 2 , if the prefabricated reinforced concrete base plate 2 has a groove 6, then the prefabricated concrete hollow wall panel 1 must be stuck in the groove 6.

Embodiment 2

[0035] see Figure 7 , is also an assembled integral cantilever retaining wall, but the wall panel adopts the form of variable cross-section, and the prefabricated concrete hollow wall panel 1 is used to build staggered holes to form two wall panels with different heights. Connect them with U-shaped ribs 12 (see Figure 8 ), the interlayer between the two wall panels is filled with concrete 11 to form variable section wall panels.

[0036] Construction of the above-mentioned assembled integral cantilever retaining wall (variable section wall panel):

[0037] (a) Preparatory work: including the prefabrication preparation work of the concrete hollow wall panel 1 and the reinforced concrete floor 2 and the preparation work on the construction site. The prefabrication preparation work is carried out in the prefabrication factory. According to the design drawings, the concrete hollow wall panel 1 and the reinforced concrete bottom slab 2 with vertically lapped reinforcement bars ...

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 ...
