[0001] The utility model relates to the technical field of retaining wall reinforcement, in particular to a deviation correction and reset structure for an inclined reinforced concrete retaining wall. Background Technique

[0002] Constructing retaining walls is an important means to support and reinforce backfill or hillside soil masses, prevent landslides and maintain project safety, and it is widely used in the field of geotechnical engineering. At the same time, the problem of inclined deformation of the retaining wall due to creep of the backfill soil mass and insufficient foundation resistance of the wall body is relatively common in the fields of slopes, roadbeds and filling projects.

[0038] Embodiment 1

[0039] Referring to Figure 1-2 , a rectification and reset structure for an inclined reinforced concrete retaining wall, comprising

[0040] A foundation pit, which is arranged on the ground 1 on the inclined side of the retaining wall;

[0041] Channel steel 2, which is arranged in the foundation pit;

[0042] Bracket 4, which includes a first support section 42 and a second support section 41 that are hinged to each other, wherein the end of the first support section 42 abuts against the side surface of the retaining wall, and the end of the second support section 41 abuts in the channel steel 2;

[0043] A positioning part, which is fixed at the bottom of the retaining wall;

[0044] A pulling part, one end of which is connected to the positioning part, and the other end of which is connected to the hinge point of the first support section and the second support section in the bracket 4; and

[0045] A bottom reinforcement mechanism, which is used to fix the root of the retaining wall and the ground.

[0046] As a further improvement of the above solution, both the first support section 42 and the second support section 41 are made of stainless steel pipes, and a backing plate 15 is arranged between the end of the first support section 42 and the side surface of the retaining wall.

[0047] As a further improvement of the above solution, the second support section 42 is in a V-shaped structure, and the middle of the second support section 42 is rotatably connected to the first support section by a connecting member 3. One end of the second support section 42 away from the connecting member 3 is supported in the channel steel 2.

Grouting pipes 6 are installed at the grouting holes. The injected cement slurry fills the foundation voids and forms a composite soil body after consolidation, forming a foundation reinforcement area 14 under the foundation of the retaining wall to complete the reinforcement of the retaining wall foundation;
