Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a cast-in-place reinforced earth retaining plate reinforcement structure. Background Art

[0002] With the development of my country's construction industry, the scale of housing construction projects is getting larger and larger, and the environment around the foundation pit is becoming more and more complex. In order to prevent the collapse of trenches and foundation pit earth during foundation pit construction, which may threaten the life safety of project construction workers, the establishment of retaining wall reinforcement structure plays a key role in ensuring the safety and stability of foundation pit construction.

[0003] At present, in the traditional retaining wall construction, considering the construction cost and the construction deployment of the retaining wall pile foundation, retaining plates are generally not set up. Usually, only reinforced concrete cast-in-place retaining walls are used for foundation pit protection in engineering projects. With the increasing complexity of the foundation pit of the construction project, the original retaining wall construction cannot meet the requirements of construction safety, and cracks in the supporting piles are prone to occur and expand, which cannot effectively play the role of retaining soil and has low retaining efficiency.

[0004] To solve the above problems, Chinese patent application number 201921151757.5 discloses a high fill slope retaining structure, the retaining structure disclosed above includes air-side support piles, retaining side support piles and retaining plates forming a pile-sheet-wall combination structure, and cross beams and inclined beams connecting the two support piles; the inclination direction of the inclined beam is downward from the retaining side to the air-side, the cross beams and the inclined beams are arranged at intervals and the plane formed by the two is perpendicular to the pile-sheet-wall combination structure; the tops of the two support piles are provided with their own crown beams, and the two adjacent air-side support piles are connected by a connecting beam. Chinese patent application number 201711238710.8 discloses a method for constructing a composite retaining wall on a mountain slope based on gravity and geogrid reinforcement. The composite retaining wall construction method disclosed above includes the following steps: A. Anti-slip pile construction: Anti-slip piles are evenly arranged along the pre-positioned wall foot positioning line; B. Retaining board installation: The retaining board is installed on the inner side of the anti-slip pile to block the gap between adjacent anti-slip piles; C. Leveling and filling the foundation: First, the joint part of the foundation and the original slope is excavated into a step shape; secondly, the foundation soil within the geogrid paving range is cleaned; finally, the foundation is treated with reinforced soil replacement; D. Geogrid laying; E. Step D is repeated until the retaining wall structure is designed at the elevation.

[0005] In the above-mentioned prior art disclosed, collapsed earth is blocked by setting retaining plates and retaining side support piles, and the structural strength of the retaining plates and retaining side support piles is increased by means of cross beams and inclined beams. Although the above scheme can block the earth, when there is too much collapsed earth, the impact of the earth on the retaining plates is likely to cause cracks in the retaining plates, or even break and collapse. At the same time, as time goes by, cracks will also appear on the retaining plates, which will increase the risk of collapse of the retaining plates, which is prone to danger and may cause personal injury.

[0011] As a preferred solution of the utility model, the ends of the two reinforcing ribs located on the same horizontal line overlap each other, and a welding section for fastening the two reinforcing ribs is formed at the overlapping portion.

[0012] As a preferred solution of the utility model, a construction space for filling is formed in the retaining wall structure.

[0013] As a preferred solution of the utility model, the retaining wall structure is a solid wall structure, and the construction space is cast to form the solid wall structure.
