Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to slope support construction, specifically a reinforced steel suspended cast-in-place pile and retaining wall slope support structure. Background Technology

[0002] With the large-scale development of national infrastructure construction, the construction in hilly and mountainous areas of my country has increased, and the construction technology of slope protection has become more demanding, with increasingly higher requirements for safety and aesthetics. The construction method of cast-in-place pile + retaining wall slope protection can not only ensure the safety and stability of the structure, but also meet the requirements of aesthetics.

[0003] However, in actual construction, the construction of cast-in-place piles and retaining walls are two separate processes. After the cast-in-place piles are formed, the slope is excavated, and then the retaining wall is constructed. To ensure that the two can be better integrated, the traditional practice is to install rebar on the cast-in-place piles. Although this can meet the construction requirements, the rebar installation process causes significant damage to the cast-in-place piles, and there is a risk of conflict between the rebar and the reinforcing steel bars in the piles during drilling. It also requires more manpower and has a longer construction period, which is not conducive to the construction of slope protection projects. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to provide a reinforced suspended cast-in-place pile and retaining wall slope support structure.

[0005] This utility model is achieved through the following technical solution:

[0006] A reinforced suspended cast-in-place pile and retaining wall slope protection structure includes cast-in-place piles, a retaining wall, and steel hooks connecting the cast-in-place piles and the retaining wall.

[0007] A cast-in-place pile includes a pile body, which contains reinforcing bars, a concrete cover support, and embedded metal sleeves. The concrete cover support is welded and fixed to the reinforcing bars, and the embedded metal sleeves are welded and fixed to the concrete cover support.

[0008] The retaining wall includes the retaining wall body, and the retaining wall body is reinforced with steel bars.

[0009] The rebar hook adopts a Z-shaped rebar hook, which includes a horizontal rebar segment. One end of the horizontal rebar segment is bent to form a downwardly extending lower vertical rebar segment, and the other end of the horizontal rebar segment is bent to form an upwardly extending upper vertical rebar segment. The lower vertical rebar segment of the rebar hook is inserted into the metal sleeve embedded part in the pile body. The horizontal rebar segment of the rebar hook is embedded in the retaining wall and welded and fixed to the rebar of the retaining wall. The upper vertical rebar segment of the rebar hook is clamped on the outer wall surface of the retaining wall.

[0010] Furthermore, several sets of concrete protective layer supports and metal sleeve embedded parts are evenly distributed from top to bottom inside the cast-in-place pile body, and a steel bar hook is inserted into each metal sleeve embedded part.

[0011] Furthermore, the spacing between the concrete protective layer support, metal sleeve embedded parts, and steel bar hooks of the cast-in-place pile is 1.5m from top to bottom.

[0012] Furthermore, the reinforcing steel of the cast-in-place pile includes vertical main bars and circumferential stirrups, and the concrete protective layer support of the cast-in-place pile is welded and fixed to the vertical main bars.

[0013] Furthermore, the retaining wall reinforcement includes horizontal and vertical reinforcement, with the horizontal reinforcement segment of the reinforcement hook abutting below the horizontal reinforcement and welded to the horizontal reinforcement for fixation.

[0014] Furthermore, the outer diameter of the metal sleeve embedded part is 25mm, and the steel bar hook is made of 22mm diameter threaded steel bar.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1) This utility model adopts a suspended structure design with steel bar hooks and metal sleeve embedded parts as the main body, so that the pile body and the retaining wall body form an integral whole and the connection is more solid.

[0017] 2) The suspended structure design of this utility model, which is mainly composed of steel bar hooks and metal sleeve embedded parts, is scientific, ingenious, and easy to install. It does not require rebar installation or large-area damage to the pile body structure, and better ensures construction quality while reducing manual labor and costs.

[0018] 3) The steel bar hook in this utility model not only serves as the main structure of the suspended structure, but also acts as a formwork support rod when the formwork is erected on the retaining wall, effectively protecting the cross-sectional dimensions of the retaining wall and thus having a dual function.

[0019] In summary, this utility model combines cost reduction and efficiency improvement with prefabricated management concepts, changing the traditional methods such as rebar installation which cause significant damage to the overall integrity of the pile body. Instead, it designs a simple-to-operate and convenient-to-construct connected suspended slope support structure, which improves the integrity and construction quality of slope support components and is worthy of promotion and use.
