TECHNICAL FIELD
[0001] The utility model relates to retaining wall technical field especially relates to a novel retaining wall structure. BACKGROUND
[0002] Retaining wall refers to the supporting roadbed fill or the soil body of hillside, prevents the deformation instability of fill or soil body and is the structure widely used in civil engineering, and the retaining wall is generally composed of the base plate of retaining wall bottom and the wall body on the base plate, for example, the cantilever retaining wall, under the condition of excavation, needs to carry out foundation excavation first, then pours the base plate, pours the wall body again, finally carries out the backside soil body backfill of wall back, when the wall back is adjacent to other structures, the foundation excavation will influence the safety of other structures, and it is often necessary to take the temporary protection measures of excavation slope or excavation pit, which greatly improves the engineering cost, and the temporary slope construction safety risk is high. SUMMARY
[0003] In view of the defects and deficiencies existing in the prior art, the utility model provides a novel retaining wall structure to solve the problems of general retaining wall in construction, such as more foundation excavation, temporary protection measures, high engineering cost and construction safety risk.
[0004] The above-mentioned purpose of the utility model is realized by the following technical scheme:
[0005] A novel retaining wall structure, comprising a wall body shaped and standing on the outside of the retained soil body, the bottom of the wall body is without base plate and is buried below the ground at the bottom of the retaining wall, and
[0006] A top plate laid on the upper side of the retained soil body, the outer end of the top plate is connected with the top of the wall body, and
[0007] A plurality of anchor piles arranged at intervals along the extension direction of the retaining wall and anchored into the retained soil body, the top end of the anchor pile is connected with the top plate.
[0008] Preferably, the bottom of the wall body is buried to a depth of not less than 0.5m.
[0009] Preferably, the bottom of the wall body is buried to a depth of not less than 0.5m.
[0010] Preferably, the bottom of the wall body is provided with an enlarged foot expanding outward, and the enlarged foot is flush with the ground at the bottom of the retaining wall.
[0011] Preferably, the inner end of the top plate is constructed with a tooth wall, the tooth wall is embedded into the retained soil body, and the side wall of the tooth wall abuts against the plurality of anchor piles.
[0012] Preferably, the wall body is provided with a plurality of drainage holes, and the inner end of the drainage hole is provided with a filter body.
[0013] Preferably, the wall is constructed by reverse casting, layer by layer from top to bottom.
[0014] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0015] This invention eliminates the need for a base plate at the bottom of the wall, instead installing a top plate at the top. The top plate sits on the ground level (inner side) at the top of the retaining wall. The wall below the top plate is constructed using a reverse method, with layers poured from top to bottom. This construction method is simple and feasible, significantly reducing excavation and filling work. It also reduces the need for excavation for the base plate of commonly used retaining walls (such as cantilever retaining walls), eliminating the need for temporary protective measures and lowering project costs and construction safety risks. The combination of the top plate and anchor piles provides stable anti-sliding force to the retaining wall, ensuring its effective soil retention. This invention features a simple structure, clear stress conditions, convenient construction, low construction safety risks, economical cost, and promising application prospects.
[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0024] like Figure 1 As shown in the exemplary embodiment of this utility model, the novel retaining wall structure includes a wall 102, a top plate 101, and anchor piles 2. The wall 102 is formed and erected on the outside of the retained soil (with the side of the retaining wall facing away from the ground considered the outside, and the opposite side considered the inside). The bottom of the wall 102 is not provided with a base plate and is buried at a certain depth below the ground surface at the bottom of the retaining wall (the outside ground surface). The top plate 101 is laid on the upper side of the retained soil (i.e., the top plate 101 is located on the ground surface inside the retaining wall). The outer end of the top plate 101 is reliably connected to the top of the wall 102 by steel bars anchored in concrete (the wall 102 is located below the outer end of the top plate 101). A plurality of anchor piles 2 are arranged at intervals along the extension direction of the retaining wall and anchored downwards into the retained soil, with their top ends connected to the top plate 101. That is, each anchor pile 2 is located inside the top plate 101, and the pile body is anchored into the foundation soil beneath the top plate 101.
[0025] In some embodiments, the bottom of the wall 102 is buried at a depth of not less than 0.5m into the ground outside the retaining wall to ensure that when the retaining wall is constructed in an environment with water erosion, such as a river embankment, its burial depth meets the requirements of the erosion depth.
[0026] To ensure the anchoring effect of anchor pile 2, its bottom elevation should be lower than the bottom elevation of wall 102.
[0027] In some embodiments, to improve the stability of the wall 102 and the foundation, an enlarged foot 3 can be provided on the outer side of the bottom of the wall 102, and the enlarged foot can be flush with the ground at the bottom of the retaining wall.
[0028] In other embodiments, to improve the anti-sliding force of the top plate 101, a toothed wall 4 can be provided at the inner end of the top plate 101. The toothed wall 4 is embedded downward into the soil being retained and abuts against the aforementioned anchor piles 2 through its sidewall. The toothed wall 4 can be integrally cast with the top plate 101.
[0029] In some other embodiments, in order to reduce the backwater pressure of the retaining wall, a number of drainage holes 5 can be arranged in the wall 102, and a filter body 6 can be installed on the inner end of the drainage holes 5.
[0030] In the above embodiments, the wall 102 can preferably be formed by top-down layer-by-layer casting using a reverse construction method.
[0031] In practice, the construction steps for this new type of retaining wall structure are as follows:
[0032] S1. Level the site where a retaining wall needs to be set up, lay out the lines and position the anchor piles 2 at intervals, and then pour the top slab 101. The top of the anchor piles is embedded in the concrete of the top slab.
[0033] S2. Excavate the soil outside the retaining wall layer by layer (generally about 0.5m can be used), and pour the wall 102 from top to bottom in layers using the reverse construction method; when pouring each layer of the wall, drainage holes 5 and filter bodies 6 can be buried as needed.
[0034] S3. After pouring to the design elevation of the bottom of the wall 102, excavate and level the ground outside the retaining wall.
[0035] For any other points not mentioned, please refer to existing technology.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be covered within the protection scope of the present utility model.
