Description

Technical Field

[0001] The utility model belongs to the technical field of counterfort retaining walls, and particularly relates to a splicing retaining wall structure based on recycled concrete. Background Art

[0002] Recycled concrete is a building material made by recycling waste concrete. Due to its important environmental protection and economic value, it is widely used in foundations and retaining wall structures. A counterfort retaining wall refers to a support composed of a vertical plate, a bottom plate, counterforts, and backfill soil behind the wall. It relies on the self-weight of the wall and the weight of the soil filled above the bottom plate of the wall to maintain the stability of the retaining wall.

[0003] At present, the counterfort retaining wall is generally formed into an integral structure by casting after formwork erection, resulting in a long construction period. In the prior art, for example, a Chinese patent with the publication number CN221422034U discloses a precast counterfort retaining wall, which realizes the splicing of counterforts, bottom plates, and vertical plates through a connecting component. Since the connecting component adopts a structure in which a T-shaped connecting groove and a connecting plate cooperate with each other for connection, during the pre-installation process of the vertical plate, it is necessary to push the vertical plate horizontally to insert the connecting plate into the connecting groove. There will be resistance to friction during this process, increasing the construction difficulty. Moreover, after the vertical plate and the bottom plate are spliced, only the T-shaped connecting plate and the connecting groove are used to cooperate to prevent the vertical plate from toppling, resulting in poor pre-installation stability of the vertical plate. Similarly, when inserting the mounting plate into the mounting groove through the counterfort, during the process of making the bottom of the counterfort contact the top of the bottom plate, it is necessary to ensure that the vertical plate is in a completely vertical state, otherwise it will cause difficulty in sliding the mounting plate.

[0004] Therefore, it is necessary to propose a splicing retaining wall structure based on recycled concrete to solve the above problems. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a splicing retaining wall structure based on recycled concrete, which is used to solve the problems of difficult assembly of precast counterfort retaining walls and poor stability after pre-installation in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model provides a splicing retaining wall structure based on recycled concrete, which includes a bottom plate and a retaining wall vertically perpendicular to the bottom plate. A counterfort is fixedly installed between the retaining wall and the bottom plate. The bottom plate, the retaining wall, and the counterfort are all prefabricated. The bottom plate is provided with a first rectangular groove for cooperating with the bottom of the retaining wall and a second rectangular groove for cooperating with the bottom wall of the counterfort. Through holes vertically penetrating the bottom plate are arranged in both the first rectangular groove and the second rectangular groove. Fixing columns for inserting into the ground are installed in the through holes. Connecting holes corresponding to the fixing columns one by one are arranged on the counterfort and the retaining wall, and the fixing columns extend into the connecting holes.

[0008] Further, a third rectangular groove adapted to the side wall of the counterfort is provided on the side wall of the retaining wall.

[0009] Further, the third rectangular groove and the connection hole on the retaining wall are arranged in a staggered manner along the length direction of the retaining wall.

[0010] Further, at least two connection holes are provided on the counterfort along the width direction of the retaining wall, and the height of the fixing column extending into the connection holes on the counterfort increases successively along the direction of the retaining wall.

[0011] Further, a limiting ring is fixedly arranged on the fixing column, and the diameter of the limiting ring is larger than the diameter of the through hole.

[0012] Further, the fixing column is a threaded column, and the outer diameter of the fixing column is smaller than the diameter of the connection hole.

[0013] Further, the limiting ring is threadedly connected to the fixing column.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present utility model hoists the counterfort and the retaining wall onto the bottom plate in a manner of cooperation between the connection hole and the fixing column, reduces the assembly difficulty, and ensures the stability after the retaining wall and the counterfort are pre-installed on the bottom plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] As Figures 1-2As shown in the figure, the present utility model provides a spliced retaining wall structure based on recycled concrete, including: a bottom plate 1 and a retaining wall 2 vertically arranged perpendicular to the bottom plate 1. A buttress 3 is fixedly installed between the retaining wall 2 and the bottom plate 1. Among them, the buttress 3 is a right triangle, and the fitting method of the buttress 3 installed between the retaining wall 2 and the bottom plate 1 is a well-known technical means for those skilled in the art and will not be elaborated here; the bottom plate 1, the retaining wall 2 and the buttress 3 are all prefabricated. A first rectangular groove 101 for fitting with the bottom of the retaining wall 2 and a second rectangular groove 102 for fitting with the bottom wall of the buttress 3 are provided on the bottom plate 1. A third rectangular groove 201 for fitting with the side wall of the buttress 3 is provided on the side wall of the retaining wall 2. Through holes 103 vertically penetrating the bottom plate 1 are provided in both the first rectangular groove 101 and the second rectangular groove 102. Fixing columns 4 for inserting into the ground are installed in the through holes 103. Connection holes 5 corresponding to the fixing columns 4 one by one are provided on both the buttress 3 and the retaining wall 2, and the fixing columns 4 extend into the connection holes 5.

[0022] In this solution, when assembling a spliced retaining wall structure based on recycled concrete, first place the bottom plate 1 on the ground, then insert the fixing columns 4 into the corresponding through holes 103, and make the top of the fixing columns 4 extend a preset distance above the bottom plate 1. Then hoist the retaining wall 2 above the bottom plate 1 and slide it onto the first rectangular groove 101 in a manner that the connection holes 5 and the fixing columns 4 cooperate. At this time, the fixing columns 4 extending into the connection holes 5 on the retaining wall 2 can prevent the retaining wall 2 from tipping over. Then slide the buttress 3 along the third rectangular groove 201 and slide it onto the second rectangular groove 102 in a manner that the connection holes 5 and the fixing columns 4 cooperate. At this time, the fixing columns 4 extending into the connection holes 5 on the buttress 3 can prevent the buttress 3 from tipping over; then concrete can be injected into the connection holes 5 to cover the fixing columns 4.

[0023] In this solution, the buttress 3 and the retaining wall 2 are only hoisted onto the bottom plate 1 in a manner that the connection holes 5 and the fixing columns 4 cooperate, which reduces the assembly difficulty and ensures the stability of the retaining wall 2 and the buttress 3 after being pre-installed on the bottom plate 1.

[0024] In an embodiment of the present utility model, the third rectangular groove 201 and the connection holes 5 on the retaining wall 2 are arranged in a staggered manner along the length direction of the retaining wall 2 to prevent the third rectangular groove 201 and the connection holes 5 from being located on the same straight line along the width direction of the retaining wall 2, resulting in a smaller thickness between the third rectangular groove 201 and the connection holes 5, so as to avoid damage to this position of the retaining wall 2 during the assembly process.

[0025] In an embodiment of the present utility model, at least two connection holes 5 are arranged on the buttress 3 along the width direction of the retaining wall 2, and the height of the fixing columns 4 extending into the connection holes 5 on the buttress 3 increases sequentially along the direction close to the retaining wall 2.

[0026] In this solution, two connection holes 5 are provided on the buttress 3. The line connecting the tops of the fixing columns 4 in the two connection holes 5 is consistent with the inclined wall of the buttress 3. By providing two connection holes 5 on the buttress 3 in this solution, the inclination of the buttress 3 during the installation process is avoided, and the stability of the buttress 3 after installation is improved.

[0027] In an embodiment of the present utility model, a limit ring 401 is fixedly provided on the fixing column 4. The diameter of the limit ring 401 is larger than the diameter of the through hole 103. The fixing column 4 is inserted into the ground along the through hole 103 so that the limit ring 401 abuts against the bottom wall of the first rectangular groove 101 or the second rectangular groove 102. Installation grooves 6 are provided on the retaining wall 2 and the buttress 3 that cooperate with the limit ring 401.

[0028] In this solution, by providing the limit ring 401, the height of the fixing column 4 extending into the connection hole 5 is judged. That is, the height of the fixing column 4 above the limit ring 401 is the height of the fixing column 4 extending into the connection hole 5, so as to ensure that the height of the fixing column 4 extending into the connection hole 5 meets the preset height.

[0029] In an embodiment of the present utility model, the fixing column 4 is a threaded column, and the outer diameter of the fixing column 4 is smaller than the diameter of the connection hole 5. This is to facilitate insertion into the ground, and after the base plate 1, the retaining wall 2, and the buttress 3 are assembled and the connection hole 5 is poured, the fixing effect of the fixing column 4 with the retaining wall 2 and the buttress 3 can be strengthened by the thread.

[0030] In an embodiment of the present utility model, the limit ring 401 is threadedly connected to the fixing column 4 to facilitate adjusting the height of the fixing column 4 extending into the connection hole 5.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present utility model.
