Description

Technical Field

[0001] The present application relates to the field of road construction, and in particular to a load-relief plate type retaining wall. Background Art

[0002] The retaining wall uses its own gravity to maintain the stability of the retaining wall under the action of soil pressure. It is a commonly used retaining wall in my country.

[0003] At present, retaining walls are generally made into simple trapezoids, occupying a large area. For example, a Chinese patent with publication number CN104963356A proposes a retaining wall, which includes a base, a concrete wall body with a right-angled trapezoidal cross section that is integrally cast with the base, and a step is provided between the right-angled trapezoidal concrete wall body and the base. A steel skeleton is provided in the concrete wall, thereby increasing the strength of the concrete wall.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: the retaining wall occupies a large area and has a low land utilization rate. Utility Model Content

[0005] In order to reduce the floor space occupied by the retaining wall and improve land utilization, the present application provides a load-relief plate retaining wall.

[0006] The present application provides a load-relief plate retaining wall, which involves the following technical solutions:

[0007] A load-relief plate retaining wall, comprising:

[0008] The retaining wall body is located on one side of the soil;

[0009] The unloading plate is fixedly connected to the retaining wall body, and is located on a side of the retaining wall body close to the soil body and extends into the soil body.

[0010] By adopting the above technical solution, the provision of the unloading plate reduces the footprint of the retaining wall and improves land utilization rate. One end of the unloading plate is connected to the retaining wall body, and the other end extends into the soil, thereby reducing the soil pressure on the retaining wall body, thereby ensuring the stability of the retaining wall body while reducing the footprint of the retaining wall body. In addition, the retaining wall body occupies a small area, that is, the volume of the retaining wall body becomes smaller, thereby reducing the amount of concrete used in casting the retaining wall body, thereby achieving the purpose of reducing the investment cost of the retaining wall body.

[0011] Optionally, the retaining wall further comprises a support block, which is located at the connection position between the retaining wall body and the unloading plate, and one side of the support block is connected to the retaining wall body, and the other side is connected to the unloading plate.

[0012] By adopting the above technical solution, the provision of the support blocks improves the connection stability between the unloading plate and the retaining wall body.

[0013] Optionally, the support block is located on a side of the unloading plate close to the ground.

[0014] By adopting the above technical solution, the connectivity of the retaining wall body of the unloading plate can be better improved when the support block is located on the side of the unloading plate close to the ground compared to when the support block is located on the side of the unloading plate away from the ground.

[0015] Optionally, the retaining wall further comprises a plurality of unloading columns, each of which has one end fixedly connected to the retaining wall body and the other end extending into the soil, and the unloading columns are located on a side of the unloading plate close to the support block.

[0016] By adopting the above technical solution, the setting of the unloading column further improves the connection stability between the retaining wall and the soil.

[0017] Optionally, one end of the unloading column away from the retaining wall body is configured to be conical.

[0018] By adopting the above technical solution, the conical unloading column makes it easier for workers to connect the retaining wall with the soil.

[0019] Optionally, along a direction perpendicular to the surface of the retaining wall body, the length of the unloading column is smaller than the length of the unloading plate.

[0020] By adopting the above technical solution, the length of the unloading column is shorter than the length of the unloading plate, so that soil is less likely to collapse during excavation.

[0021] Optionally, a plurality of drainage pipes are provided in the retaining wall body, and the plurality of drainage pipes penetrate the retaining wall body.

[0022] By adopting the above technical solution, the setting of the drainage pipe can drain rainwater and other moisture in the soil, which on the one hand reduces the pressure on the retaining wall, and on the other hand makes it difficult for rainwater to remain in the soil and erode the soil.

[0023] Optionally, a drainage board is fixedly connected to the retaining wall body, and the drainage board is located on the side of the retaining wall body close to the soil. Both ends of the drainage board are connected to the retaining wall to form a accommodating cavity between the drainage board and the retaining wall body, and the accommodating cavity is connected to the drainage pipe, and a plurality of water-permeable holes are opened on the drainage board.

[0024] By adopting the above technical solution, the setting of the drainage board makes it difficult for soil to enter the drainage pipe and affect the normal use of the drainage pipe.

[0025] Optionally, a permeable geotextile is provided on the side wall of the drainage board close to the retaining wall body.

[0026] By adopting the above technical solution, the provision of the permeable geotextile improves the toughness of the drainage board on the one hand, and on the other hand makes it difficult for soil particles to be washed into the drainage board by water, affecting the water-permeable holes of the drainage pipe and the operating stability of the drainage pipe.

[0027] Optionally, both ends of the drain board are fixedly connected with fixing plates, the fixing plates are arranged in an arc shape, and one side of the fixing plate is fixedly connected to the drain board, and the other side extends in a direction away from the drain board.

[0028] By adopting the above technical solution, the setting of the fixing plate improves the connection stability between the drainage plate and the retaining wall body.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The setting of the unloading plate reduces the floor area of ​​the retaining wall and improves the land utilization rate. One end of the unloading plate is connected to the retaining wall body, and the other end extends into the soil, thereby reducing the soil pressure on the retaining wall body, thereby ensuring the stability of the retaining wall body while reducing the floor area of ​​the retaining wall body;

[0031] 2. The setting of drainage pipes makes it difficult for rainwater to accumulate in the soil and erode the soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-2 This application is described in further detail.

[0036] The present application embodiment discloses a load-relief plate retaining wall. Figure 1 The unloading plate type retaining wall includes a retaining wall body 100, an unloading plate 200, a support block 300 and a plurality of unloading columns 400.

[0037] The retaining wall body 100 is located on one side of the soil. The unloading plate 200 is integrally formed with the retaining wall body 100, the unloading plate 200 surface is vertically arranged with the side of the retaining wall body 100, and one side of the unloading plate 200 is fixedly connected to the side of the retaining wall body 100 close to the soil, and the other side extends into the soil.

[0038] The support block 300 has a triangular cross section and is located at the connection position between the retaining wall body 100 and the unloading plate 200, and is located on the side of the unloading plate 200 close to the ground. One side of the support block 300 is fixedly connected to the retaining wall body 100, and the other side is fixedly connected to the unloading plate 200, so that the support block 300 can reduce the stress concentration at the connection position between the unloading plate 200 and the retaining wall, so as to achieve the purpose of improving the connection stability between the unloading plate 200 and the retaining wall body 100.

[0039] The plurality of unloading columns 400 are located on the side of the unloading plate 200 close to the support block 300, and each of the plurality of unloading columns 400 is fixedly connected to the retaining wall body 100 at one end, and the other end extends into the soil to improve the connection stability between the retaining wall body 100 and the soil. In order to facilitate the workers to install the retaining wall, the side of the unloading column 400 away from the retaining wall body 100 is set to be conical.

[0040] At present, the setting of retaining walls generally adopts the method of cast-in-place or prefabrication. However, no matter whether it is cast-in-place or prefabrication, the staff needs to pre-excavate a space on the soil for accommodating the unloading plate 200 and the unloading column 400. In order to prevent the soil from collapsing during the excavation process, the length of the unloading column 400 is less than the length of the unloading plate 200 in the direction perpendicular to the surface of the retaining wall body 100, thereby reducing the hollow space caused by the unloading column 400, and further preventing the soil from collapsing. In addition, when the retaining wall adopts the method of prefabrication, the staff can only excavate the space for accommodating the unloading plate 200, so that when the staff inserts the unloading column 400 into the soil, the soil is compressed, thereby reducing the space for water to remain in the soil between the unloading plate 200 and the unloading column 400, so as to reduce the erosion of the soil by rainwater, etc.

[0041] In order to drain the water in the soil in time, a plurality of drainage pipes 500 are arranged in the retaining wall, and the drainage pipes 500 penetrate the retaining wall body 100. In order to prevent the soil from entering the drainage pipes 500 and affecting the operation of the drainage pipes 500, a drainage board 600 is fixedly connected to the retaining wall body 100. The drainage board 600 is located on the side of the retaining wall body 100 away from the soil. The cross section of the drainage board 600 is arc-shaped, and the axis of the drainage board 600 is located on the side of the drainage board 600 close to the retaining wall body 100, so that both ends of the drainage board 600 are connected to the retaining wall body 100, and a receiving cavity 620 is formed between the drainage board 600 and the retaining wall. A plurality of water-permeable holes 610 are opened on the drainage board 600, and the sides of the plurality of drainage pipes 500 close to the soil are all connected to the receiving cavity 620. When there is water in the soil, the water will penetrate into the receiving cavity 620 from the water-permeable holes 610, and then flow out through the drainage pipe 500.

[0042] In order to prevent the soil in the soil from entering the accommodating cavity 620 along with the water, a permeable geotextile is bonded and fixed to the side wall of the drainage board 600 away from the retaining wall body 100 .

[0043] Reference Figure 1 and Figure 2 In order to realize the connection between the drain pipe 500 and the retaining wall body 100, two connection grooves are opened on the retaining wall body 100, and the two connection grooves are respectively arranged on both sides of the drain plate 600. Both sides of the drain plate 600 are fixedly connected with a fixing plate 630, and the fixing plate 630 is arc-shaped, and the axis of the fixing plate 630 is located on the side of the fixing plate 630 close to the soil. One side of the fixing plate 630 is fixedly connected to the drain plate 600, and the other end extends in a direction away from the drain plate 600. Both fixing plates 630 are buried in the corresponding connection grooves to realize the connection between the drain plate 600 and the retaining wall body 100.

[0044] The implementation principle of the embodiment of the present application is as follows: the staff opens a space on the soil for accommodating the unloading plate 200, and then installs the retaining wall body 100 and the unloading plate 200 in place to realize the retaining wall construction.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
