Description
Technical Field
[0001] This application relates to the field of retaining wall technology, and in particular to a prefabricated retaining wall. Background Technology
[0002] Retaining walls are structures that support roadbed fill or hillside soil and prevent deformation and instability of the fill or soil. However, cast-in-place retaining walls have some drawbacks. For example, the long curing time of cast-in-place concrete leads to low construction efficiency. Furthermore, traditional cast-in-place concrete retaining walls are difficult to implement in areas where pumps or wheelbarrows cannot reach, which limits the applicability of retaining walls to some extent. Utility Model Content
[0003] To improve the construction efficiency and expand the applicability of retaining walls, this application provides a prefabricated retaining wall.
[0004] The prefabricated retaining wall provided in this application adopts the following technical solution: A prefabricated retaining wall includes prefabricated blocks, each prefabricated block being rectangular in shape. The splicing surfaces of the prefabricated blocks are provided with connectors, each connector including a connecting block and a connecting groove. Multiple connecting blocks are provided and are parallel to each other, and multiple connecting grooves are provided and are parallel to each other. The connecting blocks are inserted into the connecting grooves.
[0005] Optionally, the vertical splicing seams of the prefabricated blocks are staggered with the adjacent vertical splicing seams.
[0006] Optionally, the connector further includes a vertical insert bar, which is used to insert into the prefabricated block after the prefabricated blocks are horizontally spliced, so as to connect the prefabricated blocks of adjacent layers.
[0007] Optionally, the cross-section of the vertical reinforcing bar is I-shaped.
[0008] Optionally, the prefabricated block has a through connection hole from the top to the bottom surface, and the vertical insert is inserted into the connection hole. The number of connection holes on the prefabricated block is greater than 2.
[0009] Optionally, the vertical reinforcing bars are connected to the prefabricated blocks and then inserted and fixed to the ground.
[0010] Optionally, the prefabricated retaining blocks have chamfered corners perpendicular to the protective surface. After adjacent prefabricated retaining walls are spliced together, the adjacent chamfers are combined to form a drainage channel.
[0011] Optionally, the side splicing surface of the prefabricated block is provided with a rubber pad. After adjacent prefabricated blocks are spliced, the rubber pad is compressed to reduce the gap between the prefabricated blocks.
[0012] Optionally, the vertical insert is triangular at the end where it is inserted into the ground.
[0013] Optionally, the end of the vertical insert is provided with a fixing rod, which is used to press against the uppermost prefabricated block.
[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. For areas where commercial concrete and vehicles cannot reach, precast blocks are transferred to the retaining wall construction site. The first layer of precast blocks is then erected on the ground, followed by the second layer. Connecting blocks are inserted into the slots to connect the first and second layers of precast blocks into a whole. This precast block construction process is repeated to complete the retaining wall assembly, thereby improving the efficiency of retaining wall construction. By precasting and using manual transportation, retaining walls can be constructed in areas where commercial concrete cannot reach, improving the applicability of the retaining wall.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0018] This application discloses a prefabricated retaining wall. (Refer to...) Figure 1 , Figure 2 and Figure 3 The prefabricated retaining wall includes a prefabricated retaining block 1, which is rectangular in shape. The splicing surface of the prefabricated retaining block 1 is provided with a connector, which includes a connecting block 2 and a connecting groove 3. Multiple connecting blocks 2 are provided and are parallel to each other, and multiple connecting grooves 3 are provided and are parallel to each other. The connecting blocks 2 are inserted into the connecting grooves 3.
[0019] For areas where commercial concrete is difficult to reach, precast retaining blocks 1 are transferred to the retaining wall construction site. Then, the first layer of precast retaining blocks 1 is erected on the ground, followed by the second layer of precast retaining blocks 1 on top of the first layer. At this time, connecting blocks 2 are inserted into the insertion slots to connect the first and second layers of precast retaining blocks 1 into a whole. The precast retaining block 1 construction process is repeated to complete the construction of the retaining wall, thereby improving the construction efficiency of the retaining wall.
[0020] Reference Figure 3 and Figure 4 To facilitate the transport of prefabricated block 1 to the retaining wall installation site, the single-sided dimension of prefabricated block 1 is less than 50cm, the height is less than 25cm, and the weight of a single block is less than 50kg, so as to facilitate the transport of prefabricated block 1 to the design site.
[0021] Reference Figure 2 To avoid the prefabricated retaining wall forming a continuous vertical joint, which would reduce the load-bearing capacity of the spliced retaining wall, in this embodiment of the application, the vertical splicing joint of the prefabricated retaining block 1 is staggered with the adjacent vertical splicing joint.
[0022] Reference Figure 2 and Figure 5 To further improve the overall strength of the retaining wall, the connector also includes vertical inserts 4. The vertical inserts 4 are used to insert into the precast blocks 1 after the precast blocks 1 are spliced horizontally, so as to connect the precast blocks 1 of adjacent layers. After the retaining wall is built in the horizontal and vertical directions, the vertical inserts 4 are inserted into the precast blocks 1, thereby connecting the precast blocks 1 into a whole, thus improving the overall strength of the retaining wall.
[0023] Reference Figure 2 and Figure 5 In this embodiment, the retaining wall is erected next to the railway. Since there are many scrap steel rails next to the railway, and it is troublesome to transport the scrap steel rails out, the vertical reinforcing bars 4 are made of scrap steel rails with an I-shaped cross-section to facilitate the reuse of scrap steel rails. The steel rails have good physical and chemical properties and have a good fixing effect on the prefabricated retaining blocks 1 when connected, thereby improving the overall strength of the retaining wall.
[0024] Reference Figure 2 and Figure 5 In this embodiment of the application, a through connecting hole 5 is provided from the top surface to the bottom surface of the prefabricated block 1, and the vertical insert 4 is inserted into the connecting hole 5. The number of connecting holes 5 on the prefabricated block 1 is greater than 2. The number of connecting holes 5 on the prefabricated block 1 is greater than 2, which makes it easier to fix a single prefabricated block 1 with multiple vertical insert 4, thereby improving the fixing effect of the prefabricated block 1 and reducing the possibility of the prefabricated block 1 shifting.
[0025] Reference Figure 2 and Figure 5To further improve the stability of the retaining wall, the vertical reinforcing bars 4 are connected to the precast blocks 1 and then inserted and fixed to the ground; the vertical reinforcing bars 4 are inserted deep into the ground after being connected to the precast blocks 1, thereby improving the stability of the retaining wall.
[0026] Reference Figure 2 and Figure 5 In this embodiment of the application, the corners of the prefabricated retaining block 1 perpendicular to the protective surface are chamfered. After the adjacent prefabricated retaining walls are spliced together, the adjacent chamfers are combined to form a drainage channel 6. The chamfering of the corners of the prefabricated retaining block 1 improves the safety of transporting the prefabricated retaining block 1. And after the adjacent prefabricated retaining blocks 1 are spliced together to form a drainage channel 6, it is convenient to drain the rainwater that seeps behind the retaining wall.
[0027] Reference Figure 2 and Figure 5 Furthermore, in this embodiment of the application, a rubber pad is provided on the side splicing surface of the prefabricated retaining block 1. After the adjacent prefabricated retaining blocks 1 are spliced, the rubber pad is compressed to reduce the gap between the prefabricated retaining blocks 1. After the rubber pad is installed, the gap between the adjacent prefabricated retaining blocks 1 is sealed, thereby reducing the possibility of rainwater carrying mud and sand into the adjacent prefabricated retaining blocks 1 and improving the stability of the retaining wall.
[0028] Reference Figure 2 and Figure 5 In order to facilitate the compression of the rubber pad by the precast block 1 and reduce the gap between adjacent precast blocks 1, the vertical insert 4 is triangular at the end where it is inserted into the ground; as the vertical insert 4 enters the precast block 1 through the connecting hole 5, the vertical insert 4 drives the precast block 1 to move and compress the rubber pad.
[0029] Reference Figure 2 and Figure 5 To reduce the gap between the horizontal splicing surfaces of the precast blocks 1, the ends of the vertical reinforcing bars 4 are provided with fixing rods 7, which are used to press against the uppermost precast blocks 1. When the vertical reinforcing bars 4 are driven into the ground, the fixing rods 7 press against the uppermost precast blocks 1, thereby reducing the gap between the precast blocks 1.
[0030] The implementation principle of a prefabricated retaining wall according to an embodiment of this application is as follows: For areas where commercial concrete is difficult to reach, precast retaining blocks 1 are transferred to the retaining wall construction site. Then, the first layer of precast retaining blocks 1 is erected on the ground, followed by the second layer of precast retaining blocks 1 on top of the first layer. At this time, connecting blocks 2 are inserted into the insertion slots to connect the first and second layers of precast retaining blocks 1 into a whole. The precast retaining block 1 construction process is repeated to complete the construction of the retaining wall, thereby improving the construction efficiency of the retaining wall.
[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
