Description

Technical Field

[0001] This utility model belongs to the field of asphalt concrete processing technology, and in particular relates to an asphalt concrete retaining wall template. Background Technology

[0002] At the top of the dam, the construction of the final layer of asphalt concrete core wall is a crucial step in the entire earth-rock dam seepage prevention system. To ensure the seepage prevention effect, copper waterstops are usually installed in the middle of this core wall. Copper waterstops have good corrosion resistance and flexibility, which can effectively prevent water penetration and improve the overall stability of the dam. To install copper waterstops, the final layer of asphalt concrete core wall is often laid on both sides separately. That is, a retaining wall template is installed in the middle of the foundation trench, and the asphalt concrete core wall on one side of the retaining wall template is laid first. During the compaction of the asphalt concrete core wall on this side, the retaining wall template can prevent the asphalt concrete core wall from spreading to the other side of the retaining wall template. After the asphalt concrete core wall on one side of the retaining wall template is laid and compacted, the copper waterstop needs to be accurately installed at the position of the retaining wall template, and then the asphalt concrete core wall on the other side is laid and compacted.

[0003] Traditional formwork set in the middle of the foundation trench consists of multiple vertical steel plates spliced ​​together, with reinforcing bars between the plates restricting their position. However, this method has poor stability, and the steel plates are prone to tilting when the asphalt concrete core wall is compacted on one side, affecting the laying effect of the asphalt concrete core wall. In view of this, we propose an asphalt concrete retaining wall formwork to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the prior art by providing an asphalt concrete retaining wall template.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: an asphalt concrete retaining wall formwork, comprising at least one formwork body, the formwork body being divided into a first formwork and a second formwork, the first formwork having a limiting groove inside, the second formwork having an extension block rotatably installed on the side near the first formwork extending into the limiting groove, the end of the extension block located inside the first formwork having a limiting slider fixedly installed, a spring fixedly installed between the limiting slider and the inner wall of the limiting groove, a limiting component being provided between the first formwork and the second formwork, and a support component being provided on the back of the formwork body.

[0006] By adopting the above technical solution, the template body can be bent and fixed into a stable L-shaped structure during use, which is used to limit the movement when laying and compacting the asphalt concrete core wall on one side. The horizontal part of the L-shaped baffle directly supports one side of the asphalt concrete core wall, forming a solid lateral support structure. This support structure can effectively resist the horizontal thrust when the asphalt concrete is compacted, so that the template body can better maintain its shape stability and is not prone to tilting or deformation. When the template body is not in use, it can be easily spliced ​​into a compact plate structure, which is convenient for stacking and placing, thereby greatly saving storage space and improving the convenience of transportation and storage.

[0007] Furthermore, there are at least two springs, with the two springs located on opposite sides of the extension block.

[0008] Furthermore, the limiting component includes two first slots, both of which are opened on the side of the second template near the first template. Two inserts extending into the corresponding first slots are fixedly installed on the side of the first template near the second template. Two second slots adapted to the inserts are also opened on the front of the second template.

[0009] By adopting the above technical solution, additional connection stability and positioning accuracy can be provided during the folding and assembly of the template body.

[0010] Furthermore, the two first slots are located on both sides of the extension block.

[0011] By adopting the above technical solution, the relative positional relationship between the limiting component and the extension block is ensured, thereby enhancing the stability of the overall structure of the template body.

[0012] Furthermore, the support assembly includes a mounting groove formed on the back of the template body, a U-shaped fixing frame rotatably mounted on the inner wall of the mounting groove, and a positioning element fixedly mounted at the end of the fixing frame.

[0013] By adopting the above technical solutions, the stability and support capacity of the template body has been further improved.

[0014] Furthermore, a connecting groove is provided on one side of both the first template and the second template.

[0015] By adopting the above technical solution, it is convenient to splice multiple template bodies.

[0016] Furthermore, both the first template and the second template have slots on their back sides, and the slots are arranged opposite to the connecting slots.

[0017] Furthermore, a connecting block is rotatably mounted on the inner wall of the slot, and the size of the connecting block is adapted to the size of the connecting slot.

[0018] By adopting the above technical solution, multiple template bodies can be spliced ​​together to form a more stable whole.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. When in use, the formwork body can be bent and fixed into a stable L-shaped structure to limit the movement of the asphalt concrete core wall during laying and compaction. The transverse part of the formwork body directly supports one side of the asphalt concrete core wall, forming a solid lateral support structure. This support structure can effectively resist the horizontal thrust when the asphalt concrete is compacted, thus allowing the formwork body to maintain its shape stability and preventing tilting or deformation. When not in use, the formwork body can be easily spliced ​​into a compact plate structure, which is convenient for stacking and placement, thereby greatly saving storage space and improving the convenience of transportation and storage.

[0021] 2. The retaining wall formwork uses a fixed frame and positioning components. The positioning components can be directly inserted into the soil layer inside the foundation trench, which can effectively position the formwork body and provide additional support when the formwork body is folded into an L-shape, making it more stable after installation.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the specific solution of the embodiment is as follows: An asphalt concrete retaining wall template includes at least one template body 1. The template body 1 is divided into a first template 101 and a second template 102. A limiting groove 4 is opened inside the first template 101. An extension block 3 extending into the limiting groove 4 is rotatably installed on the side of the second template 102 near the first template 101. A limiting slider 5 is fixedly installed at one end of the extension block 3 inside the first template 101. A spring 6 is fixedly installed between the limiting slider 5 and the inner wall of the limiting groove 4. A limiting component is also provided between the first template 101 and the second template 102. A support component is also provided on the back of the template body 1.

[0033] Please refer to Figure 7 When in use, the template body 1 can be bent and fixed into a stable L-shaped structure to limit the movement of the asphalt concrete core wall on one side during laying and compaction. The transverse part of the template body 1 is directly supported on one side of the asphalt concrete core wall, forming a solid lateral support structure. This support structure can effectively resist the horizontal thrust when the asphalt concrete is compacted, enabling the template body 1 to maintain its shape stability and preventing tilting or deformation.

[0034] Additionally, please see Figure 1When the template body 1 is not in use, it can be easily spliced ​​into a compact plate structure, which is convenient for stacking and placing, thereby greatly saving storage space and improving the convenience of transportation and storage.

[0035] It is worth noting that there are at least two springs 6, with the two springs 6 located on both sides of the extension block 3.

[0036] Please see Figure 1 and Figure 5 In this embodiment, the limiting component includes two first slots 8, both of which are opened on the side of the second template 102 near the first template 101. Two inserts 7 extending into the corresponding first slots 8 are fixedly installed on the side of the first template 101 near the second template 102. Two second slots 9 adapted to the inserts 7 are also opened on the front side of the second template 102.

[0037] Among them, the two first slots 8 are located on both sides of the extension block 3.

[0038] In addition, when the insert 7 is inserted into the first slot 8, the template body 1 is a compact plate; and when the insert 7 is inserted into the second slot 9, the side of the first template 101 near the second template 102 is tightly fitted with the upper surface of the second template 102, and the template body 1 is bent and fixed into a stable L-shaped structure.

[0039] In this embodiment, the support component includes a mounting groove 10 formed on the back of the template body 1, a U-shaped fixing frame 11 is rotatably mounted on the inner wall of the mounting groove 10, and a positioning member 2 is fixedly mounted at the end of the fixing frame 11.

[0040] The positioning component 2 can be either a nail or a positioning pin. It can be inserted into the soil layer inside the foundation trench to position the template body 1. It can also provide additional support when the template body 1 is folded into an L-shape, making it more stable after installation.

[0041] Please see Figure 6 In this embodiment, a connecting groove 14 is provided on one side of the first template 101 and the second template 102, and a slot 12 is provided on the back of the first template 101 and the second template 102. The slot 12 and the connecting groove 14 are arranged opposite to each other. A connecting block 13 is rotatably installed on the inner wall of the slot 12. The size of the connecting block 13 is adapted to the size of the connecting groove 14.

[0042] By rotating the connecting block 13 to deflect it to the outside of the first template 101 and inserting it into the corresponding connecting groove 14 on the side of another template body 1, the connection of multiple template bodies 1 can be completed, thereby forming a more stable whole.

[0043] The working principle of the above embodiment is as follows: the first template 101 is pulled away from the second template 102. At this time, the limiting slider 5 slides in the limiting groove 4, and the spring 6 is compressed. At the same time, when the first template 101 moves away from the second template 102, the insert 7 will disengage from the first slot 8. After the insert 7 completely disengages from the first slot 8, the first template 101 is rotated so that the first template 101 is above the second template 102, that is, an L-shape is formed. At this time, the first template 101 is released, and the first template 101 will be reset under the elastic force of the spring 6, so that the first template 101 moves closer to the second template 102. When the insert 7 is inserted into the interior of the second slot 9, the side of the first template 101 close to the second template 102 is tightly attached to the upper surface of the second template 102. The template body 1 is bent and fixed into a stable L-shaped structure. The fixing frame 11 is rotated so that the positioning member 2 extends out, and then the positioning member 2 is inserted into the soil layer inside the foundation trench, thereby completing the positioning of the template body 1.

[0044] Rotate the connecting block 13 to deflect it to the outside of the first template 101, and insert it into the corresponding connecting groove 14 on the side of another template body 1 to complete the connection of multiple template bodies 1, thereby forming a more stable whole.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
