[0001] This utility model relates to the field of waterway engineering technology, and in particular to a permeable dam prefabrication mold and a permeable dam component made using the permeable dam prefabrication mold. Background Technology

[0002] A permeable dam is a lightweight guiding structure that allows some water to flow through the dam body, thereby lowering the phreatic line and improving the stability of the dam body.

[0003] Most existing permeable dams are constructed by piling up natural materials such as gravel and pebbles to form the dam body and foundation. Some permeable dams are also planted with plants that purify the water. However, because traditional permeable dams require dumping materials for construction, the construction period is long and there are significant safety hazards in water construction, resulting in low construction efficiency and hindering the safety of construction workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated mold for permeable dams and permeable dam components made using the prefabricated mold, which solves the problems of low construction efficiency and lack of safety for construction workers in existing technologies.

[0005] According to an embodiment of this utility model, a precast mold for a permeable dam includes an outer mold, a crossbar, and an inner mold. The outer mold includes two parallel vertical plates, each with an aligned first slot, and the two ends of the crossbar extend into the first slot. Two side plates are provided between the two vertical plates, symmetrically arranged, and each with an aligned second slot. The inner mold is located within a trapezoidal area enclosed by the two vertical plates and the two side plates, and there is a gap between the inner mold and the outer mold. The inner mold includes a support plate, with first connecting frames at both ends. The crossbar abuts against the support plate, and the opposite sides of the support plate are fixedly connected to the two vertical plates. The first connecting frames are fixedly connected to the edges of the first slots. The inner mold also includes blocks on both sides of the support plate and second connecting frames connecting the support plate and the blocks. The second connecting frames are fixedly connected to the edges of the second slots. The inner mold also includes a top plate parallel to the support plate, which is fixedly connected to the outer mold.

[0006] Furthermore, the vertical plate is provided with a first through hole, and the side plate is provided with a second through hole aligned with the first through hole.

[0007] Furthermore, the vertical plate is provided with a third through hole and the third through hole is located near the edge of the first slot, and the support plate is provided with a fourth through hole aligned with the third through hole.

[0008] Furthermore, the number of crossbars is at least two, and the crossbars are arranged in parallel and in a row within the first slot.

[0009] Furthermore, the first connecting frame includes a first connecting block, a second connecting block, and a third connecting block connected in sequence, wherein the first connecting block and the third connecting block are respectively attached to two sides of the edge of the first slot.

[0010] Furthermore, the top plate is provided with clearance openings on opposite sides, and the clearance openings are connected to the gaps between the outer mold and the inner mold.

[0011] Furthermore, a fourth connecting block is provided in each of the clearance openings, and the fourth connecting block is fixedly connected to the top plate and the side plate respectively.

[0012] On the other hand, according to an embodiment of the present invention, a permeable dam component is also provided, which is made using the above-mentioned permeable dam prefabrication mold, including a parallel bottom plate and a top plate.

[0013] Furthermore, two lifting rings are spaced apart on the inclined side, and the two lifting rings are respectively located on opposite sides of the second opening.

[0014] Compared with existing technologies, this utility model has the following advantages: By using an outer mold to form a trapezoidal space to accommodate the inner mold, and setting a crossbar in the first slot of the outer mold to support the support plate of the inner mold, and setting a first connecting frame and a stop block on both sides of the support plate, the first connecting frame is fixedly connected to the edge of the first slot to keep the position of the support plate and the stop block stable in the outer mold, and the top plate of the inner mold is installed on the outer mold through a second connecting frame and a second slot fixedly connected.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figures 1 to 4 As shown in the figure, Embodiment 1 of this utility model proposes a prefabricated mold for permeable dams, which is used to prepare permeable dam components. The permeable dam components can be placed in water to quickly build a permeable dam.

[0024] like Figure 1As shown, the precast mold for the permeable dam includes an outer mold 100, a crossbar 200, and an inner mold 300. The outer mold 100 includes two parallel vertical plates 101, each with aligned first slots 102, and the two ends of the crossbar 200 extend into the first slots 102. Two side plates 103 are provided between the two vertical plates 101 and are fixedly connected to the vertical plates 101. The two side plates 103 are symmetrically arranged, and the two vertical plates 101 and the two side plates 103 form a trapezoidal area. Aligned second slots 104 are provided on the two side plates 103. The inner mold 300 is located within the area enclosed by the two vertical plates 101 and the two side plates 103, and there is a gap between the inner mold 300 and the outer mold 100. The inner mold 300 includes a support plate 301, and the two ends of the support plate 301 are respectively provided with first connecting frames 30. 3. The crossbar 200 abuts against the support plate 301, and the opposite sides of the support plate 301 are respectively fixedly connected to the two vertical plates 101, so that the position of the support plate 301 in the outer mold 100 remains stable. The first connecting frame 303 is fixedly connected to the edge of the first slot 102. The inner mold 300 also includes a stop block 302 disposed on both sides of the support plate 301 and a second connecting frame 305 connecting the support plate 301 and the stop block 302. The second connecting frame 305 is fixedly connected to the edge of the second slot 104 to fix the top plate 304 on the outer mold 100. The inner mold 300 also includes a top plate 304 parallel to the support plate 301. The top plate 304 is fixedly connected to the outer mold 100. After the inner mold 300 is installed in the outer mold 100, a steel reinforcement cage is placed and concrete is poured to obtain a permeable dam component.

[0025] Specifically, the operation steps for preparing permeable dam components using the permeable dam prefabrication mold provided in this embodiment are as follows: First, combine the side plate 103 with the vertical plate 101 to form a trapezoidal area with the two vertical plates 101 and the two side plates 103. Then, insert the crossbar 200 into the first slot 102. Next, install the first connecting frame 303, the stop block 302, and the second connecting frame 305 onto the support plate 301 respectively. Fix the support plate 301 to the vertical plate 101, the first connecting frame 303 to the edge of the first slot 102, and the second connecting frame 305 to the edge of the second slot 104 so that the positions of the support plate 301 and the stop block 302 within the outer mold 100 remain stable. After the support plate 301 is installed onto the outer mold 100, the crossbar 200 abuts against the support plate 301. Then, the top plate 304 is fixedly connected to the outer mold 100, and the inner mold 300 is installed inside the outer mold 100. At this time, a steel reinforcement skeleton is placed in the gap between the outer mold 100 and the inner mold 300 and concrete is poured to obtain a permeable dam component. The obtained permeable dam component is trapezoidal, and because the inner mold 300 is set inside the outer mold 100, the permeable dam component has a through first opening and a second opening. The permeable dam component can be quickly constructed by putting it into the water. The first opening and the second opening on the permeable dam component can allow water flow, silt, etc. to pass through, or plants can be planted inside the permeable dam component, which effectively improves the construction efficiency of the permeable dam. Moreover, the permeable dam component can be cast on land using the permeable dam prefabrication mold, and the permeable dam component is formed quickly, thereby effectively reducing the construction difficulty and risk. In addition, the permeable dam prefabrication mold has a reliable structure and is easy to install and disassemble.

[0026] Please refer to Figure 2 , Figure 3 and Figure 4 The vertical plate 101 has a first through hole 105, and the side plate 103 has a second through hole 106 aligned with the first through hole 105. By providing the first through hole 105 on the vertical plate 101 and the second through hole 106 aligned with the first through hole 105 on the side plate 103, the vertical plate 101 and the side plate 103 can be assembled into a single unit by passing bolts through the first through hole 105 and the second through hole 106 in sequence and tightening them with nuts. This facilitates the assembly of the permeable dam prefabrication mold while ensuring a reliable connection between the vertical plate 101 and the side plate 103.

[0027] In detail, the vertical plate 101 is provided with a third through hole 107, which is located near the edge of the first slot 102. The support plate 301 is provided with a fourth through hole 306 aligned with the third through hole 107. When the support plate 301 is installed onto the outer mold 100, bolts are passed through the third through hole 107 and the fourth through hole 306 in sequence, and nuts are used to lock the support plate 301 onto the vertical plate 101 and keep it at the edge of the first slot 102, ensuring that a through first opening is formed on the cast-in-place permeable dam component.

[0028] As shown in the figure, there are at least two crossbars 200, and the crossbars 200 are arranged in parallel and in a row within the first slot 102. By setting multiple crossbars 200 within the first slot 102 to abut against and support the support plate 301, the stability of the support plate 301 on the outer mold 100 is further improved, preventing deformation of the support plate 301 under the pressure of concrete during the pouring process, so that the shape of the resulting permeable dam component is consistent with the preset shape.

[0029] like Figure 1 As shown, in this embodiment, the first connecting frame 303 includes a first connecting block 307, a second connecting block 308, and a third connecting block 309 connected in sequence. The first connecting block 307 and the third connecting block 309 are respectively attached to two of the edges of the first slot 102. The first connecting block 307, the second connecting block 308, and the third connecting block 309 are sequentially connected by threaded connectors to combine the first connecting block 307, the second connecting block 308, and the third connecting block 309, ensuring the overall structural stability of the first connecting block 307. The first connecting block 307 is also connected to the vertical plate 101 and the support plate 301 by threaded connectors, thereby ensuring the structural stability of the permeable dam precast mold. After the first connecting frame 303 is connected to the vertical plate 101, the first connecting block 307 and the third connecting block 309 respectively fit against two edges of the first slot 102, so that the first connecting frame 303 and the vertical plate 101 fit tightly, preventing concrete from overflowing from the gap between the first connecting frame 303 and the vertical plate 101 during the pouring process.

[0030] Please refer to Figure 1The top plate 304 has clearance openings 310 on opposite sides, which are connected to the outer mold 100 and the inner mold 300. The clearance openings 310 on both sides of the top plate 304 are used to pour concrete into the precast mold of the permeable dam, facilitating the casting of the permeable dam components.

[0031] Specifically, in this embodiment, a fourth connecting block 311 is provided in each of the clearance openings 310, and the fourth connecting block 311 is fixedly connected to the top plate 304 and the side plate 103 respectively. Using the fourth connecting block 311 to connect the top plate 304 and the side plate 103 can improve the strength of the connection between the top plate 304 and the outer mold 100, preventing the concrete from colliding with the top plate 304 during pouring, which could cause misalignment of the top plate 304 and affect the forming of the permeable dam component.

[0032] Example 2

[0033] like Figure 5 As shown, Embodiment 2 of this utility model proposes a permeable dam component, which is made using the permeable dam prefabrication mold proposed in Embodiment 1.

[0034] Please refer to Figure 5 The permeable dam component includes a parallel bottom plate 400 and a top plate 401. Two parallel vertical plates 402 are provided between the bottom plate 400 and the top plate 401, and each of the two vertical plates 402 has a through first opening 403. Two symmetrical inclined plates 404 are also provided between the bottom plate 400 and the top plate 401. The two inclined plates 404 are located between the two vertical plates 402, and each of the two inclined plates 404 has a through second opening 405.

[0035] Specifically, when the permeable dam component is placed in water, the length direction of the second opening 405 is consistent with the water flow direction, so that the permeable dam component plays the role of regulating flow and dissipating energy. In addition, the first opening 403 and the second opening 405 on the permeable dam component can make the flow of the permeable dam component more uniform and reduce scouring. At the same time, the permeable dam component allows water and sand to pass through to alleviate upstream siltation and provide passage and living space for aquatic organisms.

[0036] like Figure 5 As shown, two lifting rings 406 are spaced apart on the inclined side 404, and the two lifting rings 406 are respectively located on opposite sides of the second opening 405. The lifting rings 406 are provided on the inclined side 404 to facilitate the hoisting of the permeable dam component and the placement of the permeable dam component into the water, thereby facilitating the construction of a permeable dam using the permeable dam component.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
