Description

Technical Field

[0001] This utility model relates to the field of plastic drainage boards, specifically a plastic drainage board with irregularly shaped channels inside. Background Technology

[0002] Plastic drainage boards (also known as plastic drainage strips or plastic sandwich panels) are a key material widely used in civil engineering and building waterproofing and drainage systems. Their core function is to achieve efficient drainage, seepage prevention, and protection through structural design.

[0003] In existing technology, plastic drainage boards consist of a board body and protrusions. During use, a drainage strip is fitted onto the plastic drainage board. The inner wall of the drainage strip forms several irregularly shaped channels with the board body and protrusions. During use, the drainage strip is driven into the soft soil foundation using a board insertion machine. Under the action of the upper preload, the pore water in the soft soil foundation is drained from the plastic drainage board into the sand layer or horizontal plastic drainage pipe laid on top, and then discharged from other places, accelerating the consolidation of the soft foundation. During the production process, the plastic drainage board needs to be cut to a standard length for easy storage and transportation. During use, after a portion of the plastic drainage board is driven into the soft soil layer, it needs to be cut again. Then, after a certain distance, another portion of the plastic drainage board is driven into the soft soil layer. Therefore, a single end of the plastic drainage board can be cut multiple times and driven into the soft soil layer in multiple sections during use.

[0004] However, the cutting of plastic drainage boards during use is done manually. This results in a section of the plastic drainage board being shorter than the thickness of the soft soil layer after the final insertion and cutting. This section is insufficient to drain water from the soft soil layer at the target depth and must be discarded, leading to waste of the plastic drainage board. Utility Model Content

[0005] The purpose of this invention is to provide a plastic drainage board with an internally shaped channel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic drainage board with an internal irregularly shaped channel, comprising: a board body, wherein a connecting groove is formed on the surface of the board body, one end of a connecting plate is movably inserted into the connecting groove, the other end of the connecting plate is movably inserted into another set of connecting grooves, the other set of connecting grooves is formed on the surface of another set of board bodies, a connecting block insertion groove is formed on the surface of the board body, a connecting block is fixed on the surface of the connecting plate, the connecting block is movably inserted into the connecting block insertion groove, and a limit mechanism is provided between the connecting block insertion groove and the connecting block.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit 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.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a plastic drainage board with an internal irregularly shaped channel, comprising: a board body 1, a connecting groove 2 formed on the surface of the board body 1, one end of a connecting plate 3 being movably inserted into the connecting groove 2, the other end of the connecting plate 3 being movably inserted into another set of connecting grooves 2, the other set of connecting grooves 2 being formed on the surface of another set of board bodies 1, a connecting block insertion groove 4 formed on the surface of the board body 1, a connecting block 10 fixed on the surface of the connecting plate 3, the connecting block 10 being movably inserted into the connecting block insertion groove 4, a limiting mechanism being provided between the connecting block insertion groove 4 and the connecting block 10, the connecting plate 3 having a rectangular board structure, the connecting block 10 having a rectangular block structure, two sets of connecting blocks 10 being provided on one set of connecting plates 3, the two sets of connecting blocks 10 being movably inserted into the connecting block insertion grooves 4 on the two sets of board bodies 1 respectively.

[0021] In actual use, when the remaining length of plate 1 is insufficient to meet the requirements after being cut during use, the remaining part of plate 1 is removed from the plate insertion machine. Then, the end of plate 1 is joined together with the end of another set of plate 1. The connecting plate 3 is inserted into the connecting groove 2 of the two sets of plate 1, and the two sets of connecting blocks 10 are also inserted into the connecting block insertion groove 4 of the two sets of plate 1 respectively. The limiting mechanism limits the connecting block 10 in the connecting block insertion groove 4, and the connecting plate 3 completes the connection of the two sets of plate 1. After that, the two sets of plate 1 are reinstalled into the plate insertion machine, so that the remaining part of plate 1 can be reused, reducing waste.

[0022] Example 2: Based on Example 1, to achieve the limiting mechanism, the limiting mechanism includes: a limiting block mounting groove 5, a limiting groove 6, and a limiting block 7. The limiting block mounting groove 5 is formed on the surface of the connecting block 10, the limiting groove 6 is formed on the inner wall of the connecting block insertion groove 4, one end of the limiting block 7 is movably inserted into the limiting block mounting groove 5, and the other end of the limiting block 7 is movably inserted into the limiting groove 6. Both the limiting block mounting groove 5 and the limiting groove 6 are rectangular groove structures, and the limiting block 7 is a wedge-shaped block structure. One end of the positioning block 7 that extends into the positioning block mounting groove 5 is fixed with a limiting spring 8, and the other end of the limiting spring 8 is fixed to the inner wall of the positioning block mounting groove 5. One end of the positioning block 7 that extends into the positioning groove 6 is provided with an inclined surface 9. A sliding groove 11 is opened on the surface of the positioning block mounting groove 5. A slider 12 is fixed on the surface of the positioning block 7. There are two sets of sliding grooves 11 and two sets of sliders 12. The two sets of sliding grooves 11 and two sets of sliders 12 are symmetrically distributed about the positioning block 7. The two sets of sliders 12 are slidably connected in the two sets of sliding grooves 11 respectively.

[0023] When the connecting block 10 is inserted into the connecting block insertion slot 4, the connecting block insertion slot 4 slides over the inclined surface 9, causing the limiting block 7 to be fully pushed into the limiting block mounting slot 5. The limiting spring 8 is compressed. When the connecting block 10 is inserted into the connecting block insertion slot 4, the limiting block mounting slot 5 and the limiting slot 6 are aligned. The limiting spring 8 pushes one end of the limiting block 7 into the limiting slot 6, while the other end of the limiting spring 8 remains in the limiting block mounting slot 5. This effectively limits the connecting block 10 in the connecting block insertion slot 4. A slider 12 is fixed on the limiting block 7. A sliding groove 11 is provided on the inner wall of the limiting block mounting slot 5. The slider 12 is slidably connected in the sliding groove 11, which can prevent the limiting block 7 from coming out of the limiting block mounting slot 5.

[0024] In actual use, when the remaining length of plate 1 is insufficient to meet requirements after being cut during use, the remaining part of plate 1 is removed from the plate insertion machine. Then, the end of plate 1 is joined with the end of another set of plate 1. The connecting plate 3 is inserted into the connecting groove 2 of the two sets of plate 1, and the two sets of connecting blocks 10 are also inserted into the connecting block insertion groove 4 of the two sets of plate 1 respectively. The limiting mechanism keeps the connecting block 10 in the connecting block insertion groove 4, thus completing the connection of the two sets of plate 1. Afterwards, the two sets of plate 1 are reinstalled into the plate insertion machine, which allows the remaining part of plate 1 to be reused, reducing waste. When the connecting block 10 is inserted into the connecting block slot 4, the connecting block slot 4 slides over the inclined surface 9, so that the limiting block 7 is completely pushed into the limiting block mounting slot 5, and the limiting spring 8 is compressed. When the connecting block 10 is inserted into the connecting block slot 4, the limiting block mounting slot 5 and the limiting slot 6 are aligned. The limiting spring 8 pushes one end of the limiting block 7 into the limiting slot 6, and the other end of the limiting spring 8 stays in the limiting block mounting slot 5, thus limiting the connecting block 10 in the connecting block slot 4. A slider 12 is fixed on the limiting block 7. A sliding groove 11 is opened on the inner wall of the limiting block mounting slot 5. The slider 12 is slidably connected in the sliding groove 11, which can prevent the limiting block 7 from coming out of the limiting block mounting slot 5.
