Description

Technical Field

[0001] This utility model is a prefabricated three-stage sedimentation tank, belonging to the field of municipal road drainage engineering equipment. Background Technology

[0002] Most municipal road drainage projects currently under construction require dewatering before construction can begin. This involves lowering the water level below the design level. During dewatering, the water source is transported to a three-stage sedimentation tank to remove suspended solids. Through three stages of sedimentation, the concentration of suspended solids in the water is gradually reduced, thus purifying the water and ensuring that clean water can be returned after the municipal road drainage project is completed.

[0003] In existing technologies, conventional three-stage sedimentation tanks are constructed using red brick masonry (with plastering), which is time-consuming and labor-intensive. The construction process is lengthy, and after the masonry is completed, it takes time for the cement to solidify, preventing the three-stage sedimentation tank from being put into use quickly and reducing the assembly efficiency. Furthermore, the three-stage sedimentation tank needs to be dismantled after the completion of municipal road drainage projects. Dismantling requires manual labor and machinery, and during the dismantling process, some brick materials break and cannot be reused, increasing the project cost of municipal road drainage projects.

[0004] In summary, this utility model provides a prefabricated three-stage sedimentation tank to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a prefabricated three-stage sedimentation tank, thereby solving the problem mentioned in the background art that sedimentation tanks cannot be quickly disassembled and assembled, and that excessive material consumption during the disassembly and assembly process increases the project cost of municipal road drainage projects.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a prefabricated three-stage sedimentation tank, comprising three bottom plates, four side plates evenly embedded from left to right between the tops of the three bottom plates, a horizontal plate embedded between opposite sides of each pair of side plates and on the front and rear sides of the top of the bottom plate, a first retaining frame fixedly connected to the front and rear sides of each side plate, a second retaining frame fixedly connected to one side of each horizontal plate and on the top of the first retaining frame, a retaining rod penetrating the top of each second retaining frame, the bottom end of the retaining rod penetrating the first retaining frame and extending to the bottom of the first retaining frame.

[0007] Furthermore, each base plate has a U-shaped groove on its top, each side plate has a locking plate fixedly installed on both sides of its bottom, and each cross plate has a locking strip fixedly installed at its bottom.

[0008] Furthermore, the bottom of each side plate is engaged with the top of the base plate via a snap-fit ​​plate, and the bottom of each horizontal plate is engaged with the top of the base plate via a snap-fit ​​strip.

[0009] Furthermore, the top of each lever is bent at a right angle, and the first and second card frames are interlocked by the levers.

[0010] Furthermore, the top and bottom of each first card frame are open, and the top and bottom of each second card frame are also open.

[0011] Furthermore, drainage outlets are provided at the top of both side panels, and the bottom of the first card frame is in contact with the top of the second card frame.

[0012] Furthermore, the front and rear sides of both sides of the side plate are provided with slots for fitting the cross plate, and the inner wall of each slot is fixedly bonded with a layer of sealant.

[0013] The beneficial effects of this utility model are:

[0014] By aligning the bottom clips of the side panels with the U-shaped grooves at the top of the base plate, the side panels and base plate are snapped together. The bottom clips of each horizontal plate are then aligned with the U-shaped grooves at the top of the three base plates. Simultaneously, the bottom sides of the horizontal plates are aligned with the tops of the slots on opposite sides of the two side panels. Pushing the horizontal plates downwards completes the rapid snapping together of the horizontal plates with the base plate and side panels. The top of the lever is bent and passed through the second and first clip frames, completing the rapid assembly of the three-stage sedimentation tank. This eliminates the need for welding and masonry in assembling the prefabricated sedimentation tank, effectively improving the assembly efficiency. Furthermore, the plates used in the overall assembly of the sedimentation tank are undamaged during disassembly and can be reused, effectively saving project costs.

[0015] Each slot has a sealing layer fixedly bonded to its inner wall. The sealing layer improves the connection and sealing when the horizontal plate and the slot are fitted together, thereby effectively improving the overall water-stopping effect of the sedimentation tank.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a prefabricated three-stage sedimentation tank, comprising three bottom plates 1, four side plates 2 evenly embedded from left to right between the tops of the three bottom plates 1, and a horizontal plate 4 embedded between opposite sides of each pair of side plates 2 and on the front and rear sides of the top of the bottom plate 1. A first retaining frame 3 is fixedly connected to the front and rear sides of both sides of each side plate 2, and a second retaining frame 5 is fixedly connected to one side of each horizontal plate 4 and on the top of the first retaining frame 3. A retaining rod 6 passes through the top of each second retaining frame 5, and the bottom end of the retaining rod 6 passes through the first retaining frame 3 and extends below the first retaining frame 3. Waterproof adhesive is applied to the joints between the side plates 2, horizontal plates 4, and bottom plates 1 to improve the overall waterproofness of the sedimentation tank. The base plate 1 is made of aluminum alloy and thin iron plate. Each base plate 1 has a U-shaped groove 7 on the top. Each side plate 2 has a clamping plate 10 fixedly installed on both sides of the bottom. Each horizontal plate 4 has a clamping strip 9 fixedly installed on the bottom. The bottom of each side plate 2 is connected to the U-shaped groove 7 on the top of the base plate 1 through the clamping plate 10. The bottom of each horizontal plate 4 is connected to the U-shaped groove 7 on the top of the base plate 1 through the clamping strip 9. The top of each clamping rod 6 is bent at a right angle. The bent end of the clamping rod 6 makes it easy to hold the clamping rod 6 through the first clamping frame 3 and the second clamping frame 5. The first clamping frame 3 and the second clamping frame 5 are connected to each other through the clamping rod 6. The top and bottom of each first clamping frame 3 are open. The top and bottom of each second clamping frame 5 are open.

[0025] Please see Figure 2-5 The top of each of the two side plates 2 is provided with a drain outlet 8. The bottom of the first card frame 3 is in contact with the top of the second card frame 5. The front and rear sides of both sides of the side plate 2 are provided with card slots 11 that are fitted into the horizontal plate 4. The inner wall of each card slot 11 is fixedly bonded with a sealing layer 12. The sealing layer 12 can improve the connection and sealing performance when the horizontal plate 4 and the card slot 11 are fitted together.

[0026] Detailed Implementation: By aligning the locking plates 10 at the bottom of the four side plates 2 with the U-shaped grooves 7 at the top of the three base plates 1 respectively, and evenly embedding them between the tops of the three base plates 1 from left to right, and then aligning the locking strips 9 at the bottom of each horizontal plate 4 with the U-shaped grooves 7 at the top of the three base plates 1, while aligning the bottom sides of the horizontal plate 4 with the tops of the slots 11 on opposite sides of the two side plates 2, the horizontal plate 4 is pushed downwards, moving the horizontal plate 4 between the two slots 11, and causing the locking strips 9 at the bottom of the horizontal plate 4 to move into the interior of the U-shaped grooves 7, so that two horizontal plates 4 are locked between opposite sides of every two side plates 2, and the bottom of the second locking frame 5 on the horizontal plate 4 can contact the top of the first locking frame 3, and the first locking frame 3... The top opening is aligned with the top opening of the second frame 5. The top of the lever 6 is bent and the bottom of the lever 6 is aligned with the top of the second frame 5. The lever 6 is then moved downwards so that it passes through the first frame 3, thus enabling the quick connection between the second frame 5 and the first frame 3. This allows for the rapid assembly of the three-stage sedimentation tank without the need for welding or masonry, effectively improving the assembly efficiency of the three-stage sedimentation tank. Furthermore, the plates used in the overall assembly of the sedimentation tank are undamaged during disassembly and can be reused, effectively saving project costs. Waterproof adhesive is applied to the joints of the side plates 2, the horizontal plates 4, and the bottom plate 1 to improve the overall waterproofness of the sedimentation tank.

[0027] Each slot 11 has a sealing layer 12 fixedly bonded to its inner wall. The sealing layer 12 can improve the connection and sealing when the horizontal plate 4 and the slot 11 are fitted together, thereby effectively improving the overall water-stopping effect of the sedimentation tank.

[0028] Two horizontal plates 4, two side plates 2, and one bottom plate 1 form a sedimentation tank. Three bottom plates 1, four side plates 2, and six horizontal plates 4 form three sedimentation tanks. The top of the two side plates 2 are provided with drain outlets 8. When the sedimentation tank on the left is full of sediment, the excess water can overflow through the drain outlet 8 on the top of one side plate 2 and be transported to the middle sedimentation tank for secondary sedimentation. After secondary sedimentation, the excess water can overflow through the drain outlet 8 on the top of the other side plate 2 and be transported to the right sedimentation tank for tertiary sedimentation, thus completing the three-stage sedimentation of sewage.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
