Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a prefabricated culvert assembly structure. Background Technology

[0002] During pipeline installation, it is often necessary to lay pipelines underground. To prevent frequent ground construction, prefabricated culverts are often used for pipeline installation.

[0003] In existing technologies, such as the Chinese utility model patent with publication number CN206457735U, a highly flexible prefabricated reinforced concrete culvert is disclosed. This method allows large reinforced concrete culverts to be disassembled into modular reinforced concrete components and assembled by sequentially arranging several reinforced concrete members. This makes the production process and quality easier to control, reduces the impact of weather factors on culvert construction, and lowers project costs. However, the above technical solution still has the following drawbacks: Because concrete components shrink during curing, the upper and lower surfaces of the cured support components and inverted T-shaped components are prone to deformation or unevenness. This can lead to the support components becoming skewed during assembly, failing to meet construction requirements. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a prefabricated culvert assembly structure. Through the setting of a correction mechanism, the position of the side plates can be corrected during the assembly process to avoid skewing and help improve construction efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a prefabricated culvert assembly structure, including a base, connecting seats, side plates, a top cover, and a correction mechanism. Connecting seats are provided at both ends of the base and the top cover. Two side plates are vertically arranged between the base and the top cover. The two ends of the side plates are respectively connected to one of the connecting seats through the correction mechanism. The correction mechanism includes a threaded pipe, a threaded steel bar, a trapezoidal block, a wedge block, and an adjusting bolt. The connecting seat is provided with a slot. The threaded pipe is vertically fixed in the slot. One end of the threaded steel bar is threadedly connected to the threaded pipe. Trapezoidal blocks that fit into the slot are provided at both ends of the side plates. Wedge blocks are symmetrically arranged on both sides of the trapezoidal blocks, and the wedge blocks are slidably connected to the inner wall of the slot. The adjusting bolt is rotatably connected to the connecting seat, and one end of the adjusting bolt is threadedly connected to the wedge block.

[0007] In a preferred embodiment of this invention, a sealing gasket is provided inside the slot.

[0008] In a preferred embodiment of this invention, the threaded steel bar is provided with a rotating handle.

[0009] In a preferred embodiment of this invention, a grouting pipe is provided on one side of the connecting seat, and one end of the grouting pipe is connected to the slot.

[0010] In a preferred embodiment of this invention, both the connecting seat and the side plate are provided with lifting rings.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model proposes a prefabricated culvert assembly structure. Through a correction mechanism, the position of the side plates can be corrected during assembly to prevent skewing and improve construction efficiency. Simultaneously, wedge-shaped and trapezoidal blocks cooperate to fix the side plates and connecting seats together, facilitating subsequent grouting. Concrete grout can be injected into the slots through grouting holes. After the concrete grout solidifies, it strengthens the connection between the connecting seat and the side plates, improving connection strength and meeting construction requirements.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. For example... Figure 1-4As shown, the embodiment provides a prefabricated culvert assembly structure, including a base 1, a connecting seat 2, side plates 3, a top cover 4, and a correction mechanism 5. Connecting seats 2 are provided at both ends of the base 1 and the top cover 4. Two side plates 3 are vertically arranged between the base 1 and the top cover 4. The two ends of each side plate 3 are connected to one of the connecting seats 2 via the correction mechanism 5. The correction mechanism 5 includes a threaded pipe 51, a threaded steel bar 52, a trapezoidal block 53, a wedge block 54, and an adjusting bolt 55. A slot 21 is provided on the connecting seat 2. The threaded pipe 51 is vertically fixed inside the slot 21. One end of the threaded steel bar 52 is threadedly connected to the threaded pipe 51. Trapezoidal blocks 53 are provided at both ends of the side plates 3 to engage with the slots 21. Wedge blocks 54 are symmetrically arranged on both sides of the trapezoidal blocks 53, and the wedge blocks 54 are slidably connected to the inner wall of the slot 21. The adjusting bolt 55 is rotatably connected to the connecting seat 2, and one end of the adjusting bolt 55 is threadedly connected to the wedge block 54. In this embodiment, the foundation 1, side plates 3, and top cover 4 are all flat structures, with the top cover 4 positioned parallel to the foundation 1 directly above it. A connecting seat 2 is located at each end of the top surface of the foundation 1, and a connecting seat 2 is located at each end of the bottom surface of the top cover 4. The two connecting seats 2 on the foundation 1 and the two connecting seats 2 on the top cover 4 are aligned one-to-one. The connecting seat 2 is a T-shaped block structure, a rectangular block structure, or other shapes, and the connection between the connecting seat 2 and the foundation 1, and between the connecting seat 2 and the top cover 4, is integrally formed to ensure that the connection strength meets construction requirements. Two side plates 3 are provided, arranged parallel to each other. The foundation 1, the two side plates 3, and the top cover 4 can form a closed rectangular frame structure, thus obtaining a culvert. The foundation 1, connecting seats 2, side plates 3, and top cover 4 are all made of concrete. The included alignment mechanism 5 corrects the position of the side plate 3, ensuring it remains perpendicular to the base 1 and top cover 4 during assembly. Each slot 21 has a threaded tube 51 at each of its four corners, with one end of the threaded tube 51 embedded in the connecting seat 2 for secure fixing. A threaded steel rod 52 is coaxially arranged with the threaded tube 51, with one end extending beyond the threaded tube 51. The threaded steel rod 52 has threads on its circumference, allowing it to move upwards relative to the threaded tube 51 when rotated, thus enabling adjustment of the threaded steel rod 52. The extension length allows for adjustment of the position of the side plate 3; the small end of the trapezoidal block 53 is connected to the side plate 3, and the large end of the trapezoidal block 53 is inserted into the slot 21; the wedge block 54 can slide left and right in the slot 21, and the inclined surface of the wedge block 54 faces the trapezoidal block 53; the adjusting bolt 55 is arranged horizontally, and one end of the adjusting bolt 55 is threaded, so that when the adjusting bolt 55 rotates, it can drive the wedge block 54 to slide left and right. When the inclined surfaces of the two wedge blocks 54 simultaneously abut against the inclined surfaces of the trapezoidal block 53, the trapezoidal block 53 can be clamped and fixed, thereby fixing the side plate 3 and the connecting seat 2 as one unit.The number of adjusting bolts 55 is equal to the number of wedge blocks 54, and each adjusting bolt 55 is connected to one of the wedge blocks 54.

[0020] Specifically, a sealing gasket 22 is provided inside the slot 21. In this embodiment, the sealing gasket 22 is made of waterproof rubber material, which is not only waterproof but also has a certain degree of elasticity. When the trapezoidal block 53 is inserted into the slot 21, the bottom surface of the side plate 3 will first abut against the sealing gasket 22 and compress it, thereby sealing the slot 21, which facilitates the subsequent injection of concrete grout into the slot 21 and prevents concrete grout leakage.

[0021] Specifically, a rotating handle 56 is provided on the threaded steel bar 52. In this embodiment, the rotating handle 56 is coaxially fixed on the threaded steel bar 52, and the rotating handle 56 allows the operator to easily rotate the threaded steel bar 52.

[0022] Specifically, a grouting pipe 6 is provided on one side of the connecting seat 2, and one end of the grouting pipe 6 is connected to the slot 21. In this embodiment, the grouting pipe 6 has an L-shaped structure. Concrete slurry can be injected into the slot 21 through the grouting pipe 6. After the concrete slurry solidifies, the side plate 3 and the connecting seat 2 can be firmly fixed, and their connection strength can be improved. At the same time, the waterproof effect can also be improved.

[0023] Specifically, lifting rings 7 are provided on both the connecting seat 2 and the side plate 3. In this embodiment, the lifting rings 7 enable the lifting operations of the foundation seat 1, the side plate 3, and the top cover 4, facilitating construction.

[0024] This embodiment also provides a construction method for a prefabricated culvert assembly structure, including the following steps:

[0025] S1. Place the foundation base 1 horizontally on the ground or in a trench;

[0026] S2. Hoist the side plate 3 above the base 1, aligning the bottom of the side plate 3 with the slot 21 on one of the connecting seats 2 on the base 1. Simultaneously, rotate the handle 56 to drive the threaded steel bar 52 to rotate, adjusting the extension length of the threaded steel bar 52 as needed to ensure that the side plate 3 is in a vertical position after being placed on the connecting seat 2. Then, rotate the adjusting bolt 55, which drives the two wedge blocks 54 to move closer together and clamp the trapezoidal block 53 to fix it, thereby fixing the side plate 3 and the base 1 as one unit.

[0027] S3. After both side plates 3 are installed on the base 1, the top cover 4 is hoisted above the side plates 3, and the slot 21 of the connecting seat 2 on the top cover 4 is aligned with the top of the side plate 3. Then repeat the steps in S2 to fix the side plate 3 and the top cover 4 into one piece.

[0028] S4. Inject concrete slurry into slot 21 through grouting pipe 6. After the concrete slurry solidifies, the construction work is completed and the culvert is obtained.
