Abstract
Description
Technical Field
[0001] The utility model relates to farmland reconstruction, in particular to a road culvert structure. Background Art
[0002] There are usually canals on both sides of the farmland, which makes it convenient for the pump station to pump water into the canal. After opening the gate on the canal, the water can be introduced into the farmland for irrigation. The canal is generally composed of multiple sections of canals connected, with a U-shaped or U-shaped cross-section and an open top surface, so that the situation in the canal can be seen intuitively. In addition, it is necessary to consider the entry of agricultural machinery into the farmland. Therefore, some of the canals need to be set up with a downhill slope. The canals on both sides of the downhill slope are connected by setting up a culvert structure. The culvert structure generally uses pipes and prefabricated concrete parts, and backfills the soil above the pipe as a road surface. The existing culvert structure still has problems: due to the different shapes of the cross-sections of the canal and the pipe, the connection between the two is unstable and prone to leakage. Utility Model Content

[0028] See also Figure 1 A culvert structure includes two channels 1, a plurality of pipes 2, a plurality of connecting sections 3, a plurality of first concrete members 4 and two second concrete members 5.
[0029] The cross-sections of the two channels 1 are U-shaped. The channel 1 is composed of multiple prefabricated channel 1 sections installed in the corresponding pits, and the space between the two channels 1 is left empty to design a slope for agricultural machinery to pass through.
[0030] Each pipe 2 is also prefabricated with reinforced concrete. The length of one pipe 2 is fixed. The number of pipes 2 is determined according to the designed width of the road surface. Two pipes 2 are used as an example in the attached figure. The inner diameter of the pipe 2 matches the arc section of the channel 1, that is, it is equal to the inner diameter of the arc section of the channel 1. Multiple pipes 2 are arranged between two channels 1. That is, on the one hand, the two channels 1 are connected by the pipe 2, and on the other hand, the pipe 2 is closed compared to the channel 1, and soil can be backfilled on the top as the road surface.
[0031] A plurality of connecting sections 3 are sequentially connected between two adjacent pipes 2, that is, the number of connecting sections 3 is related to the number of pipes 2, more precisely, the number of connecting sections 3 is one less than the number of pipes 2. Both ends of the connecting section 3 are in the shape of a socket that matches the pipe 2. That is, the inner diameter of the middle part of the connecting section 3 is the same as the inner diameter of the pipe 2, and the inner diameter of the two end parts of the connecting section 3 becomes larger, so that the ends of the pipe 2 can be inserted and matched to the connection between the concrete and the rubber ring to connect and seal.
[0032] See also Figure 2Optionally, there are a first rubber ring 2a and a second rubber ring 2b between the connecting section 3 and the pipe 2. The first rubber ring 2a is arranged between the connecting section 3 and the end face of the pipe 2, and the second rubber ring 2b is arranged between the inner wall of the connecting section 3 and the outer wall of the pipe 2. The area between the connecting section 3 and the pipe 2 between the first rubber ring 2a and the second rubber ring 2b is a first concrete filling layer 2c. That is, in the process of connecting the connecting section 3 and the pipe 2, the first rubber ring 2a is installed first, and then concrete is filled in the connection between the two, and then the second rubber ring 2b is installed, and the first concrete filling layer 2c is formed after the filled concrete solidifies.
[0033] Furthermore, the cross section of the first rubber ring 2a is T-shaped, and the vertical portion is located between the connecting section 3 and the end surface of the pipe 2. In this way, the installation of the first rubber ring 2a between the connecting section 3 and the pipe 2 is convenient.
[0034] Furthermore, the end faces at both ends of the connecting section 3 are provided with triangular plastering 2d connected to the outer wall of the pipeline 2. In this way, the installation of the second rubber ring 2b is more stable, and the sealing of the connection between the connecting section 3 and the pipeline 2 is also better.
[0035] A plurality of first concrete members 4 are placed under a plurality of pipes 2 and a plurality of connecting sections 3. Specifically, the first concrete members 4 are also prefabricated members, with a circular arc groove on the top, and the outer diameter of the middle portion of the connecting section 3 can be the same as the outer diameter of the pipe 2. Specifically, the first concrete members 4 are first placed in the pit, and then the pipes 2 and connecting sections 3 are placed in the pit and stacked on the first concrete members 4.
[0036] See also Figure 3 , two second concrete members 5 are respectively stacked on top of the pipes 2 on both sides. Specifically, the second concrete members 5 are also prefabricated members with arc grooves at the bottom. The second concrete members 5 overlap with the end face of the pipe 2 close to the channel 1 and can cover the end face of the channel 1. In this way, the end face of the channel 1 can have a groove, and a sealing tape 1a is placed in the groove, which is matched to the second concrete member 5 and the end face of the pipe 2 close to the channel 1, and the second concrete filling layer covering the sealing tape 1a in the groove. Accordingly, a space for backfilling soil to cover the pipe 2 and the connecting section 3 is formed between the two second concrete members 5, the outer wall of the pipe 2, and the outer wall of the connecting section 3.
[0037] See also Figure 4 Optionally, there are fasteners 5a for fixing the two second concrete members 5 and the corresponding first concrete members 4. In this way, the position of the second concrete member 5 can be adjusted conveniently, and the second concrete member 5 and the end surface of the pipeline 2 close to the channel 1 can be overlapped.
[0038] Optionally, the first concrete members 4 on both sides are partially placed under the corresponding channels 1. That is, the outer diameter of the arc portion of the channel 1 is equal to the outer diameter of the pipe 2. When the pipe 2 is installed between the two channels 1, it is more convenient for the pipe 2 to be aligned with the arc portion of the channel 1.
