Description

Technical Field

[0001] This application relates to the field of pipeline technology, and in particular to a water supply pipeline in soft soil environments. Background Technology

[0002] Municipal water supply pipelines are a major component of urban water supply systems. They are generally used for the distribution of water sources to supply water to every household in the city. Water is one of the essential basic materials for people's daily lives. In order to ensure a stable water supply, the construction requirements for urban municipal water supply pipelines must be strict.

[0003] The invention disclosed in CN116357813A proposes a municipal water supply pipeline and its construction method in soft soil environments. The municipal water supply pipeline includes an inner pipe, an outer pipe, a controller, a bending sensor, and a position correction device. The inner pipe has an outlet on its side wall, and a water valve is installed on the outlet. The outer pipe is sleeved on the inner pipe with a gap between them, and a spray nozzle is provided on its side wall. The controller is located within the gap. The bending sensor is used to detect the degree of bending of the inner and outer pipes. The position correction device is located within the gap and is used to correct the position of the inner pipe and its appearance.

[0004] The aforementioned municipal water supply pipeline and its construction method in a soft soil environment involves placing an inner pipe inside an outer pipe with a gap between them. However, the lack of a supporting structure between the inner and outer pipes makes the inner pipe more prone to bending the further away from the connection points at both ends, leading to a reduction in the pipeline's strength. Utility Model Content

[0005] The purpose of this utility model is to solve or at least alleviate the problem of existing municipal water supply pipelines and their construction methods in soft soil environments. The method involves placing an inner pipe inside an outer pipe with a gap between them. However, there is a lack of support structure between the inner and outer pipes, and the inner pipe is more prone to bending the further away from the connection points at both ends, which reduces the strength of the pipeline.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water supply pipeline for soft soil environments includes an inner pipe and an outer pipe. A support assembly is provided between the inner pipe and the outer pipe. The support assembly includes multiple support rings sleeved on the inner pipe. Multiple connecting rods are fixedly connected between every two support rings. Multiple arc-shaped support blocks in annular array are provided on the outer wall of each support ring. An extension assembly for adjusting the distance between the arc-shaped support blocks and the support rings is provided between the arc-shaped support blocks and the support rings. The outer pipe is sleeved on the support rings, and the arc-shaped support blocks abut against the inner wall of the outer pipe.

[0008] By adopting the above technical solution, during use, multiple support rings are first fitted onto the inner pipe, and the support rings are evenly distributed on the inner pipe by connecting rods. Then, the outer pipe is fitted onto the support rings, so that the arc-shaped support blocks all abut against the inner wall of the outer pipe, providing support between the outer and inner pipes, improving the stability of the outer and inner pipes, and avoiding the problem of the inner pipe being more prone to bending the further away from the two ends of the lack of support structure between the inner and outer pipes, which would reduce the strength of the pipe.

[0009] Optionally, the telescopic assembly includes multiple support tubes arranged in a ring on the outer wall of the support ring. A fixed plate is fixedly connected to the bottom of the inner end of each support tube. A support column is slidably arranged inside the support tube above the fixed plate. The end of the support column away from the support tube is fixedly connected to the arc-shaped support block. A threaded rod is provided on the upper surface of the fixed plate. The support column is sleeved on the threaded rod to form a threaded connection. The bottom end of the threaded rod passes through the fixed plate and is fixedly connected to a first bevel gear. The threaded rod is rotatably connected to the fixed plate. Rotating rods are rotatably connected between the multiple opposing support columns. The portion of the rotating rod located inside the support tube is fixedly connected to a second bevel gear. The second bevel gears mesh with the first bevel gears respectively.

[0010] By adopting the above technical solution, multiple rotating rods can be used to rotate multiple second bevel gears, which in turn can drive the first bevel gear to rotate, causing the threaded rod to rotate. This allows the support column to be raised and lowered with the cooperation of the support tube, adjusting the distance between the arc-shaped support block and the support ring, thus facilitating the support of outer tubes of different diameters.

[0011] Optionally, the inner wall of the support ring is rotatably connected with a plurality of first ball bearings in an annular array, and the side wall of the arc-shaped support block away from the support ring is rotatably connected with second ball bearings.

[0012] By adopting the above technical solution, the inner tube can be easily inserted into the support ring by the first ball bearing, and the outer tube can be easily fitted onto the arc-shaped support block by the second ball bearing.

[0013] Optionally, a scale is engraved on one side wall of each support column.

[0014] By adopting the above technical solution, the distance between the arc-shaped support block and the support ring can be precisely adjusted using a scale, ensuring that the distance between multiple arc-shaped support blocks and the support ring is the same. This prevents the arc-shaped support blocks from not being able to fully contact the inner wall of the outer tube when the distances are different, thus avoiding the problem of reduced support effect.

[0015] Optionally, limit grooves are provided on both sides of the inner sidewall of the support tube, and limit rods are fixedly connected in the limit grooves. Limit blocks are fixedly connected to the bottom ends of both sides of the support column, and the limit blocks are respectively located in the limit grooves and sleeved on the limit rods.

[0016] By adopting the above technical solutions, the stability of the support column sliding inside the support tube can be improved through the limiting groove, limiting block and limiting rod, and the separation of the support column from the threaded rod can be prevented.

[0017] Optionally, one end of each of the multiple rotating rods is fitted with the same limiting ring, and each rotating rod is threaded with a nut on both sides of the limiting ring.

[0018] By adopting the above technical solution, after adjusting the distance between the arc-shaped support block and the support ring, the limiting ring is sleeved on multiple rotating rods. Then, the nut is rotated so that the nut abuts against the two side walls of the limiting ring respectively. This can prevent the rotating rod from rotating and causing the arc-shaped support block to detach from the inner wall of the outer tube.

[0019] Optionally, two annular arrays of force-bearing plates are fixedly connected to the side wall of the outer tube.

[0020] By adopting the above technical solutions, the stress-bearing plate can increase the stress-bearing area of ​​the outer pipe and prevent the pipe from sinking.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. This application utilizes the coordinated arrangement of structures such as support rings, connecting rods, and arc-shaped support blocks. In use, multiple support rings are first fitted onto the inner pipe, and the support rings are evenly distributed on the inner pipe using connecting rods. Then, the outer pipe is fitted onto the support rings, ensuring that the arc-shaped support blocks all abut against the inner wall of the outer pipe, thus providing support between the outer and inner pipes and improving their stability. This avoids the problem of insufficient support structure between the inner and outer pipes, which can lead to bending of the inner pipe further away from the connection points at both ends, resulting in reduced pipe strength.

[0023] 2. By rotating multiple rotating rods, multiple second bevel gears can be rotated simultaneously, which in turn drives the first bevel gear to rotate, causing the threaded rod to rotate. This allows the support column to be raised and lowered with the cooperation of the support tube, adjusting the distance between the arc-shaped support block and the support ring, thus facilitating the support of outer tubes of different diameters.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] Please see Figure 1-3 A water supply pipeline for soft soil environments includes an inner pipe 1 for water supply and an outer pipe 2 for protecting the inner pipe 1. A support assembly is provided between the inner pipe 1 and the outer pipe 2 to prevent the inner pipe 1 from bending inside the outer pipe 2. The support assembly includes a support ring 3, a connecting rod 4 and an arc-shaped support block 5.

[0032] Multiple support rings 3 are provided and are respectively sleeved on the inner tube 1. Multiple connecting rods 4 are fixedly connected between every two support rings 3 to connect the multiple support rings 3 to each other and improve the stability of the support rings 3. Multiple sets of arc-shaped support blocks 5 are provided. Each set of arc-shaped support blocks 5 is provided with multiple arc-shaped support blocks 5 and is distributed in a circular array on the outer wall of the support ring 3 to abut against the inner wall of the outer tube 2, improve the stability of the inner tube 1 in the outer tube 2, and prevent the inner tube 1 from bending. A telescopic component is provided between the arc-shaped support blocks 5 and the support rings 3 to adjust the distance between the arc-shaped support blocks 5 and the support rings 3, so that the arc-shaped support blocks 5 can abut against the inner wall of the outer tube 2 with different diameters, improving the applicability of the support component. The outer tube 2 is sleeved on the support rings 3 and the arc-shaped support blocks 5 all abut against the inner wall of the outer tube 2.

[0033] In use, multiple support rings 3 are first fitted onto the inner pipe 1. The support rings 3 are evenly distributed on the inner pipe 1 by the connecting rod 4. Then, the outer pipe 2 is fitted onto the support rings 3, so that the arc-shaped support blocks 5 all abut against the inner wall of the outer pipe 2, providing support between the outer pipe 2 and the inner pipe 1, improving the stability of the outer pipe 2 and the inner pipe 1, and avoiding the problem that the inner pipe 1 is more prone to bending the farther away from the two ends of the connection, which would reduce the strength of the pipe.

[0034] Reference Figure 2 and Figure 3 The telescopic assembly includes multiple annular arrays of support tubes 6 on the outer wall of the support ring 3. A fixing plate 7 is fixedly connected to the bottom of the inner end of each support tube 6. A support column 8 is slidably disposed inside the support tube 6 above the fixing plate 7. The outer wall of the support column 8 fits against the inner wall of the support tube 6 to prevent wobbling during sliding. The end of the support column 8 furthest from the support tube 6 is fixedly connected to an arc-shaped support block 5 for supporting the arc-shaped support block 5. A threaded rod 9 is provided on the upper surface of the fixing plate 7. The support column 8 is sleeved on the threaded rod 9, forming a threaded connection to prevent free sliding of the support column 8 within the support tube 6. The bottom end of the threaded rod 9 penetrates the fixing plate 7 and is fixedly connected. A first bevel gear 10 is connected to a threaded rod 9, which is rotatably connected to a fixed plate 7. A rotating rod 11 is rotatably connected between multiple opposing support columns 8. The rotating rod 11 is fixedly connected to a second bevel gear 12 inside the support tube 6. The second bevel gear 12 meshes with the first bevel gear 10. By rotating the multiple rotating rods 11, the multiple second bevel gears 12 can be rotated, which can simultaneously drive the first bevel gear 10 to rotate, causing the threaded rod 9 to rotate. The support columns 8 are raised and lowered with the cooperation of the support tube 6, and the distance between the arc-shaped support block 5 and the support ring 3 can be adjusted to facilitate the support of outer tubes 2 of different diameters.

[0035] Reference Figure 2 The inner wall of the support ring 3 is rotatably connected with a plurality of first ball bearings 13 in an annular array. The side wall of the arc-shaped support block 5 away from the support ring 3 is rotatably connected with second ball bearings 14. The first ball bearings 13 facilitate the insertion of the inner tube 1 into the support ring 3, and the second ball bearings 14 facilitate the fitting of the outer tube 2 onto the arc-shaped support block 5.

[0036] Reference Figure 4 Each side wall of the support column 8 is engraved with a scale 15. The distance between the arc-shaped support block 5 and the support ring 3 can be precisely adjusted through the scale 15, so that the distance between multiple arc-shaped support blocks 5 and the support ring 3 is the same. This prevents the arc-shaped support blocks 5 from not being able to fully contact the inner wall of the outer tube 2 when the distances are different, which would reduce the support effect.

[0037] Reference Figure 5Limiting grooves 16 are provided on both sides of the inner sidewall of the support tube 6. Limiting rods 17 are fixedly connected in the limiting grooves 16. Limiting blocks 18 are fixedly connected to the bottom of both sides of the support column 8. The limiting blocks 18 are located in the limiting grooves 16 and are sleeved on the limiting rods 17. Through the limiting grooves 16, limiting blocks 18 and limiting rods 17, the stability of the support column 8 sliding in the support tube 6 can be improved, and the support column 8 can be prevented from disengaging from the threaded rod 9.

[0038] Reference Figure 2 and Figure 4 Multiple rotating rods 11 are fitted with the same limiting ring 19 at one end. Nuts 20 are threadedly connected to both sides of the limiting ring 19. After adjusting the distance between the arc-shaped support block 5 and the support ring 3, the limiting ring 19 is fitted onto the multiple rotating rods 11. Then, the nuts 20 are rotated so that they abut against the side walls of the limiting ring 19 on both sides. This can prevent the rotating rods 11 from rotating, which would cause the arc-shaped support block 5 to disengage from the inner wall of the outer tube 2.

[0039] Reference Figure 1 Two ring-shaped force-bearing plates 21 are fixedly connected to the side wall of the outer pipe 2. The force-bearing plates 21 can increase the force-bearing area of ​​the outer pipe 2 and prevent the pipe from sinking.

[0040] The implementation principle of this application is as follows: In use, the user first places multiple support rings 3 onto the inner tube 1, and uses connecting rods 4 to distribute the support rings 3 evenly on the inner tube 1. Then, by rotating multiple rotating rods 11, multiple second bevel gears 12 rotate, which simultaneously drives the first bevel gear 10 to rotate, causing the threaded rod 9 to rotate. This allows the support column 8 to be raised and lowered with the cooperation of the support tube 6, adjusting the distance between the arc-shaped support block 5 and the support rings 3 to adapt to outer tubes 2 of different diameters. Afterward, the limiting ring 19 is placed on the multiple rotating rods 11, and then... Rotating nut 20 causes it to abut against the side walls of the limiting ring 19 on both sides, preventing the rotating rod 11 from rotating during use and causing displacement of the arc-shaped support block 5. Finally, the outer tube 2 is fitted onto the support ring 3, so that the arc-shaped support block 5 abuts against the inner wall of the outer tube 2, providing support between the outer tube 2 and the inner tube 1, improving the stability of the outer tube 2 and the inner tube 1, and avoiding the problem of the inner tube 1 being more prone to bending and reducing the strength of the pipe due to the lack of a support structure between the inner tube 1 and the outer tube 2.
