Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, and in particular to a prefabricated structure and assembly method for pipelines in underground integrated pipe corridors in crustally active areas. Background Technology

[0002] Underground integrated utility tunnels are underground urban pipeline corridors, which are tunnel spaces built underground in cities to integrate various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage. They are equipped with dedicated inspection ports, hoisting ports and monitoring systems, and are implemented in a unified manner in terms of planning, design, construction and management. They are important infrastructure and "lifelines" to ensure the operation of cities. The multiple water pipes used for water supply and drainage are often spliced ​​and assembled using flanges and bolts.

[0003] When the underground utility tunnel is located in an active crustal zone, the frequent vibrations can cause the bolts used to connect and assemble the water pipes to rotate due to the vibration force, resulting in loosening at the joints of the water pipes. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: when the underground integrated pipe gallery is located in an active crustal zone, the multiple bolts used to splice and assemble water pipes are easily affected by vibration forces and rotate, resulting in loosening at the splicing and assembly points of multiple water pipes. Therefore, this invention proposes a prefabricated structure for pipes in underground integrated pipe galleries in active crustal zones and its assembly method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An assembled structure for pipelines in an underground integrated pipe gallery in an active crustal zone includes a water pipe. A first flange and a second flange are fixedly sleeved at both ends of the water pipe. The surface of the first flange has multiple threaded openings in a circumferential shape, and the surface of the second flange has multiple threaded fastening grooves in a circumferential shape. Bolts are threaded into each of the multiple threaded openings, and branch pipes are fixedly installed on the surface of the water pipe.

[0007] The first flange has multiple spring rods fixedly installed in a circumferential shape on its surface. One end of each spring rod is fixedly installed with a mounting plate. The mounting plate has a through-hole on its surface. A hollow rod with one closed end is fixedly installed inside the through-hole. A suction cup is fixedly installed at the open end of the hollow rod. The multiple suction cups correspond to the positions of multiple threaded openings.

[0008] As a preferred embodiment, the hollow rod has a rotating opening at one closed end, and a rotating rod is rotatably installed inside the rotating opening. A vent is provided on the surface of the hollow rod. A sealing plate for blocking the vent is fixedly installed at the end of the rotating rod located inside the hollow rod via a connecting rod. A fixing block is fixedly installed at the end of the rotating rod located outside the hollow rod. A torsion spring is sleeved on the rotating rod, and the two ends of the torsion spring are fixedly connected to the fixing block and the hollow rod, respectively.

[0009] As a preferred embodiment, connecting rods are fixedly mounted on the surface of the mounting plate, and mounting rings are fixedly mounted on the ends of the multiple connecting rods away from the mounting plate. The movement of the mounting rings is controlled by a pressing component.

[0010] As a preferred embodiment, the pressure-blocking assembly includes two hollow tubes with one closed end, two piston rods respectively slidably and sealed inside the two hollow tubes, two first air guide tubes, two corrugated tubes with one closed end, and two pressure blocks fixedly installed at one end of the two corrugated tubes. The water pipes are symmetrically fixedly mounted with fixing rings. The two hollow tubes are respectively fixedly installed inside the two fixing rings. The two first air guide tubes are respectively fixedly installed on the surface of the two hollow tubes. The two pressure blocks abut against the mounting rings. The open ends of the two corrugated tubes are respectively fixedly sleeved at the openings of the two first air guide tubes. The piston rods are controlled to move laterally and reciprocally by a drive assembly.

[0011] As a preferred embodiment, the drive assembly includes a rotating rod horizontally rotatably mounted inside a water pipe, a rotating blade fixedly sleeved on the rotating rod, and a reciprocating screw fixedly mounted at one end of the rotating rod. A sliding plate is threaded onto the reciprocating screw. A sliding opening is formed on the surface of the water pipe. One end of the sliding plate extends out of the sliding opening, and arc-shaped rods are fixedly mounted on both its front and rear surfaces. Two arc-shaped rods are respectively fixedly connected to two piston rods. A rotating ring is rotatably sleeved on the rotating rod. Straight rods are symmetrically fixedly mounted on the surface of the rotating ring. One end of each of the two straight rods is fixedly connected to the inner wall of the water pipe. Sliding grooves are horizontally formed on the left and right walls of the sliding opening. Sealing plates are fixedly mounted on the left and right side walls of the sliding plate. The two sealing plates are slidably and sealingly inserted into the two sliding grooves.

[0012] As a preferred embodiment, a filter screen is fixedly installed inside the branch pipe, and a second air guide pipe is fixedly installed on the surface of the hollow pipe. One end of one of the second air guide pipes is inserted into the water pipe, and a rod is slidably inserted into the pipe opening. An installation plate is fixedly installed at the bottom end of the rod. The diameter of the installation plate is smaller than the diameter of the filter screen. Multiple cleaning rods with tapered bottoms are fixedly installed on the surface of the installation plate. The multiple cleaning rods correspond to the positions of multiple filter holes on the surface of the filter screen. One end of another second air guide pipe is inserted into the branch pipe, and a first threaded rod is slidably inserted into the pipe opening. A first installation rod is rotatably installed at the center of the filter screen. A first threaded groove is opened at one end of the first installation rod, and the first threaded rod is threaded into the first threaded groove. Scraper rods are symmetrically fixedly installed on the surface of the first installation rod, and the scraper rods slide in contact with the filter screen.

[0013] As a preferred embodiment, the end of the second air guide tube is symmetrically and vertically provided with limiting grooves, and the surfaces of the insert rod and the first threaded rod are symmetrically fixedly installed with limiting rods, and multiple limiting rods are respectively slidably and sealingly arranged in multiple limiting grooves.

[0014] As a preferred embodiment, the surface of the mounting ring is symmetrically fixedly mounted with second threaded rods. One end of the hollow rod is closed and has a round opening. A second mounting rod is rotatably mounted inside the round opening. One end of the second mounting rod has a second threaded groove. Two second threaded rods are respectively threaded into the two second threaded grooves. An arc-shaped baffle is fixedly mounted on the surface of the end of the second mounting rod located inside the hollow rod by a support rod. The surface of the baffle is in sliding sealing contact with the inner wall of the hollow rod. The baffle is used to alternately block the openings of the first air guide tube and the second air guide tube.

[0015] A method for assembling a prefabricated structure for pipelines in an underground integrated utility tunnel in an active crustal zone, the method comprising the following steps:

[0016] S1: First, bring the ends of the two water pipes to be assembled together and align the first flange with the first flange. Then rotate the water pipes so that the multiple threaded openings correspond to the positions of the multiple threaded fastening grooves.

[0017] S2: To install multiple bolts into multiple threaded openings and multiple threaded fastening grooves at multiple locations, multiple suction cups will correspond to the end positions of the multiple bolts respectively;

[0018] S3: Control multiple mounting plates to move towards the first flange until multiple suction cups are tightly pressed against the ends of multiple bolts. The suction cups will attract the bolts, thus restricting the bolts from rotating and completing the assembly of the water pipe.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. After the ends of the two water pipes are assembled by splicing the first flange, the second flange and multiple bolts, multiple suction cups can be controlled to tightly abut and attract the ends of the multiple bolts, thereby restricting the rotation of the bolts and preventing the bolts from rotating due to external vibration forces, which would cause the splicing assembly of the water pipe ends to loosen, thus improving the stability of the water pipe splicing assembly.

[0021] 2. When water flows through the water pipe, the reciprocating screw will rotate due to the force of the water flow. The gas in the two hollow tubes will enter the two first air guide tubes and press against the two corrugated tubes to stretch. If the suction of multiple suction cups fails, the two corrugated tubes will push the mounting ring to move when stretched, so that the multiple suction cups will again abut against and attract the ends of multiple bolts, improving the stability of the suction cups restricting the rotation of the bolts.

[0022] 3. The mounting ring will only move and reset when all suction cups fail. In other words, it is only necessary to push the mounting ring to move at this time. When the mounting ring does not move and reset, the opening of the first air guide tube will be covered by the baffle when the reciprocating screw rotates. As a result, the gas in the hollow tube will not enter the first air guide tube, and the bellows will not be stretched. At this time, the opening of the second air guide tube will be open, and the gas in the hollow tube will enter the second air guide tube and clean the filter screen to prevent the filter screen from being severely blocked, which would affect the water flow and improve the utilization rate of the gas in the hollow tube.

[0023] 4. The gas entering the two second air guide pipes will respectively drive the scraper to rotate and the multiple cleaning rods to move vertically. When the scraper rotates, it can clean the surface of the filter screen, and the multiple cleaning rods can clean multiple filter holes on the surface of the filter screen, which can strengthen the overall cleaning of the filter screen and improve the cleaning effect of the filter screen.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figures 1-13 An assembled structure for pipelines in an underground integrated pipe gallery in an active crustal zone includes a water pipe 1. A first flange 2 and a second flange 3 are fixedly sleeved at both ends of the water pipe 1. The surface of the first flange 2 has multiple threaded openings 4 in a circular shape. The surface of the second flange 3 has multiple threaded fastening grooves 5 in a circular shape. Bolts 6 are threaded into each of the multiple threaded openings 4. A branch pipe 27 is fixedly installed on the surface of the water pipe 1.

[0040] The surface of the first flange 2 is circumferentially fixed with multiple spring rods 7. One end of the spring rod 7 is fixedly fixed with a mounting plate 8. The surface of the mounting plate 8 has a through hole. A hollow rod 9 with a closed end is fixedly installed inside the through hole. A suction cup 10 is fixedly installed at the open end of the hollow rod 9. The multiple suction cups 10 correspond to the positions of multiple threaded ports 4.

[0041] When it is necessary to assemble the ends of multiple water pipes 1, firstly, the first flange 2 and the second flange 3 located at the ends of the water pipes 1 should be abutted together, and multiple threaded openings 4 should be aligned with the positions of multiple threaded fastening grooves 5 respectively. Then, multiple bolts 6 can be threaded into the corresponding threaded openings 4 and threaded grooves 5 respectively.

[0042] Then, control the retraction of multiple spring rods 7 so that multiple suction cups 10 are tightly pressed against the ends of multiple bolts 6. The suction cups 10 will deform under the pressure, and the gas inside the suction cups 10 will slip out from the gap between the contact surfaces of the suction cups 10 and the bolts 6. The suction cups 10 will attract the bolts 6, thereby limiting the rotation of the bolts 6 and preventing the bolts 6 from rotating due to external vibration. This will prevent the splicing assembly of the water pipe 1 from becoming loose and improve the stability of the splicing assembly of the water pipe 1.

[0043] The hollow rod 9 has a rotating opening at one closed end. A rotating rod 11 is installed inside the rotating opening in a sealed manner. A vent 12 is provided on the surface of the hollow rod 9. A sealing plate 13 for sealing the vent 12 is fixedly installed at the end of the rotating rod 11 located inside the hollow rod 9 via a connecting rod. A fixing block is fixedly installed at the end of the rotating rod 11 located outside the hollow rod 9. A torsion spring 14 is sleeved on the rotating rod 11. The two ends of the torsion spring 14 are fixedly connected to the fixing block and the hollow rod 9, respectively.

[0044] When it is necessary to release the suction cup 10, simply rotate the rotating rod 11 to control the rotation of the sealing plate 13 until the sealing plate 13 no longer covers the vent 12. At this time, the gas in the outside will enter the hollow rod 9 through the vent 12, thereby releasing the suction cup 10 from the bolt 6. When the rotating rod 11 is released, the rotating rod 11 will quickly rotate and reset the sealing plate 13 under the elastic potential energy of the torsion spring 14. The sealing plate 13 will cover the vent 12 again, keeping the vent 12 in a closed state.

[0045] Connecting rods 15 are fixedly mounted on the surface of mounting plate 8. Mounting rings 16 are fixedly mounted on the ends of multiple connecting rods 15 away from mounting plate 8. The mounting rings 16 are moved by a pressing assembly. The pressing assembly includes two hollow tubes 17 with one closed end, two piston rods 18 respectively slidably and sealed inside the two hollow tubes 17, two first air guide tubes 19, two corrugated tubes 20 with one closed end, and two pressing blocks 21 fixedly mounted on one end of the two corrugated tubes 20. Fixing rings 22 are symmetrically fixedly mounted on the surface of water pipe 1. The two hollow tubes 17 are respectively fixedly mounted inside the two fixing rings 22. The two first air guide tubes 19 are respectively fixedly mounted on the surface of the two hollow tubes 17. The two pressing blocks 21 abut against the mounting rings 16. The open ends of the two corrugated tubes 20 are respectively fixedly sleeved on the two first air guide tubes 19. At the pipe opening, the piston rod 18 is controlled to move laterally and reciprocally by a drive assembly. The drive assembly includes a rotating rod 41 horizontally rotatably installed inside the water pipe 1, a rotating blade 42 fixedly sleeved on the rotating rod 41, and a reciprocating screw 23 fixedly installed at one end of the rotating rod 41. A sliding plate 24 is threaded onto the reciprocating screw 23. A sliding opening is opened on the surface of the water pipe 1. One end of the sliding plate 24 extends out of the sliding opening, and arc-shaped rods 25 are fixedly installed on both the front and rear surfaces. The two arc-shaped rods 25 are fixedly connected to the two piston rods 18 respectively. A rotating ring is rotatably sleeved on the rotating rod 41. Straight rods are symmetrically fixedly installed on the surface of the rotating ring. One end of each of the two straight rods is fixedly connected to the inner wall of the water pipe 1. Sliding grooves are horizontally opened on the left and right walls of the sliding opening. Sealing plates 26 are fixedly installed on the left and right side walls of the sliding plate 24. The two sealing plates 26 are slidably and sealingly inserted into the two sliding grooves respectively.

[0046] When water flows in the water pipe 1, the rotating blade 42 is driven by the force of the water flow to rotate the rotating rod 41 and the reciprocating screw 23. At this time, the sliding plate 24 threaded onto the reciprocating screw 23 will move laterally back and forth with the two piston rods 18. When the piston rods 18 move into the hollow tube 17, the gas in the hollow tube 17 will enter the bellows 20 from the first air guide pipe 19, thereby pushing the bellows 20 to stretch. At this time, the two pressing blocks 21 located at the ends of the two bellows 20 will also move together toward the mounting ring 16.

[0047] When the mounting ring 16 moves, all the spring rods 7 will stretch together. When the suction of some of the suction cups 10 fails, the mounting ring 16 will not move and reset due to the elastic potential energy of the spring rods 7, since the suction of some of the suction cups 10 is still effective. Only when the suction of all the suction cups 10 fails will the mounting ring 16 move and reset. When some of the suction cups 10 fail, while others do not, the multiple suction cups 10 will still be at the ends of the multiple bolts 6, thus restricting the lateral movement of the bolts 6. When the bolts 6 cannot move, they still cannot rotate, that is, the restriction imposed on the bolts 6 by the suction cups 10 does not disappear.

[0048] If the suction of multiple suction cups 10 fails, the mounting ring 16 will move and reset, and will abut against the two pressing blocks 21 in the initial state. If the two bellows 20 are stretched, the two pressing blocks 21 will push the mounting ring 16 towards the bolt 6. The multiple suction cups 10 will again abut against the ends of the multiple bolts 6, thereby forming suction and improving the stability of the suction cups 10 in restricting the rotation of the bolts 6.

[0049] A filter screen 28 is fixedly installed inside the branch pipe 27. A second air guide pipe 29 is fixedly installed on the surface of the hollow pipe 17. One end of one of the second air guide pipes 29 is inserted into the water pipe 1, and a rod 30 is slidably inserted into the pipe opening. A mounting plate 31 is fixedly installed at the bottom end of the rod 30. The diameter of the mounting plate 31 is smaller than the diameter of the filter screen 28. Multiple cleaning rods 32 with tapered bottoms are fixedly installed on the surface of the mounting plate 31. The multiple cleaning rods 32 correspond to the positions of multiple filter holes on the surface of the filter screen 28. One end of another second air guide pipe 29 is inserted into the branch pipe 27, and a first threaded rod 33 is slidably inserted into the pipe opening. A second threaded rod 33 is rotatably installed at the center of the filter screen 28. A mounting rod 34 has a first threaded groove at one end, and a first threaded rod 33 is threaded into the first threaded groove. Scraper rods 35 are symmetrically fixedly mounted on the surface of the first mounting rod 34 and slide in contact with the filter screen 28. Limiting grooves 36 are symmetrically and vertically opened at the end of the second air guide tube 29. Limiting rods 37 are symmetrically fixedly mounted on the surfaces of the insertion rod 30 and the first threaded rod 33. Multiple limiting rods 37 are slidably and sealingly arranged in multiple limiting grooves 36. Under the restriction of multiple limiting rods 37 and multiple limiting grooves 36, the insertion rod 30 and the first threaded rod 33 can only move vertically within the second air guide tube 29 and will not rotate.

[0050] The surface of the mounting ring 16 is symmetrically fixed with second threaded rods 38. The hollow rod 9 has a round opening at one closed end, and a second mounting rod 39 is rotatably installed inside the round opening. One end of the second mounting rod 39 has a second threaded groove. The two second threaded rods 38 are respectively threaded into the two second threaded grooves. At the end of the second mounting rod 39 located inside the hollow rod 9, an arc-shaped baffle 40 is fixedly installed on the surface by a support rod. The surface of the baffle 40 slides and seals against the inner wall of the hollow rod 9. The baffle 40 is used to alternately block the openings of the first air guide tube 19 and the second air guide tube 29.

[0051] As the control mounting ring 16 moves, causing multiple suction cups 10 to abut and attract multiple bolts 6, the two second threaded rods 38 will also move together. Since the second threaded rods 38 cannot rotate, the second mounting rod 39 located at the end of the hollow tube 17 will rotate with the baffle 40 under the engagement of the threads. The baffle 40 will rotate to cover the opening of the first air guide tube 19, and at this time the opening of the second air guide tube 29 will be in the open state.

[0052] When the suction of multiple suction cups 10 fails, after the mounting ring 16 moves and resets, the second mounting rod 39 located at the end of the hollow tube 17 will rotate again with the baffle 40 under the engagement of the threads. The baffle 40 will rotate to cover the opening of the second air guide tube 29, while the opening of the first air guide tube 19 will be in the open state.

[0053] When the suction cups 10 adsorb onto the bolts 6 without failure, water flows in the water pipe 1, the reciprocating screw 23 rotates, and the slide plate 24 moves laterally back and forth with the piston rod 18. At this time, the gas in the two hollow tubes 17 will enter the two second air guides 29 respectively, but will not enter the first air guide 19 whose opening is covered. When the gas enters one of the second air guides 29, it will push the first threaded rod 33 to move vertically. At this time, with the cooperation of the threads, the first mounting rod 34 will rotate, thereby scraping off the impurities attached to the surface of the filter screen 28, achieving the effect of cleaning the surface of the filter screen 28. When the gas enters the other second air guide 29, it will push the insertion rod 30 to move vertically with the mounting plate 31. The multiple cleaning rods 32 will be inserted into the multiple filter holes on the surface of the filter screen 28 respectively, thereby cleaning the impurities blocked in the filter holes, strengthening the overall cleaning of the filter screen 28, and improving the cleaning effect of the filter screen 28.

[0054] When the suction cups 10 fail to adhere to the bolts 6, the opening of the second air pipe 29 will be closed, while the opening of the first air pipe 19 will be opened. When the piston rod 18 moves laterally, the gas in the hollow tube 17 will enter the first air pipe 19 instead of the second air pipe 29. The gas entering the first air pipe 19 will push the pressing block 21 to press the mounting ring 16, causing the suction cups 10 to abut and attract the bolts 6 again.

[0055] When the suction cups 10 do not completely fail to adhere to the bolts 6, the gas in the hollow tube 17 will not enter the first air guide tube 19 to do useless work when the piston rod 18 moves laterally back and forth. This is because there is no need to push the suction cups 10 to abut against the bolts 6. Instead, the gas will enter the second air guide tube 29 to clean the filter screen 28, thereby improving the utilization rate of the gas in the hollow tube 17.

[0056] A method for assembling a prefabricated structure for pipelines in an underground integrated utility tunnel in an active crustal zone, the method comprising the following steps:

[0057] S1: First, bring the ends of the two water pipes 1 to be assembled together and make the first flange 2 and the first flange 3 face each other. Then rotate the water pipe 1 so that the multiple threaded openings 4 correspond to the positions of the multiple threaded fastening grooves 5 respectively.

[0058] S2: If multiple bolts 6 are to be threaded into multiple threaded openings 4 and multiple threaded fastening grooves 5 respectively, then multiple suction cups 10 will correspond to the end positions of the multiple bolts 6 respectively.

[0059] S3: Control the multiple mounting plates 8 to move towards the first flange 2 until the multiple suction cups 10 are tightly abutted against the ends of the multiple bolts 6. The suction cups 10 will attract the bolts 6, thereby restricting the rotation of the bolts 6 and completing the assembly of the water pipe 1.

[0060] In this invention, when assembling the ends of multiple water pipes 1, the first flange 2 and the second flange 3 located at the ends of the water pipes 1 are first brought together, and the multiple threaded openings 4 are aligned with the positions of the multiple threaded fastening grooves 5. Then, multiple bolts 6 are threaded into the corresponding threaded openings 4 and threaded grooves 5. Then, the multiple spring rods 7 are controlled to retract, so that the multiple suction cups 10 are tightly pressed against the ends of the multiple bolts 6. The suction cups 10 will deform under the pressure, and the gas inside the suction cups 10 will slip out from the gap between the contact surfaces of the suction cups 10 and the bolts 6. The suction cups 10 will attract the bolts 6, thereby limiting the rotation of the bolts 6 and preventing the bolts 6 from rotating due to external vibration. This would prevent the splicing assembly of the ends of the water pipes 1 from becoming loose, thus improving the stability of the splicing assembly of the water pipes 1.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
