Description

Technical Field

[0001] The utility model relates to the technical field of connection structures, in particular to a connection structure for a UHPC pipe gallery. Background Technique

[0002] Prefabricated and assembled utility tunnels have the advantages of improving project quality, improving the construction site environment, reducing construction workload, and shortening the construction period. The application of prefabricated assembly construction technology in construction projects has been relatively extensive. By 2025, the proportion of prefabricated buildings in newly built buildings in China will reach 30%. At present, the prefabricated and assembled technology is also being vigorously promoted in the field of utility tunnel engineering construction. The construction technology of prefabricated and assembled utility tunnels mainly includes various types such as integral segment type, segment assembly type, and assembled monolithic type. According to the publication number: CN211547811U, a prefabricated and assembled utility tunnel is disclosed, in which the first tunnel body and the second tunnel body are detachably connected, so that each part of the structure can be prefabricated and assembled in blocks. The material of the first tunnel body is ordinary concrete, and the material of the second tunnel body is UHPC. By using ordinary concrete material and UHPC material together to form a longitudinal integral structure, the anti-floating ability of the underground utility tunnel is effectively improved; since the first tunnel body is usually above the groundwater level, this can not only reduce the waterproof requirement of ordinary concrete, but also give full play to the excellent anti-seepage performance and anti-groundwater erosion performance of UHPC material, improving the durability of the tunnel structure; by prefabricating and assembling the utility tunnel in blocks, the transportation efficiency of the tunnel is improved, the weight of the utility tunnel segment can be greatly reduced, the requirement for hoisting equipment is reduced, and the durability of the tunnel structure is improved. However, the above technology still has some defects. For example, the existing tunnel is only connected by a groove and a block and then sealed with sealant during installation. It is not only time-consuming and laborious during splicing, but also the connection at the joint is likely to become loose after long-term use, and the practicability is poor, so it needs to be improved.

[0024] Embodiment 1

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a connection structure for a UHPC pipe gallery, including a pipe gallery body 1. A groove 2 is opened on the right side of the pipe gallery body 1, and a clamping block 3 is fixedly installed on the left side of the pipe gallery body 1. A supporting plate 4 is fixedly installed at the bottom end of the left side of the pipe gallery body 1. A baffle 5 is fixedly installed on the surface of the supporting plate 4, and a fixing block 6 is fixedly installed on the surface of the baffle 5. A rotating groove 7 is opened on the surface of the fixing block 6. A fixing groove 8 is opened on the surface of the pipe gallery body 1. A threaded rod 9 is rotatably connected inside the fixing groove 8. A turning handle 10 is fixedly installed on the back of the threaded rod 9. An installation groove 11 is opened inside the pipe gallery body 1. A clamping groove 12 is opened inside the installation groove 11. A clamping plate 13 is slidably connected inside the clamping groove 12. A sliding plate 14 is fixedly installed inside the clamping plate 13, and a protective cover 15 is fixedly installed on the surface of the sliding plate 14. By setting the supporting plate 4, the baffle 5, the fixing block 6, the rotating groove 7, the fixing groove 8, the threaded rod 9, the turning handle 10, the installation groove 11, the clamping groove 12, the clamping plate 13, the sliding plate 14 and the protective cover 15, a more convenient use effect is achieved. After splicing, the turning handle 10 can be pinched and rotated corresponding to the fixing groove 8, so that the threaded rod 9 rotates outwards inside the fixing block 6 through the rotating groove 7. When the threaded rod 9 is completely rotated into the fixing block 6, then the protective cover 15 can be pinched and the sliding plate 14 can be aligned with the installation groove 11 and pushed forward, so that the sliding plate 14 drives the clamping plate 13 to slide into the inside of the pipe gallery body 1 through the installation groove 11, and the clamping plate 13 firmly clamps the sliding plate 14 and the protective cover 15 inside the pipe gallery body 1 through the clamping groove 12, thus avoiding the situation that the existing pipe gallery is only connected through the groove 2 and the clamping block 3 and then sealed with sealant during installation. During splicing, it is not only time-consuming and laborious, but also the connection at the joint is likely to become loose after long-term use. The grooves 2 are evenly distributed on the right side of the pipe gallery body 1, and the clamping blocks 3 are evenly distributed on the left side of the pipe gallery body 1. The clamping blocks 3 are slidably connected with the grooves 2, which is more convenient for the clamping blocks 3 to slide and prevents the situation that the clamping blocks 3 cannot continue to slide due to being stuck by the pipe gallery body 1 during use. The baffles 5 are symmetrically distributed at the front and rear ends of the supporting plate 4. The threaded rod 9 is rotatably connected with the rotating groove 7, the threaded rod 9 is rotatably connected with the baffle 5, the threaded rod 9 is rotatably connected with the fixing block 6, and the threaded rod 9 is rotatably connected with the pipe gallery body 1, which is more convenient for the threaded rod 9 to rotate and avoids the situation that the threaded rod 9 cannot continue to rotate due to being stuck by the fixing block 6 or the pipe gallery body 1 during use. The turning handle 10 is rotatably connected with the installation groove 11 and the pipe gallery body 1, which is more convenient for the turning handle 10 to rotate and prevents the situation that the turning handle 10 cannot continue to rotate due to being stuck by the pipe gallery body 1 during use. The clamping plate 13 is slidably connected with the installation groove 11, the sliding plate 14 is slidably connected with the installation groove 11, and the protective cover 15 is slidably connected with the pipe gallery body 1, which is more convenient for the clamping plate 13 to slide.Avoid the situation where the pallet 13 is stuck by the installation groove 11 during use, resulting in the pallet 13 being unable to slide further.

[0026] Embodiment 2

[0027] Please refer to Figures 1-3 As shown in FIGS. 6, a fixing rod 16 is fixedly installed at the top end of the pipe gallery body 1. The top end of the fixing rod 16 is fixedly installed with a fixing plate 17. A sliding block 18 is slidably connected to the top end of the fixing plate 17. A sliding groove 19 is formed inside the sliding block 18. A connecting rod 20 is fixedly installed at the top end of the sliding block 18. A lifting ring 21 is fixedly installed at the top end of the connecting rod 20, which is more convenient for the staff to carry with the help of a crane. When carrying is required, first align the sliding block 18 with the fixing plate 17 and push it inward, so that the sliding block 18 slides from the left side to the right side on the top end of the fixing plate 17 through the sliding groove 19. When the sliding block 18 completely slides on the top end of the fixing plate 17, it is okay. Then carry it through the lifting ring 21. And during the hoisting process, due to the different starting angles of the sliding groove 19, and during the hoisting, the lifting rope generates an inward and upward pulling force on the lifting ring 21, so that the situation where the sliding groove 19 slides out of the top end of the fixing plate 17 can be avoided during the hoisting process. The fixing rods 16 are symmetrically distributed at the left and right ends of the top end of the pipe gallery body 1. The sliding groove 19 is slidably connected with the fixing plate 17, and the sliding block 18 is slidably connected with the pipe gallery body 1, which is more convenient for the sliding block 18 to slide and avoid the situation where the sliding block 18 is stuck by the pipe gallery body 1 during use, resulting in the sliding block 18 being unable to slide further.

[0028] Working principle: When in use, first align the slider 18 with the upper fixing plate 17 through the chute 19 and pull it towards the middle of the pipe gallery body 1, so that the slider 18 slides from the right side to the left side of the fixing plate 17 through the chute 19. After the slider 18 completely slides to the top of the fixing plate 17 through the chute 19, then connect the lifting rope to the lifting ring 21. At this time, the lifting rope can be lifted upwards, and the pipe gallery body 1 can be lifted and transported through the connecting rod 20 and the fixing rod 16. During the lifting process, since the pulling force generated by the lifting rope is upward and inward, and because the slider 18 is installed on both sides of the fixing plate 17, this can avoid the situation that the slider 18 falls off the top of the fixing plate 17. When splicing, place the second pipe gallery body 1 between the top plate 4 and the baffle 5 on the left side of the first pipe gallery body 1, and then push it to the right, so that the second pipe gallery body 1 slides into the surface of the clamping block 3 of the first pipe gallery body 1 through the groove 2 and completes the splicing. At this time, hold the rotating handle 10 and rotate the threaded rod 9 corresponding to the fixing groove 8, so that the threaded rod 9 rotates outward through the rotating groove 7 inside the fixing block 6. When the threaded rod 9 completely rotates into the inside of the fixing block 6 through the rotating groove 7, and at this time the rotating handle 10 rotates into the inside of the pipe gallery body 1 through the installation groove 11, then hold the protective cover 15 corresponding to the installation groove 11 and push it inward, so that the sliding plate 14 drives the clamping plate 13 to slide forward through the installation groove 11 inside the pipe gallery body 1. When the clamping plate 13 slides into the inside of the clamping groove 12, the protective cover 15 can be firmly clamped inside the pipe gallery body 1 through the sliding plate 14, thus achieving the effect of protecting the rotating handle 10.

[0029] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
