[0002] As we all know, underground pipe gallery refers to the underground city pipeline integrated corridor. That is, a tunnel space is built underground in the city, which integrates various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, and is equipped with special inspection ports, lifting ports and monitoring systems. It implements unified planning, unified design, unified construction and management. It is an important infrastructure and "lifeline" to ensure the operation of the city.

[0003] The existing patent number is CN207331746U, which is an underground pipe gallery. The steel sheet piles used in this patent not only play the role of support and outer wall, but also have the functions of anti-floating and anti-compression. After the steel sheet piles exceed the depth of the bottom plate, the two sides of the steel sheet piles contact the soil at the same time, which increases the friction between the steel sheet piles and the soil, making the steel sheet piles more stable in the soil. The increase in friction between the steel sheet piles and the soil makes the steel sheet piles have the functions of both anti-pullout piles and support piles.

[0004] The inventors found in their daily work that although the above-mentioned underground pipeline corridor saves the materials and construction time of rebuilding the underground pipeline corridor and can effectively reduce the construction cost of the pipeline corridor, the above-mentioned underground pipeline corridor can only be formed by on-site casting, so the construction period is long, the construction workload is large, and the construction cost is still high.

A plug hole 410 is opened on the side of the splicing plate 402, and the end of the plug rod 409 away from the T-shaped plate 407 is plugged into the plug hole 410. The provision of the plug rod 409 and the plug hole 410 has the effect of limiting the splicing plate 402 inside the splicing seat 401.

[0030] In this embodiment: a limiting device 5 is provided on the top surface of the top plate 2, and the limiting device 5 includes a U-shaped plate 51, and the U-shaped plate 51 is fixedly installed on the top surface of the top plate 2. A threaded rod 52 is rotatably connected between the inner walls at both ends of the U-shaped plate 51, and a rotating wheel 53 is fixedly installed at one end of the threaded rod 52. When the use of the lifting ring 8 is finished, first rotate the rotating wheel 53, and the rotation of the rotating wheel 53 drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 drives the movable plate 55 to move inside the groove 54. The movement of the movable plate 55 inside the groove 54 drives the limiting rod 56 to move. The limiting rod 56 moves to move itself out of the limiting hole 57. The limiting rod 56 and the limiting hole 57 are separated to make the rotating shaft 7 lose the limit. At this time, the lifting ring 8 can be rotated to rotate the lifting ring 8 from the vertical state to the horizontal state. When the lifting ring 8 is in the horizontal state, reverse the rotating wheel 53 to make the limiting rod 56 reinsert into the corresponding limiting hole 57 to re-limit the rotation of the rotating shaft 7. Through the cooperation of the above structure, the use state of the lifting ring 8 can be adjusted, thereby avoiding the lifting ring 8 occupying too much installation and use area when the device is in use.

[0035] Working principle: by setting the assembly device 4, when it is necessary to assemble the top plate 2 and the bottom plate 1, first pull the pull rod 408, the movement of the pull rod 408 drives the T-plate 407 to move, the movement of the T-plate 407 drives the hinged plate 406 to move, the movement of the hinged plate 406 pulls the two slides 404 to move towards each other on the surface of the U-shaped rod 403, the two slides 404 move towards each other on the surface of the U-shaped rod 403, which squeezes the spring 405, so that the spring 405 is compressed, and at the same time, the movement of the T-plate 407 also drives the insertion rod 409 to move. When the insertion rod 409 moves to the appropriate position, the top plate 2 is hoisted to the top of the bottom plate 1 through the hoisting equipment and the lifting ring 8, and then the top plate 2 is slowly lowered so that the splicing plate 402 on the top inner wall surface of the top plate 2 is inserted into the splicing seat 401. Internally, when the splicing plate 402 and the splicing seat 401 are plugged in, the pull rod 408 is released, and the resilience of the spring 405 is used to reset the plug rod 409. The plug rod 409 is reset and then inserted into the inside of the socket 410. The plug rod 409 and the socket 410 are plugged in, so that the splicing plate 402 is firmly limited inside the splicing seat 401. The splicing plate 402 is firmly restricted inside the splicing seat 401, thereby completing the assembly operation between the top plate 2 and the bottom plate 1. Through the cooperation of the above-mentioned structure, the corridor is configured to be assembled by the bottom plate 1 unit and the top plate 2 unit, so that the prefabrication of the combined units of the underground corridor can be realized. The construction of the underground corridor can be realized by simply assembling the prefabricated finished product combined units at the construction site; therefore, the construction period can be shortened, the construction efficiency can be improved, and the construction cost of the entire corridor can be reduced. When the use of the lifting ring 8 is finished, first rotate the rotating wheel 53, and the rotation of the rotating wheel 53 drives the threaded rod 52 to rotate. The rotation of the threaded rod 52 drives the movable plate 55 to move inside the groove 54. The movement of the movable plate 55 inside the groove 54 drives the limiting rod 56 to move. The limiting rod 56 moves to move itself out of the limiting hole 57. The limiting rod 56 and the limiting hole 57 are separated to make the rotating shaft 7 lose the limit. At this time, the lifting ring 8 can be rotated to rotate the lifting ring 8 from the vertical state to the horizontal state. When the lifting ring 8 is in the horizontal state, reverse the rotating wheel 53 to make the limiting rod 56 reinsert into the corresponding limiting hole 57 to re-limit the rotation of the rotating shaft 7. Through the cooperation of the above structure, the use state of the lifting ring 8 can be adjusted, thereby avoiding the lifting ring 8 occupying too much installation and use area when the device is in use.
