Description

Technical Field

[0001] The present invention relates to the field of utility tunnels, and particularly to a prefabricated waterproof underground utility tunnel. Background Art

[0002] A prefabricated waterproof underground utility tunnel is a modern urban infrastructure that can integrate various pipelines such as power, communication, water supply, and drainage. Using prefabricated component technology, the main body of the utility tunnel is fabricated in a factory and then transported to the site for assembly to form an underground passage utility tunnel system with waterproof function; The Chinese patent with the publication number "CN113737856A" discloses "an underground utility tunnel, including an outer side wall (1), in which an upper horizontal partition (2) and a lower horizontal partition (3) are arranged at intervals up and down, and a smoke exhaust and ventilation passage (4) is formed between the upper part of the outer side wall (1) and the upper horizontal partition (2)". Although it can achieve the effect of "the underground utility tunnel not only ensures the functions of urban traffic and municipal utility tunnels, but also can reduce energy waste, achieving the purposes of intensive design, environmental protection, and three-dimensional utilization of underground space", when the underground utility tunnel is in use, the utility tunnel has a fixed integral structure. After the utility tunnel is installed underground, its angle cannot be adjusted. It is necessary to adjust the parallel angle by hoisting during laying and then dock multiple utility tunnels. Therefore, the angle adjustment during laying and docking is troublesome. Moreover, the fixed structure of the utility tunnel is easily damaged when impacted and cannot maintain a stable state. At the same time, when water leaks in the utility tunnel, the water cannot be discharged in time, resulting in water accumulation in the utility tunnel and making it impossible to be used safely. After the utility tunnel is buried underground, it is also easily affected by long-term humidity, which accelerates the corrosion of metal components in the utility tunnel, thereby reducing the service life of the utility tunnel.

A plurality of steel pipe through holes 16 are opened on the pipe wall of the connecting steel pipe 15, and the steel pipe through holes 16 play the role of guiding water and air.

[0025] In this embodiment, the outer wall of the pipe gallery main body 1 is attached to the connecting steel pipe 15. The connecting steel pipe 15 rotates in cooperation with the rotation of the pipe gallery main body 1. The steel pipe through hole 16 penetrates the pipe wall of the connecting steel pipe 15. A drain pipe 24 is provided at the rear bottom of the end plate 23. A drain outlet 25 is welded to the rear end of the drain pipe 24. The front end of the drain pipe 24 is fixedly connected to the rear end of the lower connecting steel pipe 15. The water in the connecting steel pipe 15 flows into the drain pipe 24 and is discharged from the drain outlet 25.

[0026] In this embodiment, the air delivery structure 26 includes an annular pipe 27, an air delivery pipe 28, and a blower 29. The annular pipe 27 is located at the rear top of the end plate 23. The air delivery pipe 28 is fixedly installed at the lower end of the annular pipe 27. The blower 29 is fixedly installed at the front end of the air delivery pipe 28.

[0027] In this embodiment, the annular pipe 27 is fixedly connected to the rear ends of the connecting steel pipes 15 on both sides. The annular pipe 27 is located above the drain pipe 24. The blower 29 inputs air into the connecting steel pipe 15 through the air delivery pipe 28 and the annular pipe 27.

[0028] It should be noted that the present invention is a prefabricated waterproof underground pipe gallery. When in use, the pipe gallery main body 1 and the pipe gallery shell 12 are prefabricated, and then the pipe gallery main body 1 and the pipe gallery shell 12 are buried underground, and a plurality of pipe gallery main bodies 1 and pipe gallery shells 12 are docked to form an underground pipe gallery passage. The sewage pipe bin 2 is used for laying sewage pipes, the heat storage bin 3 is used for laying heat transmission pipes, the electric power bin plate 6 is used for erecting electric power lines. At the same time, the inside of the pipe gallery main body 1 can be walked by operators, so that the pipes and lines are laid underground and have the effect of sealing and waterproofing; When the main body 1 of the pipe gallery is being built, the retracting and releasing knob 19 is rotated to drive the retracting and releasing wheel 18 to rotate, so that the retracting and releasing wheel 18 retracts and releases the retracting and releasing steel rope 20. Then, the retracting and releasing steel rope 20 pulls one end of the rotating clamping groove 7 through the buffer structure 8, thereby pulling the main body 1 of the pipe gallery to rotate, so that the main body 1 of the pipe gallery rotates on the connecting steel pipe 15, while the pipe gallery shell 12 remains stationary. Then, the retracting and releasing wheel 18 is positioned, thereby changing the parallel angle of the main body 1 of the pipe gallery; When the main body 1 of the pipe gallery is in long-term use, the impact received will be transmitted to the main body 1 of the pipe gallery. The main body 1 of the pipe gallery rotates and swings on the connecting steel pipe 15 inside the pipe gallery shell 12. At the same time, the retracting and releasing steel ropes 20 on both sides of the top pull the stretching connecting frame 11. Then, the stretching connecting frame 11 pulls the shock-absorbing spring 10 and the damping shock absorber 9 to contract, so as to use the contraction of the shock-absorbing spring 10 and the damping shock absorber 9 to achieve the swing buffering of the main body 1 of the pipe gallery and keep the main body 1 of the pipe gallery in a stable state; When water leaks in the sewage pipe bin 2 and the heating bin 3, the water level rises above the water discharge hole 30 and flows in from its interior, and then flows into the water guide hole 31 and moves downward, and is discharged between the main body 1 of the pipe gallery and the pipe gallery shell 12. Then, the water contacts the connecting steel pipe 15 and seeps into it through the steel pipe through hole 16 on the connecting steel pipe 15. Therefore, the leaked water is drained along the connecting steel pipe 15 to the end and discharged from the water discharge port 25 on the drain pipe 24, realizing the diversion and discharge of the leaked water; When the humidity of the air in contact with the main body 1 of the pipe gallery is too high, the air blower 29 conveys dry air to the air supply pipeline 28 and the annular pipeline 27, so that the air enters the multiple connecting steel pipes 15 on both sides. Then, the air is discharged along the steel pipe through hole 16 on the connecting steel pipe 15 and enters between the pipe gallery shell 12 and the main body 1 of the pipe gallery, realizing the ventilation between the pipe gallery shell 12 and the main body 1 of the pipe gallery and maintaining the drying requirement of the main body 1 of the pipe gallery.
