Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to an underground integrated pipe gallery structure. Background Technology

[0002] Underground utility tunnels are tunnel spaces built underground in cities to integrate various engineering pipelines such as water supply, electricity, communications, gas, and heating. They are equipped with dedicated inspection ports, hoisting ports, and escape routes. The service life of various engineering pipelines in underground utility tunnels is generally 20 years, while the design life of the main structure of the tunnel is at least 50 years. When the tunnel reaches a certain operating period, the engineering pipelines in the tunnel need to be replaced, so material feeding ports must be reserved. The size of the feeding port must be able to accommodate the largest diameter pipeline in the tunnel compartment, with a minimum width of not less than 1.5m, a maximum pipeline length of generally 6m, and a spacing between feeding ports generally not more than 400m.

[0003] A Chinese patent application with application number 201610212557.0 discloses a material inlet structure and construction method for an underground integrated utility tunnel. This structure includes a water supply pipe inlet, a cable inlet, a heavy-duty cover plate, a doorway, and equipment inlets / outlets. The water supply pipe inlet and cable inlet are connected through the doorway. The equipment inlets / outlets are located above and connected to the water supply pipe inlet. The heavy-duty cover plate is installed above the equipment inlets / outlets, which are connected to or separated from the road surface. This underground integrated utility tunnel material inlet structure has the following shortcomings: 1) The feeding port is covered by a heavy-duty cover plate, which requires manual opening and closing. The opening and closing operation is inconvenient, time-consuming and labor-intensive. 2) There is no hoisting mechanism inside, and pipeline replacement requires manual handling inside the underground utility tunnel, which is dangerous and inefficient.

[0004] Underground utility tunnels typically have a large number of material inlets. Due to their large size, these inlets are usually located in the green belts on both sides of the road and are generally below ground level. This often results in rainwater entering the utility tunnel through these inlets, affecting the main structure of the tunnel and the service life of pipelines and cables within it. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an underground integrated pipe gallery structure that is convenient to operate, saves time and effort, reduces the danger of manual handling, and improves work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An underground utility tunnel structure includes an underground utility tunnel body, with an external delivery port at the top of the underground utility tunnel body. The lower part of the underground utility tunnel body has multiple chambers, each of which has an internal delivery port at its top. The underground utility tunnel body has a connecting cavity above each internal delivery port. A hoisting mechanism is provided at the top of the connecting cavity. A staircase extending to the external delivery port is provided on the side wall of the connecting cavity. The external delivery port has an outer cover plate and an opening and closing drive mechanism for driving the opening and closing of the outer cover plate.

[0007] As a further improvement to the above technical solution: The external delivery port is surrounded by a frame, and one end of the outer cover plate is hinged to one side of the frame. The opening and closing drive mechanism includes a telescopic drive component, one end of which is hinged to the frame and the other end of which is hinged to the outer cover plate.

[0008] The telescopic drive component is a telescopic air cylinder, a telescopic hydraulic cylinder, or a telescopic electric cylinder.

[0009] The top surface of the external inlet is provided with a waterproof sealing gasket, and the frame is supported on the waterproof sealing gasket and fixed to the top surface of the external inlet by bolts.

[0010] The frame is equipped with a sealing ring, which is used to seal and press between the frame and the outer cover plate when the outer cover plate is closed.

[0011] Above the external discharge port is a pit connected to the ground, and the top of the pit is covered with a waterproof board.

[0012] A water-swellable waterproofing strip is provided between the waterproofing membrane and the ground layer, and hanging nails are provided on the waterproofing membrane.

[0013] Turf is placed on top of the waterproof liner.

[0014] The hoisting mechanism includes a hoisting rail and a movable seat. The hoisting rail is fixed to the top of the communicating cavity, and the movable seat is slidably mounted on the hoisting rail and is equipped with a lifting and hoisting assembly.

[0015] The inner inlet cover is equipped with an inner cover plate.

[0016] Compared with the prior art, the advantages of this utility model are: This utility model's underground integrated utility tunnel structure allows for pipeline replacement. First, the outer cover is opened via an opening / closing drive mechanism. Then, a hoisting mechanism is used to lift the old pipelines from the chamber and connecting chamber to below the external outlet. Next, the old pipelines are manually or using an external crane to lift them out. Then, the new pipelines are manually or using an external crane to lift them into the connecting chamber, and the hoisting mechanism is used to move the new pipelines to the desired location within the chamber or connecting chamber. After the pipeline replacement is complete, the outer cover is closed via the opening / closing drive mechanism. This underground integrated utility tunnel structure uses an opening / closing drive mechanism for operation, which is more convenient and saves time and effort compared to existing manual switches. Furthermore, a hoisting mechanism is provided at the top of the connecting chamber to assist in pipeline transfer, reducing the danger of manual handling and improving work efficiency.

The underground integrated utility tunnel structure of this embodiment includes an underground integrated utility tunnel body 1, an external delivery port 2 at the top of the underground integrated utility tunnel body 1, multiple chambers 3 at the bottom of the underground integrated utility tunnel body 1, an internal delivery port 4 at the top of each chamber 3, a connecting cavity 5 above each internal delivery port 4 on the underground integrated utility tunnel body 1, a hoisting mechanism 6 at the top of the connecting cavity 5, a staircase 7 extending to the external delivery port 2 on the side wall of the connecting cavity 5, and an external delivery port 2 having an external cover plate 8 and an opening and closing drive mechanism 9 for driving the opening and closing of the external cover plate 8.

[0026] When replacing pipelines in this underground utility tunnel structure, the outer cover plate 8 is first opened using the opening and closing drive mechanism 9. Then, the old pipelines in chamber 3 and connecting chamber 5 are hoisted to below the external outlet 2 using the hoisting mechanism 6. Next, the old pipelines are hoisted out manually or by an external crane. Then, the new pipelines are hoisted into connecting chamber 5 manually or by an external crane, and the new pipelines are then hoisted to the required location in chamber 3 or connecting chamber 5 using the hoisting mechanism 6. After the pipeline replacement is completed, the outer cover plate 8 is closed using the opening and closing drive mechanism 9. This underground utility tunnel structure uses the opening and closing drive mechanism 9 to drive the opening and closing, which is more convenient and saves time and effort compared to existing manual switches. Furthermore, the hoisting mechanism 6 is located at the top of connecting chamber 5 to assist in pipeline transportation, reducing the danger of manual handling and improving work efficiency.

[0027] Furthermore, such as Figure 2 and Figure 3As shown, in this embodiment, an outer frame 21 is provided outside the external inlet 2. One end of the outer cover plate 8 is hinged to one side of the frame 21. The opening and closing drive mechanism 9 includes a telescopic drive component 91, one end of which is hinged to the frame 21 and the other end to the outer cover plate 8. The telescopic drive component 91 moves telescopically, driving the outer cover plate 8 to rotate between the open and closed positions.

More preferably, a conventional on / off switch electrically connected to the telescopic drive component 91 can be provided in the communicating cavity 5, and the telescopic drive component 91 can be activated by pressing the on / off switch. Of course, the telescopic drive component 91 can also be controlled by an existing remote control switch, thereby controlling the opening and closing of the outer cover plate 8. Preferably, two telescopic drive components 91 are provided, located on the outer cover plate 8 and the frame 21 respectively.

[0028] Furthermore, in this embodiment, a waterproof sealing gasket 22 is provided on the top surface of the external inlet 2, and the frame 21 is supported on the waterproof sealing gasket 22 and fixed to the top surface of the external inlet 2 by bolts 23. On the one hand, the waterproof sealing gasket 22 improves the waterproof performance, and on the other hand, the bolts 23 make it easy to disassemble and assemble.

[0029] Furthermore, in this embodiment, a sealing ring 211 is provided on the frame 21, which is used to seal and press between the frame 21 and the outer cover plate 8 when the outer cover plate 8 is closed, thereby improving the sealing performance to prevent rainwater from passing through.

[0030] Furthermore, in this embodiment, a pit 24 connected to the ground is provided above the external outlet 2, and a waterproof membrane 25 is provided on the top of the pit 24. With the double effect of the waterproof membrane 25 and the outer cover plate 8, the performance of preventing external water from entering the underground integrated pipe gallery body 1 is further improved.

[0031] Furthermore, in this embodiment, a water-swellable waterstop strip 26 is provided between the waterproof membrane 25 and the ground layer to improve the waterproofing effect. The waterproof membrane 25 is provided with a lifting nail 251, which can be connected to external hoisting equipment to facilitate opening and closing of the waterproof membrane 25.
