Description

Technical Field

[0001] This invention relates to the field of utility tunnel technology, and in particular to a multi-compartment assembled integrated utility tunnel joint. Background Technology

[0002] With rapid socio-economic development, expanding urban areas, and increasing populations, the demand for basic necessities such as water, electricity, communications, and gas is constantly growing. Existing municipal pipelines, including water supply and drainage pipes, electrical wires, heating pipes, and gas pipes, are being expanded, renovated, or newly constructed. This results in repeated road excavation, a significant waste of manpower and resources, and the tangled network of old and new pipelines negatively impacts the city's aesthetics and image. Therefore, more and more cities are constructing underground utility tunnels. This not only solves the problem of "road zipper" issues and the "spider web" phenomenon (referring to the dense network of overhead wires), but also facilitates the expansion, maintenance, protection, and extension of underground pipelines, thereby achieving full utilization and sustainable development of underground space.

[0003] Single-segment utility tunnels are assembled into a complete underground utility tunnel through longitudinal joints. After the prefabricated and assembled utility tunnel segments are installed in place, there are a large number of joints between the segments. These joints are weak points in the overall structure of the utility tunnel. Uneven settlement of the foundation will cause differential settlement of the segments, which will lead to deformation or even damage of the joints. Since the joints are an integral part of the utility tunnel structure, they cannot be replaced, which may cause water leakage in the utility tunnel, affect the safety of internal pipelines, and reduce the service life of the utility tunnel. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 11 A multi-compartment assembled integrated utility tunnel joint includes a utility tunnel body 10, one end of which is provided with a spigot end 101 and the other end with a socket end 102; it also includes:

[0026] The central wall 2 is located inside the main body 10 of the pipe gallery. One end of the central wall 2 is provided with a plurality of connecting keys 201 and the other end is provided with a plurality of connecting nests 202.

[0027] A sealing device is used to seal the joint between the two main pipe gallery bodies 10. In this invention, the connecting key 201 on the central wall 2 inside the main pipe gallery body 10 is connected to the connecting socket 202, and the spigot end 101 on the main pipe gallery body 10 is connected to the socket end 102. Together, these improve the connection effect of the pipe gallery. When the foundation settles unevenly, the pipe gallery segments are less likely to settle. The sealing device is used to seal the joint between the two main pipe gallery bodies 10 to prevent water leakage from the pipe gallery and affect the safety of the internal pipelines.

[0028] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0029] In this embodiment, the sealing device includes a sealing frame 3, a cover plate 4, an upper pressure plate 5, a lower pressure plate 6, two L-shaped side pressure plates 7, and two connecting devices. The sealing frame 3 is provided with a first cavity 301, and the cover plate 4 is provided with a second cavity 401. The upper pressure plate 5 is disposed in the second cavity 401, and the lower pressure plate 6 and the two side pressure plates 7 are disposed in the first cavity 301. The side pressure plates 7 are provided with through holes 701, and one end of the lower pressure plate 6 is disposed in the through hole 701. The connecting devices are used to connect the sealing frame 3 and the cover plate 4. After the two main pipe racks 10 are joined, cement is filled into the first cavity 301 of the sealing frame 3, and the sealing frame 3 is installed at the joint of the two main pipe racks 10. Then, cement is filled into the second cavity 401 of the cover plate 4, and the cover plate 4 is installed on the sealing frame 3. The cement will adhere to the outer wall of the main pipe rack 10, thereby sealing the joint of the two main pipe racks 10. The connecting device connects the sealing frame 3 and the cover plate 4 together to form a whole, which protects the cement. At the same time, when the foundation settles unevenly, the cooperation between the sealing frame 3 and the cover plate 4 can also provide support for the main pipe rack 10.

[0030] In this embodiment, the sealing frame 3 has a first through hole 302 and a plurality of through grooves 303 on both sides, and the cover plate 4 has a second through hole on both sides; the connecting device includes a connecting plate 8 and a plurality of round rods 9, sliding sleeves 11 and stop rods 12, the round rods 9 are disposed on the connecting plate 8, and the sliding sleeves 11 are sleeved on a portion of the round rods 9. The round rods 9 are provided with limiting blocks 901, the sliding sleeves 11 are provided with sliding grooves 111 and clearance grooves 112, and the stop rods 12 are disposed on the sliding sleeves 11. Part of the round rod 9 is provided with a sliding sleeve 11, and the sliding groove 111 cooperates with the limiting block 901. One end of the sliding sleeve 11 extends out of one end of the round rod 9. When the connecting plate 8 is installed, the round rod 9 at the bottom of the connecting plate 8 passes through the second through hole, and the round rod 9 at the bottom of the connecting plate 8 passes through the first through hole 302. The remaining round rods 9 and the stop rods 12 on them pass through the through groove 303. When one end of the sliding sleeve 11 contacts the side pressure plate 7, the side pressure plate 7 is pushed to the left, and the limiting block 901 disengages from the sliding groove 111 and enters the clearance groove 112. The sliding sleeve 11 will rotate on the round rod 9, so that the longer end of the stop rod 12 faces down, so that the round rod 9 cannot disengage from the through groove 303, thus achieving the function of fixing the connecting plate 8.

[0031] In this embodiment, both the upper pressure plate 5 and the lower pressure plate 6 have inclined surfaces at their ends. When one end of the sliding sleeve 11 contacts the side pressure plate 7, the side pressure plate 7 is pushed to the left, and the round rod 9 continues to move to the right, thereby pushing the upper pressure plate 5, the lower pressure plate 6, and the side pressure plate 7 to move. The movement of the upper pressure plate 5 will squeeze the cement in the second cavity 401, and the movement of the lower pressure plate 6 and the side pressure plate 7 will squeeze the cement in the first cavity 301, so that there will be no gap between the cement and the outer wall of the pipe gallery body 10, achieving a better sealing effect.

[0032] In this embodiment, the upper pressure plate 5 is provided with a protrusion 501. This creates a gap between the upper pressure plate 5 and the inner wall of the second cavity 401, facilitating the insertion of the round rod 9.
