Description

Technical Field

[0001] The technical field of this utility model specifically relates to an integrated utility tunnel intersection node and a road structure including therewith. Background Technology

[0002] For integrated utility tunnels with dual or multi-compartment drainage chambers, the construction process for their intersections is very complex. Existing technologies often employ either overall submersion or partial inverted siphon methods. Overall submersion allows the drainage chamber to maintain a continuous slope at a lower position, avoiding conflicts with other pipelines at intersections, allowing water flow to pass smoothly through the intersection naturally under gravity. Partial inverted siphon methods are suitable for situations where pipeline connection issues cannot be resolved through overall submersion or other methods. By installing inverted siphon pipes, the siphon principle is used to allow water flow to pass smoothly through the intersection. However, overall submersion increases the tunnel's burial depth, requires local lifting equipment for the drainage chamber, and increases civil engineering and maintenance costs. Partial inverted siphon methods result in poorer hydraulic conditions in the drainage chamber section, increased dredging and maintenance costs, and poor pipeline sealing.

[0003] Invention patent CN108824479B discloses a cross node for a double-compartment integrated utility tunnel with drainage compartments. Near the intersection of two integrated utility tunnels, the drainage compartment of the second integrated utility tunnel is offset from the integrated compartment of the second integrated utility tunnel. The drainage compartment of the second integrated utility tunnel is connected to the drainage compartment of the first integrated utility tunnel via a drainage compartment connecting section. The integrated compartment of the first integrated utility tunnel has an underpass section to avoid the drainage compartment connecting section. At the intersection of the two integrated utility tunnels, the integrated compartment of the second integrated utility tunnel also has an underpass section to avoid the integrated compartment of the first integrated utility tunnel, thus forming a double-crossing, double-layer integrated utility tunnel cross node, avoiding the three-layer utility tunnel cross node form and reducing the foundation pit depth. However, due to the large planar area occupied by this cross node and the poor predictability of the drainage compartment offset distance and connection point location, this invention is difficult to adapt to the development needs of multi-compartment utility tunnels to form a ring in the later stages. Utility Model Content

[0004] The purpose of this utility model is to provide a cross node of an integrated utility tunnel and a road structure including it, which can set a transition structure at the cross node based on the existing layout of the integrated utility tunnel, and reserve connection ports to maximize land use, ensure smooth connection of drainage chambers, and meet the needs of long-term development of integrated utility tunnels.

[0005] To achieve the above objectives, this application provides a cross node for integrated utility tunnels, including: a first integrated utility tunnel and a second integrated utility tunnel arranged in a cross manner, wherein the first integrated utility tunnel includes a first drainage chamber and a first integrated chamber, and the second integrated utility tunnel includes a second drainage chamber and a second integrated chamber.

[0006] The first drainage chamber extends along a first straight line, and the shape of any cross-section of the first drainage chamber is the same rectangle. The first integrated chamber includes an overlapping section and an offset section, a first descending section, and a first main body section symmetrically arranged at both ends of the overlapping section and connected in sequence. The shape of the cross-section of each part of the first integrated chamber is the same rectangle. The first main body section is arranged in parallel on one side of the first drainage chamber. The first descending section gradually slopes downward from one end close to the first main body section to the other end. The top surface of the first descending section away from the first main body section is flush with the bottom surface of the first drainage chamber. The offset section is located on one side of the first drainage chamber and below it. The offset section gradually deflects to the other side of the first drainage chamber from one end close to the first descending section to the other end. The overlapping section is fitted to the bottom of the first drainage chamber. A first connection port is opened on the side of the overlapping section. A second connection port is opened on the side of the first drainage chamber above the first connection port.

[0007] The second drainage chamber extends along the second straight line, and the cross-sectional shape of each part of the second drainage chamber is the same rectangle. The second integrated chamber includes a horizontal section and a second descending section and a second main body section symmetrically arranged at both ends of the horizontal section and connected in sequence. The cross-sectional shape of each part of the second integrated chamber is the same rectangle. The second main body section is arranged in parallel on one side of the first drainage chamber. The second descending section gradually slopes downward from one end near the second main body section to the other end. The top surface of the second descending section away from the second main body section is flush with the bottom surface of the first drainage chamber. The horizontal section is located below the second drainage chamber, and the top surface of the horizontal section is flush with the top surface of the overlapping section.

[0008] The first straight line direction intersects with the second straight line direction.

[0009] As a preferred technical solution, the height of the first drainage tank and the first integrated tank is H1, the height of the second drainage tank and the second integrated tank is H2, H1≥H2, the descent height of the first descent segment is H3, the descent height of the second descent segment is H4, and H3=H4=H1.

[0010] As a preferred technical solution, the overlapping segment includes a through segment and standard segments symmetrically disposed at both ends of the through segment. The other end of the standard segment is connected to the offset segment, and the cross-sectional area of ​​the through segment is larger than the cross-sectional area of ​​the standard segment.

[0011] As a preferred technical solution, the cross-sectional width of the through section is 1.3 times the cross-sectional width of the standard section.

[0012] As a preferred technical solution, the inclination slope of the first descent segment and the second descent segment does not exceed 10°.

[0013] As a preferred technical solution, the deflection angle of the offset segment does not exceed 30°.

[0014] This application also provides a road structure, including a ventilation shaft, a ventilation pavilion, and an integrated utility tunnel intersection node as described above. The ventilation shaft is located on top of the first drainage chamber and communicates with the interior of the first drainage chamber. The top surface of the ventilation shaft protrudes above the ground, and the ventilation pavilion is connected to the top of the ventilation shaft.

[0015] This application also provides another road structure, including a mezzanine, a ladder, multiple manholes, and the integrated utility tunnel intersection node as described above. The mezzanine is located on top of the first drainage chamber, and an escape hatch is provided on the top of the mezzanine. The ladder is located on the inner wall of the mezzanine, and the multiple manholes are respectively located at the connection between the first integrated chamber and the first drainage chamber, and at the connection between the first drainage chamber and the mezzanine.

[0016] The advantages of the integrated utility tunnel intersection node provided by the above technical solution compared with the existing technology are as follows:

[0017] 1. By configuring the first integrated compartment as an overlapping section and symmetrically located at both ends of the overlapping section and connected sequentially, along with an offset section, a first descending section, and a first main body section, it can sink and offset to the bottom of the first drainage compartment. Connection ports are provided on the same side of the overlapping sections. The second integrated compartment is configured as a horizontal section and symmetrically located at both ends of the horizontal section and connected sequentially, along with a second descending section and a second main body section, allowing it to sink to the lower side of the second drainage compartment and be flush with the overlapping section. This allows the second drainage compartment to communicate with the first drainage compartment through the connection ports on the first drainage compartment, and the second integrated compartment to communicate with it through the connection ports on the second integrated compartment. The structure is simple, and the burial depth is only increased at the overlapping section, first descending section, and first offset section of the first integrated compartment and the horizontal section and second descending section of the second integrated compartment, without increasing the overall burial depth of the first and second integrated compartments, effectively saving land. Furthermore, the connection ports ensure smooth connection between the various drainage compartments and the integrated compartment.

[0018] 2. The location of the connection point can be flexibly set in the overlapping section to adapt to the different locations of the drainage compartment and the integrated compartment, which is conducive to meeting the needs of the long-term development of the integrated utility tunnel.

For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] Please see Figure 1-6 The present application provides a cross node of a utility tunnel, comprising: a first utility tunnel and a second utility tunnel arranged in a cross manner, wherein the first utility tunnel includes a first drainage chamber 1 and a first integrated chamber 2, and the second utility tunnel includes a second drainage chamber 3 and a second integrated chamber 4.

[0036] The first drainage chamber 1 extends along a first straight line, and the shape of any cross section of the first drainage chamber 1 is the same rectangle. The first integrated chamber 2 includes an overlapping section 22 and an offset section 24, a first descending section 23, and a first main body section 25 symmetrically arranged at both ends of the overlapping section 22 and connected in sequence. The shape of the cross section of the first integrated chamber 2 is the same rectangle. The first main body section 25 is arranged in parallel on one side of the first drainage chamber 1. The first descending section 23 gradually slopes downward from one end close to the first main body section 25 to the other end. The top surface of the first descending section 23 away from the first main body section 25 is flush with the bottom surface of the first drainage chamber 1. The offset section 24 is located on one side of the first drainage chamber 1 and below it. The offset section 24 gradually deflects to the other side of the first drainage chamber 1 from one end close to the first descending section 23 to the other end. The overlapping section 22 is attached to the bottom of the first drainage chamber 1. A first connection port 11 is opened on the side of the overlapping section 22. A second connection port 21 is opened on the side of the first drainage chamber 1 above the first connection port 11.

[0037] The second drainage chamber 3 extends along the second straight line direction, and the cross-sectional shape of each part of the second drainage chamber 3 is the same rectangle. The second integrated chamber 4 includes a horizontal section 43 and a second descending section 42 and a second main body section 41 symmetrically arranged at both ends of the horizontal section 43 and connected in sequence. The cross-sectional shape of each part of the second integrated chamber 4 is the same rectangle. The second main body section 41 is arranged in parallel on one side of the first drainage chamber 1. The second descending section 42 gradually slopes downward from one end close to the second main body section 41 to the other end. The top surface of the second descending section 42 away from the second main body section 41 is flush with the bottom surface of the first drainage chamber 1. The horizontal section 43 is located below the second drainage chamber 3. The top surface of the horizontal section 43 is flush with the top surface of the overlapping section 22.

[0038] The first straight line direction intersects with the second straight line direction.

[0039] In this embodiment, after passing through the first descending section 23, the first integrated compartment 2 is positioned below the side of the first drainage compartment 1. Then, after passing through the offset section 24, it deflects to the other side of the first drainage compartment 1 at a certain angle, so that the overlapping section 22 connected to the offset section 24 is located exactly below the first drainage compartment 1 and fits against the bottom of the first drainage compartment 1. Connection ports are respectively opened on one side of the fitting area between the two compartments. After passing through the second descending section 42, the second integrated compartment 4 is positioned below the side of the second drainage compartment 3, and the horizontal section 43 and the overlapping section 22 are at the same height. Finally, the first and second integrated compartments 4 are connected through the first connection port 11, and the first and second drainage compartments 3 are connected through the second connection port 21. The burial depth of the main sections of the two integrated compartments was not increased; only the burial depth of other parts was increased. Furthermore, the descent distance of the descending section and the offset distance of the offset section 24 can be adjusted by adjusting the tilt slope and offset angle, further reducing the increase in burial depth and effectively reducing the land area required. In addition, by setting up connection ports, each drainage compartment and each integrated compartment can be connected in a one-to-one correspondence, ensuring smooth connection between the compartments. Moreover, when the location distribution of the drainage compartments and integrated compartments changes, this scheme can still achieve one-to-one connection between the compartments. Multiple connection ports can be set at the position where the first drainage compartment 1 and the overlapping section 22 fit together, as well as at the overlapping section 22, to connect more pipelines, which is conducive to adapting to the long-term development needs of the integrated utility tunnel.

[0040] Furthermore, the height of the first drainage chamber 1 and the first integrated chamber 2 is H1, the height of the second drainage chamber 3 and the second integrated chamber 4 is H2, H1 ≥ H2, the descent height of the first descending section 23 is H3, and the descent height of the second descending section 42 is H4, H3 = H4 = H1. According to the technical specifications for urban corridor engineering, the pipeline specifications of branch line pipe corridors should not be larger than those of trunk line pipe corridors. Therefore, the first integrated pipe corridor is located on the main line, and the second integrated pipe corridor is located on the branch line. Setting the descent height of the second descending section 42 to be the same as that of the first descending section 23 is to ensure that the second integrated chamber 4 can be connected to the first integrated chamber 2 through the first connection port 11 of the overlapping section 22.

[0041] Furthermore, the overlapping section 22 includes a through section 222 and standard sections 221 symmetrically arranged at both ends of the through section 222. The other end of the standard section 221 is connected to the offset section 24, and the cross-sectional area of ​​the through section 222 is larger than that of the standard section 221. On the one hand, this facilitates providing sufficient construction space when connecting the first and second drainage compartments 3 and the first and second integrated compartments 4; on the other hand, some pipelines in the pipe gallery may require additional inspection wells at the connection points, necessitating the reservation of certain space. It is worth noting that, in this embodiment, it is preferable to set the cross-sectional width of the through section 222 to 1.3 times the cross-sectional width of the standard section 221 to facilitate the subsequent connection construction of each compartment.

[0042] Furthermore, the inclination slope of the first descending section 23 and the second descending section 42 does not exceed 10°. The inclination slope does not exceed 10° for two reasons: firstly, to consider the overall structural stress of the integrated cabin and construction safety; and secondly, to comply with the provisions of the technical specifications for urban corridor engineering.

[0043] In addition, the setting of the deflection angle of the offset segment 24 to no more than 30° is a setting made for consideration of construction difficulty and safety. In other special cases, the angle can be adjusted adaptively according to the needs.

[0044] This application also provides a road structure, including a ventilation shaft 6, a ventilation pavilion 5, and the aforementioned integrated utility tunnel intersection node. The ventilation shaft 6 is located on top of the first drainage chamber 1 and communicates with the interior of the first drainage chamber 1. The top surface of the ventilation shaft 6 protrudes above the ground, and the ventilation pavilion 5 is connected to the top of the ventilation shaft 6. The ventilation shaft 6 and ventilation pavilion 5 can provide ventilation for the utility tunnel, serve as fire smoke exhaust channels, and also isolate and absorb noise generated by the operation of equipment within the utility tunnel to a certain extent, reducing the impact of noise on the surrounding environment and avoiding interference with nearby residents and buildings.

[0045] This application also provides another road structure, including a mezzanine 8, a ladder 9, multiple manholes 10, and the integrated utility tunnel intersection as described above. The mezzanine 8 is located on top of the first drainage chamber 1, and an escape hatch 7 is provided on the top of the mezzanine 8. The ladder 9 is located on the inner wall of the mezzanine 8. The multiple manholes 10 are respectively located at the connection between the first integrated chamber 2 and the first drainage chamber 1, and at the connection between the first drainage chamber 1 and the mezzanine 8. Combining the escape hatch 7, the mezzanine 8, and the integrated utility tunnel allows for a more compact and concentrated overall structural layout, reducing the land area required for separately setting up the escape hatch 7 and other facilities on the ground, improving the efficiency of land resource utilization, and also reducing construction costs and the impact on the surrounding environment. In addition to serving as an escape and ventilation passage, the mezzanine 8 can also be used for multiple functions according to actual needs, such as installing cable trays, communication lines, etc., to achieve comprehensive space utilization and improve the overall efficiency of the structure.

[0046] In summary, the integrated utility tunnel intersection node provided in this embodiment optimizes the layout of existing integrated utility tunnels, enabling the drainage compartments and integrated compartments of the main line to be connected one-to-one with the drainage compartments and integrated compartments of the branch line, maximizing land use efficiency and facilitating the further development of integrated utility tunnels.
