Description

Technical Field

[0001] This utility model relates to the field of municipal infrastructure construction technology, and more specifically, to a multi-functional node for a multi-compartment underground integrated pipe gallery. Background Technology

[0002] Underground utility tunnels are used to house a city's underground pipelines. They can integrate various underground pipelines into a single tunnel, facilitating maintenance and repair. This enables intensive use of urban land, improves the city's disaster prevention and mitigation capabilities, and is an important component of modern cities.

[0003] Since each type of underground pipeline requires corresponding auxiliary equipment such as ventilation or power distribution, it places a greater demand on the space of underground utility tunnels and increases the initial investment in underground utility tunnels. Utility Model Content

[0004] The problem this utility model addresses is: how to reduce the space requirements of underground utility tunnels in order to reduce the initial investment in underground utility tunnels.

[0005] To address the aforementioned problems, this utility model provides a multi-compartment underground integrated utility tunnel multi-functional node, comprising an integrated utility tunnel layer, an equipment layer, and a ground layer, wherein the equipment layer is located between the integrated utility tunnel layer and the ground layer; the equipment layer includes multiple functional areas, which are independently separated; the integrated utility tunnel layer includes multiple functional utility tunnel compartments, which are independently separated and arranged side-by-side along the width of the integrated utility tunnel layer; the functional equipment installed in the functional areas corresponds to the functional utility tunnel compartments; the equipment layer is connected to the ground layer and the integrated utility tunnel layer respectively via fire ladders; the ground layer includes an escape passage exposed on the ground. Optionally, the integrated utility tunnel includes a fire-resistant partition wall that extends along the width of the integrated utility tunnel to divide it into two fire-resistant zones. The fire-resistant partition wall is equipped with fire doors, and each of the two fire-resistant zones is equipped with a fire ladder.

[0006] Optionally, the equipment layer further includes a lightweight fireproof cover plate, which corresponds to the location of the fire ladder. The lightweight fireproof cover plate has an open state and a closed state. When the lightweight fireproof cover plate is in the open state, it is used to connect the equipment layer and the integrated pipe gallery layer. When the lightweight fireproof cover plate is in the closed state, it is used to isolate the equipment layer and the integrated pipe gallery layer.

[0007] Optionally, the multiple functional areas include multiple exhaust zones, each exhaust zone is equipped with an exhaust device, the air inlet of the exhaust device is connected to the integrated pipe gallery layer, and the air outlet of the exhaust device is connected to the air outlet of the ground layer.

[0008] Optionally, the exhaust equipment includes a daily ventilation mode and a fire smoke exhaust mode. In the daily ventilation mode, the exhaust equipment is used to realize gas exchange within the integrated pipe gallery layer. In the fire smoke exhaust mode, the exhaust equipment is used to realize the rapid discharge of fire smoke.

[0009] Optionally, the multiple functional areas include an escape area, in which an escape ladder is provided, extending from the escape area to the exit of the escape passage.

[0010] Optionally, the plurality of functional areas may also include a power distribution area, in which a power distribution cabinet is installed.

[0011] Optionally, the power distribution area is connected to the adjacent ventilation area via a ventilation assembly.

[0012] Optionally, the exit of the escape passage is equipped with an escape hydraulic manhole cover.

[0013] Optionally, the air outlet of the ground layer is equipped with horizontal rainproof ventilation louvers.

[0014] Compared with related technologies, the multi-compartment underground integrated utility tunnel multi-functional node of this utility model achieves zoning of the integrated utility tunnel layer by including multiple functional utility tunnel compartments, which are independently separated and distributed side by side along the width of the integrated utility tunnel layer. This allows for the division of pipelines with different functions into different areas, not only achieving rational utilization of the integrated utility tunnel layer space but also facilitating targeted daily inspections. Furthermore, the equipment layer includes multiple functional areas, which are independently separated, and the functional equipment installed in each area corresponds to the functional utility tunnel compartments. The equipment layer can accommodate the centralized installation of all functional equipment required by the integrated utility tunnel layer, avoiding the occupation of space by functional equipment and achieving seamless integration of pipelines and functional equipment. The equipment is installed independently, allowing for centralized inspection of functional equipment on the equipment floor, improving inspection efficiency. The equipment floor is connected to the ground floor and the integrated utility tunnel floor via fire ladders. The ground floor includes exposed escape routes, allowing inspectors to travel between the integrated utility tunnel floor, equipment floor, and ground floor via fire ladders. The equipment floor, located between the integrated utility tunnel floor and the ground floor, achieves a vertical distribution of these three levels. The path to the ground floor is relatively short, reducing the time required for inspectors to reach the ground. This not only significantly reduces the time required for inspectors to escape to the ground but also achieves the rational utilization of multi-functional node spaces in the multi-compartment underground integrated utility tunnel, achieving the construction goals of economy, reliability, efficiency, and convenience.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0020] Combination Figures 1 to 7 As shown, this utility model embodiment provides a multi-compartment underground integrated utility tunnel multi-functional node, including an integrated utility tunnel layer 100, an equipment layer 200, and a ground layer 300. The equipment layer 200 is located between the integrated utility tunnel layer 100 and the ground layer 300. The equipment layer 200 includes multiple functional areas 210, which are independently separated. The integrated utility tunnel layer 100 includes multiple functional utility tunnel compartments 110, which are independently separated and arranged side by side along the width direction of the integrated utility tunnel layer 100. The functional equipment installed in the functional areas 210 corresponds to the functional utility tunnel compartments 110. The equipment layer 200 is connected to the ground layer 300 and the integrated utility tunnel layer 100 respectively through fire ladders 400. The ground layer 300 includes an escape passage 310 exposed on the ground. Specifically, the width direction of the integrated utility tunnel level 100 refers to the X-axis direction. Along the positive X-axis, the integrated utility tunnel level 100 is divided into four independent compartments, namely four functional utility tunnel compartments 110, such as... Figure 5 As shown, the structures are, in order, a thermal chamber, a general utility chamber, a low-pressure electrical chamber, and a high-pressure electrical chamber. The thermal chamber houses heating pipes and other equipment, while the general utility chamber houses sewage discharge pipes and other equipment. The thermal chamber, general utility chamber, low-pressure electrical chamber, and high-pressure electrical chamber are all independently separated. The equipment layer 200 is located above the general utility tunnel layer 100 and is divided into multiple independently separated functional areas 210. The necessary equipment is installed in each functional area 210, such as ventilation equipment required for the general utility tunnel layer 100 and electrical distribution cabinets for lighting. All necessary equipment is centrally installed within the equipment layer 200. Ladder openings are reserved at the top and bottom of the equipment floor 200, which connect the equipment floor 200 to the ground floor 300 and the integrated pipe gallery floor 100 respectively. The fire ladder 400 located at the bottom of the equipment floor 200 extends vertically downward to the bottom of the integrated pipe gallery floor 100, and the fire ladder 400 located at the top of the equipment floor 200 extends vertically upward to the bottom of the ground floor 300.

[0021] The multi-compartment underground utility tunnel multi-functional node in this embodiment is applicable to at least the following situations: Under normal operating conditions: After completing the inspection of the functional pipe gallery compartments 110 on the integrated pipe gallery level 100, the inspection personnel can reach the equipment level 200 from the fire ladder 400 of each functional pipe gallery compartment 110. Then, they can conduct daily inspections of the equipment in each functional area 210 on the equipment level 200. After the inspection, they can reach the ground level 300 from the equipment level 200 via the fire ladder 400, and then reach the ground from the escape passage 310 on the ground level 300.

[0022] In the event of a fire: When a fire occurs in the integrated utility tunnel 100, the ventilation equipment in the functional area 210 can quickly exhaust the smoke, while the multiple independent functional utility tunnels 110 can prevent the fire from spreading. The staff in the integrated utility tunnel 100 can quickly go to the equipment floor 200 via the fire ladder 400, and then go to the ground floor 300 via the fire ladder 400, and then go to the ground via the escape passage 310.

[0023] Therefore, in this embodiment, the integrated utility tunnel layer 100 includes multiple functional utility tunnel compartments 110, which are independently separated and arranged side-by-side along the width of the integrated utility tunnel layer 100, thus achieving the zoning of the integrated utility tunnel layer 100. This allows pipelines with different functions to be divided into different areas, not only achieving the rational utilization of the space of the integrated utility tunnel layer 100 but also facilitating targeted daily inspections. The equipment layer 200 includes multiple functional areas 210, which are independently separated, and the functional equipment installed in each functional area corresponds to the functional utility tunnel compartment 110. The equipment layer 200 can accommodate the centralized installation of all functional equipment required by the integrated utility tunnel layer 100, avoiding the occupation of space by functional equipment in the integrated utility tunnel layer 100. This allows for the independent installation of pipelines and functional equipment, enabling the functional equipment to be installed independently within the equipment layer 200. Centralized inspection of equipment improves inspection efficiency. Equipment level 200 is connected to ground level 300 and integrated utility tunnel level 100 via fire ladders 400. Ground level 300 includes an exposed escape route 310. Inspection personnel can use the fire ladders 400 to travel between integrated utility tunnel level 100, equipment level 200, and ground level 300. Equipment level 200 is located between integrated utility tunnel level 100 and ground level 300, achieving a vertical distribution of integrated utility tunnel level 100, equipment level 200, and ground level 300. The path for inspection personnel to reach ground level 300 is relatively short, reducing the time required for them to reach the ground. This not only significantly reduces the time for inspection personnel to escape to the ground but also achieves rational utilization of the multi-functional node space of the multi-compartment underground integrated utility tunnel, achieving the construction goals of economy, reliability, efficiency, and convenience.

[0024] Optionally, combined Figure 1 , Figures 5 to 7As shown, the integrated utility tunnel level 100 includes a fire-resistant partition wall 120, which extends along the width of the integrated utility tunnel level 100 to divide the integrated utility tunnel level 100 into two fire-resistant compartments 130. Fire doors 121 are installed on the fire-resistant partition wall 120. Fire ladders 400 are installed in each of the two fire-resistant compartments 130.

[0025] Specifically, the fire door 121 has a fire rating of Class A. The fire partition wall 120 extends along the width direction of the integrated utility tunnel 100, i.e., the X-axis direction. The fire partition wall 120 divides the integrated utility tunnel 100 into two fire compartments 130, front and rear. Fire doors 121 are installed on the fire partition wall 120. When the fire door 121 is opened, inspection personnel can travel between the two fire compartments 130. Each fire compartment 130 is equipped with a fire ladder 400, so that inspection personnel can reach the equipment floor 200 from the two fire compartments 130 via the fire ladder 400, whether in routine inspections or in the event of a fire.

[0026] Thus, by extending the fire-resistant partition wall 120 along the width of the integrated utility tunnel 100, the integrated utility tunnel 100 is divided into two fire-resistant zones 130. The fire-resistant partition wall 120 further improves the fire protection effect of the integrated utility tunnel 100, enabling the fire-resistant partition wall 120 to block fire and smoke in the event of a fire. Fire doors 121 are installed on the fire-resistant partition wall 120. Fire ladders 400 are installed in each of the two fire-resistant zones 130. The fire doors 121 facilitate the movement of inspection personnel between the two fire-resistant zones 130, and they can reach the equipment floor 200 above from either fire-resistant zone 130 via the fire ladders 400, meeting the needs of daily inspections while improving the effectiveness of underground fire protection.

[0027] Optionally, combined Figure 2 and Figure 5 As shown, the equipment layer 200 also includes a lightweight fireproof cover plate 220, which corresponds to the position of the fire ladder 400. The lightweight fireproof cover plate 220 has an open state and a closed state. When the lightweight fireproof cover plate 220 is in the open state, it is used to connect the equipment layer 200 and the integrated pipe gallery layer 100. When the lightweight fireproof cover plate 220 is in the closed state, it is used to isolate the equipment layer 200 and the integrated pipe gallery layer 100.

[0028] Specifically, the lightweight fireproof cover plate 220 is located inside the equipment floor 200 and covers the ladder opening at the bottom of the equipment floor 200. One end of the lightweight fireproof cover plate 220 is rotatably installed on the equipment floor 200 via a pivot. The lightweight fireproof cover plate 220 can rotate around the pivot axis and has an open state and a closed state. In the open state, the equipment floor 200 is connected to the integrated pipe gallery floor 100, allowing inspection personnel to travel between the equipment floor 200 and the integrated pipe gallery floor 100. In the closed state, the lightweight fireproof cover plate 220 covers the ladder opening, isolating the equipment floor 200 and the integrated pipe gallery floor 100. After climbing to the top of the fire ladder 400 in the integrated pipe gallery floor 100, inspection personnel can push the lightweight fireproof cover plate 220 upwards to open it.

[0029] Thus, by corresponding the lightweight fireproof cover plate 220 to the fire ladder 400, the lightweight fireproof cover plate 220 can play a fire-fighting role at each fire ladder 400. In the open state, the lightweight fireproof cover plate 220 connects the equipment floor 200 and the integrated pipe gallery floor 100. In the closed state, the lightweight fireproof cover plate 220 isolates the equipment floor 200 and the integrated pipe gallery floor 100. This not only facilitates the movement of inspection personnel between the equipment floor 200 and the integrated pipe gallery floor 100, but also prevents the spread of fire by closing the lightweight fireproof cover plate 220 in the event of a fire.

[0030] Optionally, combined Figure 2 , Figures 4 to 7 As shown, the multiple functional areas 210 include multiple exhaust areas 230. Each exhaust area 230 is equipped with an exhaust device 231. The air inlet of the exhaust device 231 is connected to the integrated pipe gallery layer 100, and the air outlet of the exhaust device 231 is connected to the air outlet of the ground layer 300.

[0031] Specifically, the equipment floor 200 is divided into multiple exhaust zones 230. Each exhaust zone 230 is separated by a fire-resistant partition wall 120. Each exhaust zone 230 is also equipped with a fire door 121 on the fire-resistant partition wall 120. Each exhaust zone 230 is equipped with an exhaust device 231. The air inlet of the exhaust device 231 is connected to the integrated pipe gallery floor 100, and the air outlet of the exhaust device 231 is connected to the air outlet of the ground floor 300.

[0032] Thus, by dividing the equipment layer 200 into multiple independent exhaust zones 230, and installing exhaust equipment 231 in each exhaust zone 230, the exhaust equipment 231 can be independently installed in the corresponding exhaust zone 230, achieving isolation of the exhaust equipment 231 to avoid a chain reaction of multiple exhaust equipment 231 in the event of a fire. The exhaust equipment 231 is connected to the integrated pipe gallery layer 100 through its air inlet end and to the air outlet of the ground layer 300 through its air outlet end. The exhaust equipment 231 can meet the daily ventilation and air exchange needs of the integrated pipe gallery layer 100, as well as the smoke exhaust needs during fire.

[0033] Optionally, the exhaust equipment 231 includes a daily ventilation mode and a fire smoke exhaust mode. In the daily ventilation mode, the exhaust equipment 231 is used to realize gas exchange within the integrated pipe gallery layer 100. In the fire smoke exhaust mode, the exhaust equipment 231 is used to realize the rapid discharge of fire smoke.

[0034] Specifically, the exhaust equipment 231 can be understood as a fan. The fan has two working modes: daily ventilation mode and fire smoke exhaust mode. In daily ventilation mode, the exhaust equipment 231 is used to realize gas exchange within the integrated pipe gallery layer 100. In fire smoke exhaust mode, the exhaust equipment 231 is used to realize the rapid discharge of fire smoke.

[0035] In this way, the exhaust equipment 231 is used to realize gas exchange in the integrated pipe gallery layer 100 in the daily ventilation mode, and to realize the rapid discharge of fire smoke in the fire smoke exhaust mode. The installation of a fan system with switching function in the equipment layer 200 integrates the functions of daily ventilation and fire smoke exhaust, reduces the number of equipment, reduces the area of ​​equipment rooms, effectively solves the problems of many equipment and large footprint caused by the independent installation of traditional solutions, and significantly reduces the project investment.

[0036] Optionally, combined Figure 2 and Figure 4 As shown, the equipment layer 200 includes an independently separated escape area 240, in which an escape ladder 241 is installed, extending from the escape area 240 to the exit of the escape passage 310.

[0037] Specifically, the escape zone 240 is located in the middle area of ​​the equipment floor 200, and multiple ventilation zones 230 are located on both sides of the escape zone 240. The escape ladder 241 is fixed at one end of the equipment floor 200 in the negative direction of the X-axis and extends upward to the exit of the escape passage 310.

[0038] In this way, by independently separating the escape area 240 within the equipment layer 200, the space of the escape area 240 is avoided from being occupied by other areas within the equipment layer 200, so as to prevent the escape route from being blocked. Furthermore, an escape ladder 241 is installed in the independently separated escape area 240, which extends from the escape area 240 to the exit of the escape passage 310, ensuring the safety and smoothness of accident escape, while also taking into account the daily inspection of the equipment room and improving the utilization rate of the passage.

[0039] Optionally, combined Figure 2 As shown, the multiple functional areas 210 include an escape area 240, in which an escape ladder 241 is provided, extending from the escape area 240 to the exit of the escape passage 310.

[0040] Specifically, the power distribution area 250 is separately enclosed by a fire-resistant partition wall 120, and a fire door 121 is installed on the fire-resistant partition wall 120. Within the power distribution area 250, power distribution cabinets (power distribution equipment) that are scattered in various compartments or power distribution rooms located outside the underground pipe gallery can be centrally installed within the power distribution area 250 to form a unified power distribution hub.

[0041] In this way, by setting up an independent power distribution area 250 within the equipment layer 200 and installing power distribution cabinets within the power distribution area 250, the power distribution equipment that was originally scattered in various compartments or located outside the pipe rack can be centrally arranged in the power distribution area of ​​the equipment layer, forming a unified and centralized power distribution hub. This avoids problems such as lengthy cable laying and low efficiency of cross-compartment operation and maintenance of power equipment caused by the dispersion of power distribution equipment, and improves the operation and maintenance response speed and boundary.

[0042] Optionally, combined Figure 2 As shown, the multiple functional areas 210 also include a power distribution area 250, in which power distribution cabinets are installed.

[0043] Specifically, the exhaust fan assembly primarily serves a ventilation function to ensure airflow within the power distribution area 250. Thus, by connecting the power distribution area 250 to the adjacent exhaust area 230 via the exhaust fan assembly, airflow within the power distribution area 250 can be achieved, ensuring the dryness of the internal space and consequently guaranteeing the reliability of the power distribution area 250 in operation.

[0044] Optionally, combined Figure 3 and Figure 7 As shown, an escape hydraulic manhole cover 311 is installed at the exit of the escape passage 310.

[0045] Specifically, the escape hydraulic manhole cover 311 has two states: open and closed. During routine inspections or firefighting, the escape hydraulic manhole cover 311 can be opened for convenient use. When closed, the escape hydraulic manhole cover 311 can cover the escape passage 310, preventing people or debris from accidentally falling in. Thus, by installing the escape hydraulic manhole cover 311 at the exit of the escape passage 310, the escape hydraulic manhole cover 311 can ensure both its function in routine inspections and firefighting, and also guarantee the safety of the escape passage 310.

[0046] Optionally, combined Figures 3 to 7 As shown, the air outlet of the ground layer 300 is equipped with horizontal rainproof ventilation louvers 320.

[0047] Specifically, the horizontal rainproof ventilation louver 320 can be installed at the air outlet of the ground layer 300 by existing means such as bolts or brackets. The horizontal rainproof ventilation louver 320 can cover the air outlet of the ground layer 300, ensuring air flow at the air outlet of the ground layer 300 while preventing people or debris from falling into the air outlet of the ground layer 300.

[0048] Thus, the air outlet of the ground layer 300 is equipped with horizontal rainproof ventilation louvers 320, which can play a safety protection role to prevent people or debris from falling into the air outlet of the ground layer 300.

[0049] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
