[0061] A multifunctional integrated node for intersections, lifting openings and ventilation openings of an underground comprehensive pipe gallery adopts a layered caisson structure with high space utilization, reasonably coordinates the functional requirements of each comprehensive pipe gallery, and combines the functions of intersections, ventilation openings and lifting openings.

[0062] See also Figures 1 to 7 The underground integrated pipe gallery node includes a caisson 1, and the caisson 1 preferably adopts a rectangular caisson, and a circular caisson may be considered when conditions are limited.

[0063] The caisson 1 is provided with an upper pipe gallery layer, a middle equipment layer and a lower pipe gallery layer, and the upper pipe gallery layer, the middle equipment layer and the lower pipe gallery layer are separated by a top plate 2, an upper floor slab 3, a middle floor slab 4 and a bottom plate 5 which are arranged in sequence from bottom to top.

[0067] Considering the intersection, vents and hoisting functions of the local underground integrated pipe gallery node, the upper floor 3 is provided with an upper ventilation hole and partition wall 301, an upper pipeline intersection hole 302, an upper hoisting hole reserved hole 303, and an upper manhole reserved hole 304. For multi-cabin underground integrated pipe gallery nodes, the first compartment A, the second compartment B, and the third compartment C are all required to be provided with an upper pipeline intersection hole 302 and an upper manhole reserved hole 304. Considering the long distance between the top pipes of the lower pipe gallery and the requirements for the setting of vents, the function of the vents of the upper pipe gallery layer here is to ventilate the lower pipe gallery layer, and a partition wall should be used to separate the upper ventilation holes into independent ventilation shafts. According to the height of the upper pipe gallery layer, a straight ladder is used for the upper stairs.

[0068] In order to realize the normal function of the upper pipeline, the upper pipeline needs to be reasonably designed in combination with its maximum turning radius, the space in the well, the ventilation duct extending from the middle equipment layer, and the intersection of the upper pipeline and the lower pipeline. For the specific direction of the upper pipeline, please refer to Figure 8 .

[0069] The middle equipment layer is a key connection and conversion layer connecting the upper pipe gallery layer and the lower pipe gallery layer, and has four main functions: first, to realize the cross connection of the upper pipeline and the lower pipeline, that is, the intersection function; second, to realize the ventilation function of the lower pipe gallery layer, that is, the vent function; third, to isolate the upper pipe gallery layer and the lower pipe gallery layer into two independent fire partitions; fourth, to realize the safe traffic of the vertical space in the caisson 1, while taking into account the functions such as the lifting of equipment inside the pipe gallery. The middle equipment layer generally needs to reserve ventilation ducts, ventilation equipment, power distribution rooms, stairs, pipeline crossing spaces, etc. To realize the above functions in a limited space, it is necessary to combine the professional needs of power distribution, HVAC, structure, and overall, and make reasonable arrangements.

[0070] See also Figure 1 , Figure 2 and Figure 5The middle equipment layer includes the first ventilation room D, the second ventilation room E, the first power distribution room F, the second power distribution room G, the first auxiliary room H, the second auxiliary room I, the traffic area J, ventilation equipment, ventilation ducts, power distribution equipment, middle fireproof partition wall 6, middle fireproof door 7, and middle stairs; the first ventilation room D, the second ventilation room E, the first power distribution room F, the second power distribution room G, the first auxiliary room H, and the second auxiliary room I are separated by setting multiple middle walls, and the traffic area J is set in the middle and connected to the cabin of the middle equipment layer by setting a middle fireproof partition wall 6, a middle fire door 7 is arranged on the middle wall and the middle fire partition wall 6, ventilation equipment and ventilation ducts are arranged in the first ventilation room D and the second ventilation room E, power distribution equipment is arranged in the first distribution room F, the second distribution room G, the first auxiliary room H and the second auxiliary room I, the power distribution equipment in the first distribution room F and the second distribution room G meets the use of the ventilation equipment in the first ventilation room D and the second ventilation room E, and the power distribution equipment in the first auxiliary room H and the second auxiliary room I meets the auxiliary power distribution function requirements of the upper pipe gallery layer and the lower pipe gallery layer.

[0071] Since there are often high-risk pipelines such as gas and cables inside the underground integrated pipe gallery, for the multi-cabin underground integrated pipe gallery nodes, the ventilation ducts of the cabins used for gas pipeline inlet and outlet lines need to be separated from the ventilation ducts of other cabins. In addition to considering independent internal transportation methods and escape routes, each cabin should also consider the functional requirements of intersections, pipeline intersection layout and reserved openings, etc. The equipment functional area should be considered to be separated from the horizontal and vertical transportation areas J of personnel when conditions permit. Therefore, considering the key role of the middle-level equipment layer, the middle-level floor 4 is provided with a middle-level ventilation equipment opening 401, a middle-level pipeline intersection opening 402, and a middle-level staircase reserved opening 403. Each opening needs to be multiplied according to the number of cabins in the middle-level equipment layer. The middle-level staircase reserved opening 403 is also provided with a fireproof roller shutter. According to the height of the middle-level equipment layer, the middle-level staircase adopts an inclined steel ladder.

[0072] See also Figure 1 , Figure 2 and Figure 6The lower pipe gallery layer includes a fourth cabin K, a fifth cabin L, a sixth cabin M, a lower pipeline inlet, a lower pipeline outlet, a lower fireproof partition wall 8, a lower fireproof door 9, and a lower staircase 10; the lower pipe gallery layer adopts a three-cabin separation design, the fourth cabin K, the fifth cabin L, and the sixth cabin M are separated by two lower walls arranged along the Y direction, the fourth cabin K, the fifth cabin L, and the sixth cabin M are respectively provided with a lower pipeline inlet and a lower pipeline outlet on the well walls on both sides of the X direction, the fourth cabin K, the fifth cabin L, and the sixth cabin M are provided with a lower fireproof partition wall 8 and a lower staircase 10, the lower fireproof partition wall 8 divides the cabin of the lower pipe gallery layer into two parts in the X direction, so that two independent fire partitions are formed in the cabin of each lower pipe gallery layer, and a lower fireproof door 9 is arranged on the lower fireproof partition wall 8.

[0073] The Y-direction sides of the lower pipe gallery layer are connected to the X-direction pipeline system. The lower pipeline inlet on one side of the lower pipe gallery layer Y is connected to the caisson 1 by a jacking pipe method and then crosses the obstacle to be connected to a caisson. The lower pipeline outlet on the other side of the lower pipe gallery layer Y is connected to the caisson 1 by a grooving method or a jacking pipe method, and is connected to the pipe gallery of the X-direction pipeline system or another caisson, so that the lower pipe gallery layer and the X-direction pipeline system form a continuous pipe gallery pipeline system.

[0074] The lower pipeline inlet and the lower pipeline outlet can form a certain reasonable height difference to meet the lower pipeline inlet and outlet, or there can be no height difference, so that the lower pipeline can enter and exit smoothly. In addition to realizing the vertical traffic of the lower pipeline corridor, the lower staircase 10 also needs to consider the position of the lower pipeline inlet and the lower pipeline outlet, so the lower staircase 10 uses concrete stairs, staircase platforms, and inclined steel stairs. For the specific direction of the lower pipeline, please refer to Figure 8 .

[0075] See also Figure 7 The bottom plate 5 is provided with a reserved hole 501 for a water collection hole.

[0076] In actual implementation, the plane size of the caisson of the local underground integrated pipe gallery node should be large enough to meet the normal functional requirements of intersections, ventilation openings and lifting openings, but at the same time, the structural size should be reduced as much as possible to improve economic benefits. The upper pipe gallery layer is shallowly buried, and is connected to the pipe gallery of the pipeline system by excavation construction such as slope reduction or foundation pit enclosure. The middle equipment layer is exposed to the ground through ventilation ducts to form a ventilation pavilion. The lower pipe gallery layer is buried deeper and is connected to other caissons by a top pipe structure.

[0077] In addition, the caisson 1 of the local underground comprehensive pipeline corridor node can also be replaced by a foundation pit retaining structure, and the design and construction can be directly carried out using the foundation pit retaining structure as a carrier.

[0078] It should be noted that the fully described invention may also have a variety of variations and modifications, and is not limited to the specific embodiments described above. The above embodiments are merely illustrative of the invention, not limiting thereof. In short, the scope of protection of the invention should include those variations or substitutions and modifications that are obvious to a person of ordinary skill in the art.
