Abstract
Description
Technical Field
[0001] The utility model belongs to the field of comprehensive pipe gallery engineering, and specifically relates to a side-opening node structure for reducing the buried depth of the comprehensive pipe gallery. Background Art
[0002] The utility corridor is used to accommodate structures and ancillary facilities of two or more types of urban engineering pipelines, and is usually set up under urban roads. In order to meet the needs of personnel entry and exit, daily inspection, maintenance, emergency rescue, etc., the utility corridor should be equipped with personnel entrances and exits, escape holes, hoisting holes, and ventilation holes. There should be no less than two escape holes and ventilation holes in one fire zone (200 meters), and the distance between two hoisting holes should not be greater than 400 meters.
[0003] When the municipal road is close to the buildings on both sides (within 5.0 meters), and the construction excavation conditions are limited, if the conventional practice is followed to set the pipeline corridor node on the top plate of the pipeline corridor and extend it to both sides to the edge line of the motor vehicle lane, the excavation depth of the foundation pit will be increased, the project investment will be increased, and there will be certain safety hazards in the construction. In order to avoid the above problems, the utility model proposes a side-opening node structure for the comprehensive pipeline corridor to reduce the buried depth of the comprehensive pipeline corridor. Utility Model Content
[0004] The utility model aims to provide a side-opening node structure for reducing the buried depth of a comprehensive pipe gallery, so as to solve the problem that the conventional node setting method has construction safety hazards when the municipal road is close to the buildings on both sides.
[0005] The technical solution of the utility model is: a side-opening node structure for reducing the buried depth of an integrated pipe gallery, an access passage, an escape passage and two air ducts are arranged on the sides of the connection between two fire partitions, the access passage and the escape passage are respectively connected to the cabins of the integrated pipe gallery, the two air ducts are respectively connected to the two cabins, the access passage connects the personnel entrance and exit, a manhole is arranged at the top of the escape passage, a first ladder is arranged below the manhole, and a vent is arranged at the top of the air duct.
[0006] As a further improvement of the utility model, two air ducts are located between the entrance and exit passage and the escape passage.
[0007] As a further improvement of the utility model, a hoisting passage is provided in communication with the side of the cabin, a hoisting opening is provided at the top of the hoisting passage, and a second ladder is provided below the hoisting opening.
[0008] The beneficial effects of the utility model are as follows: the utility model sets each node channel on the side of the integrated pipe gallery instead of setting it on the top in the conventional method, which can reduce the buried depth of the pipe gallery body, reduce the excavation depth of the foundation pit, save engineering investment, and reduce construction safety hazards. The utility model has a simple structure, is easy to implement, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The utility model is described in detail below in conjunction with the accompanying drawings.
[0017] like Figure 1-6 As shown, a side-opening node structure for reducing the buried depth of an integrated pipe gallery is provided with an access passage 2, an escape passage 3 and two air ducts 4 at the side of the connection between two fire partitions. The access passage 2 and the escape passage 3 are respectively connected to the cabin 1 of the integrated pipe gallery, and the two air ducts 4 are respectively connected to the two cabins 1. A retaining wall 9 is provided between the air duct 4 and the cabin 1, and a fan 10 is provided on the retaining wall 9; the access passage 2 is connected to the personnel entrance 5 located on the ground through stairs, a manhole 6 is provided at the top of the escape passage 3, a first ladder 8 is provided below the manhole 6, and a ventilator 7 is provided at the top of the duct 4. The manhole 6 and the ventilator 7 are located above the ground.
[0018] The two air ducts 4 are located between the entrance and exit passage 2 and the escape passage 3, so that the pipe gallery nodes are unified in one place and the excavation area is reduced.
[0019] A hoisting passage 11 is provided in communication with the side of the cabin 1 . A hoisting opening 12 is provided at the top of the hoisting passage 11 . The hoisting opening 12 is located above the ground. A second ladder 13 is provided below the hoisting opening 12 .
[0020] The personnel entrance and exit 5 , the manhole 6 , the ventilation opening 7 and the lifting opening 12 are all located outside the edge line 14 of the motor vehicle lane.
[0021] The elevations of the access passage 2, escape passage 3, air duct 4, and hoisting passage 11 are higher than the integrated pipe gallery. Stairs are set at the junction of the access passage 2, escape passage 3, hoisting passage 11 and cabin 1 to prevent people from slipping when passing through and ensure safety.
[0022] The utility model is applicable to single-cabin and double-cabin integrated pipe corridors. The single-cabin integrated pipe corridor only needs to be provided with the node structure of the utility model on one side of the integrated pipe corridor, while the double-cabin integrated pipe corridor needs to be provided on both sides of the integrated pipe corridor, that is, the node structure of the utility model is provided on the cabins 1 on both sides, such as Figure 1 Each cabin 1 is provided with an air duct 4 at both ends, and each cabin 1 is provided with an entrance and exit passage 2 and an escape passage 3 at both ends.
[0023] When the municipal road is close to the buildings on both sides (within 5.0 meters) and the construction excavation conditions are limited, the node structure of the utility model is used to set nodes on the side of the comprehensive pipeline corridor, thereby reducing the buried depth of the comprehensive pipeline corridor, reducing the excavation depth of the foundation pit, saving project investment, and reducing construction safety hazards.
[0024] When various pipelines in the cabin 1 pass through various channels (entry and exit channel 2, escape channel 3, air duct 4, lifting channel 11), it is possible to consider setting the pipelines close to the channel side on the top plate of the cabin 1.
