TECHNICAL FIELD

[0001] The present application relates to the technical field of comprehensive pipe gallery, in particular to an active drainage type combined pipe gallery. BACKGROUND

[0002] The urban comprehensive pipe gallery is also called common trench, which is a public tunnel for laying power, communication, broadcast television, water supply, drainage, heat, gas and other municipal pipelines underground in the city. It is a modern, scientific and intensive urban infrastructure. The construction of urban underground comprehensive pipe gallery solves the problems of repeated excavation of pavement, dense overhead line network and frequent pipeline accidents.

In recent years, it is a new trend to develop pipe gallery construction in the process of urban renewal (overhead lines into the ground, rainwater and sewage diversion reconstruction, etc.).

[0005] At present, for the areas where urban renewal projects need to be carried out, there are objective problems such as dense buildings, old roads, narrow and dense roads, various cables and pipelines, etc. The trunk type pipe gallery and branch type pipe gallery which need to be set up in multiple warehouses are often difficult to build, and it is urgent to develop functionally integrated small combined pipe gallery.

[0006] In addition, for some old urban areas, ancient towns and other areas, there are often problems such as imperfect drainage system, dense overhead lines, cable flying lines, etc., which are prone to cause waterlogging or fire safety hazards; and the existing pipe gallery internal drainage mainly adopts the method of collecting water in the pit and pumping it out, which is difficult to operate and manage.

Detailed Implementation

[0025] The following will further explain the concept, specific structure, and technical effects of the present invention in conjunction with the accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention.

[0026] Example:

[0027] like Figs. 1-2 As shown, the active drainage type combined pipe gallery consists of three compartments arranged in sequence: water supply compartment 1, cable compartment 2 and drainage compartment 3. Waterproof cover plates 4 are installed on the top of water supply compartment 1 and cable compartment 2 respectively, and water permeable cover plates 5 are installed on the top of drainage compartment 3. Water supply pipes 6 are installed inside water supply compartment 1.

[0028] The upper part of the inner wall of the drainage chamber 3 is supported by several pipe supports 8, and the pipe supports 8 are arranged along the length of the sewage pipe 7. The bottom of the drainage chamber 3 is provided with a rainwater channel 11. The inner wall of the drainage chamber 3 is also provided with a liquid level sensor 9, which is electrically connected to the ground control cabinet 10.

[0029] The inner side wall of the cable bin 2 is layered with cable supports 13 for laying functional cables 12, and the inner bottom of the cable bin 2 is provided with a water collecting groove 14 near one side of the drainage bin 3, and the bottom of the water collecting groove 14 is connected to the rainwater channel 11 through a pre-buried drainage pipe 15 to drain the rainwater collected in the cable bin 2 into the rainwater channel 11.

[0030] The drainage pipe 15 is provided with an intelligent drainage valve 16 at one end near the drainage bin 3, and the intelligent drainage valve 16 is electrically connected with the ground control cabinet 10, so that when the water level in the rainwater channel 11 is lower than that in the cable bin 2, the intelligent drainage valve 16 can be automatically opened for drainage through the water head difference; when the water level in the rainwater channel 11 is higher than that in the cable bin 2, the pressure can drive the intelligent drainage valve 16 to be automatically closed to prevent rainwater from flowing back into the cable bin 2.

[0031] In some embodiments, when the water level in the rainwater channel 11 is higher than that in the cable bin 2, the intelligent drainage valve 16 can also be automatically closed by remote control of the control cabinet to prevent rainwater from flowing back into the cable bin.

[0032] The main innovation of the present application is that it is suitable for construction in limited space, dense overhead line in old urban areas and ancient towns, and the combined pipe gallery structure design of active drainage effectively solves the problems of limited space pipe gallery construction and internal drainage of the pipe gallery.

[0033] More specifically, the drainage bin 3 is arranged near the municipal road, the water supply bin 1 is arranged near the residents on both sides, and the entire pipe gallery is preferably arranged under the sidewalk, and can also be arranged in non-motor vehicle lane, motor vehicle lane, etc.

[0034] In order to ensure that the hydraulic slope of the sewage pipe meets the design requirements, and at the same time meet the needs of standardized construction of the gallery, an adjustable pipe bracket 17 is arranged between the pipe support 8 and the sewage pipe 7, the adjustable pipe bracket 17 and the pipe support 8 are fixed by adjusting bolts 18, and the height of the adjustable pipe bracket 17 can be adjusted to a proper position according to the slope requirement of the sewage pipe 7 (avoiding the need to set each pipe support 8 at different heights according to the slope, reducing the difficulty of prefabrication or on-site pouring, and effectively responding to the change of actual site slope).

[0035] The cable cabin 2 is used for orderly arranging the communication, power and other related function cables 12, the cables are installed along the side wall through the insulated metal cable support 13, and are arranged in layers according to different types of the function cables 12, and the layer height should meet the arrangement spacing requirement of the function cables 12. In order to ensure that the function cables are not affected by rainwater and the like, the water collecting tank 14 is arranged at the bottom of the cable cabin 2 close to the side of the drainage cabin, and the bottom of the water collecting tank 14 guides and drains the rainwater collected in the cable cabin 2 into the rainwater channel 11 through the pre-buried drainage pipe 15. The end of the drainage pipe 15 is installed close to the inner side wall of the drainage cabin 3, and a one-way opening micro intelligent drainage valve 16 that can be opened to the drainage cabin 3 is arranged. The intelligent drainage valve 16 is connected with the ground control cabinet 10. The driving mode of the intelligent drainage valve 16 is electric and pressure driven. In general, when the water level in the rainwater channel 11 is lower than the water level in the cable cabin 2, the intelligent drainage valve 16 is automatically opened for drainage through the water head difference. When the water level in the rainwater channel 11 is higher than the water level in the cable cabin 2, the pressure automatically closes the intelligent drainage valve 16, so as to prevent rainwater from flowing back into the cable cabin 2. The micro intelligent drainage valve 16 can also be automatically controlled remotely. When it is monitored that the water level is higher than the warning water level, the drainage valve can be remotely controlled to be closed, so as to prevent rainwater from flowing back.

[0036] Since the pipe diameter of the water supply pipe in the old city area, ancient town and the like is usually small, the water supply cabin 1 adopts a small section size, and the side wall of the water supply cabin 1 close to the side of the resident user is provided with a branch pipe connection inlet 19 at a certain distance, so as to facilitate the later household connection installation.

[0037] In some embodiments, in order to prevent water from seeping in, a sealing waterproof structure 20 is arranged at the connection between the waterproof cover plate 4 and the pipe gallery, the sealing waterproof structure 20 is specifically that the waterproof cover plate 4 and the water permeable cover plate 5 are both designed in a bayonet structure, and an expansion waterstop tape is arranged on the bayonet.

[0038] In other embodiments, the top of the water collecting tank 14 is provided with a grille 21 for removing a small amount of garbage in the rainwater.

[0039] In summary, the present application has the following advantages:

[0040] 1. In many old city areas and ancient towns, the underlying surface has poor permeability, a large runoff coefficient and low terrain, and urban waterlogging is prone to occur in heavy rain, so the rainwater pipe laying requirement is high, and the rainwater channel 11 design can effectively improve the rainwater flow capacity and avoid waterlogging.

[0041] 2. In old city areas and ancient towns, there are complex cables and wires, serious roof fly lines and the like, and through the combined pipe gallery construction, the disordered power and telecommunications fly lines are collected into the pipe gallery, which can effectively reduce the fire safety risk and is beneficial to the later maintenance.

[0042] 3. The water collection tank 14 and drainage pipe 15 can ensure that even if rainwater enters the cable compartment 2, it can be drained in time, which can protect the functional cable 12 and make up for the difficulty of drainage in traditional cable-type pipe corridors, which has an adverse effect on the cable life.

[0043] 4. The intelligent drain valve 16 can ensure that when the water level in the rainwater channel 11 is too high, rainwater will not flow back into the cable compartment 2 through the drain pipe 15, thus ensuring the safety of the cable compartment 2 under high rainwater flow.

[0044] 5. The pipe support 8 is equipped with an adjustable pipe bracket 17, which can not only meet the slope requirements of the sewage pipe 7, but also avoid the need to set each pipe support 8 at different heights during prefabrication or on-site casting, reducing the difficulty of use. At the same time, it can also effectively cope with the needs of actual on-site slope changes. Only the pipe bracket 17 needs to be adjusted, without the need to reinstall the pipe support 8.

[0045] 6. The waterproof cover plate 4, the permeable cover plate 5, and the snap-fit ​​design are conducive to waterproofing of the cable compartment 2 and the water supply compartment 1, as well as water collection in the drainage compartment 3, and can play a sponge effect.

[0046] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
