Description

Technical Field

[0001] The present invention relates to the technical field of urban underground integrated pipe gallery engineering, and in particular to a gravity flow sewage pipe inlet gallery system under a flat slope road. Background Art

[0002] As a key carrier of urban pipelines, integrated pipe corridors reduce the need for direct burial of municipal pipelines, effectively addressing a range of issues, including repeated road excavation and the dense concentration of overhead pipelines. Currently, integrated pipe corridors primarily accommodate pipelines for water supply, electricity, communications, heating, and recycled water. However, integrating gravity-discharged sewage pipes into integrated pipe corridors has been a hot topic of discussion.

[0003] There are currently many problems with gravity flow sewage pipes entering the corridor: First, in cities with flat terrain and shallow road slopes, the entry of sewage pipes into the corridor will increase the depth of the integrated pipeline corridor and increase the cost of the integrated pipeline corridor; Secondly, the existing method uses reinforced concrete inspection wells in the corridor to connect the sewage branch pipes, and gate wells are set at a certain distance to cut off the sewage main pipe. The location of the inspection wells requires a larger corridor width, which increases the corridor space and cost. Finally, the sewage pipes contain a large amount of floating objects and sediment, and toxic and harmful gases such as hydrogen sulfide, methane, and carbon monoxide are produced in the anaerobic environment. After the sewage pipes enter the corridor, the distance between the inspection wells becomes larger and the operating space in the corridor is limited, which is not conducive to the dredging and ventilation of the sewage pipes in the corridor. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a gravity flow sewage pipe corridor system under a flat slope road, which can effectively solve the connection of sewage branch pipes and neighborhood branch pipes, ventilate and flush sewage pipes, and reduce the buried depth of sewage pipe corridors.

[0021] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0022] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0023] Reference Figures 1 to 7 A gravity flow sewage pipe inlet corridor system under a flat slope road includes: a corridor body 10. A sewage tank 20 is disposed within the corridor body 10. A sewage main pipe 30 is disposed in the sewage tank 20. The sewage main pipe 30 is arranged along the length of the sewage tank 20. A plurality of pipe support piers 31 are disposed below the sewage main pipe 30. The bottom surface of the sewage tank 20 is undulating. The sewage main pipe 30 rises and falls with the sewage tank 20. The pipe support piers 31 cooperate with the sewage tank 20 to achieve the wavy arrangement of the sewage main pipe 30. The corridor also includes a sewage connection well 40. The sewage connection well 40 is connected to the sewage main pipe 30 and is used to connect sewage branch pipes 41 at different buried depths. The corridor also includes a flushing system 50. The flushing system 50 is connected to the sewage connection well 40. The flushing system 50 is used to flush the pipes of the sewage connection well 40 and part of the sewage main pipe 30.

[0024] It can be understood that the wavy sewage tank 20 and sewage main pipe 30 greatly reduce the required burial depth of the sewage main pipe 30, reduce the cost of the integrated pipeline corridor, and at the same time realize the connection of the sewage branch pipe 41 through the sewage connection well 40, without the need for a larger pipeline corridor width, saving costs, and the sewage main pipe 30 is flushed in sections through the flushing system 50 to avoid accumulation of dirt in the pipeline.

[0025] It should be noted that in flat areas, the main body of the pipeline corridor is arranged in a wave shape in combination with the sewage inlet corridor, and the buried depth is reduced by 0.9 meters per kilometer (under normal slope conditions). By changing the height of the pipeline piers 31, the middle and lower space in the pipeline corridor main body 10 is fully utilized to meet the design slope of the sewage pipeline, thereby reducing the project cost.

[0026] Reference Figure 1 The sewage main 30 is provided with a plurality of top inspection wells 60. The top inspection wells 60 are spaced 60 to 70 meters apart. The top inspection wells 60 are used to connect the neighborhood branch pipes 61 located at the top of the pipe gallery.

[0027] Reference Figure 3 The extended manhole 60 includes a steel pipe adapter 62, a manhole body 63, a manhole cover 64, an inspection ladder 65, and a brick trough 66. The manhole body 63 is connected to the sewage main 30 via the steel pipe adapter 62. The manhole cover 64 is located at the top of the manhole body 63. The inspection ladder 65 is installed on the side wall of the manhole body 63. The brick trough 66 is located below the manhole body 63. The neighborhood branch pipe 61 is connected to the manhole body 63.

[0028] Reference Figure 1 and Figure 7 The sewage main pipes 30 of the two adjacent top inspection wells 60 are provided with an inspection port 70. The inspection port 70 includes an inspection tee 71 and an inspection blind plug 72.

[0029] Reference Figure 1 The sewage main 30 is equipped with a plurality of vent pipes 11, which are spaced 200 meters apart. The vent pipes 11 pass through the concrete piers 12 above the main pipe gallery 10 and extend upward. The ends of the vent pipes 11 are equipped with vent caps 13. The bottom of the vent caps 13 is greater than 0.6 meters from the ground.

[0030] Reference Figure 4 The sewage connection well 40 includes a connection well body 42, a sludge trough 43, a connection well cover 44, a connection well ladder 45, and a sewage connection pipe 46. A sewage branch pipe 41 is connected to the connection well body 42. The sludge trough 43 is located at the bottom of the connection well body 42. The connection well cover 44 is located at the top of the connection well body 42. The connection well ladder 45 is located on the side wall of the connection well body 42. The sewage connection pipe 46 connects the connection well body 42 to the sewage main line 30.

[0031] It should be noted that the sewage connection well 40 meets the connection requirements of sewage branch pipes 41 with different buried depths, and solves the connection problem of sewage branch pipes 41 on both sides; the sewage connection well 40 is provided with a sludge tank 43, which can effectively deposit some particulate pollutants and slow down the impact of pollutant accumulation on the sewage main pipe 30.

[0032] Reference Figure 4 The flushing system 50 includes a flushing well 51, a flushing water pipe 52, a flushing valve 53, and a flushing well cover 54. The sewage connection pipe 46 passes through the flushing well 51. The flushing water pipe 52 is disposed in the flushing well 51 and communicates with the sewage connection pipe 46. The flushing valve 53 is disposed on the sewage connection pipe 46. The flushing valve 53 prevents flushing water from entering the docking well 42.

[0033] It should be noted that the operating space within the main pipe corridor 10 is limited. By providing a flushing well 51, an inspection port 70, and a roof-mounted inspection well 60, both mechanical and routine manual dredging are provided. This system combines external flushing for dredging, supplemented by cleaning the inspection ports within the corridor. This system does not occupy internal corridor space and effectively prevents flushing water from overflowing. Each section can be independently flushed via gate valves, making maintenance of sewage pipes entering the corridor more convenient.

[0034] It should be noted that, in an embodiment of the present invention, a flushing system 50 is set at a certain distance. It is recommended to set up one set for each pipe corridor partition or determine the specific distance in combination with the service of the plot. When the flushing system 50 flushes, the upstream flushing well 51 closes the flushing valve 53 to prevent the flushing water from overflowing into the docking well body 42, and the downstream flushing well 51 opens the flushing valve 53 to flush the sludge in the sewage main 30 into the docking well body 42.

[0035] Reference Figure 6 , two sewage connection wells 40 form a group. The two sewage connection wells 40 are respectively arranged on both sides of the pipe gallery body 10, and the two sewage connection wells 40 are connected by a connecting channel 47. One of the two sewage connection wells 40 is connected to a sewage connection pipe 46.

[0036] It is worth noting that in some embodiments of the present invention, when sewage branch pipes 41 need to be connected on both sides of the tunnel main body 10, two sewage connection wells 40 are respectively arranged on both sides of the tunnel main body 10 and connected through a connecting channel 47. One of the sewage connection wells 40 is connected to the sewage main pipe 30 through a sewage connecting pipe 46.

[0037] Furthermore, in some embodiments of the present invention, the connecting channel 47 is inclined with a slope of 0.5%.

[0038] Reference Figure 5 , further comprising a plurality of sewage knife gate valves 32. The plurality of sewage knife gate valves 32 are arranged on the sewage main pipe 30. The sewage knife gate valves 32 are located downstream of the sewage connecting pipe 46.

[0039] It is worth noting that the sewage knife gate valve 32 is used to divide the sewage main pipe 30 to achieve segmented flushing.

[0040] It's worth noting that in this embodiment of the present invention, the sewage main 30 and various connecting pipes are made of ductile iron, while the roof inspection well 60, vent pipe 11, and flushing water pipe 52 utilize steel fittings. The corridor sewage pipe is constructed of ductile iron pipes and steel fittings, combining the durability and stability of ductile iron pipes with the ease of maintenance. Steel fittings offer fewer joints, better sealing, flexible fitting configuration, and ease of installation.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Of course, the present invention is not limited to the above-mentioned embodiments.
