Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage engineering, in particular to a road surface rainwater outlet arrangement system. Background Art

[0002] In my country's urbanization construction, except for important trunk roads, the red line width of municipal roads is generally small, and municipal pipelines are not only of various types, but also of large number. Therefore, when arranging municipal pipelines in the cross section of the road, due to the limited space of sidewalks and green belts, it is inevitable to arrange some municipal pipelines under the motor vehicle lanes. According to relevant domestic specifications, drainage pipes with larger diameters are generally arranged along the center line of the road, so in most cases, municipal drainage pipes are usually set under the motor vehicle lanes of the road.

[0003] A large number of municipal pipelines and their inspection wells are located under motor vehicle lanes, which inevitably leads to some engineering problems. Due to the different structural forms of the inspection wells and roads, the road surface around the inspection well covers is unevenly stressed, and the road surface and roadbed are prone to disease and damage, which causes the inspection well covers to sink, break or make abnormal noises. Defects in inspection well covers not only greatly affect driving comfort and safety, but also affect the service life and appearance of the road.

[0004] In recent years, citizens have paid more and more attention to the problem of road inspection wells, so construction units have begun to propose the requirement of removing manhole covers from municipal motor vehicle lanes. However, due to the limitations of underground space conditions, it is unrealistic to completely avoid setting up drainage pipes under motor vehicle lanes. Therefore, a large number of scholars are studying how to design a new type of manhole cover to further improve the manhole cover's functions in anti-settling, anti-noise, and anti-damage. However, few people think about how to reduce the number of inspection wells from the root and reduce the problem of inspection well covers. When designing road rainwater pipes in China, in order to meet the discharge needs of road rainwater, the number of rainwater inspection wells is generally determined by the number of rainwater outlets. The result is that the layout spacing of the inspection wells is much larger than the specification requirements, resulting in too many road inspection wells. Therefore, how to optimize the layout and drainage method of road rainwater outlets, thereby improving the condition of rainwater pipe inspection wells and reducing the number of motor vehicle lane inspection wells, is urgent. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, a road surface rainwater outlet layout system is provided to increase the layout spacing of inspection wells, reduce the number of inspection wells, and reduce the road pavement disease problems caused by inspection well covers on municipal road motor vehicle lanes.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] The road surface rainwater inlet arrangement system includes a roadway, a rainwater inlet, a rainwater main pipe, a rainwater inspection well and a connecting large pipe; the rainwater main pipe is composed of several sections, and two adjacent rainwater main pipes are connected through a rainwater inspection well; multiple rainwater inlets are connected to the rainwater inspection well through a connecting large pipe;

[0008] It also includes a connecting piece and a connecting small tube; a through hole is provided on the rainwater main pipe between the rainwater inspection wells, the connecting piece is installed on the through hole, one end of the connecting small tube is connected to the rainwater outlet, and the other end of the connecting small tube is connected to the rainwater main pipe through the connecting piece.

[0009] According to the above technical solution, the connecting piece includes a circular tubular structure with a socket inside, the outer diameter of the circular tubular structure matches the size of the through hole, and one end of the connecting tube is fixedly inserted into the socket; a limit block is provided on the outer wall surface of the circular tubular structure.

[0010] According to the above technical solution, a socket is provided on the top of the circular tubular structure.

[0011] According to the above technical solution, the limiting block adopts a circular ring sheet structure, and the circular ring sheet structure is fixed on the outer wall of the circular tubular structure.

[0012] According to the above technical solution, the through hole is arranged vertically on the rainwater main pipe; the connecting small pipe adopts a bending structure, including an inclined section, a bending section and a vertical section, and the vertical section is inserted into the socket of the circular tubular structure.

[0013] According to the above technical solution, the slope of the pipeline connecting the large pipe is ≥1%, and the slope of the pipeline connecting the small pipe is ≥5%.

[0014] According to the above technical solution, the small pipes are connected by pipes with a diameter of 150 to 250 mm, and the large pipes are connected by pipes with a diameter of 300 to 400 mm.

[0015] According to the above technical solution, the rainwater inlets located on both sides of the rainwater inspection well are on the same vertical plane as the rainwater inspection well, and the rainwater inlets between two adjacent rainwater inspection wells are arranged in a staggered manner.

[0016] The utility model has the following beneficial effects:

[0017] Through holes and connectors are provided on the rainwater main pipe between the rainwater inspection wells, and the rainwater inlet and the rainwater main pipe are connected by means of the connector and the rainwater small pipe. Compared with the prior art, in which the rainwater inlet is connected to the rainwater main pipe through the rainwater inspection well, a form of directly connecting the rainwater inlet and the rainwater main pipe through the connector and the connecting small pipe is added.

[0018] In the design specifications, the maximum spacing of rainwater inspection wells is greater than the maximum spacing of rainwater outlets. In the prior art, since the rainwater outlets are connected to the rainwater main pipe only through the rainwater inspection wells, the spacing of the rainwater inspection wells must be adapted to the spacing of the rainwater outlets. In this solution, since the rainwater outlets and the rainwater main pipe can be connected not only by connecting the large pipe and the rainwater inspection well, but also by connecting the small pipe and the connector, the arrangement spacing of the rainwater inspection wells does not need to be adapted to the spacing of the rainwater outlets; on the same length of the roadway, the number of rainwater inspection wells is significantly reduced in the prior art, which greatly reduces the occurrence of road pavement diseases and improves driving comfort and safety.

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 1 to Figure 4 As shown, the road surface rainwater outlet arrangement system provided by the utility model.

[0026] Example 1

[0027] It includes a carriageway 1, a rainwater inlet 2, a rainwater main pipe 3, a rainwater inspection well 4 and a connecting large pipe 5; the rainwater main pipe is composed of several sections, and two adjacent rainwater main pipes are connected through the rainwater inspection well; multiple rainwater inlets are connected to the rainwater inspection well through the connecting large pipe.

[0028] It also includes a connector 6 and a small connecting tube 7; a through hole is provided on the rainwater main pipe between the rainwater inspection wells, the connector is installed on the through hole, one end of the small connecting tube is connected to the rainwater outlet, and the other end of the small connecting tube is connected to the rainwater main pipe through the connector.

[0029] In this embodiment, through holes and connectors are provided on the rainwater main pipe between the rainwater inspection wells, and the rainwater outlet and the rainwater main pipe are connected by means of the connector and the rainwater small tube; compared with the prior art, in which the rainwater outlet is connected to the rainwater main pipe through the rainwater inspection well, a form of directly connecting the rainwater outlet and the rainwater main pipe through the connector and the connecting small tube is added.

[0030] In the design specifications, the maximum spacing of rainwater inspection wells is greater than the maximum spacing of rainwater outlets. In the prior art, since the rainwater outlets are connected to the rainwater main pipe only through the rainwater inspection wells, the spacing of the rainwater inspection wells must be adapted to the spacing of the rainwater outlets. In this solution, since the rainwater outlets and the rainwater main pipe can be connected not only by connecting the large pipe and the rainwater inspection well, but also by connecting the small pipe and the connector, the arrangement spacing of the rainwater inspection wells does not need to be adapted to the spacing of the rainwater outlets; on the same length of the roadway, the number of rainwater inspection wells is significantly reduced in the prior art, which greatly reduces the occurrence of road pavement diseases and improves driving comfort and safety.

[0031] In Example 1, the connector includes a circular tubular structure 6-1 with a socket inside, the outer diameter of the circular tubular structure matches the size of the through hole, one end of the connecting tube is fixedly inserted into the socket; a stopper 6-2 is provided on the outer wall of the circular tubular structure. In this embodiment, the circular tubular structure is placed in the through hole of the rainwater main pipe, and the stopper is used to prevent the circular tubular structure from sliding into the rainwater main pipe; after the connecting tube is inserted into the socket of the circular tubular structure, the connection between the connecting tube and the rainwater main pipe is achieved.

[0032] Example 2

[0033] The structure and principle of Example 2 are similar to those of Example 1, except that a socket 6-3 is provided on the top of the circular tubular structure to facilitate the insertion of the connecting small tube into the circular tubular structure.

[0034] Preferably, the limiting block adopts a circular ring sheet structure, and the circular ring sheet structure is fixed on the outer wall of the circular tubular structure.

[0035] Example 3

[0036] The structure and principle of embodiment 3 are similar to those of embodiment 1 or 2, except that: the through hole is arranged vertically on the rainwater main pipe; the connecting pipe adopts a bending structure, including an inclined section 7-1, a bending section 7-2 and a vertical section 7-3, and the vertical section is inserted into the socket of the circular tubular structure. The connecting pipe relies on its own gravity and the friction between the inside of the socket of the circular tubular structure to achieve connection with the connecting piece. Due to the vertical arrangement of the through hole, the connecting piece is also fixed on the rainwater main pipe by its own gravity.

[0037] In Examples 1-3, the slope of the pipeline connecting the large pipe is ≥1%, and the slope of the pipeline connecting the small pipe is ≥5%.

[0038] Preferably, the small connecting pipe is a pipe with a diameter of 150-250 mm, and the large connecting pipe is a pipe with a diameter of 300-400 mm. The large connecting pipe and the small connecting pipe may also be pipes of other diameters. The small connecting pipe is a plastic pipe with a diameter of 200 mm, and the large connecting pipe is a reinforced concrete pipe with a diameter of 300 mm.

[0039] In Examples 1-3, preferably, the rainwater inlets located on both sides of the rainwater inspection well are on the same vertical plane as the rainwater inspection well, and the rainwater inlets between two adjacent rainwater inspection wells are arranged in a staggered manner.

[0040] The working principle of this utility model:

[0041] The system is designed based on the situation that there are sidewalks (with tree pits) on both sides of the municipal road for motor vehicles. The road red line width is 20m, the sidewalk is 3m, the motor vehicle lane is 14m wide, the diameter of the rainwater main is d800, and the rainwater inlet uses a single-grate side ditch type rainwater inlet.

[0042] like Figures 1 to 4 As shown, in the utility model, a rainwater inlet-inspection well system is formed by a rainwater inlet, a large connecting pipe and a rainwater inspection well, so that the rainwater inlet is connected to the rainwater main pipe; a rainwater inlet-pipeline system is formed by a rainwater inlet, a small connecting pipe and a connector, so that the rainwater inlets are connected to the rainwater main pipe. The connector includes a socket, a spigot and a limit block. The socket and the spigot of the connector can stably connect the small connecting pipe and the rainwater main pipe together, ensuring that the rainwater collected by the rainwater inlet can be directly discharged into the rainwater main pipe. Among them, the limit block has the function of preventing the connector from moving and sliding.

[0043] like Figure 1 As shown, the spacing between rainwater inspection wells is set to 100m, and the rainwater inlets are arranged on the side of the motor vehicle lane with a spacing of 50m. After the rainwater inlets collect rainwater from the road surface, they enter two systems respectively and are finally discharged into the rainwater main.

[0044] like Figure 2 As shown, the rainwater on the road surface is collected by the rainwater outlet and directly discharged into the rainwater main pipe through the connecting small pipe. The connecting small pipe and the rainwater main pipe are no longer connected by setting up an inspection well. Among them, the connecting small pipe adopts a d200 plastic pipe, and the pipe slope is ≥5%.

[0045] like Figure 3 As shown, the rainwater on the road surface is collected by the rainwater inlet and then discharged into the rainwater inspection well through the large pipe, and finally enters the rainwater main pipe. The rainwater inspection well plays the role of inspecting and maintaining the pipeline system. Among them, the large pipe is connected with a reinforced concrete pipe of d300, and the slope of the pipe is ≥1%.

[0046] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of patent application of the present invention still fall within the protection scope of the present invention.
