Description

Technical Field

[0001] The utility model relates to the technical field of rain and sewage diversion, in particular to a roof rain and sewage diversion structure. Background Technique

[0002] At present, in the process of urban development, the construction of sewage treatment supporting pipelines has been comprehensively strengthened, and the interception and collection of sewage in urban villages, old urban areas and urban-rural fringe areas have been strengthened. The existing combined sewer systems should be accelerated to implement rain and sewage diversion transformation. For those that are difficult to transform, measures such as interception, storage and treatment should be taken. Except for arid areas, rain and sewage diversion is implemented in the construction of new urban areas, and in areas with conditions, the collection, treatment and resource utilization of initial rainwater are promoted.

[0003] In the process of implementing rain and sewage diversion transformation, the transformation of rain and sewage risers in medium and high-rise buildings has become a key and difficult point in the rain pollution prevention and control actions. At present, the conventional design methods include the method of newly building and transforming rain and sewage risers and the method of newly building building diverters. Among them, the method of newly building and transforming rain and sewage risers is generally only applicable to the external risers of low-rise buildings, and the feasibility of transforming high-rise and indoor risers is poor, and the construction cost and difficulty are very high; while for the method of newly building building diverters, continuous maintenance and management are required after completion, the operation of the equipment requires power support, and in essence, it is still a combined rain and sewage drainage method into the rainwater system during rainfall, and rain and sewage diversion cannot be completely achieved. When rain and sewage are discharged together into the sewage treatment system or into the river, it will cause an increase in the load of the pipe network or river pollution. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a roof rain and sewage diversion structure, which can solve the problem that when rain and sewage are discharged together into the municipal rainwater system or into the river, it will cause an increase in the load of the pipe network or river pollution.

[0005] For this reason, the utility model adopts the following technical solutions:

[0006] A roof rain and sewage diversion structure includes a plurality of risers for collecting domestic sewage, and also includes a plurality of circumferential drainage pipes arranged along the circumference of the roof. A water collection port for collecting rainwater is provided below each riser. The water collection port is adjacent to the parapet wall arranged along the circumference of the roof. A drainage pipe out of the wall is provided at the lower part of the parapet wall. One end of the drainage pipe out of the wall is communicated with the water collection port, and the other end of the drainage pipe out of the wall passes through the parapet wall and is communicated with the circumferential drainage pipe on one side below it. The lower part of the circumferential drainage pipe is connected with a plurality of drainage outflow structures through a plurality of diversion pipes.

[0007] On the basis of adopting the above technical solutions, the utility model can also adopt the following further technical solutions, or use a combination of these further technical solutions:

[0008] A connection bracket is fixed on the upper part of the parapet wall.

[0009] The lower end of the connecting bracket extends below the circumferential scattered drain pipes. The connecting bracket includes an inclined section provided at its lower part and extending downward and outward. The end of the inclined section extends below the circumferential scattered drain pipes. The end of the inclined section is provided with a horizontal section extending outward. The horizontal section is located below the circumferential scattered drain pipes for supporting the circumferential scattered drain pipes.

[0010] The connecting bracket includes a connecting main body part which is concave with an opening facing downward. The parapet wall is located within the opening of the connecting main body part. The connecting main body part and the parapet wall are fixedly connected by connecting bolts.

[0011] The side surface of the connecting main body part is in an H shape. The inclined section is located on the side of the connecting main body part facing the outer side of the roof. Each connecting main body part is connected with two such inclined sections.

[0012] The horizontal section is located between the circumferential scattered drain pipes and the scattered drain outflow structure, and the horizontal section does not interfere with the shunt pipes.

[0013] The scattered drain pipe out of the wall includes a horizontal pipe and an inclined pipe. The horizontal pipe is used to connect the water collecting port located on the roof, and the inclined pipe is used to connect the circumferential scattered drain pipes below and outside the roof.

[0014] A plurality of the circumferential scattered drain pipes arranged along the circumferential direction of the roof are connected to each other.

[0015] A plurality of the circumferential scattered drain pipes arranged along the circumferential direction of the roof are independently arranged.

[0016] Each riser pipe is formed by heightening and reconstructing the original rain and sewage combined flow riser pipe orifice on the roof.

[0017] Compared with the prior art, the utility model has the following advantages and beneficial effects: The original rain and sewage combined flow riser pipe is heightened and reconstructed to form a riser pipe for collecting domestic sewage. Rainwater flows into the scattered drain pipe out of the wall through the water collecting port and flows out through the scattered drain outflow structure below the circumferential scattered drain pipes, realizing that rainwater does not enter the riser pipe for collecting domestic sewage and having no adverse impact on the underlying building.
