Description

Dark sewage of culvert is held back and is collected structure

Technical Field

The utility model relates to a secretly contain sewage and hold back collection structure is applicable to the municipal works secretly contain in and cut dirty pipe and lay the field.

Background

Along with the development of urbanization, the rain and sewage diversion project is widely developed nationwide. Especially, in the process of laying the sewage intercepting pipe in the hidden culvert, the sewage intercepting pipe intercepts sewage on two sides along the box culvert so as to ensure that no sewage flows into the culvert, and the box culvert is kept in a dry state in dry seasons. Once arrived evening with water peak period, often can't satisfy the too big water yield along the line and gush into, cause sewage to overflow from the inspection shaft, lead to black smelly water body to produce in the box culvert, consequently need take special measure to overflow sewage and handle, otherwise be difficult to eliminate black smelly water body.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: to above-mentioned sewage overflow problem, provide a sewage and hold back collection structure in the dark culvert to prevent that the water peak period from, cause sewage to overflow from the inspection shaft, lead to the problem that black and odorous water body produced in the box culvert. Therefore, the utility model adopts the following technical scheme:

a sewage interception and collection structure of a hidden culvert is characterized in that an inspection well is arranged in the hidden culvert; the inspection well is characterized in that a water collecting tank is arranged beside the inspection well at the bottom of the hidden culvert and used for collecting overflow of the inspection well, the water collecting tank is connected with overflow sewage branch pipes, and the overflow sewage branch pipes are connected with an overflow sewage main pipe.

Furthermore, the overflow sewage branch pipe and the overflow sewage main pipe are arranged on the bottom surface of the concealed culvert, the cover layers of the overflow sewage branch pipe and the overflow sewage main pipe are arranged on the bottom surface of the concealed culvert, and the water collecting tank is arranged on the side edge of the cover layers.

Further, the covering layer sequentially comprises a graded broken stone cushion layer, geotextile and a medium-coarse sand layer from bottom to top; the overflow sewage branch pipe and the overflow sewage main pipe are buried in the graded broken stone cushion layer.

Further, the water collecting tank is coated with waterproof mortar.

Further, the overflow sewage main pipe is communicated to a sewage pumping station.

Furthermore, the sewage discharge pipeline along the line is connected to an inspection well, and the inspection well is connected with a sewage main pipe.

The utility model discloses can solve the sewage in the dark culvert and hold back the collection structure, can guarantee that overflow sewage can't directly get into in the culvert, make it flow in newly-built overflow sewage pipe, guarantee to contain interior no sewage runoff, alleviate black and odorous water condition in the culvert widely, alleviate black and odorous water to all ring edge borders and resident's influence. The utility model discloses still solve laying and flood control protection that overflow sewage branch pipe and overflow sewage were responsible for through sponge city means, reduce engineering volume, reduce cost to make the structure keep natural visual effect.

Detailed Description

Reference is made to the accompanying drawings. The utility model provides a hidden culvert sewage interception and collection structure, wherein an inspection well 200 is arranged in a hidden culvert 100; the sewage pipes are connected to the inspection well 200 along the line, and the inspection well 200 is connected with the sewage main pipe.

The inspection well 200 is by setting up water catch bowl 1 in dark culvert bottom for collect the overflow of inspection well 200, for example, in evening with the peak period of water, cut dirty pipe along the line can't satisfy the water that the sewage that causes gushes in and from the inspection well overflow. The water collecting tank 1 is connected with an overflow sewage branch pipe 2, the overflow sewage branch pipe 2 is connected with an overflow sewage main pipe 3, the overflow sewage main pipe 3 is communicated to a sewage pump station, and finally the overflow sewage is connected to a downstream sewage treatment plant for treatment. The overflow sewage branch pipe 2 and the overflow sewage main pipe 3 can adopt PVC-UH pipes.

The overflow sewage branch pipes 2 and the overflow sewage main pipe 3 are arranged on the hidden culvert bottom surface 101, and the water collecting tank 1 is arranged on the side edge of the covering layer.

The covering layer is sequentially provided with a graded broken stone cushion layer 41, a geotextile 42 and a medium-coarse sand layer 43 from bottom to top; the overflow sewage branch pipes 2 and the overflow sewage main pipe 3 are buried in the graded broken stone mat 41. Graded broken stone bedding course 41 plays supporting and cushioning effect, and geotechnological cloth 42 covers and has played the protection graded broken stone, has blockked the effect that silt sinks to block up its space at graded broken stone bedding course 41, well coarse sand layer 43 has played the effect of fixed geotechnological cloth and has provided natural visual effect. Through this kind of sponge city structure, can protect overflow sewage branch pipe 2 and overflow sewage person in charge 3 effectively to reduce the engineering volume, reduce cost, simultaneously, still make the structure keep natural visual effect.

The water collecting tank 1 is coated with waterproof mortar.

In the water peak period, if sewage overflows from an inspection wellhead, the sewage can fall into the water collecting tank 1 arranged in the culvert, overflow sewage collected by the water collecting tank 1 enters the overflow sewage branch pipe 2, and the overflow sewage enters the overflow sewage main pipe 3 through the overflow sewage branch pipe 2 and finally flows into a downstream sewage pump station.

The utility model is suitable for an among the sewage intercepting pipe laying treatment engineering along the line in all secret cities dark culverts, for preventing that the sewage overflow from getting into leading to in the dark culvert that the dirty mixed flow of rain produces the improvement scheme of black smelly water. The improved application scheme is suitable for sewage treatment projects along the line in any underground culvert, can be improved and implemented based on the sewage interception pipe along the line, and can also be directly used for treating and implementing the discharge port along the line (the main port sewage interception pipe is connected into a sewage pipe embedded in a gravel cushion layer).

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the ordinary skilled person in the art can change, add or replace the present invention within the scope of the present invention.
