Abstract

The utility model discloses an urban sewer, which comprises an inner-layer pipeline (3), and an outer-layer pipeline (1) and a middle-layer pipeline (2) which are sequentially sleeved outside the inner-layer pipeline (3), wherein the outer-layer pipeline (1), the middle-layer pipeline (2) and the inner-layer pipeline (3) are circular pipelines of which the centers of the three pipelines coincide, gaps exist between the middle-layer pipeline (2) and the outer-layer pipeline (1) as well as between the middle-layer pipeline (2) and the inner-layer pipeline (3), the gaps constitute drain passages, and the walls of the middle-layer pipeline (2) and the inner-layer pipeline (3) are respectively provided with at least one pressure relief valve (4). Through the method, the urban sewer provided by the utility model has the advantages of novel structure, good drainage effect and the like.

Description

A kind of urban discharging pipeline

Technical field

The utility model relates to gutter field, particularly relates to a kind of urban discharging pipeline.

Background technology

Along with expanding economy, the deterioration of environment, extreme weather is the common phenomenon of Cheng Liao contemporary society just like, particularly some Heavy Rainfall Weathers, can make city be absorbed in serious waterlogging, and its reason is, the drainage pipe in existing city is too narrow, under the precipitation situation of burst, the displacement of pipeline is lower than inflow, thereby causes the generation of waterlogging.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of urban discharging pipeline, by multi-layer piping and relief valve are set, the drainability of pipeline is strengthened, and has the advantages such as novel structure, drainage effect are good.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of urban discharging pipeline is provided, comprise inner layer pipe and be set in successively outer layer pipe and the middle level pipeline (2) of described inner layer pipe periphery, described outer layer pipe, middle level pipeline and inner layer pipe are the circular pipe that the center of circle overlaps, between described middle level pipeline and outer layer pipe and inner layer pipe, all there is gap, described gap forms drainage channel, is equipped with at least one relief valve on the tube wall of described middle level pipeline and inner layer pipe.

In preferred embodiment of the utility model, described relief valve is arranged on the top of described middle level pipeline and inner layer pipe tube wall.

In preferred embodiment of the utility model, the material of described outer layer pipe, middle level pipeline and inner layer pipe is concrete, metal or plastics.

The beneficial effects of the utility model are: the utility model urban discharging pipeline is by arranging multi-layer piping and relief valve, and the drainability of pipeline is strengthened, and have the advantages such as novel structure, drainage effect are good.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:

Fig. 1 is the structural representation of a kind of urban discharging pipeline one preferred embodiment of the utility model.

In accompanying drawing, the mark of each parts is as follows: 1, outer layer pipe, 2, middle level pipeline, 3, inner layer pipe, 4, relief valve.

The specific embodiment

Below the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, the utility model embodiment comprises:

A kind of urban discharging pipeline, comprise inner layer pipe 3 and be set in successively outer layer pipe 1 and the middle level pipeline 2 of described inner layer pipe 3 peripheries, the circular pipe that described outer layer pipe 1, middle level pipeline 2 and inner layer pipe 3 overlap for the center of circle, between described middle level pipeline 2 and outer layer pipe 1 and inner layer pipe 3, all there is gap, described gap forms drainage channel, is equipped with at least one relief valve 4 on the tube wall of described middle level pipeline 2 and inner layer pipe 3.

Described relief valve 4 is arranged on the top of described middle level pipeline 2 and inner layer pipe 3 tube walls, and pressure release is effective.

The material of described outer layer pipe 1, middle level pipeline 2 and inner layer pipe 3 is concrete, metal or plastics.

The beneficial effect of the utility model urban discharging pipeline is:

By multi-layer piping and relief valve are set, the drainability of pipeline is strengthened, there is the advantages such as novel structure, drainage effect are good.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
