Description

Intercommunication type sewer arrangement structure

Technical Field

The utility model belongs to the technical field of municipal works technical field of the municipal works structure and specifically relates to an intercommunication formula sewer arrangement structure.

Background

In municipal works, sewer pipes are criss-cross and respectively lead to different outlets, but once one of the pipelines is blocked or unsmooth in circulation, sewage overflows and overflows outwards from a well cover, so that the city appearance is seriously influenced, surrounding pedestrians and living environments are polluted, and the road safety of the pedestrians is influenced sometimes.

Disclosure of Invention

The utility model aims at providing an intercommunication formula sewer arrangement structure to above-mentioned condition, this sewer arrangement structure improves simply, and the construction is not complicated, nevertheless is very obvious to the effect of the overflow that prevents of sewer, has fine in-service use and worth.

The utility model has the following concrete scheme: the utility model provides an intercommunication formula sewer arrangement structure, has the sewer well of vertical arrangement and distributes a plurality of horizontal sewers around the sewer well, and the below intercommunication of sewer well has a main sewer, installs the well lid on the sewer well, all communicates to each horizontal sewer on every side on the wall of a well all around on the wall of a well of sewer well and has connect an overflow passageway, overflow passageway's road junction is arranged in the top of main sewer.

Further, in the present invention, the overflow passage is perpendicularly arranged and connected with the corresponding horizontal sewer when viewed from the top.

Further, in the utility model, the overflow channel is formed by two overflow branch pipes arranged in an inverted V shape, the included angle between the two branch pipes is α, wherein α is more than or equal to 135 degrees and is less than or equal to 165 degrees.

Furthermore, the utility model discloses well two overflows and divide the inside juncture between the pipe still to be equipped with a filter screen.

The utility model discloses a to current sewer arrangement structure improve, fine solution a problem of the refluence overflow that appears under the not smooth condition of horizontal sewer circulation, greatly reduced the well lid overflow to pedestrian and the harmful effects that the municipal administration brought on every side, fine in-service use and spreading value have.

Drawings

Fig. 1 is a schematic view of the top view structure of the present invention;

FIG. 2 is a schematic sectional structure of the present invention;

fig. 3 is a schematic diagram of the structure of the overflow passage of the present invention.

In the figure: the method comprises the following steps of 1-a well cover, 2-an overflow channel, 3-a transverse sewer, 4-a main sewer, 5-a drainage well, 6-an overflow branch pipe and 7-a filter screen.

Detailed Description

Referring to fig. 1-3, the utility model relates to an intercommunication formula sewer arrangement structure has the lower well 5 of vertical arrangement and a plurality of horizontal sewer 3 of distribution around the lower well, and the below intercommunication of lower well has a main sewer 4, installs well lid 1 on the lower well, all communicates to each horizontal sewer on every side respectively on the wall of a well all around of lower well and has connect an overflow passageway 2, the top at main sewer is arranged to overflow passageway's road junction.

Further, the overflow channel in this embodiment is vertically arranged and connected with the corresponding lateral sewer as seen from the top.

Further, the overflow channel in this embodiment is composed of two overflow branch pipes 6 arranged in an inverted V shape, and the included angle between the two branch pipes is α, wherein 135 ° or more and α or less and 165 ° or less, and the angle here is not too large or too small, and preferably 150 ° is suitable.

Furthermore, in this embodiment, a filter screen 7 is installed at the inner junction between the two overflow branch pipes.

When the sewer structure of the utility model is constructed, the overflow channel is built from the well wall of the sewer well to the adjacent transverse sewer according to the distribution trend condition of each transverse sewer around the sewer well, and the overflow channel is vertically built with the transverse sewer from the overlooking direction when being built, so that the length of the overflow channel can be reduced as much as possible, and the effect of accelerating drainage overflow is obvious; meanwhile, the overflow channel is constructed into an inverted V-shaped structure which is arched upwards during construction, so that the overflow of water in the sewer well to an adjacent transverse sewer can be ensured only after the water rises to a certain height, and the overflow can not overflow outwards from the well cover.

In the structure, the V-shaped node of the overflow channel is also provided with the filter screen, which is mainly used for preventing sundries from flowing to the adjacent transverse sewer and further blocking other sewers.

The utility model discloses the structure is particularly suitable for that kind of horizontal sewer is personally submitted the sewer of layered form (not on same horizontal layer promptly) design under the earth's surface, more is favorable to taking place the overflow in the sewer of sewage to the next door under the jam condition, reaches the purpose of better mediation offal, and this is especially important to municipal works's design.

Claims (4)
