Description

Municipal drainage pipe

Technical Field

The utility model belongs to a municipal administration drain pipe.

Background

The conventional municipal drainage pipe is generally buried, a drainage pipeline is formed by connecting a plurality of sections of same drainage pipes, in actual long-term application, the drainage of a corresponding drainage pipe is not smooth due to the blockage of a certain section of drainage pipe, or the drainage pipe is pressed by heavy machinery on the road surface, when other lines are buried, the buried drainage pipe is broken by excavator type engineering machinery, particularly, due to rainstorm caused by typhoon, rainwater which rushes to flow downwards brings branches, leaves and road surface garbage into the drainage pipe, more serious blockage problems are easily caused, when the condition is repaired, municipal engineering teams generally detect the position of the damaged drainage pipe, close valves at the upper end and the lower end of the damaged drainage pipe, dig the road surface after the valve is closed, and replace the damaged drainage pipe. However, similar engineering operations are difficult to solve in a short time, and often require several hours or even more than ten hours, so that the drainage area of the relevant corresponding drainage pipeline is overflowed with waste water and cannot be circulated, and meanwhile, the arrangement of the emergency plan for temporary communication drainage is not preset in advance in the municipal drainage pipe arrangement of most of medium and small cities at present.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide a municipal drainage pipe, contain the drain pipe body, the pipe main part both ends of drain pipe body respectively establish flange, and the spare flange of pipeline intercommunication is established to the circumference wall of pipe main part, and bridging flange and spare flange are connected, connect back pipe main part and bridging flange and the equal inner chamber intercommunication of spare flange and form the runner, and it is closed that bridging flange is closed with sealed lid in the daily application, the utility model discloses increased the flange of external connection, conventional closure takes place that the runner blocks up or damaged and the maintenance change time is longer in torrential rain or certain drain pipe, can external drain pipe temporarily solve the problem of drainage.

In order to achieve the above purpose, the technical scheme of the utility model is that: the municipal drainage pipe comprises a drainage pipe body, wherein two ends of a pipe main body of the drainage pipe body are respectively provided with a connecting flange; the peripheral wall of the pipe main body is provided with a standby flange communicated with a pipeline, the bridging flange is connected with the standby flange, a sealing gasket is arranged between the connecting surfaces, and the connected pipe main body is communicated with the inner cavities of the bridging flange and the standby flange to form a flow channel; the upper opening of the bridging flange is connected with the sealing cover, and a sealing gasket is arranged between the connecting surfaces.

The utility model has the advantages that: the utility model discloses increased the flange of circumscribed, the conventionality is closed, takes place the torrential rain or the runner blocks up in certain drain pipe or damaged and the maintenance change time longer, can interim external drain pipe solve the problem of drainage.

Drawings

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

fig. 2 is a connection diagram of the application of fig. 1.

In the figure: the drain pipe comprises a drain pipe body 1, a pipe body 2, a spare flange 201, a bridging flange 202, a sealing cover 203, a connecting flange 204, a sealing gasket 205, a adjacent drain pipe 1001, a connecting drain pipe 1002 and a broken or blocked end 1003.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1, a municipal drainage pipe comprises a drainage pipe body 1, wherein two ends of the pipe body 2 are respectively provided with a connecting flange 204, the circumferential wall of the pipe body 2 is externally provided with a standby flange 201 communicated with an inner pipeline, the upper end of the standby flange 201 is provided with a bridging flange 202 to increase the height, so that the subsequent temporary connection is convenient, and the inner cavities of the connected pipe body 2, the bridging flange 202 and the standby flange 201 are communicated to form a flow channel; sealed lid 203 is connected to bridging flange 202 suitable for reading and establish sealed pad 205 between connecting the face, the utility model discloses increased circumscribed flange, conventional closure takes place the interior runner of heavy rain or certain drain pipe and blocks up or damaged and maintain when change time longer, can interim external drain pipe solution drainage's problem.

In practical application, as shown in fig. 2, a connecting drainage pipe 1002 without an external connecting flange 204 is connected between two drainage pipe bodies 1, the connecting drainage pipe 1002 can be installed in a plurality of pieces according to actual field, a space of 0.5 cubic meter is reserved at the underground position of the connecting flange 204 of the drainage pipe body 1 for subsequent operation, the upper opening of the space is flush with the ground and covers the panel installed in the manhole cover plate, the connecting structure forms a whole buried municipal drainage pipeline, when a certain drainage pipe body 1 or connecting drainage pipe 1002 is blocked or damaged by accident and needs to be dredged or replaced, the drainage pipe body 1 with the damaged or blocked end 1003 or the valve adjacent to the upper end and the lower end of the connecting drainage pipe 1002 is closed, the panel with the reserved space of the spare flange 201 of the drainage pipe body 1 with the damaged or blocked end 1003 and the lower end adjacent is opened, and the sealing cover 203 at the upper opening of the bridging flange 202 is opened, the two ends of the adjacent drainage pipe 1001 are respectively connected with the upper ends of the bridging flanges 202 at the upper ends of the standby flanges 201 of the drainage pipe bodies 1 adjacent to the upper end and the lower end of the damaged or blocked end 1003, and the drainage pipe bodies 1 adjacent to the upper end and the lower end of the damaged or blocked end 1003 form a temporary drainage pipeline to form a new temporary drainage channel, so that the municipal drainage problem during the factory maintenance is temporarily solved.

The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. The technical personnel of this trade also know, the utility model discloses do not receive the restriction of above-mentioned embodiment case, the description is only illustrated in above-mentioned embodiment case and the description the principle of the utility model, do not keeping away from the utility model discloses under the design category prerequisite, the utility model discloses still can have various changes and improvement, these changes and improvement all fall into the protection of claim the within range of the utility model.
