Here, the sub-pipe (1) is not limited in its kind but may be a sub-pipe having a relatively large flow amount.

The blocking interval a is an interval required for maintenance such as maintenance and internal monitoring of the secondary pipe 1, and FIG. 1A exemplifies a section extending over two manholes 21 and 22, but the number is not limited thereto . As shown in the figure, the flow of the sewage is stopped in the blocking section (a) by blocking the sub-pipe 1 corresponding to the blocking section (a) in both directions.

Next, as shown in FIG. 1B, a pipe opening / closing valve 200 for opening and closing the downstream pipe 1 at the rear end of the front manhole 21 of the blocking section (a) is mounted. The packing up to the packing 100 mounted on the lower pipe 1 at the rear end of the rear-end manhole 22 corresponds substantially to the work section. The conduit opening / closing valve 200 controls the degree of opening and closing of the conduit so that when there is sewage flow that does not require water turning in the conduit pipe 1, the degree of opening and closing of the conduit switching valve 200 is adjusted, Allow sewage flow to the extent that it does not interfere with the operation, and prevent load by sewage resistance. Of course, in this case, the open / close valve 110 is kept open in each packing 100 to allow the sewage to flow, and the opening / closing degree of the pipe is controlled by the opening / closing valve 200, To produce a sewage flow that is insufficient.

Next, as shown in FIG. 1C, the water level raising device 300 according to the present invention is mounted on the manhole 23 at the front end of the front manhole 21 of the blocking section (a). When the amount of sewage flowing into the secondary building 1 is large, water must be turned. Therefore, it is necessary to prevent the backflow from the manholes 23 other than the blocking section (a) (300) is mounted.

Next, as shown in FIG. 1 (d), the rear manhole 22 from the outside through the front manhole 21 from the downstream side of the front manhole 21 of the blocking section a, A flow unit 400 for communicating the downstream pipe 1 at the rear end of the rear manhole 22 of the blocking section a with the packing 100 is mounted.

That is, in order to prevent the backflow of the sewage from the manholes 23 other than the blocking section (a) due to the increase of the sewage flow amount in the secondary pipe 1, the water turning is performed without affecting the work in the work section.

To this end, both ends of the flow means 400 are respectively mounted on the packing 100, and the opening and closing valve 110 of each packing 100 is opened so that the outer pipe 1 outside the work section is connected to the flow means 400 So that water can be turned while communicating. Here, it is preferable that the flow means 400 does not limit the material thereof, but it is a flexible material and a pipe for allowing the sewage to flow therein.

However, such manual turning of the water by turning the water may take a long time, so there must be a work stoppage period. That is, after the above-mentioned process, after opening and closing the conduit opening / closing valve 200, the opening / closing valve 110 of the packing 100 is opened after the flow unit 400 is separated from the packing 100 (a) to allow the sewage to flow. That is, the sewage flow of the entire secondary pipe 1 is allowed to proceed again. As a result, in the present invention, it is not necessary to dismantle the entire apparatus in the work rest period, and only the flow means 400 is disassembled, and by the simple process of opening the pipe opening / closing valve 200 and the on- Lt; RTI ID = 0.0 > flow. ≪ / RTI >
