The construction method of this invention comprised in this way is demonstrated.

9 to 11 are views illustrating a construction process of the present invention.

First, referring to FIG. 9, in one step, both connecting pipes 100 and 100a in which the connecting pipe 8 and the disc body 832 are inserted are embedded in the ground with a predetermined space.

Thereafter, referring to FIG. 10, as the second step, the input pipe 10 or the discharge pipe 12 is positioned in the space between the two side pipe lines 100 and 100a.

As a third step, the flange (8) is pulled so that the flange (81) abuts the flange (50, 40) of the inlet pipe 10 or the discharge pipe 12, and then tighten the bolt to connect.

Thereafter, referring to FIG. 11, the fourth step may be such that the conduits 100 and 100a have airtightness through the packing 836 at the connection part inserted into the connection pipe 8.

In the fifth step, the disk body 832 is pushed to move to the connected portions of the conduits 100 and 100a and the connection pipe 8, and then tighten the tightening bolt 834 to the bolt hole 837 of the outer ring part 835. To fix it.

After the construction is completed it will be described a washing process using the pipeline washing apparatus of the present invention.

First, shut off the flow of water by closing the valve 120 installed in the inlet pipe 100, and then open the lid 23 of the inlet 20 to put the pig (2) and close again and tighten the bolt 235 To seal.

At this time, the support plate 244 provided on the guide member 24 of the lid 23 presses the outer surface of the pig 2 so that the pig 2 may be positioned in the center of the feed tube 10.

On the other hand, the lid 23 of the outlet 22 is opened to install the discharge guide member (4).

That is, the guide member 44 of the discharge guide member 4 is inserted into the inside, and the ring 42 is seated on the rounded jaw of the outlet 22, and then the bolt 226 is fastened to fix it firmly.

Thereafter, the valve 120 on the inlet side is opened to supply water at high pressure, or air pressure at high pressure is injected into the pipe line 100 to flow into the inlet pipe 10.

The stress due to the impact generated at this time is absorbed and relieved by the expansion joint member 3 installed in the input pipe 10.

Thereafter, the pig 2 is transported by the driving force 10 and the pipeline 100 under the propulsion force, and the pig 2 fired at a high speed moves forward on the inner wall of the pipeline 100, while the foreign substances remaining on the inner wall remain. And remove scale.

Thereafter, when the pig 2 reaches the outlet 22, the pig 2 rises on the discharge guide member 4 from the tip thereof and is discharged to the outside through the outlet 22.

At this time, the water transported with the pig 2 will continue to flow through the discharge side conduit (100a) through the water outlet 45 between the guide member 44.

If the valve 120 is installed in the pipeline 100 on the outlet side, the stress due to the impact of the washing water is absorbed and relieved by the expansion joint member 3 installed in the discharge pipe 12.

Therefore, the impact applied to the joint portion of the pipeline by the expansion joint member 3 can be alleviated to prevent breakage, thereby preventing the risk of leakage.

After the washing operation of the pipe line is completed, the discharge means 6 of the input pipe 10 or the discharge pipe 12 is opened to completely remove residual water and debris remaining therein.

That is, by opening the valve 64, the residual water and the residue remaining in the collecting groove 600 can be completely discharged through the drain pipe (62).

Then, the lid 23 is coupled to the inlet 20 and the outlet 22 to seal.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, all such modifications and modifications being attached It is obvious that the claims belong to the claims.
