In order to solve the above problem, the foreign material accumulated in the sewage pipe 6, the sewage, and the rain receiver 3 is dredged.

That is, since the dredging of the sewer pipe 6 has a large diameter of the sewer pipe 6 and is formed in a straight line, the dredging device is easily introduced into the sewer pipe 6 to remove foreign substances. The rain catcher 3 opens the lid 4 and removes foreign matter accumulated in the rain catcher 3 by shoveling it. However, since the connecting pipe 5 is not only small in diameter and short in length, but also narrow in width, it is connected to one side of the rainwater receiver 3 so that a known dredging device cannot be introduced into the connecting pipe 5. The foreign matter accumulated in the connecting pipe 5 is left unattended in a state of dredging, and thus, the connection pipe 5 is blocked, causing a problem of flooding roads and houses.

The present invention has been made in order to solve the above problems, by dredging the foreign matter, such as earth and sand accumulated in the connection pipe installed between the rain, rainwater receiving and sewage pipes dredged on the road so that rainwater or sewage is quickly discharged The purpose of the present invention is to provide dredging devices and methods for drainage of storm drains to prevent flooding of houses.
