Description

Apparatus for cleaning hard cohesion matters in waterworks and sewerage}

The present invention relates to a device for removing substances deposited and attached to the water supply and drainage pipe, and more specifically, the water and sewage provided with a rotating blade to dredge the sediment solidified as a long-term sediment as well as general sediment through crushing. The present invention relates to an attachment customs device.

Dirt mixed with sewage in sewage pipes easily accumulate in stagnant sections of sewage pipes and gradually block the sewage pipes as time passes to hinder the flow of water. If the sewer pipe is gradually blocked, the internal pressure of the pipe increases due to the reduction of the sewer pipe cross section, which causes sewage to leak out of the gaps such as pipe joints and cracks, and contaminate the soil as well as the groundwater. In order to prevent such a risk, it is necessary to periodically clean the sewer pipe so as not to disturb the flow of sewage.

By the way, sediment such as soil, sludge, etc., which is not hardened in cleaning sewage pipes, could be dredged by existing dredging device, but solid deposits such as solidified sediment or cement pool due to long-term sedimentation are dredged. I could not. In other words, the existing dredging device advances to the reaction force by high pressure injection of water and simultaneously performs dredging by depositing sediment to inverter using the kinetic energy of the sprayed water. In this case, there was a problem that dredging could not proceed further to the sediment side.

Therefore, the excavation work should be carried out to remove the solid sediment in the sewage pipe, or if the excavation work is not possible due to the facility on the ground of the sewage pipe, a new sewage pipe should be established, which is expensive to remove the solid sediment in the sewage pipe. The problem was that the work was complicated and messy.

The present invention has been made to solve the above problems, by making the head rotating portion provided with a plurality of cemented carbide bits at the forward end of the device, even if the device meets the solid deposits while advancing in the sewer pipe, It is an object of the present invention to provide a water and sewage solid attachment customs device having high working speed and efficiency, by allowing bits of the rotating head rotating part to crush sediments, thereby simultaneously performing crushing and advancing.
