A Corrugated Steel Pipe Device With A Gasket Of Flange Type For Changing Joining-Angle Easily

摘要

The present design makes the joint state and the watertight maintenance state solid during the pipe joint construction, and has a flange-type gasket to facilitate the change of the joint angle with the function of changing the joint angle so that the joint angle can be easily adjusted. It relates to a steel pipe device, and is buried in the basement of the corrugated steel pipe of a predetermined length in which the waste water flows into the inner side, and close to the edge of the corrugated steel pipes to be kept watertight, the inner circumference is connected, the outer circumference is separated The coupling portion is provided so that the first gasket and the corrugated steel pipe interposed therebetween are inserted into the outer circumference of the first gasket and the separated first gasket, which may be coupled around the first gasket and the second gasket. It is made to include.
