THE STRUCTURE DUPLICATION PIPE OF WATER WORKS

摘要

The present invention relates to a double pipe structure for water. ; In particular, the present invention There is a side flange is formed with a connector of the semi-circular insert groove provided, the other flange has high strength and impact resistant PVC pipe that has been grooved installation; On one side to form a capping position inserted into the mounting groove, front and is formed with a flange fastening holes are formed at equal intervals, the other side and the coupling groove is formed at the front end, the presence of high-density rigid PVC stretch flexible tubes and bellows are manufactured by; Above, forming a capping position to be inserted in the installation groove, is formed with fastening holes at equal intervals, and the front, bottom and integrally includes a connecting member is formed with coupling projections which can take the insert coupling to the coupling groove that is configured with its features. ; This is to be achieved easily and quickly to connect the construction of the water supply pipe via the above-described configuration, it is possible to easily make the cleaning of the water supply tube to supply clean constant and, even if the crack life to the tube or a change occurs in the connection state is, and to prevent the phenomenon that leakage is caused.
