ONE-TOUCH TYPE THREE-STAGE COUPLING DEVICE OF JOINING PIPE FOR JOINTING PRESSURE PIPES AND METHOD FOR CONSTRUCTING PRESSURE PIPES USING SAME

摘要

The present invention relates to a one-touch type three-stage coupling device of a joining pipe for jointing pressure pipes and a method for constructing pressure pipes using the same. More particularly, the present invention is characterized in that only one motion of pushing a pressure pipe into a joining pipe (J) for joining pressure pipes can lead to a completion of joining and fixing, by forming an organic coupling structure, which is composed of a ′fixing structure′; formed at a linear part (P) insertion and contact part (A) and a bushing insertion and contact part (D), a ′double friction resistant structure′ by a coupling element (20), and a ′water sealing structure′ by a water sealing rubber packing, inside the joining pipe (J) for joining pressure pipes. The coupling structure of the present invention has a one-touch type, thereby facilitating joining and connecting works and thus performing efficient connecting, and shortening the time for construction. In addition, since a pressure pipe inserting apparatus allows one-touch type joining and fixing, a worker need not directly perform a joining work, and thus a separate work excavation space is not needed, thereby achieving efficient and economical excavation.;COPYRIGHT KIPO 2014
