The present invention relates to a joining pipe for jointing pressure pipes and a one-touch type coupling device for a pressure pipe joining part. More particularly, the present invention is characterized in that only one motion of pushing a pressure pipe into a joining pipe for joining pressure pipes and a pressure pipe joining part (J) 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 pressure pipe insertion and contact part and a bushing insertion and contact part, a′friction resistant structure′by an inner elastic protrusion portion (22a) and an outer elastic protrusion portion (22b), and a′water sealing structure′by a water sealing rubber packing, inside the joining pipe for joining pressure pipes and the pressure pipe joining part (J). 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. |
