SAFETY DEVICE FOR WATER-TIGHTNESS TEST OF SYNTHETIC RESIN CORRUGATED PIPE

摘要

The disclosed in the present invention is a safety device for water-tightness test of a synthetic resin corrugated pipe in which a packer used to seal the water-tightness test section of the synthetic resin corrugated pipe prevents the synthetic resin corrugated pipe from being rapidly discharged to the outside by pneumatic pressure inside the synthetic resin corrugated pipe and which can be easily and quickly detached from or attached to the synthetic resin corrugated pipe. The safety device for water-tightness test of a synthetic resin corrugated pipe includes: a housing which has a through hole; a sliding block which is combined to the housing through sliding, has a plurality of connection grooves, and has a through hole concentric with the through hole of the housing; and a support bar which is connected to the plurality of the connection grooves to be rotatable, rotates to be unfolded to the outside of the housing if the sliding block protrudes to the outside of the housing, is supported on the inner circumferential surface of the curved part of the synthetic resin corrugated pipe, and rotates to be inserted into the connection grooves by being pressed by the housing if the sliding block is inserted into the housing.;COPYRIGHT KIPO 2016
