Description

Sealed connection device for fume pipe

The present invention relates to a hermetic connection device for a pipe member, and more particularly, to a hermetic connection device for connecting a fume pipe used as a sewage pipe without leakage of a joint.

Generally, water and sewage pipes are pipes for supplying water used in homes and buildings, and pipes for purifying sewage or rainwater discharged after being used from homes and buildings, and sent to the terminal treatment plant for discharge into rivers. It is made of and buried underground.

This water and sewage pipe is mainly composed of a cylindrical basket or a cylindrical assembly assembled into a steel frame, made of a fume pipe formed by rotating at high speed by adding concrete.

Since the fume pipe is made of rigid material with no flexibility, it is most important to prevent leakage of the joint. Therefore, a closed connection device for a fume pipe is installed around the joint of the fume pipe to seal the fume pipe without leakage.

As an example of such a hermetic connection device for a fume pipe, Korean Patent Publication No. 10-2016-0093380 (published Aug. 8, 2016) is provided with a first expansion pipe at an end portion of a first straight pipe and is made of cement or concrete. The sewage pipe is provided with a second expansion pipe portion at the end of the second straight pipe portion is a connecting structure for water and sewage pipe that connects the second water and sewage pipe made of cement or concrete by inserting the first straight pipe portion into the second expansion pipe portion, the first A sealing ring member inserted between an outer circumferential surface of the straight pipe portion and an inner circumferential surface of the second expansion pipe portion, and a sealing cover tube member formed of an elastic material surrounding the end side portion of the first straight pipe portion and the outer circumferential surface of the second expansion pipe portion. And, the connecting structure for water and sewage pipe is characterized in that it comprises a tube fixing band member surrounding each end side of the sealing cover tube member.
