The present invention relates to a seal and a pipe connection socket using the seal, which allow the pipe to be easily connected at the same time, while maintaining the state of the pipe and the watertight stability.

In general, synthetic resin pipes have hollows formed therein to form double walls or triple walls, sewage pipes formed by extrusion, and water pipes formed by extrusion, and are used in various ways, such as sewage pipes and rainwater pipes.

Here, the synthetic resin tube is continuously formed, cut to a certain length due to movement and storage problems and the cut synthetic resin tube is used by connecting through a variety of connection methods.

Therefore, a synthetic resin pipe is buried underground, and at the same time, a connection structure such as a flange type, an E / F sheet, a heat shrink sheet, a KP type, a knitting pipe, a socket method, and the like has been proposed in various structures.

However, the connection method of the synthetic resin pipe using the flange type and KP type and knitting pipe takes a long time to tighten because of the use of a plurality of bolts and nuts, there was a problem that can not be fastened with a uniform force on the entire surface when tightening.

In addition, the coupling part of the connector is easily broken, and the post-processing part of the connector is weakened, which causes water leakage, and when the rubber ring is thick, it is difficult to insert the pipe, and when the rubber ring is thin, the binding force is weak, causing leakage. There was this.

In addition, the heat shrink sheet is a heat source supplied from the outside by winding the connection part of the synthetic resin pipe and integrally connected with the synthetic resin pipe, and the connection of the pipe is simple, but there is a problem that the external force is easily separated.
