Description

technical field

[0001] The present invention relates to pipe joints for connecting pipes for protection such as wires or cables. Background technique

[0002] Since the pipe body is buried underground, it needs to be waterproof. Therefore, isolation and waterproofing as shown in Figure 5 must be applied between the pipe joint and the pipe body. 5 shows a joint 101 of various kinds of pipes made of synthetic rubber. First, a corrugated synthetic resin pipe 102 provided with a helical protrusion 102a on the peripheral surface is screwed into one side of the pipe joint 101. Then, the pipe 103 which is not provided with a protrusion on the peripheral surface is inserted into the other side of the pipe joint 101 and fastened with the band 104 . Next, the sealing tape 105 is pasted and wound on the corrugated pipe 102 side of the pipe joint 101, the watertight protection tape 106 is firmly wound thereon, and the winding end portion of the watertight protection tape 106 is crimped...
