A corrugated hard polyethylene pipe joint and a device thereof are provided to improve a waterproof property by forming an airtight structure between a flange and a manhole. A corrugated hard polyethylene pipe joint includes a first member(10) and a second member(20) which are coupled to each other. The first member includes a first coupling unit(11), a second coupling unit(12), a flange(13), and a through unit(14). The first coupling unit protrudes to one side of a longitudinal direction of a corrugated pipe including a cable(2) inside and is coupled to a connection unit of a manhole. The second coupling unit protrudes in an opposite direction to that of the first coupling unit. The flange is formed between the first and second coupling units to be larger than the connection unit. The through unit is formed through the first coupling unit, the flange, and the second coupling unit. |
