Claims

[Scope of utility model registration request]

A large number of water holes communicating with the inside of the pipe are bored at regular intervals in the spiral direction in the spiral valley bottom of the main body of the synthetic resin pipe having spiral protrusions, and among the adjacent spiral valley bottoms, one valley bottom One water hole is located in the axial direction of the pipe between adjacent water holes drilled in the other valley, and one water hole is drilled in the other valley. A synthetic resin drain pipe characterized in that the distance between both water passage holes is equal.
