Claims

[Scope of utility model registration request]

A tremie pipe used when placing underwater concrete, underwater mortar, etc., comprising a ring-shaped protrusion formed on the outer peripheral surface of both ends of the tremie pipe;
A housing having two parallel circumferential grooves that engage with the protrusions formed on the inner circumferential surface and which is divided into two in the circumferential direction or connected in one-touch, and an outer circumferential surface of the housing at the center of the inner circumferential surface of the housing.
