摘要

A flexible spiral tube for water supply and drain pipes and cable pipes is provided to construct the flexible spiral tube conveniently without additional elbows by reinforcing stress against earth pressure and restricting breakage or deformation against external pressure. Reinforcing bars(12) are arranged outside an inner part(20) of a spiral tube(11), and recessed parts(13) and reinforcing holes(22) are arranged alternately in the spiral tube. The spiral tube is surrounded by an outer wall(25), and the inner part of the reinforcing hole is spirally wound by a flexible groove. The outer wall of the recessed part is spirally wound by a flexible groove(26). The flexible grooves are alternately formed in the inner part and the outer wall of the spiral tube. A flexible rib is formed in the flexible groove of the reinforcing hole and bent downward. A flexible rib is formed in the flexible groove of the recessed part and bent upward.
