Abstract

PURPOSE: To facilitate intake of deep layer water by arranging an inner pipe in the interior of an outer pipe via space supporting stays made of flexible materials and making at least one from the group of the outer pipe and inner pipe with water permeable material. CONSTITUTION: An inner pipe 2 having a diameter smaller than that of an outer pipe 1 is arranged in the interior of the outer pipe, and space maintaining stays are arranged in the space between the inner wall of the outer pipe 1 and the outer wall of the inner pipe 2. The outer pipe 1, inner pipe 2 and the space maintaining stays 3 are made of flexible materials such as flexible plastic or cloth. At least one from the group of the outer pipe 1 and inner pipe 2 are made of water permeable materials such as cloth. The space 4 may preferably be filled with sand, grit or granular fillers. As a result, the pipe is suitable for intake of deep layer water and will not be damaged by waves and the like.
