いる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a concrete water blocking wall as a structure, and a flexible connecting pipe 2 made of FRPM or the like is provided therethrough. As shown in FIG. 1 and FIG. 2, the flexible pipe 2 is not directly connected to the water blocking wall 1, but is connected to the flexible pipe 2 at a portion where the flexible pipe 2 penetrates the water blocking wall 1. A protective cylinder 3 which is slightly larger and whose width is larger than the thickness of the water blocking wall 1 in the penetrating direction is penetrated. The flexible tube 2 is disposed in the protective cylinder 3 through the cushion member 4 so as to penetrate in a substantially orthogonal posture, and the width of the cushion member 4 is larger than the thickness of the structure. Is formed. Short pipes 5A, 5B are connected before and after the flexible pipe 2 for connection, and are connected to other flexible pipes 6 forming a conduit via the short pipes 5A, 5B.

Since the flexible tube 2 for connection is connected to the water blocking wall 1 via the cushion member 4 and the protective cylinder 3, the concentrated load is alleviated by the cushion member 4 and acts on the flexible tube 2. And the flexible tube 2 is prevented from being damaged. Short pipes 5A and 5B are connected before and after the flexible pipe 2, and a connection between the flexible pipe 2 and the short pipes 5A and 5B and the short pipes 5A and 5B and other flexible pipes. 6 has flexible flexibility at the connecting portion with the flexible tube 2, so that even if local uneven settlement occurs, the flexible tube 2 for connection can be easily moved vertically with respect to the other flexible tubes 6. It can move relative to each other without damaging the flexible tube 2.

どは防止される。As described above, according to the present invention, a protective cylinder, which is slightly larger than the flexible pipe, penetrates the flexible pipe penetrating portion of the structure, and the cushion material is inserted into the protective cylinder. Since the flexible pipe is disposed through the flexible pipe, concentrated load hardly acts on the flexible pipe, and damage to the flexible pipe is prevented.
