It is possible to prevent the flowing water from being obstructed when the water flows through the water channel 8.

  As shown in FIG. 15, in the second installation step, the installation method of the grooved connector assembly to which the present invention is applied is based on either the upstream side grooved member 3 or the downstream side grooved member 4 fitted in the ground groove 7. Even if the universal joint 5 has a predetermined rigidity by using the universal joint 5 as a point of action and the other side of the upstream side groove member 3 or the downstream side groove member 4 as a power point, the upstream side groove member 3 and the downstream groove member 4 can be easily bent in the horizontal direction.

It is possible to construct the water channel 8 by bending it. In addition, as shown in FIG. 19 (b), the installation method of the grooved rod connecting body to which the present invention is applied is configured such that the upstream grooved member 3 and the downstream grooved member 4 are relatively relative to each other in the vertical direction Y. It becomes possible to be bent. Furthermore, as shown in FIG. 19 (c), the installation method of the groove / groove assembly to which the present invention is applied is bent three-dimensionally in the combined direction of the height direction Y which is the horizontal direction and the width direction Z which is the vertical direction. Thus, the water channel 8 can be constructed with a flexible angle of the bent portion.

  The groove / rod connecting body 1 to which the present invention is applied can cause the relative bending deformation of the upstream groove / rod member 3 and the downstream groove / rod member 4 even when an external force due to landslide or earthquake acts on the water channel 8. It is possible to prevent the water channel 8 from being damaged. Moreover, according to the situation of the site where the water channel 8 is constructed, the grooved connector assembly 1 to which the present invention is applied can bend the upstream grooved member 3 and the downstream grooved member 4 relatively freely, Since it is not necessary to change the angle for each bending angle, it is possible to manufacture with a short delivery time while suppressing the manufacturing cost.

  As mentioned above, although the example of embodiment of this invention was demonstrated in detail, all the embodiment mentioned above showed only the example of actualization in implementing this invention, and these are the technical aspects of this invention. The range should not be construed as limiting.
