JPH09182267A - Device for joining hand hole with conduit material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the damage of a variety of cables, etc., by providing a joint member which absorbs horizontal force between a hand hole and a conduit material, covering the section of a joint material with a portal protective material without performing backfililng. SOLUTION: A port 15 being widened in communication with a port 14 is provided at the end of a perforated pipe 13. A connection pipe 16 is set in the port 15 through an O ring 17. The other ends of the connection pipes 16 are set severally freely of sliding on the inner faces of the pipes that they confront. For the connection pipe 16, a flexible joint 16a may be interposed in the middle. Above and on both sides of the pipe 11 and the connection pipe 16, space part 19 covered with a portal protective material 18 is provided. The space part 19 is made not to hinder the mutual sliding action of the pipe 11 and the connection pipe 16 without backfilling. When earthquake, etc., occur, for the hand hole 10 and the perforated pipe 13, the pipe 11 and the connection pipe 16 set freely in the pipe 11, by sliding in horizontal direction within the pipe 11, absorb the motion.

As shown in the figure, the long bell mouth 23 shown in FIG. 4 is formed so as to be slidable left and right along the inner side surface of the rubber packing 22 as described above. The outer surface of the tip of the above is loosely fitted to the inner surface of the connecting pipe 25, and the connecting pipe 25 is fitted and fixed to the hole portion 15 which is opened by communicating with the hole 14 of the perforated pipe 13. In addition, the portion where the long bell mouth 23 is loosely fitted is formed to have a large diameter so that they can slide with respect to each other. Therefore, in this case, the sliding action of the long bell mouth 23 itself and the sliding action of the long bell mouth 23 and the connecting pipe 25 are combined, and the sliding action is added, resulting in an earthquake. At times, the horizontal force can be sufficiently absorbed as in the embodiment of FIGS. 1, 4 and 5.

る。As described in detail in the above embodiment, the joining device for handholes and conduits according to the present invention allows mutual movement between the handholes and conduits made of perforated pipes, especially Since a joint member is provided to absorb horizontal force, and the space of this joint member is covered with a gate-shaped protective member to form a space without backfilling, a earthquake occurs, for example. However, even if horizontal forces that mutually interfere with each other are applied to the handhole and the pipeline material, the sliding action of the joint member is smoothly performed. Horizontal movement is absorbed. Thus, the mutual damage caused by the mutual interference at the joint portion of the handhole and the pipeline is minimized, and the electric wires and other facilities housed in the handhole and the pipeline are installed. This is an invention that has a very significant effect, such as that restoration can be performed easily and quickly because the effect on the can be reduced as much as possible.
