題が生じることがある。The pipe pillow 12 has a different size depending on the diameter of the pipe 10, and is designed so that the gap between the upper, lower, left and right pipes becomes constant when the pipes having the same diameter are buried. Therefore, when the pipes are made up of pipes of the same diameter, the intervals between the pipes are kept constant, so that when backfilling, sand enters vertically between the pipes, and the filling pressure is also sufficiently effective. be able to. But Figure 7
When burying pipes having different diameters as described above, the gap between the pipes arranged in the lower stage and the gap between the pipes arranged in the upper stage are laterally displaced, so that the sand for backfilling is filled with the arrow S. As it goes diagonally like this, it is difficult to fill between the pipes and it becomes difficult to apply pressure. As a result, there may be a problem that the road below the pipe is not sufficiently filled with sand and the road on the pipe line is depressed after backfilling.

付して説明を省略する。[Third Embodiment] FIG. 6 shows another embodiment of the lower half member and the upper half member that constitute the tube pillow. Although only the lower half member 13A is shown in FIG. 6, the upper half member 13A is shown.
B also has the same structure except that it is turned upside down.
The lower half member 13A is different from that of FIG. 2 in that a slide convex portion 30 and a slide concave portion 32 extending in the tube axis direction are formed on the lower surface at positions symmetrical with respect to the center in the width direction. . When the tube pillows are stacked, the slide protrusions 30 and the slide recesses 32 are slidably engaged with the slide recesses and slide protrusions of the other party in the axial direction of the pipe, thereby forming an upper half member of the lower pipe pillow. This is the part that connects the lower half members of the upper tube pillow. The distance W between the slide convex portion 30 and the slide concave portion 32 is set to be constant regardless of the size of the tube pillow. Even with such a configuration, when the tube pillows 12 having different diameters are stacked as shown in FIG. 1, the central axes of the tube holding portions 14 can be aligned vertically. Since the configuration other than the above is the same as that of FIG. 2, the same portions are denoted by the same reference numerals and the description thereof will be omitted.

【発明の効果】 以上説明したように本発明によれば、
径の異なる管を複数列複数段に配管して地中埋設する場
合に、管の間の隙間が上下方向に揃うようになるので、
埋め戻しの際に、管の間の隙間に砂を充填しやすくなる
と共に、填圧も効きやすくなる。したがって施工後に地
表面が陥没するようなことをなくすことができる。As described above, according to the present invention,
When pipes with different diameters are piped in multiple rows and multiple stages and buried underground, the gaps between the pipes will be aligned vertically,
When backfilling, it becomes easier to fill the gaps between the pipes with sand, and also the pressure filling becomes more effective. Therefore, it is possible to prevent the ground surface from sinking after the construction.
