ている。 For example, if an excavation hole is formed in the road to repair a fluid transport pipe buried underground, when the construction work scheduled for the day is completed or interrupted, the hole will be excavated in order to open the road and prevent danger. The hole must be temporarily filled. In the prior art, earth and sand are injected into the borehole to temporarily fill it. Therefore, in order to restart the construction work, the earth and sand in the excavation hole must be excavated to the top of the fluid transport pipe using a shovel, and then the area near the fluid transport pipe that protrudes into the excavation hole must be excavated by hand. However, it requires a great deal of effort and time.

された。 Referring to FIG. 2, a single rectangular parallelepiped 5 is shown. The rectangular parallelepiped 5 is made of a foamed synthetic resin material such as polystyrene or polyvinyl chloride. This rectangular parallelepiped is made by foaming a synthetic resin material with a specific gravity of about 1.04 to 10 to 15 times the size, and by foaming in this way, the specific gravity becomes 0.08. Such a rectangular parallelepiped 5 can be formed into an appropriate size and assembled together, or cut and formed at the construction site with a saw or an energized heating wire.
It is also noticeably lighter. Moreover, according to experiments conducted by the inventor of the present invention, it was confirmed that the material has sufficient strength to not deform or break even under a pressing force of 10 kg/cm 2 .

The strength is selected so that it will not deform even under a pressing force of cm 2 .
流体輸送管３の補修工事を再開するにあたつて

開いたりすることができる。 FIG. 3 is a sectional view for explaining another embodiment of the present invention. In this embodiment, a small amount of earth and sand 6 is placed on top of a rectangular parallelepiped 5 stacked in an excavated hole 4, and a paving layer 7 of asphalt or the like is formed on this earth and sand 6. When the construction work is restarted, the pavement layer 7 and earth and sand 6 are removed, and the rectangular parallelepiped 5 is removed. By such easy work, the excavation hole 4 can be filled,
You can open it.

とした。 According to experiments conducted by the inventor of the present invention, an excavation hole with a depth of 1 m is made using a rectangular parallelepiped 5 (see Fig. 2) whose horizontal length a = 30 cm, vertical length b = 50 cm, and thickness c = 30 cm. Laminate within 4. The horizontal length of this drilling hole 4 is 60
cm, and the length in the vertical direction is 1 m. The upper part of the stacked rectangular parallelepiped 5 is filled with earth and sand 6 as shown in Fig. 3.
and forming a pavement layer 7. Temporarily buried excavation hole 4
Above, a 4-ton dump truck was loaded with earth and sand.
After 300 passes, the upper part of the borehole 4 sank only 1 cm, confirming that it could be used for practical purposes. The excavated hole 4 temporarily buried in this way can be opened in about 5 to 10 minutes, and the workability is extremely good. Similar boreholes required 30 to 40 minutes of hard labor to fill and open with earth and sand as in the prior art described above.
