[0002]

2. Description of the Related Art Conventionally, when constructing a foundation for a house or the like, splittering and quarrying are performed. In the splittering industry, wedge-shaped splitter stones of a predetermined size are lined up on the root bottom formed on the ground surface with the sharp side down, and the splitter stones are compacted by a compacting machine . But,
Since there is a shortage of gravel and the like that can be used for split stone, there are few high quality split stones and the cost of split stone increases. For this reason, it has been difficult to obtain cracked stones of uniform size. Also, since the split stones were lined up with no gap and the sharp side down, the on-site work was difficult.

Therefore, as a method for solving these problems, a method has been proposed in which a thin film having a concave portion is laid at the root of the root, and concrete slurry is driven into the concave portion to artificially apply the split stone (Japanese Patent Application Laid-Open No. H10-157572). Kaihei 1-235727
issue).

In the crushed stone industry, crushed stone is laid at the bottom of the root, and then the crushed stone is compacted by a compacting machine such as a tire roller, and then a level check for measuring the thickness of the crushed stone is performed. These are repeated until the thickness of the crushed stone reaches a predetermined thickness.

[0005]

However, there is a problem that it is difficult to improve the work efficiency of the on-site work, since the concrete must be cast on the construction site and cured in the construction site. is there. In the crushed stone industry, the construction quality of the crushed stone is affected by the hardness of the crushed stone itself, the thickness of the crushed stone, and compaction. Cause it. In addition, since a standard is set for the hardness of the crushed stone itself, usable crushed stone is limited and costs increase. Since the crushed stone must be laid, compacted, and level checked repeatedly until the crushed stone reaches a predetermined thickness, there is a problem that it is difficult to improve the work efficiency of the on-site work.

[0006] In the quarrying industry, there is also known a method of solidifying the ground by a chemical method. This groundwork is performed by spraying the stabilizing agent on the root bottom, curing and solidifying the ground, but since the stabilizing agent must be evenly sprayed on the root bottom and cured until the strength is developed, There is a problem that it takes time for the construction of the local business.

[0007] An object of the present invention is to propose a local business member, a local business jig, and a local business method capable of improving the working efficiency of a construction site and performing local business at low cost. .
