In the figure, reference numeral 1 denotes an auger, which is a well-known screw which is rotationally driven by a driving device 2 such as a hydraulic motor. The tip of the drilling shaft 3 is a drilling head 4, and a hardening material such as cement milk passing through the inside of the drilling shaft 3 can be injected from the drilling head 4. Although not shown, the driving device 2 is suspended from the leader mast of the base machine so as to be able to move up and down, and the excavating shaft 3 can be extended by being appropriately extended. Further, the excavating shaft 3 may be discontinuous.

合わせながらつなげて行く方法とがある。[0007] In order to construct a continuous underground wall using soil cement in this way, when a single-screw excavator is used as the auger 1, preceding excavation is performed at every other interval as shown in FIG. 4. After that, there is a method in which the preceding excavation is performed in a backward excavation, and a method in which the excavations are sequentially connected one by one as shown in FIG.
As shown in the figure above, the multi-screw excavator also performs pre-drilling at intervals of one drill (in the case of multi-screw, continuous holes of the same number of shafts), and There is a method of excavation at a later time, and a method of connecting one by one one by one while sequentially omitting them, although not shown.

This is a method of injecting around 2 × 60% and stirring to build a wall.

In order to build the wall of the unit, 0.5 × 2.0 × 1 × 0.5 = 6 m 3 , and about 6 m 3 of cement milk is required. Cement milk of 6 m 3 was injected at the same time as drilling auger 1, and drilling while injecting up to a predetermined depth, and,
Even when the auger 1 is pulled out, it is slightly injected, and the work is performed while turning (forward / reverse).

はできない。By the way, industrial waste remnants (mixture of soil cement and raw soil) are generated in excess of the amount of cement milk injected. Incidentally, in the conventional method shown in FIG. 3, such industrial waste residue is generated in all the steps (A) to (G). And enormous costs are required for disposal. On the other hand, an excessive amount of the excavated soil and the hardened material is agitated and mixed by the forward and reverse rotation of the auger, so that an extra load is imposed on the auger and efficient work cannot be desired.

材を注入せずに行うことを要旨とするものである。According to the present invention, in order to achieve the above object, an amount of excavated soil corresponding to an amount of a hardened material such as cement milk is previously discharged to the ground as advance excavation. The excavation is performed with the same core as the excavation, and a hardening material such as cement milk is injected at the same time as the latter excavation, and the excavated soil and hardened material in the latter excavation are mixed. In addition to this configuration, the preceding excavation shall be performed by a different excavation means than the subsequent excavation, and the subsequent excavation shall be performed by a soil cement pile builder, or the preceding excavation shall be the same as the subsequent excavation The gist of the invention is to perform the method without injecting a hardening material such as cement milk.

掘削土量が少ないことは大きなメリットとなる。According to the first aspect of the present invention, what is discharged to the ground in the preceding excavation is the general remaining soil as the original soil, which can be disposed without being turned into industrial waste. The mixing of the hardened material such as cement milk and the excavated soil is based on the fact that the hardened material is filled into the excavated portion, and the excavated soil is generated when the subsequent excavation is performed after the preceding excavation. Since the soil cement pile is constructed by using such a hardened material and excavated soil, it can be constructed without generating industrial waste residual soil. Further, the hardened material such as cement milk is not discarded together with the earth removal, so that it is economical without waste. In addition, in the subsequent excavation, the pile hole formed by the preceding excavation is further drilled with the same core, and the amount of excavated soil in the subsequent excavation can be reduced, so that the construction period can be shortened. In particular, in subsequent excavation, inject hardened material such as cement milk and mix this hardened material with excavated soil,
The small amount of excavated soil is a great advantage.
