It was just a matter of providing z. By the way, the excavation shaft (7
i) Excavated thfc excavated soil increases in volume due to the so-called soil bulging phenomenon during excavation 1'41J, and moreover, the consolidation liquid f61tq is discharged into the excavated hole (2) and kneaded. Therefore, the volume of the consolidation liquid (6) is also added, and as a result, the cross-conducting soil (8) is discharged to the ground as shown in FIG. This mixed soil (8) discharged onto the ground must be dumped somewhere else, which requires a large amount of dumping cost and labor. Since it contains a solidifying liquid (6) such as menthol, it will cause pollution if it is dumped, and various problems will also occur when it is dumped. Furthermore, mixed track soil and sand are thrown (
8) It is a waste to dump confectionery because it contains a caking liquid (6) such as cement milk, and there is a problem that the caking liquid cannot be used effectively in the appropriate amount. The present invention was invented in view of the above points, and its purpose is to directly compare the wall of the excavated hole following the formation of the excavated hole by excavating means such as a pit or excavating blade. It can also be safely formed with a large cross-sectional area, and the excavated soil and consolidation liquid can be excavated without being discharged to the ground, or even if excavated soil and consolidation fluid are not discharged to the ground as in the past. Can be completely kneaded in the holes,
'TFC consolidation liquid can be used effectively, and when the drilling axis is rotated km to excavate a hole and then consolidate the area around the hole, is there a consolidation 11s phase? To provide an entire excavating and kneading machine that can consolidate the surrounding area without rotating, so that consolidation can be done more quickly and effectively than when consolidation is done only by lowering due to its own weight.

In addition to this, a consolidation post (+
When 01 descends without rotating, a dumpling-shaped excavated hole (21 wall or Fig. 2, %: 3, Fig. 4) is created.
Consolidation n increases in the direction indicated by the arrow in the figure. Drill hole here (2)
Since the earth and sand on the wall of the wall is not removed at all and becomes compacted,
A space is created around the drilled hole (2), and the space is combined with the drilled hole (21) to form a hole (3) with a larger cross-sectional area than the drilled hole (21).
6) is the surrounding ground with a degree of consolidation. In this way, an excavated hole (2) is formed using the bales. When the hole 121 is formed, excavated earth and sand such as sediment discharged from the discharge hole are formed.
! 11 Pongee liquid (6) is designed so that almost all of it remains in the hole (31) without being discharged to the ground (in other words, excess mixed earth and sand is not discharged to the ground) or as in the conventional method. Excavate earth and sand to the ground in a large width (not discharged to the ground), excavate earth and sand by stirring the earth (15) in this hole 131 and use #+6) for consolidation. Knead and knead the earth and sand (8) to form a column (or wall of Elemesito)
It forms. Pull out the excavation shaft f71 Vi and use the same method again to install another column (or one wall)? It is possible to form an entire underground wall by forming columns (or walls of one element) in succession. In the above example, r/

る。In the present invention, as described in 1, the excavation means is provided at the lower end of the excavation shaft, and the same curved wall t of the excavation hole excavated by the excavation means is provided in the portion above the excavation means of the IklI-1j axis. [i
: From the rotational locus drawn by the excavation means for compaction, the maximum external part of the consolidation cap is solidified, and a spout for spouting the consolidation liquid is provided at the 4-way cutting means or the excavation. Excavated earth and sand and consolidation liquid on the shaft? The stirring part that mixes and stirs is coated with a gold film, so it can be used to form a hole by excavation means and the consolidation part! ;) The wall of the drilled hole at J?

A hole with a cross section 40 larger than the drilled hole? Can form and drill holes′
fCreated when descending from excavation fc"soil fl"t, [excavated soil and consolidation liquid? It was possible to provide an excavated and kneaded sheet metal that can be completely kneaded in the hole, and there is no dirt to be discharged to the ground, or even if it is discharged, it is not discharged in large quantities as in #Sakae. Therefore, if the pressing crosstalk machine of the present invention is used, the crosstalk earth and sand can be discharged to the ground. It is not necessary to dump to another site Ffr, there is no need for extra dumping work, there is no need to dump at a cost town or n1 for consolidation, so there is no pollution, and # for consolidation is only necessary. Since it can be used for solidification purposes, it can be used for consolidation purposes, and in this respect as well, it can be considered a cost-effective item. Furthermore, even if it is for the main light, the consolidation member is installed on the same side as the field F41J a K, so is it suitable for the excavation axis? When rotating and milling the excavated hole, the consolidation member not only descends and consolidates due to the weight of the milling and kneading machine, but also rotates while descending, then descends and consolidates, thereby easily and quickly cleaning the surrounding ground. , it is something that can be done secretly.
