On the other hand, in the embodiment shown in FIG.
) are all arranged to rotate in the same direction, and the winding directions of the screw portions (3) provided on adjacent vertical rotating shafts are arranged in opposite directions. However, the first
The construction is carried out using an excavator (8) as shown in the figure or an excavator as shown in Fig. 3, and the construction is carried out as follows. First, the rotary device ill is rotated to rotate several rotary vertical shafts (2), and the ground is excavated at the pit (6) at the tip of the rotary vertical shaft (2). In this case, excavation is performed while spouting a liquid such as cement milk or a mixture of cement milk and asphalt milk from the pit +6+. It is pulled out while moving up and down.By the way, in the present invention, during the above process, the excavation *(A) shown in Fig. 1 is performed.
Or, in any case of the excavator cage shown in Fig. 3, the mixture of excavated soil and liquid is removed by the screw part (3) installed on one of the adjacent rotating vertical shafts (2). is mixed and stirred.
However, the mixture of excavated soil and liquid is mixed and stirred by the screw part (3) installed on the other rotating vertical shaft and moved downward, causing the excavation to move upward. Excavation where the mixture of earth and sand and liquid moves downward The mixture of earth and sand and liquid will be stirred and mixed with each other, and uniform mixing and stirring will be achieved in the vertical direction. As described above, in the excavation line of the example shown in the figure, the inside of the excavation hole, which has a rectangular cross section, is converted into soil cement where excavated soil and liquid are mixed, or asphalt on soil, and the vertical axis of rotation (2j is removed). A column H of tweel cement with a rectangular cross section to a column 04 of medied asphald on soil are formed.The column Of formed as described above is
) may be inserted with a metal structure or a structure made of metal and cosicrete, if necessary. Alternatively, a retaining wall may be formed by sequentially forming other columnar bodies adjacent to the columnar body so that their ends overlap with each other. As the asphalt emulsion used in the present invention, an asphalt emulsion that is chemically and physically emulsified and melted as shown in Patent No. 250862 is used, and when asphalt emulsion is used, the water stopping effect is improved. can be done.

支障がないものである。In the present invention, as described above, nine holes are made in the ground using a plurality of rotating vertical shafts with a plurality of screws partially spaced apart in the vertical direction, and cement milk or cement milk and asphalt are poured into the holes in the excavated hole. A consolidation liquid such as a mixed liquid with a liquid is ejected, and a part of the screw installed on one of the adjacent rotating vertical shafts raises the excavated soil and the consolidation liquid upward, and the other A part of the screw installed on the rotating vertical shaft lowers the excavated soil and consolidation liquid while mixing and stirring to form a wall on the ground, so that the mixture of excavated soil and liquid that moves upward is forced downward. The mixture of the excavated earth and sand and the liquid that moves to the wall are stirred and mixed with each other, so that uniform mixing and stirring can be performed in the vertical direction, and a wall body with uniform strength can be formed in the vertical direction. In particular, even if the ground to be excavated has different layers connected in the vertical direction, such as a gravel layer or a clay layer, it is possible to form a wall that is evenly mixed on the top and bottom, but it is easy to create a wall that is evenly mixed on the bottom. The excavator provides an excavator that can excavate soil by using a simple mechanism such as changing the direction of rotation of multiple rotating vertical shafts or changing the winding direction of part of the screw. At the same time, the excavated earth and sand and liquid are moved upward using another part of the adjacent screw, and the excavated soil and liquid are moved downward to uniformly mix the excavated soil and liquid vertically. Furthermore, each rotating vertical shaft of the excavator of the present invention has a portion of a screw in the vertical direction, so each rotating vertical shaft has high rigidity, does not warp in an arch shape during excavation, and improves the stability of the ground. Even in the case of a hard gravel layer, there is no problem in excavation.
