As other technical documents, there are a rotary cutter type excavator of Japanese Patent Publication No. 49-5402 and a vertical hole excavator of Japanese Patent Publication No. 56-46015, the gist of which is a rotary cutter provided at the lower end of the main body frame. Excavating a rectangular ditch, excavating sediment,
It is a mechanism that sucks and removes muddy water to the ground via an earth discharge pipe.
In the earth retaining method by the above technology, other land (structure)
About 40 to 60 mm of the land from the boundary with will be unused. Therefore, in a building with a long boundary, for example, a construction site having a depth, this leads to a reduction in floor area. In particular, in a structure with a large number of floors, such as a middle- and high-rise building, the unused part of the floor area naturally becomes a problem.

On the other hand, as a prior art, there is an excavator of Japanese Utility Model Laid-Open No. 62-72359, which discloses a structure in which a continuous excavator is mounted on a tip of an arm of a heavy machine via a bracket. However, in this invention, since the bracket is located at the center of the continuous excavator, even if the continuous excavator swings around the bracket as a fulcrum, the swing area is extremely small and it is impossible to excavate deep into the ground. In addition, it is difficult to dig far away from heavy equipment, and because it is not a cantilever type and both sides are supported by brackets, naturally no drill hole is formed at the boundary. .

First, the heavy equipment 1 is moved, and the bucket device 20 hung on the boom 2 of the heavy equipment 1 via the support head 4 and the like is placed at a slight distance from the boundary line 29 or the building (building), so-called soil. Move along the line where the retaining wall is going to be constructed, install the bucket device 20 at the soil retaining start end predetermined position, and
Install 24 on the line at the starting point of the earth retaining. Then, when the main body drive device (not shown) of the heavy equipment 1 is operated, pressure oil is supplied from the main body drive device, the drive device 17 provided in the supporting sub head 4 is operated, and the bucket device 20 One of the buckets 24 makes a circular movement in the clockwise direction (arrow in FIG. 5), and the earth and sand are excavated by a plurality of buckets 24 that make a circular movement at the lower end. It is conveyed by these buckets 24 that make a circular transition upward and is discharged from the upper end side. After the excavation of a predetermined underground portion in this way, the boom 2 of the heavy equipment 1 swings downward (toward the ground) by the action of the cylinder 3, and the supporting head 4 and the supporting sub head 6 move. Both move downward. As a result, when the bucket device 20 further penetrates into the ground, at the same time, the bucket 24 at the lower end thereof excavates the earth and sand, and thereafter excavation and earth removal are performed in the same manner as described above. After that, as the excavation progresses, the boom 2 of the heavy equipment 1 sways downwards by the action of the cylinder 3, and the bucket device 20
The plurality of buckets 24 located at the lower end of the bucket 24 are always set to have a positional relationship so that the earth and sand can be surely excavated. The swing of the boom 2 of the heavy equipment 1 is controlled so as to enter into.

If the vertical hole is excavated by such operations and procedures,
This time, with the bucket device 20 still inserted in the so-called underground, the bucket 24 is moved around, the excavation and earth removal are repeated by the bucket 24 on the forward side, and the earth retaining on the forward side is made through the forward transition of the heavy machine 1. It moves forward toward the ground on the side (see the arrow on the forward side in FIG. 5), and excavates the same type of vertical hole that is continuous with the already excavated vertical hole. Incidentally, along with this excavation, a hardening material A such as water and cement is pressure-fed into the pit through the chute 30, and the hardening material A is filled into the pit to form a wall piece base material. . In this case, in order to reliably feed the hardened material A into the vertical hole and prevent the hardened material A from flowing into the vertical hole during excavation, the bucket device 20 is provided with a backward side (opposite to the forward direction). Shield plate 31
Is installed.

By repeating the above-mentioned operations, a continuous wall is formed on the earth retaining line through excavation by the bucket device 20, soil discharge, pumping of the hardened material A, and forward movement of the heavy machine 1.
In this process, when the hardened material A pumped and filled in the continuous vertical hole is still in the state of being raw dry, the reinforcing material 32 of steel such as H steel 32
When the end of the continuous soil retaining wall of one section is reached, the bucket device 20 is pulled up from the vertical hole and withdrawn, and then the last feeding of the hardened material A and the reinforcing material 32 are performed. When the above is inserted, a continuous earth retaining wall of a substantially linear shape is formed here.

After the continuous earth retaining wall of one section is constructed by the above-mentioned operation and procedure, the heavy equipment 1 is moved, and the bucket device 20 is installed at a predetermined position of the starting end of the next continuous earth retaining wall.
Install 24 on the line at the starting point of the earth retaining. After that, by performing the same operation as the construction of the continuous earth retaining wall of the above-mentioned one section, the next soil retaining wall of the next section is created in the same manner as described above, and further the continuous earth retaining wall of the above-mentioned one section is formed. The next section of continuous earth retaining wall, which is continuous with the wall or continuous with a slight interval, will be constructed.
