術は知られている。2. Description of the Related Art For example, as shown in FIG. 9, a rotating / propulsion device 17 in which a casing pipe 1 is connected to a power supply device 16.
The bucket device 10 is provided with a bucket device 10 for fixing the bucket device 10 or the screw conveyor device for excavating and taking in the inside thereof to the casing pipe.
Alternatively, a technique in which the conveyor device 15 and the conveyor device 15 are mutually fixed is known.

がある。However, in the above technique, since the casing inner surface and the bucket device are fixed by the gripper device, the drag bit at the tip of the casing and the cutter of the bucket device excavate at the same time when the casing is propelled. Therefore, there is a problem that the excavation force becomes large.

In the digging device that takes in the water, between the bucket device that digs the inside and the gripper device that fixes the bucket device to the casing, an expansion / contraction means that can transmit a rotational force and can expand / contract the gap between the bucket device and the gripper device. A control device for controlling the expansion and contraction means is provided.

装置においてより深く、大きな径の掘削が可能となる。In the bucket self-elevating excavator constructed as described above, the casing propulsion and the bucket propulsion can be arbitrarily selected, so that the casing propulsion and the internal excavation intake can be performed separately. It enables deeper and larger diameter excavation with the same rotary and propulsion device.

付けられている。In FIG. 1, a casing 1 is attached to a casing rotation / propulsion device (not shown), and its tip portion 1
A fast tube 2 is fixed to a, and a drag bit 2a is attached to the tip of the first tube 2 in a sawtooth shape.

5とが懸吊されている。Further, inside the casing 1, a bucket 10 for excavating the inside of the casing 1 through a wire 4 on a hook 3 of a Clen not shown, a gripper device 6 and a space between the bucket 10 and the gripper device 6. The kelly bar 9 which is an expansion / contraction means for expanding / contracting the space and its control device 5 are suspended.

る。ここで、符号7はアキュムレータを示す。The gripper device 6 is provided with a plurality of grippers 6a in upper and lower two stages, and a gripper jack 6b.
Then, the gripper device 6 is fixed to the center of the casing 1. Here, reference numeral 7 indicates an accumulator.

れている。Also, referring to FIGS. 2 and 3, inside the gripper device 6, a kerry bar 9 can transmit a rotational force to the bucket device 10 via a hydraulic jack 8 and a kelly bar guide 9a. And it is attached so that it can expand and contract.

きる。Therefore, referring to FIG. 4, in response to a signal from the control device 5, the gripper device 6 is fixed in the casing 1 by the gripper 6a, and pressure oil is sent to the hydraulic cylinder 8 via the accumulator 7, so that the kelly bar 9 is removed. The rotating force can be transmitted in a state where the bucket 10 is pushed down with respect to the casing 1 and the relative positions of the casing 1 and the bucket 10 are changed.
【0014】以下、図5〜図8を参照して、掘削方法に
付いて説明する。The excavation method will be described below with reference to FIGS.
【0015】ケーシング1を回転させ、推進することで
ケーシング1の内外に溝を掘削する(図5)。The casing 1 is rotated and propelled to excavate a groove inside and outside the casing 1 (FIG. 5).
【0016】この時ケーシング1内の土砂、岩等はケー
シングと一緒に回転するのでバケット10を押入れても
バケットに土砂を取込めない(図6)。At this time, since the earth and sand, rocks, etc. in the casing 1 rotate together with the casing, even if the bucket 10 is pushed in, the earth and sand cannot be taken into the bucket (FIG. 6).
【0017】バケットを土砂面に押付けた状態で、土砂
がとも回りしない高さまでケーシング1だけ引き上げる
(図7)。With the bucket pressed against the earth and sand surface, only the casing 1 is pulled up to a height at which the earth and sand do not rotate (FIG. 7).
【0018】ケーシング1にグリッパ6aでバッケット
を固定してケーシングを回転推進すればケーシングの先
端部は掘削せずにバケット10に土砂を取込めるので、
引上げればよい(図8)。ケーシングとバケットとは同
時掘削がないので、掘削力は小である。If the bucket 1 is fixed to the casing 1 by the gripper 6a and the casing is rotated and propelled, the tip of the casing can be loaded into the bucket 10 without excavating,
Just pull it up (Fig. 8). Since the casing and the bucket are not simultaneously excavated, the excavation force is small.

ができる。Since the present invention is configured as described above, the casing and the bucket can be independently propelled, so that the characteristics of the ground and the power of the rotation / propulsion device of the casing installed on the ground can be used. A plurality of excavation methods such as casing leading and bucket leading can be adopted, and efficient construction can be performed.
