Description of the Related Art Conventionally, when a cylindrical starting or reaching shaft is installed in a propulsion method in which a propulsion pipe such as a fume pipe is buried in the ground, as described in Japanese Patent Publication No. 5-83717, for example. A frame 33 (corresponding to a base in the present invention) is supported by left and right outriggers 41 (numbers in the same publication, hereinafter the same) and a tracked vehicle 32 away from the ground surface. An annular clamp 27 (also equivalent to a gripping member) for gripping the outer periphery of the shaft unit 8 (also equivalent to a shaft casing) is arranged, and the frame 33 and the annular clamp 27 are connected to the frame 3.
3 are connected via a pair of revolving hydraulic cylinders 28 (also corresponding to hydraulic cylinders for swinging) attached to the left and right of the lower surface of the lower surface 3. A shaft rotating and pressing device 1 (in the present invention, referred to as a swinging press-fitting device for a shaft shaft) in which a clamp 27 is connected via a pressing hydraulic cylinder 29 (also equivalent to a press-fit hydraulic cylinder) is used. .

る。[0003] In the above shaft rotating and pressing device, the outer periphery of the shaft unit is gripped by an annular clamp, the ground below the shaft unit is excavated by an excavating device provided in the tracked vehicle, and a hydraulic cylinder for repetitive rotation is used. The vertical shaft unit is pushed down into the ground via the annular clamp by the pressing hydraulic cylinder 29 while repeatedly rotating the shaft unit alternately in different directions via the annular clamp, and the reaction force to the downward pressure is reduced. The supporting counterweights are installed on the left and right sides of the front part (outrigger side) of the frame, and the weight of the tracked vehicle that supports the rear part of the frame also plays a role as the counterweight.

The crawler-type vehicle is positioned as a dedicated machine for forming a shaft, which is virtually integrated with a shaft rotating and pressing device, and cannot exhibit its original versatility and mobility. Since the endless track type vehicle requires an attachment for connecting the shaft rotating and pressing device, there is also an inconvenience that a general endless track type power shovel or the like cannot be used as it is.

Since the frame is supported horizontally away from the ground surface, the overall structure is complicated, such as requiring an outrigger with a built-in cylinder.In addition, an annular clamp and a hydraulic cylinder for repeated rotation are provided at the bottom of the frame. There is a problem that maintenance such as inspection and maintenance is difficult to perform due to the structure for installation. Also, since the components such as the frame and the outrigger are bulky, a large vehicle is required for transportation, and a large installation area is required during operation. However, along with the increase in the sewerage penetration rate, the need to form vertical shafts along narrow roads where large vehicles cannot be installed or where the above equipment cannot be installed has been increasing. It has been demanded.

First, the swing press-fitting device 1 is set at a predetermined position, and the counterweight 10 is mounted. Next, the press-fitting hydraulic cylinder 5 is operated to lift the gripping member 3 upward, and the first casing 31 having a cutting edge formed at the lower end is inserted inside the arc-shaped pieces 12 to 14, and the gripping cylinder 15 Is operated to reduce the diameter, and the outer periphery of the first casing 31 is gripped. Subsequently, the press-fitting hydraulic cylinder 5 is operated to push the gripping member 3 downward, and at the same time, the swinging hydraulic cylinders 8 are alternately expanded and contracted to rotate the gripping member 3. Thereby, the first casing 3 held by the holding member 3
1 is pressed into the ground while rotating and swinging. At this time, the reaction force received by the swing press-fitting device 1 is supported by the counterweight 10. The excavator 30 excavates and removes the ground in the first casing 31 in parallel or alternately with the press-fitting operation by the swing press-fitting device 1.

The next cylindrical casing (middle casing 32) is connected to the upper end of the first casing 31 and is gripped by the gripping device 3. The rocking press-fitting device 1 presses the excavator 30 while rotating and rocking them together. In order to excavate and remove the soil inside the casing as needed, the next middle casing 33 is added and press-fitted. 31
To reach the desired depth. In this example, a plurality of casings are added and press-fitted, but one long casing may be used.

The size can be greatly reduced as compared with the conventional example (in the above-described conventional example, the width of the device is about twice the diameter of the casing, but in the present invention example, it is only about 1.2 times). Therefore, it can be transported and installed even in a narrow place where the conventional rotary pressing device cannot be used. Then, as shown in FIG. 4, the locking portion 18 of the counterweight 10 is provided on one long side (in plan view) of the counterweight 10, and this is fitted into the locking piece 9 of the swing press-fitting device 1, whereby the device The front and rear width can be made smaller.

造が単純化され、メンテナンスも容易となった。According to the above-mentioned rocking press-fitting device, the track is restored to its original versatility and mobility by installing the base on the ground surface and eliminating the connection with the tracked vehicle. Since a special attachment is not required, there is an advantage that a general-purpose track type power shovel or the like can be used as it is. And, in the above-mentioned rocking press-fitting device, by installing the base on the ground surface, it is not necessary to provide a large frame or outrigger as in the conventional device, and the stability when installed is increased, and the device can be further downsized. It became. By removing the detachable counterweight from the base, the size can be further reduced during transport. In addition, since the gripping device, the hydraulic cylinder for press-fitting, and the like are all set on the base, the structure of the device is simplified, and maintenance is facilitated.
