Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing an obstacle buried or buried underground.

[0002]

2. Description of the Related Art In order to remove obstacles such as pine piles, piles and concrete buried and buried in the ground, as shown in FIG. and a rotary drive (96), the obstacle removal rig (90) which is rotatably deploy cylindrical casing (94) that have been known.
Cutting teeth (97) are formed at the lower end of the casing (94) .The casing (94) is pushed into the ground while rotating forward and backward to crush and cut underground obstacles.
Obstruction is removed by pulling out 4). In addition, as shown in FIG.
The base is installed, and the casing (94) is attached to the lower rotary drive (96).
The upper rotary drive (96) has a screw
(98), and screw (98) to casing (94).
There is also an obstacle removal and excavation device (92) fitted inside the vehicle. In this device, the casing (94) is pushed into the ground while rotating forward and reverse, and the screw (98) is rotated inside the casing (94).
Is rotated while moving up and down to crush the obstacles taken in the casing (94), thereby removing the obstacles.

[0003]

In the former obstacle removal and excavation device (90), when crushing and cutting pine cones, boulders, reinforcing steel in concrete, etc., these move together with the rotation of the casing to crush and cut. There is a possibility that it will not be performed or will remain in the hole after the casing is pulled out.

In the latter obstacle removing and excavating apparatus (92), when reinforced concrete is crushed, the reinforcing steel may peel off from the concrete and become entangled with the casing or the screw, or a piece of wood or wire may be entangled with the screw. There is a problem that takes time.

It is an object of the present invention to efficiently crush obstacles,
It is an object of the present invention to provide an obstacle removing and excavating method which can be cut.

[0006]

In order to solve the above-mentioned problems, an obstacle removing and excavating method according to the present invention is provided so as to be vertically movable independently along a leader (70) and to be independently driven. first and second rotary drive apparatus (20) (30), distribution to the lower
A cylindrical first casing (22), which is connected to a first rotary drive device (20) placed and has a cutting tooth (24) provided at a lower end thereof ;
The cylindrical second casing (30) is connected to the second rotary drive device (30) arranged on the side , is fitted in the first casing (22) , and is provided with cutting teeth (34) at the lower end. 32) with an obstacle removal drilling method using an obstacle removal drilling device equipped with
The first casing (22) and the second casing (32) are
While rotating in the opposite or opposite direction, or the casing
While only one is rotated, the two casings (22) (3
2) is moved up and down relatively, and the lower end of the second casing (32) is
Press-fit while extruding from the lower end of the first casing (22) and excavate
It cuts and crushes obstacles.

[0007]

[Operation and Effect] While driving the first rotary drive device (20) and the second rotary drive device (30), the first casing (22) and the second casing (32) are rotated in the same direction or in the opposite direction. Or, while rotating only one of the casings, move both rotary drive units (20) and (30) downward to
(32) is pressed into the ground. When the casings (22) and (32) are pressed into the ground, obstacles are crushed and cut by the combined force of the two casings (22) and (32). In particular, when the first casing (22) and the second casing (32) are pressed into the ground while rotating in opposite directions, the obstacle is crushed by the shearing action of both cutting teeth (24) and (34), Can be cut. Therefore, it is possible to crush, cut, and remove easily movable boulders and reinforcing steel in concrete. The first rotary drive device (20) second rotary drive device (30) are relatively moved vertically, the second cable
The lower end of the single (32) protrudes from the lower end of the first casing (22).
When the press-fitting is performed, the obstacle can be crushed and cut more effectively.

[0008]

FIG. 1 is a side view showing a state in which an obstacle removing and digging apparatus (10) of the present invention is mounted on a construction machine (72), and FIG. 2 is an obstacle removing and digging apparatus (10). FIG. 3 is a perspective view showing a cross section of a part of FIG. Construction machinery (72) is a self-propelled vehicle (74)
A reader (70) is erected in front of the device. Reader (70)
Has two upper and lower rotary drive units (the first rotary drive unit (20)
And the second rotation drive device (30) are independently provided so as to be able to move up and down. The lifting mechanism of the rotary drive devices (20) (30) can be exemplified by a rack / pinion type, a chain type, a wire type, and the like.

The rotary drive units (20) and (30) are connected to cylindrical casings (22) and (32), respectively. A first casing (22) is rotatably connected to the lower first rotation drive device (20) by flange connection. In addition, the rotation drive device (20)
The casing (22) is not limited to the flange connection. A drive shaft (36) is rotatably connected to the upper second rotary drive device (30), and a second casing (32) is coaxially connected to a lower end of the drive shaft (36). Have been.

The cutting teeth (2) are formed on the lower peripheral edge of the first casing (22).
4) is provided. The second casing (32) is disposed concentrically inside the first casing (22) with a predetermined gap, and similarly to the first casing (22), the cutting teeth (3
4) is provided. The upper end of the second casing (32) is closed by a lid member (38), and a drive shaft (36) is connected to the center of the lid member (38).

With respect to the obstacle removing and excavating apparatus (10) having the above-described structure, the rotary driving apparatuses (20) and (30) are lowered while rotating in the same direction or in the opposite direction, and are pressed into the ground to obtain an obstacle. Is crushed and cut. At this time, FIG.
As shown in (c), the first casing (22) and the second casing (32) are moved up and down relatively, and are moved below the second casing (32).
When the press-fitting is performed with the end protruding and retracting from the lower end of the first casing (22) , more effective crushing and cutting of obstacles can be performed. Note that the rotation speeds of the first casing (22) and the second casing (32) may be set to be the same or may be rotated at different rotation speeds. Alternatively, only one casing may be rotated and the other may be stopped.

After the casings (22) and (32) are press-fitted to a predetermined depth, the two rotary drive units (20) and (30) are raised, and the casings (22) and (32) are pulled out from the ground, thereby crushing and crushing. The cut obstacle can be pulled out from the ground together with the casing.

[0013] The description of the above embodiments is for the purpose of illustrating the present invention and should not be construed as limiting the invention described in the claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.

For example, a screw can be further inserted inside the second casing. Put the screw,
By rotating inside the second casing, particles such as sandstone can be removed.
