The reel device 106 is configured such that forward and reverse rotation is possible under the control of a control device (not shown). If the reel of the reel unit is rotated forward, the drain material can be released from the reel.

The leader 102 is installed in a state in which the vertical angle adjustment is possible on the main body of the drain material placing apparatus, and the drain casing fixing holder 103 is movable up and down along the vertical direction of the leader.

The drain casing fixing holder is fixed to the pulley 144 winding the wire 133 is indirectly driven by the hydraulic cylinder 145, or configured to drive the hydraulic cylinder directly to the drain casing fixing holder without a wire. do.

The drain casing 104 is fixed to the drain casing fixing holder 103 in a detachable state.

The drain casing has a through hole 108 formed therein, and the temporary temporary fixing device 46 is installed in the lower body portion. In addition, a groove 54 is formed at the lower end of the drain casing for mounting the support 47 of the drain material temporary fixing device.

The drain material temporary fixing device 46 includes a rod-shaped support body 47 for supporting the drain material 105 lowered to the lower end portion through the through hole 108 of the drain casing, and the support from the lower end opening of the drain casing. An arm 48 is provided to be spaced apart by a predetermined distance (within 2 m: preferably 0.5 m to 0.1 m) toward the vertical downward, and drive means for advancing and retracting the arm.

The driving means is configured by installing the spring device 50 on both sides of the lower end of the drain caching as shown in FIG. The elastic force of the spring device is set to have about 7-8kg slightly smaller than the set tension of the reel device 106, the drain material 105 is attached to the ground by the elastic force of the spring device in the state that the tension of the reel device is working It is configured not to go down.

In addition, the support body 47 has a rod-shaped structure that crosses the lower end opening of the drain casing 104, and one end of the arm 48 is connected and fixed to both sides of the support body, respectively. The arm is installed in close contact with the body of the drain casing in parallel with the direction of the center axis of the drain casing, and the other end of the arm is connected to the driving means fixed to the body portion of the drain casing.

Example

This embodiment describes the case where the drive means of the arm 48 and the support body 47 are constituted by the spring device 50 as an example.

First, after the operator forcibly pushes the arm 48 and the support 47 of the drain material temporary fixing device 46 fixed to the lower end of the drain casing 104 as shown in FIG. 10A toward the lower end opening of the drain casing. After bending by bending U-shaped drain material 105 on the stiff band exited through the through hole 108 of the drain casing at the lower side of the support 47, the end end is overlapped by about 3 cm to 5 cm. It is inserted in the lower end opening of the casing and the reel device 106 is driven back so that the tension of the drain material 105 (10 kg or less) is maintained.

In the state where the tension of the drain material is maintained, the elastic force of the spring device 50 is set to 7-8 kg which is slightly smaller than the tension of the drain material, and thus the support 47 is maintained in close contact with the end of the drain casing.

When the end of the drain material is overlapped by about 3-5 cm, and the support 47 is wrapped in a U shape and inserted into the lower end opening (through hole) of the drain casing, the tension of the reel device of the drain material (9 to 10 kg) is sufficient. In this case, the drain material is smoothly released without being separated from the support, but when the tension of the reel device is released, the portion of the drain material wound around the U-shape and the support are opened by the elastic force of the spring device 50, and thus the lower opening of the drain casing (through hole). Escape from and easily escape from the support 47.

Therefore, unless the tension of the reel device 106 is released, the portion of the drain material wound in a U-shape and fitted into the through hole serves to prevent the support body 47 from being separated, and at the same time, the support body 47 is surrounded by the drain material. The portion shields the lower opening of the drain casing so that no soil is introduced into the through hole of the drain casing.

On the other hand, when the driving means is a hydraulic or pneumatic cylinder device 60, 70 as shown in Figs. 8 and 9 by using the control device (not shown) to drive the hydraulic or pneumatic cylinder device by the arm 48 and the support ( What is necessary is just to move 47) to the lower end opening part of the drain casing 104, and the structure which winds up the edge part of the drain material to the support body 47 in U shape, and inserts it into the through-hole of a drain casing is the same as that of FIG.

Next, as shown in FIG. 10B, the drain casing 104 is inserted to a predetermined depth in the ground. In the process of inserting the drain casing, the load applied in the vertical direction to the support 47 is absorbed by the close drain casing, but the load applied from the side is absorbed by the buffer member 80 (spring) to bend or deform the arm 48. It works to prevent it.

Subsequently, when the tension of the reel device 106 is released and the drain casing 104 is pulled out as shown in FIG. 10C, the drain material 105 is placed on the ground by the lower side of the support 47 of the drain material temporary fixing device 46. Pressed on the floor to remain fixed.

The height at which the drain casing 104 is drawn in the state where the drain material 105 is fixed to the bottom of the ground by the support 47 is determined by the length of the arm 48.

The length of the arm can be adjusted according to the condition of the soft ground is preferably set within 2m, preferably 0.2m ~ 0.7m.

When the drain casing 104 is pulled about 0.2 m to 0.7 m from the ground while the support 47 is pressing the end of the drain material 105 as shown in FIG. 10C, the earth's pupil is rapidly pushed out by the pressure. It is filled, and the earth-drain material end part is buried and fixed by this filled soil. When the hydraulic or pneumatic cylinder device 60, 70 is used as the driving means, the drain material 105 is driven by the support 47 while the hydraulic or pneumatic cylinder device is driven to draw the drain casing by a predetermined height. You can press it on the ground to keep it fixed.

When the drain casing 104 is further drawn in the state of FIG. 10C, as shown in FIG. 10D, the support 47 held against the end of the drain material 105 is released from the end of the drain material and begins to be drawn together with the drain casing. do. In the process of drawing the support, even if the support is caught in the soil or rock in the ground, the shock is not transmitted to the arm 48 as it is, but the shock absorbing member 80 is absorbed, thereby preventing the arm from bending or deforming. .

Subsequently, after the drain casing 104 and the drain material temporary fixing device 46 are drawn from the ground to the ground as in 10e, the operator cuts the proper position of the drain material 105 and then moves the drain casing. Repeat the process of 10a ~ 10e.

The drain material placing apparatus capable of embedding the drain material without the anchor plate of the present invention is not limited to the above-described illustrated structure, and various modifications are possible within the scope of the claims and objects of the present invention.
