9 ... is standing, but this protection 29
Are also linked to each other, and some of them are also expandable and contractible in the horizontal direction. As the work stage 21 is deformed, the work stage 21 is always surrounded.

Work stage 21 having such a configuration
The operation of will be described. First, as shown in FIG.
When the piles P are driven along a straight line, in the work stage 21, the fixed shafts 23 a and 23 a of the base stages 23 and 23 of the work stage 21 and the connection shafts 24 a of the first connection stages 24 and 24 are connected. 24a, the connecting shafts 25a and 25a of the second connecting stages 25 and 25 are linearly arranged, and the connecting shafts 25a and 25a of the two second connecting stages 25 and 25 and the connecting shaft 26a of the middle stage 26.
And a right angle.

In this state, the tip portion of the pile press-in / pull-out machine 31 and the first connection stages 24, 2
The fourth connection stage 25 and the second connection stage 25 are in proximity to each other. That is, in this state, when the swivel portion 35 of the pile press-in / pull-out machine 31 is to be largely turned right and left, the tip of the pile press-in / pull-out / pull-out machine 31 is moved to the work stage 21.
You can't make a big turn.

It is possible to continuously press the piles P... While turning the swivel section 35 so that the tip of the pile press-in / pull-out machine 31 does not hit the work stage 21. Therefore, in this state, the continuous direction in which the piles P are continuously driven can only be a straight line or a slightly curved curve, and the continuous direction of the piles P can be bent at a right angle or greatly curved. Can not.

When the continuous direction in which the piles P are continuously driven is bent to the right in the traveling direction at a right angle on the way, each connecting portion of the work stage 21 is operated as shown in FIG. The middle stage 26 of the work stage 21 is largely moved to the rear left in the same direction.
In this case, the pile press-in and pull-out machine 31 and the left edge of the tip portion,
First connection stage 24 and second connection stage 25 on the left side
As shown in FIG. 16, even if the turning part 35 of the pile press-in / pull-out machine 31 is largely turned to the left as shown in FIG.
Never hit. In addition, when turning the turning part 35 to the right, the middle stage 26 can be moved to the rear right side to cope with the case of turning to the left.

As shown in FIG. 16, while the middle stage 26 is largely moved to the rear left with facing the same direction, the turning part 35 of the pile press-in / pull-out machine 31 is turned to the left largely. In the state, since the distance between the tip of the pile press-in / pull-out machine 31 and the work stage 21 does not greatly separate, the workability on the work stage 21 does not deteriorate. In addition, from the beginning, the scaffold was inserted into the pile press-in / pull-out machine 31.
If it is fixedly mounted in a state largely separated from the left and right of the tip of the pile, the tip of the pile press-in / pull-out machine 31 does not hit the scaffold even if the turning part 35 of the pile press-in / pull-out machine 31 is largely swung, and the pile press-in / pull out It is possible to turn the turning portion 35 of the machine 31 greatly, but in this case, the pile press-in and pull-out machine 31 is used.
Of the pile press-in / pull-out machine 3
The distal end of the first scaffold is largely separated from the scaffold, and workability on the scaffold deteriorates.

When the piles P are continuously pressed into a circular shape with a relatively small radius, or when the piles P are continuously press-fitted with a relatively large curvature, the piles P are connected at right angles to each other. 15, the turning part 35 of the pile press-in / pull-out machine 31 does not need to be largely turned. However, in the state shown in FIG. 15, the tip end of the pile press-in / pull-out / pull-out machine 31 hits the work stage 21. In this case, as shown in FIG. 17, each connecting portion of the work stage 21 is operated, and the middle stage 26 of the work stage 21 is slightly moved right rearward (or left rearward) in the same direction. State.

In this state, since the pile press-in / pull-out machine 31 and the right edge of the tip are slightly separated from the right first connection stage 24 and the second connection stage 25, as shown in FIG. Even if the turning part 35 of the pile press-in / pull-out machine 31 is slightly turned to the right, the tip of the pile press-in / pull-out machine 31 does not hit the work stage 21 and the pile press-in / pull-out machine 31
And the work stage 21 are not separated from each other.

That is, the work stage 21 of the second example
Since the rotation angle of each stage of the work stage 21 can be adjusted stepwise as described above, the work stage 2
1 can be modified. Therefore, the pile press-in and pull-out machine 31
When the turning portion 35 is turned at an arbitrary angle, the work stage 21 and the tip of the pile press-in / pull-out machine 31 are prevented from coming into contact with each other. It is possible to prevent the workability on the work stage 21 from being deteriorated due to being too far away.

Further, by deforming the work stage 21 as described above, even when the work stage 21 is completely surrounded by the periphery of the front part of the pile press-in / pull-out machine 31, the turning part 35 can be turned. Revolving part 35 of press-in / draw-out machine 31
It is not necessary to prepare a plurality of scaffolds having different shapes in the case of turning and in the case of not turning, and it is not necessary to replace the scaffolds in the case of turning the turning part 35 and in the case of not turning, thereby reducing the cost of the scaffold, It is possible to save labor for changing scaffolds.

The present invention is not limited to the work stage 21 of the second example, and the design can be changed.
For example, each of the stages constituting the work stage 21 is detachably attached to improve the storability, the number of the stages constituting the work stage 21 and the number of links are increased, and each of the fixed shaft 23a and each of the connection shafts 24a, 25a, 26a may have a curved shape.

In the second example, the rotation angles of the stages can be adjusted stepwise. However, the rotation angles may be continuously adjusted steplessly.
The stages may be rotatably driven by hydraulic cylinders or the like. When the work stage 1 is provided not on the pile press-in / pull-out machine 31 but on the above-described pile-based moving scaffolding apparatus, the pile press-in / pull-out 31 is arranged in front of the pile-based moving scaffolding apparatus, A similar effect can be obtained by providing the work stage 21 so as to go around the front of the pile press-in / pull-out machine 31 from both sides of the upward moving scaffolding device.
