  Next, the soil removal processing apparatus 30 according to the present invention will be described.

  For example, as shown in FIGS. 1A, 2, and 3, the soil removal processing device 30 is configured to remove the soil excavated by the excavation device 100 (auger device 20) and excavation device 100 (pile press-fitting device 10). 1st soil removal conveyance part 31 conveyed in the direction which cross | intersects the moving direction of this, and the back of the movement direction of the excavation apparatus 100 (pile press-fit apparatus 10) the soil discharged by the 1st soil removal conveyance part 31 The second soil removal transport unit 32 transported to the ground, and the soil removal input unit for placing the soil transported by the second soil discharge transport unit 32 into the excavation hole excavated by the excavator 100 (auger device 20) 33, and a frame 34 or the like that supports the first soil removal transport unit 31, the second soil discharge transport unit 32, and the soil discharge input unit 33 in a predetermined arrangement. The first soil removal transport unit 31 and the second soil removal transport unit 32 transport the soil excavated by the excavation device 100 (auger device 20) in a direction away from the excavation device (auger device 20). To do.

The frame 34 is attached and fixed to an attachment fixing portion 12a provided on the saddle 12 of the pile press-fitting device 10. The frame 34 has rigidity capable of supporting the first soil discharge transport unit 31, the second soil discharge transport unit 32, and the soil discharge input unit 33.
Note that the attachment fixing portion 12a may be provided in the saddle 12 for attaching the soil removal processing device 30 to the pile press-fitting device 10, or may be a recess, flange or bolt, such as a groove or bolt hole provided in advance in the saddle 12. A convex part such as a head may be used.

The first soil removal transport unit 31 includes, for example, a table 31a on which the soil excavated by the excavator 100 (auger device 20) is placed, a scraper 31b that advances and retreats on the plate surface of the table 31a, and a scraper. The hydraulic cylinder 31c which drives 31b forward and backward is provided.
The table 31 a is held by the frame 34 so as to be positioned below the shooter 25 (the bellows hose 26) of the auger device 20. A scraper 31b is disposed at a standby position on the left end side of the table 31a (left side with respect to the moving direction of the pile press-in device 10), and a cylinder tube of a hydraulic cylinder 31c having a piston rod connected to the scraper 31b is fixed to the table 31a.

That is, every time the pile press-fitting device 10 moves forward on the steel pipe pile row, it is not necessary to adjust the orientation of the shooter (33).

Further, the soil removal processing apparatus 30 includes a control unit (not shown) that operates the belt conveyor (32) for a predetermined time in response to the scraper 31b of the first soil removal transport unit 31 having advanced and retracted once a predetermined number of times. I have.
By controlling the belt conveyor (32) to operate for a predetermined time in response to the advance / retreat of the scraper 31b once, the soil is discharged from the first soil discharge transport unit 31 to the second soil discharge transport unit 32. Since the belt conveyor (32) can be operated at the transported timing, for example, when there is no soil on the belt conveyor (32), the belt conveyor (32) is prevented from rotating unnecessarily. it can.
As will be described later, the ribbon screw (32) operates for a predetermined time in response to the scraper 31b having advanced and retracted once even when the second soil removal transport unit 32 is configured with a ribbon screw. By controlling in this way, unnecessary operation of the ribbon screw (32) can be suppressed. Further, the predetermined number of times is set to 2 or 3 times, and the control unit (not shown) operates the belt conveyor (32) for a predetermined time in response to the advancement / retraction of the scraper 31b twice (or three times). It may be.

In the soil removal processing device 30 having such a configuration, the soil excavated by the excavation device 100 (auger device 20) is temporarily placed on the table 31a of the first soil removal transport unit 31, and the soil removal is performed. The excavator 100 (the auger device 20) can be transported from the first soil discharge transport unit 31 to the second soil discharge transport unit 32 and transported from the second soil discharge transport unit 32 to the soil discharge input unit 33. ) Is excavated into the excavation hole (herein, in the steel pipe pile P), and the excavation process can be performed for backfilling.
In particular, since the soil removal processing device 30 is attached to the excavation device 100 and used, the soil removal processing is performed even after the excavation device 100 (pile press-fitting device 10) moves on the steel pipe pile row. Can be continued.
That is, since it is not necessary to attach / remove the soil removal processing device 30 each time the excavation device 100 is moved, the burden on the operator can be reduced and the soil removal processing can be saved.

Moreover, in the said Embodiment 1, the soil removal processing apparatus 30 is arrange | positioned so that the 2nd soil removal conveyance part 32 of the soil removal processing apparatus 30 may be arrange | positioned on the right side of the moving direction of the excavation apparatus 100 (pile press-fit apparatus 10).

With the soil disposal device 70 having such a configuration, the soil excavated by the excavator 200 (auger device 60) is transferred to the second soil transport unit 32 by the shooter (first soil transport unit 71). The soil can be transported and transported from the second soil removal transport unit 32 to the soil discharge input unit 33, and the soil discharged into the excavation hole excavated by the excavator 200 (auger device 60) is backfilled. Processing can be performed.
In particular, since the soil removal processing device 70 is attached to the excavation device 200 and used, the soil removal processing is performed even after the excavation device 200 (pile press-fitting device 50) moves on the pile row. It can be done continuously.
That is, since it is not necessary to attach / remove the soil removal processing device 70 every time the excavation device 200 is moved, the burden on the operator can be reduced and the soil removal processing can be saved.

Moreover, in the said Embodiment 2, the earth removal processing apparatus 70 is arrange | positioned so that the 2nd earth removal conveyance part 72 of the earth removal processing apparatus 70 may be arrange | positioned on the right side of the moving direction of the excavation apparatus 200 (pile press-fit apparatus 50). Although attached, it is not limited to this.
For example, the first soil removal transport unit 72 and the soil removal input unit 73 are attached so as to be arranged on the left side in the moving direction of the excavating device 200 (pile press-fitting device 50) and attached to the casing 61. 71 (shooter) may be directed to the left side in the moving direction of the excavator 200 (pile press-fitting device 50).
For example, when a “U-shaped sheet pile” is used as the pile P, the excavation holes excavated by the excavation apparatus 200 (auger apparatus 60) are alternately formed on the left and right sides of the pile row. In such a case, according to the position of the excavation hole, the arrangement of the second soil discharge transport unit 72 (the soil discharge input unit 73) may be changed so as to be switched left and right. Moreover, you may attach the 2nd soil removal conveyance part 72 and the soil removal injection | throwing-in part 73 beforehand to the both right and left sides of the moving direction of the excavation apparatus 200 (pile press-fit apparatus 50). If the 2nd soil removal conveyance part 72 and the soil removal injection | throwing-in part 73 are arrange | positioned at the both sides of a pile row | line | column, it will become unnecessary to perform replacement according to the position of a digging hole.

Moreover, although the 2nd earth removal conveyance part 72 in Embodiment 2 was provided with the belt conveyor, this invention is not limited to this, The 2nd earth removal conveyance part 72 May be configured with a screw such as a ribbon screw.
Moreover, although the earth discharge input part 73 in Embodiment 2 was provided with the shooter, this invention is not limited to this, The earth discharge input part 73 is provided with the belt conveyor. It may be configured.

The present invention is not limited to the second embodiment.
For example, as shown in FIG. 9, the soil removal processing device 70 does not include the second soil discharge transport unit 72 and the soil discharge input unit 73 (that is, a configuration including the first soil discharge transport unit 31). There may be.
If it is the soil removal processing apparatus 70 of such a structure, the soil moved to the side by the 1st soil removal conveyance part 71 (shooter) will be moved to the right side of the excavation apparatus 200 (pile press-fitting apparatus 50) in the moving direction ( In FIG. 9, it becomes possible to fill the pile row with backfill by putting it in the excavation hole in a landfill on the left side of the pile row.
Further, here, the pile row is backed by the first soil removal transport unit 71 (shooter), but the first soil removal transport unit 71 (shooter) and the second soil discharge transport unit 72 are provided. The pile row may be backfilled by the soil disposal apparatus 70 having the above-described configuration.
In addition, when applying backfill to the pile row formed by connecting piles on the slope, a slide for moving the scraper 31b forward and backward as in the soil removal processing device 30 (first soil conveyance unit 31) of the first embodiment. The soil may be reclaimed by a table or a belt conveyor.

As described above, with the soil removal processing device 30 and the soil disposal processing device 70 according to the present invention, it is not necessary to attach or remove the soil disposal processing devices 30 and 70 each time the excavator is moved. The burden on the worker can be reduced and the soil removal process can be saved. In addition, the construction period can be shortened.
Moreover, the crane for earth removal like a prior art is unnecessary, and even in the case of construction on the water, since the earth removal processing apparatus is self-propelled on a pile row | line | column with a digging apparatus, a temporary pier and a base boat become unnecessary. In other words, since labor costs and equipment costs can be suppressed, construction costs can be reduced.
In addition, if the excavated soil is backfilled in the steel pipe pile P or the pile row is backfilled, no soil is discharged from the site, which can contribute to environmental conservation. Become.

  The application of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.
