DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous pile driving system and a continuous pile driving method for continuously driving a structure such as a sheet pile or a pile, such as a sheet pile for earth retaining.

[0002]

2. Description of the Related Art Applicants have already developed a pile press-in / pull-out machine capable of driving a driving structure (hereinafter referred to as a "pile") such as a sheet pile or a pile for retaining a soil almost without noise and vibration. Such a pile press-in / pull-out machine is generally known. The above-mentioned pile press-in / pull-out machine is configured to be able to press-fit a pile or pull out a driven-in pile by hydraulic pressure in a state where a reaction force is taken from the already driven pile.

Further, the pile press-in / pull-out machine is designed to be held on a pile when a reaction force is taken from the already driven pile, and to be continuously connected like a sheet pile for retaining. When a stake was struck, it was possible to move on the stake along the stake that was sequentially driven. Therefore, the pile press-in / pull-out machine can move on the pile already driven in continuously as described above, for example, when driving a sheet pile for embankment on the riverbank. It is possible to stake without any equipment.

[0004] However, the pile press-in / pull-out machine is not provided with a hydraulic unit for supplying hydraulic pressure, a cockpit, or the like, for the purpose of reducing the size and weight and considering safety. In order to do this, it is necessary to provide support equipment such as the hydraulic unit, power generation unit that supplies electric power, and equipment (eg, scaffolding) for operators and workers to perform work. Pile supply equipment such as cranes and trucks is required.

Accordingly, in the construction for continuously driving piles by the pile press-in / pull-out machine as described above, even if the pile press-in / pull-out machine can move on the pile continuously driven alone, When there is no facility for moving and arranging equipment, materials, and personnel, temporary work to provide roads, work spaces, scaffolds, etc. is required, and this temporary work will increase construction costs and lengthen the construction period. .

Accordingly, the present applicants have developed a pile moving device capable of moving on a pile while holding a pile that has been driven in continuously, similarly to the pile press-in and pull-out machine, and a pile moving device. A crane that can move on a pile and a pile that transports materials such as piles on piles continuously driven by rails laid on piles that have been driven continuously Having an upper transfer device, a scaffold for operators and workers as well as having the above hydraulic unit and power generation unit,
In addition, an on-pile movement support device capable of moving on a continuously driven pile (for example, a on-pile movement scaffolding device,
766).

[0007] The above-mentioned pile press-in / pull-out machine, pile-mounting support device having a hydraulic unit, etc., pile-mounting work device which can move on a pile having a crane, etc. In addition to the piles that are transported by the pile transport device at the tip of the pile that is continuously driven, It is carried into the pile press-in / pull-out machine by the upper moving work device, and the hydraulic pressure is supplied to the pile press-in / pull-out machine from the above-mentioned pile moving-in support device. You will be driving a stake.

[0008] Further, since the above-described devices except the above-mentioned pile transfer device can move on the piles continuously driven as described above, the piles are sequentially driven and moved forward. Therefore, at the pile driving site at the tip of the pile that is continuously driven, besides laying the rails of the above-mentioned pile transfer device on the pile, temporary facilities for moving and arranging the above-mentioned support equipment and the like are provided. Since temporary work can be almost eliminated without the necessity, the construction cost can be reduced and the construction period can be shortened.

[0009]

The above-mentioned pile press-in / draw-out machine, pile-mounting support device, pile-mounting work device having a crane, and the like can be used alone, respectively. It was movable. However, when driving piles continuously as described above, these devices are used in cooperation with each other, and when each of them is moved alone, there are the following problems.

That is, when moving each device, it is necessary to operate each device individually, and each device arranged on a continuous pile is moving on one track. It is necessary to monitor the intervals between the devices, which requires a relatively large number of operators and operators. In addition, each device needs to be fixed and moved on a relatively unstable pile, for example, the pile press-in and pull-out machine and the pile moving work device have a plurality of gripping means for gripping the pile from right and left. , Has a slide mechanism for sliding the main body, and even during the movement, the other part is moved by the slide mechanism in a state where one or more gripping means grips the pile, so that the state is stable. Can move on the pile.

Incidentally, in the pile press-in / pull-out machine, the portion for press-fitting or pulling out the pile is also designed to grip the pile, which is a kind of gripping means. On the other hand, the above-described pile-mounting support device is configured to move on a pile with a roller so that the worker or the like can move smoothly without affecting the worker or the like with the worker or the like placed on the scaffold. In addition, the guide rollers sandwich the pile from the left and right so that the pile can move stably on the continuous pile. In the above-described pile-mounting support device, the guide roller can be moved by an actuator or the like in order to increase the stability, and the guide roller can be kept in close contact with the left and right side surfaces of the pile.

That is, when each of the above-mentioned devices can be moved independently, not only does a driving device for each device need to be provided, but also each device is stably and reliably supported on a pile. Therefore, there is a problem that the cost of each device is increased. In addition, when driving a pile as described above using the pile press-in / pull-out machine, the pile moving support device, the pile moving work device having a crane, and the pile moving device, the pile is moved behind the pile moving work device. It is necessary to lift the pile conveyed by the upper conveying device with the crane of the pile moving work device and set it on the first pile press-in / pull-out machine.

At this time, by rotating the boom of the crane from the state facing the rear of the pile-mounting work device to the front side, the pile is pressed into and pulled out from the rear of the pile-moving work device. Transporting the piles, it will take some time to transport the piles. In addition, in consideration of workability and safety, after the driving of one pile by the pile press-in / pull-out machine is completed, the pile is transported by the crane as described above, and the next pile driving will be performed. The transfer time of the pile is directly reflected in the construction period, which is a factor of lengthening the construction period.

The present invention has been made in view of the above circumstances, and provides a continuous pile driving system and a continuous pile driving method capable of saving labor when driving piles continuously and shortening the construction period. The purpose is to do so.

Two first brackets 31, 31 fixed to the base 26 of the pile moving work device 21 and arranged vertically, and vertically arranged with the upper and lower ends joined to the first brackets 31, 31 A connection shaft 32 having a cylindrical shape, and two upper and lower second brackets 34 having through holes 33, 33 through which the connection shaft 32 passes, and being fixed to the base frame 14 of the on-pile moving scaffolding device 11; 34.

The two first brackets 31, 31
The interval between the two second brackets 34, 34 is in a state where there is a margin up and down. That is, the coupler 30 has sufficient play up and down, so that the coupler 30 can absorb even if the position of the on-pile moving scaffolding device 11 and the position of the on-pile moving work device 21 are vertically displaced. .

The through holes 33, 33 of the second brackets 34, 34 are elongated holes extending in the front-rear direction of the on-pile moving scaffolding device 11 and the on-pile moving work device 21,
The connection shaft 32 can move back and forth with respect to the second brackets 34, 34. That is, the coupler 30
Has enough play before and after. Therefore, the space between the pile-mounted moving scaffolding device 11 and the pile-mounted moving work device 21 can be separated or approached to some extent.

The coupler 30 is provided on the scaffold moving scaffolding device 1.
Since there is almost no play in the left and right directions of the pile moving work device 21 and the pile moving work device 21, a force to move the pile moving scaffolding device 11 left and right works while the pile moving work device 21 is fixed on the piles P. However, the pile-moving scaffolding device 11 cannot move left and right or tilt left and right. That is, the on-pile moving scaffolding device 11 is supported by the on-pile moving operation device 21 via the coupler 30 so as not to fall from the top of the piles P or to tilt left and right on the piles P. .

Next, a continuous pile driving method using the continuous pile driving system having the above configuration will be described.
First, at a stage where the piles P... Are driven in parallel into the ground by the pile press-in / pull-out machine 1 to some extent, as shown in FIG. The moving scaffolding device 11 and the pile moving work device 21 are arranged in this order. In addition, if necessary, a pile transport device having a track (not shown) is arranged on the piles P...

Then, the crane section 2 of the on-pile moving operation device 21 is placed on the pile mounting portions 16 of the on-pile moving scaffolding device 11.
5, the pile P 'is carried in, and the pile P' is placed on the on-pile moving scaffolding device 11. In this case, the pile moving work device 21
Even if the pile P ′ is carried in from the ground side by the crane unit 25 of the above, the pile-mounting operation device 21
May be carried in the pile P ′ transported to the rear of the vehicle.

In this case, a plurality of, for example, about five stakes P are carried in at one time, so that the work time can be reduced. Next, the piles P are sequentially and continuously driven by the pile press-in / pull-out device 1. In this case, the crane section 25 of the pile-mounting work device 21 loads the piles of the pile-moving scaffolding device 11. Only one pile P ′ on the sections 16, 16 is lifted and moved to the chuck 6 side of the pile press-in / puller 1, and the pile P ′ is vertically raised, and the chuck 6
Stake P '.

When the pile P ′ is transported from the pile mounting sections 16, 16 of the on-pile moving scaffolding device 11 to the chuck 6 of the pile press-in / pull-out device 1, the crane section 25 is directed substantially forward. This can be done with little turning of the part 25. Therefore, for example, as in the case of transporting the piles P ′ transported by the pile transport device one by one to the chuck 6 of the pile press-in / pull-out machine 1 behind the pile transport operation device 21,
There is no need to rotate the crane 25 almost 180 degrees,
Since the pile P 'can be set in the pile press-in / pull-out machine 1 in a relatively short time, the construction period of the operation for continuously driving the piles P ... can be shortened.

As described above, when the pile P ′ is transported from the pile mounting sections 16, 16 of the on-pile moving scaffolding device 11 to the chuck 6 of the pile press-in / pull-out device 1, the piles P ′,. Although it is necessary to carry the piles 16 on the pile-moving scaffolding device 11 at this time, a plurality of piles can be carried in at one time. The time is short. Therefore, one by one, the crane unit 25
Is rotated at a large angle, and the piles P ′ are moved into the pile press-in / pull-out machine 1 from behind or from the side of the pile moving work device 21, and the piles P ′. 1
After the pile P ′ has been carried into the pile mounting section 16,
The construction period can be greatly reduced by carrying the material from 16 into the chuck 6 of the pile press-in / pull-out machine 1.

When the pile P ′ is lifted from the pile mounting portions 16, 16 of the on-pile moving scaffolding device 11, the pile P ′ is set up along the left and right sides of the power unit 12 of the on-pile moving scaffolding device 11. Since the pile P 'can be lifted along the guard members 18 provided, the pile P' does not rotate during the lifting, and does not swing due to the wind. Therefore, during lifting, it is possible to prevent the pile P ′ from rotating or swinging and hitting the structure of the on-pile moving scaffolding device 11 and to ensure the safety of workers and operators on the scaffolds 17, 17. Can be improved.

Next, the pile press-in and pull-out machine 1 presses the pile P into the ground. After the setting of the pile P ′ into the pile press-in / pull-out machine 1 and the press-fitting of the pile P are repeated several times as described above, the pile press-in / pull-out / pull-out machine 1, the on-pile moving scaffolding device 11, and the on-pile moving work device 21 To move forward. At this time, the pile press-in / pull-out machine 1 and the on-pile moving operation device 21 run by themselves as described above, and the on-pile moving scaffolding device 11 connected to the on-pile moving operation device 21 is connected via the coupler 30. Pile moving work device 21
To be pushed forward.

Since the on-pile moving operation device 21 and the on-pile moving scaffold device 11 are connected, the on-pile moving operation device 21 and the on-pile moving scaffold device 11 can be moved by one person. Therefore, there is no need to monitor the distance between the on-pile moving work device 21 and the on-pile moving scaffold device 11. Therefore, labor saving of continuous pile driving can be achieved.

Also, the first and second clamps 22 and 23
Is moved to the pile moving work device 21 which is disposed in an extremely stable state on the pile P by the
1 are connected, it is possible to arrange the on-pile moving scaffolding device 11 on the piles P in an extremely stable state. Further, as described above, since the coupler 30 has sufficient play in the up-down direction and the front-rear direction, and has little play in the left-right direction, the pile-moving scaffolding device 11 moves left and right. Can be prevented, and even if the tops of the piles P driven in parallel are slightly irregular, and the pile-moving scaffolding device 11 traveling on the pile P swings up and down, The vertical swing is absorbed by the coupler 30 having a sufficient play in the front and rear directions, so that a large load is not applied to the coupler 30.

Then, as described above, the pile P is transferred from the on-pile moving scaffolding device 11 to the pile press-in / pull-out machine 1 by the on-pile moving work device 21, the pile is pressed in by the piling press-in / pull-out device 1, and the pile is pressed into Pulling machine 1 and pile-mounted moving scaffolding device 1 connected to each other
The piles P can be driven continuously by sequentially repeating the movement of the pile 1 and the pile moving work device 21.

As described above, according to the continuous pile driving system and the continuous pile driving method according to the embodiment of the present invention, the on-pile moving operation device 21 and the on-pile moving scaffold device 11 are connected. A driving device for traveling of the on-pile moving scaffolding device 11 can be omitted, and support means such as the guide portion 15 for supporting the on-pile moving scaffolding device 11 on the pile can be simplified, and the on-pile moving scaffolding device can be moved. The equipment cost of the scaffolding device 11 can be reduced.

Even if the supporting means of the on-pile moving scaffolding device 11 is simplified, the on-pile moving scaffolding device 11 is supported by the connected on-pile moving scaffolding device 21 so that the on-pile moving scaffolding device 1 is supported.
1 can be improved in stability. Further, since the on-pile moving work device 21 and the on-pile moving scaffold device 11 are connected, a single operator can move the on-pile moving scaffold device 11 and the on-pile moving work device 21 when moving. In addition, there is no need to monitor the interval between the on-pile moving scaffolding device 11 and the on-pile moving work device 21 so that they do not collide with each other, and it is possible to further save labor.

Further, the coupler 30 for connecting the on-pile moving scaffolding device 11 and the on-pile moving work device 21 has sufficient play in the up-down direction and in the front-rear direction, and has little play in the left-right direction. As a result, it is possible to prevent the on-pile moving scaffolding device 11 from moving left and right or tilting to the left and right with respect to the on-pile moving working device 21, and the on-pile moving scaffolding device from the When the 11 moves up and down and back and forth, it can be absorbed by the play of the coupler 30 to prevent a large load from being applied to the coupler 30.

In supplying the piles P ′ to the chuck 6 of the pile press-in / pull-out machine 1, a plurality of piles P ′ are once placed on the pile placing portion 16 of the pile moving scaffolding device 11, The placing section 16 is moved by the crane section 25 of the mobile work apparatus 21.
Since the pile P is transferred to the chuck 6 of the pile press-in / pull-out machine 1 from above, the pile P can be set in the pile press-in / pull-out machine 1 without turning the crane 25 almost in a state of facing the front. The time required for setting the piles P can be greatly reduced, so that the construction period of the pile driving operation can be significantly reduced.

Further, the pile mounting portion 1 of the on-pile moving scaffolding device 11
When lifting and moving the pile P from the guard member 1,
Since the pile P can be lifted in a state in which the pile P is along 8, 18, it is possible to prevent the pile P from rotating or being swung by the wind during lifting. Therefore, the power unit 1 of the on-pile moving scaffolding device 11 is driven by the suspended pile P.
2 can be prevented from being damaged, and safety can be improved.

The above example is one embodiment of the present invention, and various design changes are possible. For example, the on-pile moving scaffolding device 11 and the on-pile moving work device 21 are integrally and firmly connected. A connection drive, a driving device for traveling is provided on the side of the pile-based moving scaffolding device 11 instead of the pile-mounted moving working device 21, or the pile-mounted moving scaffolding device 11 and the pile-mounted moving working device 21 are connected, and The drawing machine 1 may be detachably connected to these.
