[Industrial applications]

 The present invention is a pile driving machine for driving a pile of steel sheet pile or H-shaped steel, etc. by a pile driving machine equipped on a moving vehicle such as a crane or a backhoe, and a pile driving for guiding a driving location or a driving location. It is related to the gauge.

[0002]

[Prior art]

 As an example of the pile driving work using vibro etc. in civil engineering work that has been known in the past, one end of the work arm is mounted on a machine body with a turning mechanism interposed on a crawler type self-propelled vehicle. It is mounted on the tip of this work arm, and the built-in swivel mechanism that is tiltable in the front-back and left-right directions is used to detachably mount the pile driver body, which can be swiveled in the horizontal direction. Pile driving work is carried out by tilting and turning the work arm.

In the pile driving work using the above-mentioned vibro, etc., since the pile driver main body hung from a crane or a hydraulic excavator exists in the air, the pile of steel sheet pile or the like can be straightened or desired. It is difficult to drive along the curved shape, and it is not possible to cope with work requiring high accuracy such as revetment work. Therefore, in general, a guide member in which general steel or H-shaped steel is lined up is provided at the portion of the steel sheet pile that comes into contact with the ground, which improves the driving accuracy of the pile.

[0004]

[Problems to be solved by the device]

 However, such a conventional means for using a guide member in which steel materials are arranged is not suitable for construction that requires high accuracy and lacks accuracy, and the guide members are arranged before the start of construction. There is a problem that the pile driving work itself becomes extremely troublesome because the preparation work such as the above is required and the work for removing these members is required even after the completion of the work.

Particularly when piles are to be placed on the water such as river construction or revetment construction, the guide member itself cannot stand on its own, so scaffolding using temporary materials or erection work for guide construction is required separately. There is a problem in that construction must be done, which leads to an extension of the implementation period and an increase in construction costs.

Therefore, the present invention solves the problem that the conventional guide member is used to improve the driving accuracy of the pile, and eliminates the preparatory work before and after the construction start and the member removal work. A gauge for pile driving that can shorten the implementation period and lower the construction cost by using a gauge that enables self-standing with respect to existing piles even when driving piles on the water. It is intended to provide.

To be

Next, with reference to FIGS. 6 and 7, the configuration and operation of the adjusting mechanism for changing the distance between the mounting bases 1 and 1 and the gauge bodies 2 and 2 will be described. That is, on the upper surface of the installation base 1 on one side, guide members 16, 16 having an inverted L-shaped cross section that extend in the left-right direction are fixed in parallel, and at the intermediate portion of the guide members 16, 16, and A weld nut 17 is welded near the end of the mounting base 1.

FIG. 7 is a sectional view taken along the line AA of FIG. 6 at the time of assembly, in which the bolt shaft 20 is threadedly engaged with the weld nut 17 from the female screw 19 through the hollow clamp device 3. The square hole 15a of the manual handle 15 can be fitted into the corner portion 20a formed at one end of the bolt shaft 20. The mechanism for adjusting the distance between the gauge bodies 2 and 2 is also substantially the same.

In the above embodiment, the mounting bases 1 and 1 are arranged in parallel to each other in the left and right direction, and the pair of gauge bodies 2 and 2 are tilted in the left and right directions at positions extending along the longitudinal direction of the mounting bases 1 and 1. Although the example in which the gauge body 2 is freely attached is disclosed, the present invention is not limited to the above-mentioned configuration. For example, one installation base 1 on which the gauge body 2 is axially attached and the installation base 1 in the longitudinal direction are attached. A gauge main body 2 that is axially attached so as to be tiltable in the left-right direction at a position that extends along it, a clamp device 3 for an existing pile that is fixed to the installation base 1, and a gauge main body 2 in normal times. It may be a pile driving gauge that is housed inside and has an extension gauge 7 that extends in the longitudinal direction of the gauge body 2 when used.

The basic operation mode of this embodiment will be described below. First, prior to pile driving work, work is performed to adjust the distance between the installation bases 1 and 1 and the gauge bodies 2 and 2 according to the purpose of the work. When the rotating operation of the manual handle 15 is performed by the operation of the worker, as shown in FIG. 7, the square hole 15a of the handle 15 and the square section 20a formed at one end of the bolt shaft 20 are fitted to each other. As the bolt shaft 20 rotates, the bolt shaft 20 and the weld nut 17 welded near one end of the installation base 1 and the female screw 19 fixed to the lower end of the clamp device 3 are screwed together. The protrusions 18 and 18 of the clamp device 3 shown in FIG. 6 slide in the guide members 16 and 16, and the space between the mounting bases 1 and 1 and the gauge bodies 2 and 2 is adjusted arbitrarily.

Next, using a crane or the like, the pile driving gauge according to the present embodiment is suspended above the driving position of the pile, and the clamp device 3, which is fixed to one side of the installation base 1, 1. 3 is firmly clamped to the existing pile 9.

Next, the gauge main bodies 2 and 2 axially attached to the front of the installation bases 1 and 1 are appropriately tilted in the left and right directions with the hinge pins 6 and 6 as fulcrums, and the gauge main bodies 2 and 2 are bridged in the vicinity of the front ends. The space of the gauge notch 8 is adjusted by engaging the notch 13 of the connecting arm 5 attached in a tangled state with one of the pins 14 and 14. In addition, in the case of driving piles on the water for revetment work, etc., before the clamp device 3 of the installation base 1 is clamped to the existing piles 9, the tilting operation of the gauge bodies 2 and 2 is performed in advance. Is good.

Further, according to the specifications of the construction, the extension gauges 7 and 7 attached as a state of being housed in the gauge bodies 2 and 2 are horizontally arranged with the extension gauge pins 11 and 11 as fulcrums as shown in FIG. Or rotate the extension gauges 7, 7 linearly as shown in FIG. 5 to widen the work area during pile driving. In this way, by performing the tilting operation of the gauge main bodies 2 and 2 and the extension operation of the extension gauges 7 and 7, it is possible to perform pile driving work while preventing interference due to passage of the built-in pile 10.

When a certain number of pile driving operations are completed, the clamps of the installation bases 1 and 1 for the existing piles 9 are released and the pile driving gauge is used up to the next existing pile using a crane or the like. It is possible to continue the pile driving work by moving and again clamping the clamp device 3 to the existing pile 9. When all the pile driving work is completed, the clamps of the installation bases 1 and 1 for the existing piles 9 are released, the pile driving gauge is removed again using a crane, and the pile driving gauges are loaded into a small-sized vehicle. Carry.

Therefore, in the pile driving gauge according to the present invention, the distance between the installation bases 1 and 1 and the gauge bodies 2 and 2 can be appropriately adjusted according to the situation of the construction site and the purpose of the construction, and A major feature of the operation is that by performing the expansion and contraction operation of the extension gauges 7 and 7, the pile driving work is performed while preventing the interference due to the passage of the built-in pile 10.

[0028]

[Effect of device]

 As described in detail above, in the pile driving gauge according to the present invention, the space between the installation base and the gauge body can be arbitrarily adjusted by rotating the manual handle according to the construction purpose. Moreover, the space between the gauge bodies is adjusted by properly tilting the gauge body, which is attached to the front of the installation stand, in the left-right direction after the clamp device of the installation stand is clamped on the existing pile, By extending the stored extension gauge in the longitudinal direction of the gauge body, it is possible to carry out the desired pile driving work according to the construction specifications while preventing interference due to the passage of the built-in pile.

Therefore, unlike the conventional means using a guide member in which steel materials are simply arranged, the preparatory work such as arranging the guide members before the construction work and the work of removing the members after the construction work are unnecessary, and the pile driving work itself. In addition to being extremely simplified, it is possible to deal with construction work that requires high accuracy because the location of pile driving is accurate.

Even when piles are placed on the water, such as in river construction or revetment construction, since the installation stand can be self-supporting for existing piles, temporary construction materials and erection construction for guide construction can be performed. Since there is no need to construct it, work efficiency is improved, and because small piles are sufficient for carrying the pile driving gauges, lighter loading and unloading is possible and mobility is high, shortening the implementation period and transport costs. As a result, the construction cost can be reduced.
