Description

Side gripping type vibrating pile driver {SIDE GRIP TYPE VIBRATORY PILE DRIVER}

The present invention relates to a vibrating pile driver, and more specifically, it can be used in combination with the side of an existing hammer device, and is driven while holding the side of various piles such as a sheet pile, H-beam IH beam or round pile. It relates to a side gripping type vibrating pile driver that can do the job.

In general, in order to build all structures such as concrete structures, bridges, or dams on the ground, it is necessary to carry out the foundation work of burying concrete piles, steel pipe piles, H-beams, etc. so that the ground can withstand the weight of the structure. .

Construction of such piles is very important in constructing structures and buildings. In particular, in the case of soft ground, it is necessary to carry out the foundation work to fix the pile by driving it into the bedrock in the basement below the surface of the earth. In such foundation work, the operation of driving piles into the ground is called driving work.

Usually, ready-made piles such as RC piles, PC piles, and steel pipe piles are widely used in the basic construction of structures such as bridges, ports, and buildings, and these ready-made piles are installed after driving with a hammer or drilling with an auger. Except for cases where the influence of the surrounding environment must be considered, the effective driving type construction is mainly applied in terms of economic feasibility and constructability.

In general, the driving machine is used to drive steel pipe piles or concrete piles with drop hammers, diesel hammers, vibro hammers, etc. by attaching an attachment to hit the piles to the crane. It is mainly used for driving the beam.

Recent driving work mainly uses a method of vibrating the chuck in the driving direction, that is, perpendicular to the pile by operating a vibrator while the pile is fixed to the chuck. Vibration of these piles reduces the friction between the pile and the ground, By giving, it is possible to make a smooth driving operation.

This driving operation is performed by drilling a pile hole in the ground, inserting a pile into it, and then applying a blow or vibration to the pile with a vibrator hammer or the like.

However, the conventional driving operation has several problems in terms of workability or efficiency.

For example, after making a hole in a pile such as an H-beam, the operator manually connects the chain to the hammer with a vibrator, and then lifts the file vertically and then inserts it into the pile hole, so hanging the chain on the pile, etc. There are problems in overall workability such as very inefficient work and a lot of work time.

In addition, there is a problem that may pose a risk to the safety of workers, such as the need to accurately align the file to the location of the pile ball with the assistance of the worker because the file continues to shake even when the vertically lifted file approaches the pile ball.

And, since the conventional vibro hammer has to hold the end of a pile such as an H-beam and drive it by lifting it, the hammer must maintain a height enough to lift a long pile, and in order to manufacture such a hammer, a complicated machine There was a problem in having a structure or having to provide additional parts.
