By the way, the ground is generally composed of a hard topsoil layer having a thickness of about 1.5 m and a soft layer below the topsoil layer. If you try to place a pine pile up to such a soft layer of the ground with the vibration of a vibro hammer, a strong placing force is required until the pine pile penetrates the topsoil layer, so the ground will vibrate, so the house Placing work of pine piles with a vibro hammer is regulated in the ground and urban areas. Therefore, since it is not possible to place pine piles with a vibro hammer in a residential area or an urban area, the work efficiency of this type of pile laying work is poor, and the construction period of the foundation work for building a house in a residential area or urban area is long. There was a problem to be solved.

Then, while maintaining the work arm 4 at a predetermined position, hydraulic oil is supplied to the hydraulic motor M 2 for rotating the drill so that the drill 14d is drilled through the small gear 14b and the large gear 14a.
When the hydraulic oil is supplied to the swivel joint 14c and the pressing force is applied to the drilling drill 14d through the telescopic cylinder working cylinder 14g while rotating the rotating drill, the drilling drill 1
By 4d, a pile driving hole is drilled in the surface soil layer of the ground. In such a drilling operation of a pile driving hole in the topsoil layer, since the drilling drill 14d is simply rotated while exerting a pressing force, it penetrates the topsoil layer having a thickness of 1.5 m without vibrating the ground. The pile driving hole can be drilled with high efficiency.

In this way, when the pile driving hole penetrating the topsoil layer is drilled, the telescopic cylinder operating cylinder 14g is reduced, and the pine pile is set in the pile driving hole with the tip end facing downward. The working arm 4 is operated again to bring the contact portion 13a of the vibro hammer 13 into contact with the pile head of the pine pile. Next, hydraulic oil is supplied to the vibro hammer operating hydraulic motor M 1 to rotate the eccentric rotating body 13b to generate vibration, and the work arm 4 causes the vibro hammer 1 to the pine pile.
By applying a downward pressing force via 3, the pine pile is driven into the ground. Such a vibro hammer 1
In the work of placing pine piles according to No. 3, pile-drilling holes have already been drilled in the hard topsoil layer, and since the lower layer of the topsoil layer is a soft layer, a small placing force is sufficient, so a large vibration is applied to the ground. It is possible to drive a pine pile to a predetermined depth without causing it.

As described in detail above, according to the wood pile driving attachment according to the present invention, after a pile driving hole is drilled through the hard topsoil layer by the drilling device, the pile driving hole is formed in the hole. A wooden pile is set up, and the set up wooden pile is driven by a vibro hammer to the soft layer below the topsoil layer. Therefore, since a weak driving force is sufficient and a large vibration does not occur on the ground, it is possible to drive a wooden pile with high efficiency in a residential area or an urban area without being restricted by regulations. It can greatly contribute to the shortening of the construction period of the foundation work for building a house in.
