ふえ施工原価が上がるという問題点を有していた。 （３）杭の頭部が小さいので熟練した作業者でなければ
杭打ちができず未経験者では作業が困難で作業性に欠け
るという問題点を有していた。However, the above-described conventional pile driving method and pile driving auxiliary tool have the following problems. (1) When the pile is directly hit with a hanging arrow, the head of the pile is small, so it is difficult to hit the head accurately and workability is poor.
Further, there is a problem in that the side portion of the pile is apt to be damaged by hitting the center portion of the pile and the appearance of the pile is bad, so that the pile needs to be replaced with a new pile. (2) Since the piles are easily damaged when hit, there is a problem in that the number of piles used increases and the construction cost increases. (3) Since the head of the pile is small, only a skilled worker can drive the pile, and an inexperienced person has difficulty in working and lacks workability.

Examples of the shape of the striking surface include a square shape, a circular shape, and a polygonal shape. The striking surface of the striking part has an area of 10 compared to the striking surface of the pile.
~ 250%, preferably 30-150% wider. As the area of the striking surface becomes less than 30% of the area of the striking surface of the pile, the effect of widening the striking surface to make it easier for the worker to strike is not preferable. Also,
When the area of the striking surface exceeds 150% of the striking surface of the pile, the pile tends to tilt when striking the pile, which is not preferable. As the material of the striking part, wood such as red pine, black pine, beech, bay pine, cedar, pine, and cypress is preferably used. Woods such as red pine, black pine, beech, bay pine, cedar, pine, and cypress have strength and toughness that are not destroyed even when hit, and thus are preferably used. In addition, a polyolefin such as polyethylene having impact resistance or a synthetic resin such as ABS, polycarbonate or polyamide may be used.

It is formed in a circular shape, a polygonal shape, or the like. The striking support portion is formed in the same shape as the striking portion, but the fixing portion (peripheral wall portion) surrounding the striking member may be integrally formed. The striking support portion and the pile head fitting portion may be integrally formed. The material of the striking support portion is carbon steel material, alloy steel material, metal material such as aluminum material, polyamide, polyimide, PPO, ABS,
It is possible to use a synthetic resin such as polyethylene or polypropylene, or an FRP such as unsaturated polyester in which organic resin such as carbon fiber, SiC fiber, boron fiber or nylon fiber is mixed with these. When the striking support portion, the pile head fitting portion and the striking portion are formed separately, they are fixed with screws, screws or the like, or fixed with an adhesive or the like. Further, when the fixing portion is provided upright by surrounding the striking portion from the outer peripheral portion of the striking support portion, the fixing holes are punched at predetermined intervals in the fixing portion,
The striking portion may be fixed to the striking support portion by inserting the fixing portion into the fixing hole.
