ON-SITE CONSTRUCTION METHOD FOR FOUNDATION PILE
To easily construct a foundation pile even in a narrow site without using a large-sized pile driver having a long leader, with reduced noise and vibration, and enable on-site construction of a foundation pile having a required diameter; and to provide a foundation pile which has high pull out strength or has high quality.SOLUTION: An on-site construction method for a foundation pile uses a launcher which connects a vertical type propulsion machine and a subsequent steel pipe to a foundation pile installation scheduled ground surface and starts the machine and steel pipe in a vertical direction and allows the machine and steel pipe to be recovered to the ground. The method feeds excavated waste soil taken in from a hydraulic jack device and an excavator to the ground with a soil discharge pipe, kneads the sent excavated waste soil with a solidification material, pressure-feeds the kneaded material as a solidified body into a pipe of the soil discharge pipe and fills a drilled hole with the solidification material, and lifts the material to the ground side while stirring the material with a cutter part of the excavator, and recovers the material.SELECTED DRAWING: Figure 19
【課題】 大型でリーダーの長い杭打機等を使用せずに狭い現場でも容易に基礎杭を構築でき、騒音・振動が少なく、所要径の基礎杭の現場構築を可能とする。又、基礎杭の引抜強度は高く、又品質の高い基礎杭を提供できるようにする。【解決手段】 基礎杭の打設予定の地面に縦型推進機とその後続の鋼管をフランジ連結して鉛直方向に発進させ、及び地上へのこれらの装置を回収する発進台と、油圧ジャッキ装置及び掘進機から取り込んだ掘削排土を排土管で地上に送り出し、これに固化材を混練して固化体として排土管の管内に圧送して削孔内に固化体を充填するとともに、掘進機のカッター部で撹拌しながら地上側に持ち上げて回収する。【選択図】図１９
