Description

杭打ち、ユニットの組み立て、ワイヤーに吊り上げてのユニットの移動、杭とユニットの接合からなるユニット工法であって、
杭が、らせん構造とボルト接続用の孔を設けた円筒状の頭部を有するスクリュー杭であって、
杭打ちは、リーダーの接地面が表面に突起が形成されたＲを有する面状の接地面であるリーダー式杭打ち機を使用して、垂直方向を維持しながら重機により４本１組で杭を打ち込み、
ユニットは４本の支柱と４本のユニット構成枠を含む構造で組み立てられていて、
ユニットは、ワイヤーで吊り上げられて、ユニットの４本の支柱を垂直に維持して、４本１組のスクリュー杭頭部へ移動し、
杭とユニットの接合は、ユニットの支柱脚部がスクリュー杭の円筒状の頭部に差し込まれ、ボルトとナットがスクリュー杭の円筒状の頭部の外から地面と水平に締め付けられる接合構造であるユニット工法により達成される。 Piling, assembly of units, mobile units of lifting the wires, a unit construction method a cemented pile and units,
The pile is a screw pile having a cylindrical head with a spiral structure and a hole for bolt connection,
Piling uses planar ground plane Der Ru reader type pile driver having R to the ground plane of the reader protrusions formed on its surface, with four set by heavy machinery while maintaining the vertical direction Driving a pile,
The unit is assembled with a structure that includes four columns and four unit frames.
The unit is lifted by a wire and moves to a set of four screw pile heads, keeping the four struts of the unit vertical,
The pile and unit are joined by a structure in which the column base of the unit is inserted into the cylindrical head of the screw pile, and the bolt and nut are tightened horizontally from the outside of the cylindrical head of the screw pile. Achieved by unit construction method.
