Claims (2)
- 自由落下によって杭を打撃する杭の載荷装置であって、重錘部と、その重錘部の上部に取り付けられる突起部と、その突起部の内部に収容される計測部とを備え、
前記計測部は、枠部の上部と下部に一端がそれぞれ連結された上下のバネ部間に配置されるスライド部と、そのスライド部の上方及び下方にそれぞれ配置される指示部と、その指示部を落下させることなく支持させる保持手段とを備えることを特徴とする杭の載荷装置。 - 請求項1に記載の杭の載荷装置によって杭を打撃することで杭の支持力を測定する杭の施工方法において、
円筒状の軸部より外形が大きな板状の羽根部を先端部に備えた杭を地中に埋設し、前記杭の内空に設けられた打撃部よりも上方に吊った前記載荷装置を自由落下させてその打撃部を打撃し、前記載荷装置を前記杭の内部から取り出して前記計測部に記録された指示部の位置から前記杭の支持力を確認し、支持力が所定の支持力に達していないと判定されたときには、前記載荷装置によって再び前記打撃部を打撃して支持力不足を解消させることを特徴とする杭の施工方法。
