- 地上に設置される旋回動機により中空杭に回転を与えつつ地中に押入し、中空杭内の土砂を掘削してソイル柱とする中空杭建込み施工に用いる中掘り装置であって、
前記旋回動機により駆動され前記中空杭と共に回転可能であり、吊持手段により回転および上下動自在に支持される駆動部保持用ケーシングと、
このケーシングの内部縦方向に固設されたガイドレールと、
このガイドレールに上下摺動自在に装着され、前記駆動部保持用ケーシングと一体的に回転する汎用の駆動部と、
この駆動部の出力軸に連結され下端に掘削ヘッドを有する掘削ロッドと、
一端が前記駆動部に結合され他端が前記駆動部保持用ケーシングの下部に結合された少なくとも左右一対の圧入用油圧シリンダと
を備え、
前記駆動部保持用ケーシングの下部に中空杭の上端を連結可能とするとともに前記圧入用油圧シリンダの短縮動により前記駆動部を前記掘削ヘッドで掘削可能に圧下自在とした
ことを特徴とする中空杭建込み施工用中掘り装置。 - 前記駆動部保持用ケーシングは、前記吊持手段により吊持される上部ケーシングと、この上部ケーシングに上下方向摺動自在に外嵌され前記圧入用油圧シリンダの下端が結合される下部ケーシングとで構成され、前記上部ケーシングの内部縦方向にガイドレールを固設してこれに駆動部を上下方向摺動自在に装着し、前記駆動部の下降時に上部ケーシングが共に下降するように構成されている請求項1記載の中空杭建込み施工用中掘り装置。
- 前記駆動部保持用ケーシングを吊持する吊持具に、グラウトを前記駆動部および掘削ロッド内を通じて前記掘削ヘッドに供給するためのグラウトスイベルと、前記圧入用油圧シリンダに圧油の給排を行うための油圧スイベルと、前記駆動部のモータに給電するための給電スリップリングとが設けられている請求項1または2記載の中空杭建込み施工用中掘り装置。
