| description | The invention discloses a construction device and method for existing pile foundation obstacle clearing, and relates to the technical field of existing pile foundation obstacle clearing. The problem that in the existing pile foundation obstacle removing process, a steel sleeve is inconvenient to recycle after being welded is solved. The device comprises a bearing steel plate, a full-rotation full-casing drilling machine and a steel casing mechanism. The outer wall of the bottom end of the bearing steel plate is arranged on a foundation; uniformly distributed bearing steel blocks are fixedly connected to the outer wall of the top end of the bearing steel plate; the outer wall of the bottom end of the full-rotation full-casing drilling machine is fixedly connected to the outer wall of the top end of the bearing steel plate. The method comprises the steps that a bearing steel plate is installed beside an existing pile foundation, and a bearing steel block and a full-rotation all-casing drilling machine are insta |
