Half-slope pile mechanical rotary excavating construction method and hole cleaning device thereof
The invention provides a half-slope pile mechanical rotary excavating construction method which comprises the following steps: supporting a side slope, building a construction platform based on the side slope support, backfilling and compacting the construction platform, installing a guide ring in a to-be-drilled area, rotatably excavating a pile foundation hole in the to-be-constructed area by a rotary excavating machine, and cleaning the pile foundation hole. A hole cleaning device is adopted to clean the hole bottom of a pile foundation hole, a reinforcement cage is placed into the pile foundation hole excavated by a rotary drilling machine, the reinforcement cage placed to the designed position is fixed, concrete is poured into the pile foundation hole to form a pile, and a pile head is leveled and maintained after the concrete is initially set. And sediment at the bottom of the pile foundation hole is not easy to remove.
本发明提供了一种半坡桩机械旋挖施工方法,包括以下步骤，对边坡进行支护，基于边坡支护搭建施工平台,对施工平台回填压实,在待钻挖区域安装导向环后，旋挖机对待施工区域旋挖桩基孔,对桩基孔进行清孔，采用清孔装置对桩基孔的孔底进行清洁,向旋挖机挖出的桩基孔内下放钢筋笼,将下放到设计位置的钢筋笼进行固定,向桩基孔内浇筑混凝土成桩,待混凝土初凝后对桩头整平并养护，其解决了现有技术中存在的对桩基孔清孔时，桩基孔孔底的沉渣不易清除的问题。
