Rectangular hole drilling machine for cast-in-situ bored pile and construction method
The invention discloses a rectangular hole drilling machine for a cast-in-situ bored pile and a construction method, solves the problem that in the prior art, a drilling machine can only excavate a circular drill hole, and has the beneficial effects of achieving rectangular drill hole excavation and improving the drilling efficiency, according to the specific scheme, the rectangular hole drilling machine for the cast-in-situ bored pile comprises a supporting seat and a supporting seat supporting and lifting mechanism; the lifting mechanism is connected with the reciprocating drilling tool body; the reciprocating type drilling tool body comprises an arm body, the arm body supports at least two transmission excavation mechanisms, the number of the transmission excavation mechanisms is an even number, the transmission excavation mechanisms are arranged around the longitudinal direction of the arm body, each transmission excavation mechanism comprises a driving wheel and a driven wheel, and the transmission part bypasses the driving wheel and the driven wheel. The moving directions of the transmission parts in every two adjacent transmission excavation mechanisms are opposite, the transmission parts movably support a plurality of excavation parts, a stop block is arranged on the top side of the arm body, and after one end of each excavation part makes contact with the stop block, the excavation parts can swing relative to the transmission parts so as to dump soil or bed rock at the excavation parts.
本发明公开了一种钻孔灌注桩用矩形孔钻机及施工方法，解决了现有技术中钻机只能开挖圆形钻孔的问题，具有实现矩形钻孔开挖，提高钻孔效率的有益效果，具体方案如下：一种钻孔灌注桩用矩形孔钻机，包括支撑座，支撑座支撑提升机构，提升机构与往复式钻具本体连接；往复式钻具本体包括臂体，臂体支撑至少两组传动开挖机构，传动开挖机构的数量为偶数，传动开挖机构环绕臂体的纵向方向设置，每一组传动开挖机构均包括主动轮和从动轮，传动件绕过主动轮和从动轮设置，相邻两组传动开挖机构中传动件的运动方向相反，传动件活动支撑有多处开挖件，臂体的顶侧设置挡块，开挖件的一端与挡块触碰后，可相对于传动件摆动以将开挖件处的土体或基岩进行倾倒。
