Distance-adjustable two-shaft bidirectional stirring drilling machine and construction method
The interval-adjustable two-shaft bidirectional stirring drilling machine comprises a sliding frame, a drill rod assembly, a drill bit assembly and power heads, the two same power heads are hung at the lower end of the sliding frame, and each power head comprises a power source, a box body, a transmission gear set, a pitch changing mechanism and an output shaft assembly; the distance between the two power heads can be changed through the distance changing mechanism, the distance changing mechanism is provided with a magnetostrictive displacement sensor, the displacement variation of the piston rod relative to the oil cylinder can be measured in real time, and the center distance of output shaft assemblies of the two power heads after distance changing can be locked unchanged; an output shaft assembly extending out of the lower end of the box body drives an inner rod and an outer rod of the drill rod assembly to rotate forwards and reversely, and then the inner rod and the outer rod drive a drill bit of the drill bit assembly to rotate and stir bidirectionally. According to the two-shaft bidirectional stirring drilling machine with the adjustable distance and the construction method, the distance from the middle to the middle of the bidirectional stirring pile can be flexibly adjusted, and the construction efficiency of the high-quality stirring pile can be greatly improved.
本发明涉及一种间距可调的两轴双向搅拌钻机及施工方法，包括滑架、钻杆组件、钻头组件和动力头，滑架下端悬挂两个相同的动力头，动力头包括动力源、箱体、传动齿轮组、变距机构和输出轴组件；变距机构可改变两动力头之间的距离，变距机构设有磁致伸缩位移传感器，可实时量测活塞杆相对于油缸的位移变化量，变距之后的两动力头输出轴组件的中心距离可锁定不变；箱体下端伸出的输出轴组件分别驱动钻杆组件的内杆和外杆正反旋转，内杆和外杆再分别驱动钻头组件的钻头双向旋转搅拌；采用本发明的间距可调两轴双向搅拌钻机及施工工法，双向搅拌桩中到中的间距能够灵活调节，并可大幅度提升高质量搅拌桩的施工效率。
