Multi-layer mutual-shearing stirring drilling machine capable of transversely stretching and reducing and construction method of multi-layer mutual-shearing stirring drilling machine
The invention provides a multilayer mutual shearing stirring drilling machine capable of transversely stretching and reducing and a construction method thereof, relates to the technical field of stirring drilling machines, and aims to solve the problem of reducing pile foundations of soft foundations. The stirring drilling machine comprises a drill rod assembly and a drill bit assembly. The drill rod assembly comprises an outer drill rod and an inner drill rod, the inner drill rod is sleeved with the outer drill rod, and the outer drill rod and the inner drill rod can independently rotate around the same axis. The drill bit assembly comprises an outer stirring frame and a stirring wing assembly; one end of the outer stirring frame is connected with the outer drill rod, the other end of the outer stirring frame is connected with the inner drill rod, and the outer stirring frame can stretch out and draw back in the radial direction of the drill rod; the outer stirring frame rotates along with the outer drill rod; the stirring wing assemblies are fixedly arranged on the outer stirring frame and the inner drill rod correspondingly, and stirring wings on the stirring wing assemblies can stretch out and draw back in the radial direction of the drill rod. According to the scheme, the material consumption is reduced, the construction period is shortened, meanwhile, the uniformity and the pile body strength of the two-way stirring pile can be greatly improved, and the construction quality is comprehensively improved.
本发明提供一种可横向伸缩变径的多层互剪搅拌钻机及其施工方法，涉及搅拌钻机技术领域，为解决软弱地基变径桩基的问题而发明。所述搅拌钻机包括钻杆组件和钻头组件；钻杆组件包括外钻杆和内钻杆，外钻杆套设在内钻杆外，并且外钻杆和内钻杆能够绕相同的轴线进行独立转动；钻头组件包括外搅拌框和搅拌翼组件；外搅拌框的一端与外钻杆连接，搅拌框的另一端与内钻杆连接，并且外搅拌框能够沿钻杆的径向进行伸缩；外搅拌框随外钻杆一起转动；搅拌翼组件分别固定设置于外搅拌框和内钻杆上，并且搅拌翼组件上的搅拌翼能够沿钻杆的径向进行伸缩；本发明提供的方案，在降低材料消耗和节省工期的同时，能够大幅度提升双向搅拌桩的均匀性和桩身强度，全面改善施工质量。
