Bidirectional stirring and bidirectional cutting single-shaft stirring drilling machine and construction method
The invention discloses a bi-directional stirring and bi-directional cutting single-shaft stirring drilling machine and a construction method, a stirring pile drilling machine is composed of a power head, a drill rod, stirring teeth, a stirring frame, an ordinary gear train turning driving device and a drill bit, and the inner stirring teeth are arranged on the drill rod; the outer stirring teeth are arranged on the stirring frame on the outer side of the drill rod; a forward rotation gear of the ordinary gear train turning driving device is fixed on the drill rod, and a reverse rotation gear of the ordinary gear train turning driving device is connected with the stirring frame; when the power head drives the drill rod to rotate, the forward and reverse rotation gear of the fixed shaft gear train turning driving device is driven to drive the inner and outer stirring teeth to do forward and reverse motion, and bidirectional cutting and bidirectional stirring are conducted on a soil layer in a drilled hole. The method has the technical characteristics of being green, environmentally friendly, safe and reliable, meanwhile, the pile forming quality of the single-shaft stirring pile and the stiff composite pile of the single-shaft stirring pile can be improved, the difficulty that the stirring pile is formed unevenly and cannot be formed in a muddy soil layer is eliminated, the construction efficiency is improved, and the method has great economic value and social benefits.
本专利公开了一种双向搅拌双向切割的单轴搅拌钻机与施工方法，搅拌桩钻机是由动力头、钻杆、搅拌齿、搅拌框架、定轴轮系变向驱动装置和钻头组成，内搅拌齿布置于钻杆上；外搅拌齿布置在钻杆外侧的搅拌框架上；定轴轮系变向驱动装置的正转齿轮固定在钻杆上，定轴轮系变向驱动装置的反转齿轮与搅拌框架相连；动力头带动钻杆转动时，驱动定轴轮系变向驱动装置的正反转齿轮带动内外搅拌齿呈正反向运动，对钻孔内土层作双向切割和双向搅拌。该专利具有绿色、环保和安全可靠的技术特征，同时能提高单轴搅拌桩及其劲性复合桩的搅拌桩成桩质量，消除了淤泥质土层中搅拌桩成桩不均匀、不成桩的困难，提高了施工效率，具有重大的经济价值和社会效益。
