Single-shaft deep mixing pile drilling tool with inner-layer and outer-layer mixing teeth
The invention discloses a single-shaft deep mixing pile drilling tool with inner-layer and outer-layer mixing teeth. A drill rod of the single-shaft deep mixing pile drilling tool is of a double-layer structure, a mixing shaft and a drill bit are arranged at the lower end of the inner-layer drill rod, and the outer-layer drill rod is connected with a mixing cover; the outer-layer mixing teeth are arranged on the cylindrical hollowed-out mixing cover, and the inner-layer mixing teeth are arranged on the hollow mixing shaft; the inner-layer and outer-layer mixing teeth are arranged in a staggered mode in space and engaged with each other; the mixing cover covers the inner-layer mixing shaft; and a top slurry spraying opening is formed in the upper portion of the mixing shaft, and a bottom slurry spraying opening is formed in the drill bit. Rock-soil particles are efficiently broken and fully mixed with soil hardening agent slurry to form fluid hardened soil. The single-shaft deep mixing pile drilling tool has the social benefits of being environmentally friendly, safe and reliable, meanwhile, the manufacturing cost can be reduced, the construction period can be shortened, and great economic value is achieved.
本发明公开了一种具有内外双层搅拌齿的单轴深搅桩钻具，其钻杆是双层结构，内层钻杆的下端设置有搅拌轴和钻头，外层钻杆与搅拌罩相连；外层搅拌齿布置在一个园柱状镂空搅拌罩上，内层搅拌齿布置在中空的搅拌轴上；内外双层搅拌齿在空间上内呈相互错位布置并相互咬合；搅拌罩罩住内层的搅拌轴；在搅拌轴的上部布置一个顶喷浆口，在钻头处布置一个底喷浆口。通过高效破碎岩土颗粒并与土体硬化剂浆液充分的搅拌混合形成流态的硬化土。该专利具有绿色、环保和安全可靠的社会效益，同时能降，低造价和缩短工期，具有重大的经济价值。
