Multi-layer mutual shearing mixing pile construction equipment and construction method
The invention relates to a multi-layer mutual shear mixing pile construction device and a construction method.The multi-layer mutual shear mixing pile construction device comprises a drilling machine main body, a slurrying background, a grouting pump, a first driving unit and a second driving unit, motor power heads or hydraulic motor power heads are adopted in the first driving unit and the second driving unit, the first driving unit and the second driving unit are horizontally and symmetrically distributed in a box body, and a drill rod comprises an inner rod and an outer rod; an inner rod in the drill rod is powered by the first driving unit through the speed-changing gear box, and an outer rod in the drill rod is powered by the second driving unit through the speed-changing gear box; the upper end of a grouting channel arranged in the inner rod is communicated with the faucet, and the lower end of the grouting channel is communicated with a slurry spraying opening formed in the bottom end of the drilling tool. The overall safety of the construction equipment can be improved, output power is guaranteed through double-power output, adaptive adjustment of the rotation speed ratio of the inner drill rod and the outer drill rod can be achieved, the slurry spreading uniformity is improved through the stirring drill bit and the slurry spraying mode, and the pile forming quality of a stirring pile can be greatly improved through the construction equipment.
本发明涉及一种多层互剪搅拌桩施工装备及施工方法，包括钻机主体、制浆后台、注浆泵，第一驱动单元和第二驱动单元均采用电机动力头或液压马达动力头，且第一驱动单元和第二驱动单元呈水平对称分布在箱体内，钻杆包括内杆和外杆，且钻杆中的内杆通过齿轮变速箱由第一驱动单元提供动力，钻杆中的外杆通过齿轮变速箱由第二驱动单元提供动力；内杆内部所设有的注浆通道的上端与水龙头连通，注浆通道的下端与钻具底端所设有的喷浆口连通；本发明可以提高施工装备的整体安全性，采用双动力输出保证了输出动力，并可实现内外钻杆转速比适应性调整，且通过搅拌钻头及喷浆方式提高浆液撒布均匀性，该施工装备可大幅度提高搅拌桩的成桩质量。
