Foundation engineering composite pile and pile foundation construction method
The invention provides a foundation engineering composite pile and a pile foundation construction method. The foundation engineering composite pile comprises a pile body, a center steel rod and a hexagonal operating rod, a center groove is formed in the center of the top of the pile body, and the center steel rod is movably arranged in the center groove. The foundation engineering composite pile and the pile foundation construction method are reasonable in design; a plurality of telescopic transverse reinforcing devices are arranged on the pile body, when the center steel rod is rotated, the center steel rod can drive a power screw to rotate through cooperation of a driving bevel gear and a transmission bevel gear, the power screw pushes a movable bearing and a spiral drill bit to move towards the outside of a convex telescopic hole through a movable screw pipe, and meanwhile, the power screw drives the spiral drill bit to rotate through cooperation of a second limiting sliding block and a second limiting sliding groove, so that the spiral drill bit is gradually drilled into soil around the pile body in a rotating mode, the effective reinforcing effect can be achieved, the compactness of the surrounding soil can be improved, and the installation quality of the composite pile is further improved.
本发明提供一种地基工程组合桩及桩基施工方法，包括桩体、中心钢杆和六角操作杆，所述桩体顶部的中心位置处开设有中心槽，所述中心钢杆活动安装在中心槽内，该地基工程组合桩及桩基施工方法设计合理，桩体上安装了若干个能够伸缩的横向加固装置，在转动中心钢杆时，中心钢杆能够通过主动斜齿轮与传动斜齿轮配合带动动力螺杆转动，动力螺杆通过活动螺管推动活动轴承和螺旋钻头向凸型伸缩孔外移动，同时，动力螺杆通过限位滑块二与限位滑槽二配合带动螺旋钻头转动，从而使螺旋钻头旋转渐进的钻入桩体四周的土壤中，能够起到有效的加固效果，并且能够增加周围土壤的紧实度，进一步提高组合桩安装的质量。
