Composite foundation pile supporting structure and composite foundation construction method
The invention discloses a composite foundation pile supporting structure and a composite foundation construction method, and belongs to the technical field of composite foundations. Comprising a lower pile cylinder and a driving mechanism, an anchor rod is hinged to the outer wall of the lower pile cylinder, the driving mechanism drives the anchor rod to rotate around a hinge shaft and stretch into foundation soil, and the other end of the anchor rod communicates with a grouting mechanism; the driving mechanism comprises a connecting piece arranged on the anchor rod, the connecting piece is matched with a driving clamping block in a clamping mode, the other end of the driving clamping block is hinged to one end of a driving arm, the other end of the driving arm is hinged to a driving sliding block, hinge shafts at the two ends of the driving arm are parallel to hinge shafts of the anchor rod, and the driving sliding block slides along a strip-shaped groove in the outer wall of the lower pile barrel. The driving arm is linked to extend through sliding of the driving sliding block, the driving arm drives the driving clamping block to rotate, and then the anchor rod is linked to rotate and extend into foundation soil. The grouting mechanism injects concrete grout into a gap between the anchor rod and foundation soil and a soil layer on the outer wall of the lower pile cylinder to form interacting concrete veins, and the soil strength is improved.
本发明公开了一种复合地基基桩支撑构造及复合地基施工方法，属于复合地基技术领域；包括下桩筒和驱动机构，下桩筒外壁铰接锚杆，驱动机构驱动锚杆绕铰接轴转动且伸入地基基土内，锚杆另一端与注浆机构连通；驱动机构包括设置在锚杆上的连接片，连接片与驱动卡接块卡接配合，驱动卡接块的另一端与驱动臂一端铰接，驱动臂的另一端与驱动滑块铰接，驱动臂两端的铰接轴与锚杆的铰接轴平行布置，驱动滑块沿下桩筒外壁上的条形凹槽滑动。通过驱动滑块的滑移连动驱动臂伸展，驱动臂带动驱动卡接块转动，进而连动锚杆旋转且伸入基土内。注浆机构将混凝土浆注入锚杆与基土的间隙，下桩筒外壁土层内形成相互作用的混凝土脉络，增加土壤强度。
