Ultra-long steel casing sinking system of large-diameter ultra-deep cast-in-place pile
The invention relates to the technical field of building foundation engineering, in particular to an ultra-long steel casing sinking system of a large-diameter ultra-deep cast-in-place pile. The system comprises a hydraulic vibration hammer, a crawler crane and a rotary drilling rig, the system further comprises an inner-layer steel casing body, a middle-layer steel casing body arranged outside the inner-layer steel casing body in a sleeving manner, an outer-layer steel casing body arranged outside the middle-layer steel casing body in a sleeving manner, a first fixing piece arranged between the outer-layer steel casing body and the middle-layer steel casing body, and a second fixing piece arranged between the middle-layer steel casing body and the outer-layer steel casing body, wherein the inner-layer steel casing body, the middle-layer steel casing body and the outer-layer steel casing body are coaxially arranged, the length of the middle-layer steel casing body is 23-30 m, the length of the outer-layer steel casing body is larger than that of the middle-layer steel casing body, the length of the outer-layer steel casing body is smaller than that of the middle-layer steel casingbody, the first fixing piece is used for fixing the outer-layer steel casing body and the middle-layer steel casing body, and the second fixing piece is used for fixing the middle-layer steel casing body and the inner-layer steel casing body. According to the ultra-long steel casing sinking system of the large-diameter ultra-deep cast-in-place pile, the ultra-long steel casing can overcome the side frictional resistance and sink into the ground.
本发明涉及建筑基础工程技术领域，具体涉及一种大直径超深灌注桩的超长钢护筒沉入系统，包括液压振动锤、履带吊机和旋挖钻机，其还包括内层钢护筒、套设于内层钢护筒外的中层钢护筒、套设于中层钢护筒外的外层钢护筒、设于外层钢护筒和中层钢护筒之间的第一固定件、设于中层钢护筒和外层钢护筒之间的第二固定件，所述内层钢护筒、中层钢护筒和外层钢护筒同轴设置，所述中层钢护筒的长度为23‑30m，所述外层钢护筒的长度大于中层钢护筒的长度，所述外层钢护筒的长度小于中层钢护筒的长度，所述第一固定件用于固定外层钢护筒和中层钢护筒，所述第二固定件用于固定中层钢护筒和内层钢护筒。本发明使超长钢护筒能克服侧摩擦阻力沉入地面以下。
