Carrier stiff composite pile and construction method
The invention discloses a carrier stiff composite pile. The carrier stiff composite pile comprises an outer pile body, an inner core pile and a carrier enlarged footing base, wherein the inner core pile is arranged on the inner side of the outer pile body, the lower end of the outer pile body and the carrier enlarged footing base are combined into a whole, and the outer pile body, the inner core pile and the carrier enlarged footing base are stressed together. According to the carrier stiff composite pile and a construction method, compared with a carrier pile, the carrier stiff composite pilehas the advantages of being high in bearing capacity and small in pile consumption, the technical problems that in the prior art, the bearing capacity of a pile foundation of a building is insufficient, the arrangement density of piles is large, and quality potential quality safety hazards exist are solved, a bulk material outer core is used for draining water, protecting walls and compacting soil between the piles, and the bearing capacity of a single pile can be effectively improved by utilizing the core pile with high rigidity and strength.
本发明公开了一种载体劲性复合桩，包括外桩身、内芯桩和载体扩大头底座，所述外桩身的内侧设置有内芯桩，且外桩身的下端与所述载体扩大头底座结合为一体，并且外桩身和内芯桩与载体扩大头底座共同受力。该载体劲性复合桩及施工方法，较于载体桩，载体劲性复合桩具有承载力强、用桩量少的优势，解决现有技术中建筑物的桩基承载力不足、桩的布设密度大和存在质量安全隐患等技术问题，利用散体材料外芯排水、护壁并挤密桩间土，而利用刚度和强度较大的芯桩可有效提高单桩承载力。
