An uplift tubular pile belongs to the technical field of constructional engineering and comprises an outer pile, a middle pile and an inner pile, the outer pile and the inner pile are precast piles, the middle pile is a cast-in-place pile, a plurality of through holes are formed in the wall of the outer pile, each through hole is in a turning shape with the middle lower than the two ends, and the outer diameter of the inner pile is smaller than the inner diameter of the outer pile; the inner pile is installed in the center of the outer pile, a gap between the outer wall of the inner pile and the inner wall of the outer pile is the position of a cast-in-place pile of the middle pile, and the cast-in-place pile is not provided with a steel bar keel but is directly filled with concrete mortar. Concrete mortar is poured through a high-pressure grouting pump, and after a gap between an outer pile and an inner pile is filled with the concrete mortar, the concrete mortar is further poured into a through hole, extruded towards a soil body on the periphery of an outer opening of the outer pile through the through hole, diffused towards the soil body on the periphery of the outer opening and permeated into the concrete mortar, and concrete miscellaneous blocks are formed; the concrete miscellaneous block can be connected with the pipe pile and the surrounding soil body after being coagulated and stabilized, and the pulling-resistant and compression-resistant effects of the pipe pile can be greatly improved.
一种抗拔管桩，属于建筑工程技术领域，包括外桩、中桩和内桩，所述外桩和内桩为预制桩，所述中桩为现浇桩，所述外桩壁上设有若干个通孔，所述通孔为中部低两端高的转折状，所述内桩的外径小于外桩的内径；所述内桩安装在外桩的中心，所述内桩外壁与外桩内壁之间的空隙为中桩的现浇桩位置，所述现浇桩不设置钢筋龙骨，而是直接灌注混凝土砂浆；其采用高压注浆泵灌注混凝土砂浆，并使混凝土砂浆在填充外桩与内桩之间的空隙后，还灌注在通孔内并经通孔向外桩的外口周边的土体挤压，并向外口周边的土体扩散和渗透混凝土砂浆，构成混凝土杂块，该混凝土杂块在凝结稳定后可连结管桩和周边土体，可大大提高管桩的抗拔和抗压效果。
