Anti-pulling hollow pile and construction method thereof
The invention relates to an anti-pulling hollow pile and a construction method thereof. The anti-pulling hollow pile comprises an outer reinforcement cage and a hollow pile body, wherein the outer reinforcement cage and the hollow pile body are integrally formed through concrete pouring, a supporting object, an inner reinforcement cage and a concrete injection core are arranged in the hollow pile body, and the concrete injection core is located on the supporting object; the inner reinforcement cage and the concrete injection core are integrally formed, a protrusion is arranged in the hollow pile body, one side of the protrusion and the hollow pile body are integrally formed through concrete pouring, and the other side of the protrusion and the concrete injection core are integrally formed; the construction method comprises steps that in the hollow pile manufacturing stage, the hollow pile body is obtained by pouring concrete, and one side of the protrusion is exposed out of the concrete of the hollow pile body; a pile sinking stage is conducted; a core grouting stage is conducted, specifically, the supporting object is placed in the hollow pile body, the inner reinforcement cage is placed on the supporting object, concrete is poured into the hollow pile body, and a concrete injection core is obtained. The anti-pulling hollow pile is advantaged in that the defect of potential safety hazards existing in the anti-pulling hollow pile is overcome.
本申请涉及一种抗拔空心桩及其施工方法，一种抗拔空心桩包括外钢筋笼和空心桩本体，外钢筋笼通过混凝土浇筑与空心桩本体一体成型，空心桩本体内设有支撑物、内钢筋笼和混凝土注芯，混凝土注芯位于支撑物上，内钢筋笼与混凝土注芯一体成型，空心桩本体内设有凸起物，凸起物的一侧通过混凝土浇筑与空心桩本体一体成型，凸起物的另一侧与混凝土注芯一体成型；其施工方法为：空心桩制作阶段：通过浇筑混凝土得到空心桩本体，使凸起物的一侧暴露于空心桩本体的混凝土外；沉桩阶段；灌芯阶段：将支撑物放入空心桩本体内，将内钢筋笼放置于支撑物上，向空心桩本体内灌注混凝土，得到混凝土注芯。本申请具有改善抗拔空心桩存在安全隐患的缺陷的效果。
