Large-diameter cast-in-situ bored pile head overall breaking system and construction method
The invention belongs to the technical field of cast-in-situ pile construction. A large-diameter cast-in-situ bored pile head overall breaking system comprises a pile head separation support, isolation sleeves, a first counter-force frame, a second counter-force frame and a driving part, wherein the first counter-force frame and the second counter-force frame are correspondingly arranged up and down; the multiple isolation sleeves are arranged on the pile head separation support, longitudinal main ribs on the upper portion of a steel reinforcement cage of a cast-in-situ pile are arranged in the isolation sleeves in a matched and penetrating manner, and the pile head separation support and the isolation sleeves are poured on the top of the cast-in-situ pile; and a plurality of first counter-force holes are circumferentially distributed in a pile head of the cast-in-situ pile, a plurality of second counter-force holes are circumferentially distributed in the position, on the lower portion of the pile head separation support, of the cast-in-situ pile, and the first counter-force frame and the second counter-force frame are correspondingly arranged in the first counter-force holes and the second counter-force holes correspondingly. The invention further discloses a large-diameter cast-in-situ bored pile construction method. The large-diameter cast-in-situ bored pile head overall breaking system is reasonable in overall design, the problem existing in breaking of the pile head of the large-diameter cast-in-situ bored pile in the prior art can be solved, the breaking efficiency is improved, and the structural damage to a pile body is reduced.
本发明属于灌注桩施工技术领域。一种大直径钻孔灌注桩桩头整体破除系统，包括桩头分离支架、隔离套管、上下对应设置的第一反力架和第二反力架和驱动部，多根隔离套管布设在桩头分离支架上，灌注桩的钢筋笼上部的纵向主筋匹配穿设在隔离套管内，桩头分离支架和隔离套管浇筑在灌注桩的顶部；在灌注桩的桩头上呈圆周布设有多个第一反力孔，在桩头分离支架下部的灌注桩上呈圆周布设有多个第二反力孔，第一反力架和第二反力架分别对应设置在所述第一反力孔和所述第二反力孔内。还公开了一种大直径钻孔灌注桩施工方法。本申请整体设计合理，能够解决现有技术中对大直径钻孔灌注桩的桩头的破除存在的难题，提高破除效率，降低对桩身的结构损害。
