The invention discloses a construction method for a reinforcement cage of a cast-in-situ bored pile, which comprises the following steps: marking a hole-forming position in a foundation pit, and obtaining a first reference hole-forming diameter and a second reference hole-forming diameter according to the diameter of the reinforcement cage; forming an orifice section of the cast-in-situ bored pile according to the first reference pore-forming diameter; forming a hole body section of the cast-in-situ bored pile according to the second reference hole forming diameter; the steel reinforcement cage is placed in the hole body section, and a cast-in-place limiting piece is constructed and formed in the hole opening section so that the cast-in-place limiting piece can be connected with the end of the steel reinforcement cage; and concrete is poured into the cast-in-situ bored pile, and construction of the cast-in-situ bored pile is completed. The steel bars are planted on the inner side wall of the hole opening section, the pile casing in the hole body section is utilized, and the cast-in-place concrete is poured between the pile casing and the inner side wall of the hole opening section, so that the cast-in-place limiting piece is formed, a reinforcement cage located in the cast-in-situ bored pile is prevented from floating upwards, and the forming quality of the cast-in-situ bored pile is improved; and the construction quality and the construction efficiency of the cast-in-situ bored pile are improved.
本发明公开了一种钻孔灌注桩的钢筋笼施工方法，包括：标记基坑中的成孔位，并根据钢筋笼的直径，获得第一参照成孔直径和第二参照成孔直径；根据所述第一参照成孔直径形成钻孔灌注桩的孔口段；根据所述第二参照成孔直径形成所述钻孔灌注桩的孔身段；向孔身段内放置所述钢筋笼，在所述孔口段施作形成现浇限位件，以使所述现浇限位件与所述钢筋笼的端头连接；向所述钻孔灌注桩内灌注混凝土，完成钻孔灌注桩的施工。本发明通过在孔口段的内侧壁进行植筋，并利用孔身段中的护筒，在护筒与孔口段的内侧壁之间浇筑现浇混凝土，以形成现浇限位件，避免在位于钻孔灌注桩中的钢筋笼上浮，提升钻孔灌注桩的成型质量，提升钻孔灌注桩的施工质量和施工效率。
