Prefabricated tubular pile head core grouting construction method
The invention discloses a prefabricated pipe pile head core grouting construction method, and relates to the technical field of pipe pile core grouting construction, and the technical scheme is characterized in that a wood bottom plate is hung in a prefabricated pipe pile through an iron wire, a sandbag is placed on the wood bottom plate, the top end of the iron wire is fixed, and the sandbag is tamped; a reinforcement cage with a steel supporting plate at the bottom is arranged in the prefabricated pipe pile; and concrete is poured into the prefabricated pipe pile. The sandbag is high in plasticity and flexibility and can be well attached to the inner wall of the prefabricated pipe pile after tamping deformation, and the problem of slurry leakage possibly existing in concrete pouring is effectively solved. Meanwhile, the sand bag can isolate water at the bottom of the prefabricated pipe pile from the reinforcement cage, the corrosion risk of the reinforcement cage is effectively reduced, and the service life of the reinforcement cage in the prefabricated pipe pile in the embankment foot reinforcing project is prolonged.
本发明公开了一种预制管桩桩头灌芯施工方法，涉及管桩灌芯施工技术领域，其技术方案要点是通过铁丝在预制管桩内吊置一块木底板，在木底板上放置沙袋，固定铁丝顶端，对沙袋进行夯实；将底部具有钢托板的钢筋笼置于预制管桩内；向预制管桩内浇筑混凝土。本发明中沙袋可塑性强，柔韧度高，夯实形变后可很好的贴合预制管桩内壁，有效避免了混凝土浇筑可能存在的漏浆问题。同时，所述沙袋还能将预制管桩底部的水分与钢筋笼隔绝开来，有效降低钢筋笼腐蚀风险，提高了堤脚加固工程中预制管桩内钢筋笼的使用寿命。
