High-strength building foundation pile construction method
The invention belongs to the technical field of building engineering, and particularly relates to a high-strength building foundation pile construction method which comprises the steps of manufacturing a reinforcement cage, lowering a guide pipe, lowering the reinforcement cage, pouring concrete, lifting the guide pipe and placing a bearing component in place. A grading experiment of concrete is carried out according to designed strength requirements, the maximum particle size of aggregate in the concrete is determined, then a steel reinforcement framework is manufactured according to data of the maximum particle size of the aggregate, then bearing components are sequentially installed in the steel reinforcement framework, and then the concrete is poured into a foundation pile hole through a guide pipe. Due to the fact that the bearing component is arranged in the steel reinforcement framework, large aggregates with large specific gravity can be borne by the bearing component when moving downwards in the pouring process and the vibrating process, the large aggregates on the upper portion are prevented from moving downwards, the problem that the strength of the upper portion of the pile body is low can be avoided, and the service life of the pile body is prolonged. And the overall bearing capacity of the foundation pile can be improved.
本发明属于建筑工程技术领域，具体的说是一种高强度建筑基桩施工方法，包括钢筋笼制作、下放导管、下放钢筋笼、灌注混凝土、提升导管和承托部件就位；本发明中通过设计的强度要求进行混凝土的级配实验，确定混凝土中的骨料的最大粒径，随后根据最大的骨料的粒径数据，制作出钢筋骨架，随后依次承托部件安装到钢筋骨架中，随后通过导管向基桩孔内部浇筑混凝土，由于在钢筋骨架内部设置有承托部件，进而使得在灌注的过程中和振捣的过程中，比重较大的大骨料在向下移动时，会被承托部件承托住，进而避免上部的大骨料向下移动，进而能够避免造成桩体的上部强度低的问题，进而能够提高基桩的整体承载能力。
