Precast beam pedestal miniature steel pipe pile compression-resistant foundation and construction method thereof
The invention discloses a precast beam pedestal miniature steel pipe pile compression-resistant foundation which comprises a precast beam pedestal and a plurality of miniature steel pipe piles, each miniature steel pipe pile comprises a steel pipe, a steel bar and a plurality of positioning ribs, the positioning ribs are welded and fixed to the side portion of the steel pipe, the steel bar is welded and fixed to the bottom of the steel pipe, and the positioning ribs are welded and fixed to the bottom of the steel pipe. The precast beam pedestal is provided with a plurality of holes for the miniature steel pipe piles to be inserted, and the positioning ribs are provided with protruding parts matched with the hole walls. The steel pipes, the reinforcing steel bars and the positioning ribs are matched for installation, the bearing capacity of the miniature steel pipe pile compression-resistant foundation of the precast beam pedestal and the bearing capacity of the foundation are improved, differential settlement of the foundation of the precast beam pedestal is prevented, the quality risk of follow-up precast beam construction is reduced, construction operation under the condition of narrow construction space is met, and the construction period is shortened. The construction time of the precast beam pedestal is shortened, the follow-up precast beam construction progress is accelerated, and the effects of improving the foundation bearing capacity and preventing the foundation settlement of the precast beam pedestal are achieved.
本发明公开了一种预制梁台座微型钢管桩抗压基础，包括预制梁台座、若干个微型钢管桩，每一所述微型钢管桩包括钢管、钢筋、若干根定位筋，所述定位筋焊接固定于所述钢管的侧部，所述钢筋焊接固定于所述钢管的底部，所述预制梁台座设有若干个用于微型钢管桩插入的孔，所述定位筋设置有与孔壁配合的凸起部。采用钢管、钢筋、若干根定位筋的配合进行安装，实现了预制梁台座微型钢管桩抗压基础地基及基础承载力的提高，防止预制梁台座基础的不均匀沉降，降低了后续预制梁施工的质量风险，满足施工空间狭小条件下的施工作业，加快了预制梁台座建设时间，提高了后续预制梁施工进度，达到提高地基承载力以及防止预制梁台座基础沉降的效果。
