摘要
钻孔灌注桩目前在公路桥梁和城市建设中应用极为普遍,也非常具有施工优势。地下水较为丰富、地质坚硬且复杂的地段都会优先采用机械钻孔桩工艺进行桩基施工。钻孔灌注桩属于隐蔽工程,成桩过程比较复杂,施工难度较大,施工过程中容易出现各种问题,施工期间应进行严格管控,才能有效地保证桩基施工质量。因此,本文主要分析了钻孔灌注桩的施工工艺、施工要点、常见问题及处理措施。
Bored piles are currently widely used in highway bridges and urban construction, and they also have construction advantages. Where groundwater is rich, and the geology is hard and complex, mechanical pile drilling is preferred for pile foundation construction. Bored cast-in-situ piles are hidden projects, the pile forming process is relatively complicated, and the construction is difficult, and various problems are prone to occur during the construction process, strict management and control should be performed during construction to effectively ensure the quality of pile foundation construction. Therefore, this paper mainly analyzed the construction technology, construction points,common problems and treatment measures of bored piles.
