钻孔灌注桩施工技术在公路桥梁工程中的应用

Application of Bored Pile Construction Technology in Highway Bridge Engineering

依托公路桥梁工程实例,通过对深水区钻孔灌注桩施工难点的分析,提出相应的处理措施;对具体施工技术进行研究,并考虑施工现场溶洞的特殊性,提出抛填法、灌注混凝土填充法两种处理方法,有效改善现场地质条件,建设稳定可靠的钻孔灌注桩,以便公路桥梁的有效建设和安全使用。

Relying on the example ofhighway bridge engineering,through the analysis of the construction difficulties ofbored pile in deep water area,the solution is proposed,the specific construction technology is studied,and considering the particularity of the karst cave in the construction site,two treatment methods ofjet-fll method and poured concrete flling method are proposed,which can effectively improve the geological conditions ofthesite and build stable and reliable bored pile.Forthe effective construction and safe use ofhighway bridges.
