摘要
以海宁市海月桥工程项目为例,介绍了桥梁冲击成孔灌注桩施工过程中溶洞的处理方法,对常规的冲击成孔灌注桩工艺的不足之处进行了分析,提出了一种回填黏土、块石的溶洞处理方法,以全面保证溶洞区域桥梁桩基的施工质量,以供参考。
Taking Haiyue Bridge project in Haining City as an example, this paper introduces the treatment method of karst cave in the construction process of bridge impact hole filling pile, and analyzes the shortcomings of the conventional impact hole filling pile technology, and puts forward a treatment method of backfilling clay and block stone into karst cave, so as to guarantee the construction quality of bridge pile foundation in karst cave area, for reference.
