Construction method of high-speed deepwater bare rock geology high pile cap in mountainous area
The invention discloses a mountainous area high-speed deepwater bare rock geological high pile cap construction method, which is characterized in that in a non-bank slope river channel area such as a riverbed bare area with deeper water depth and harder rocks or a large-particle-size pebble covering layer, a steel casing is inserted and driven to assist a percussion drill to lead a hole to form a pile, so that the stability of a pile foundation in deepwater and bare rock environments is ensured; the pile foundation is smoothly and safely holed to lift the bearing platform to be above the water level, meanwhile, high construction measure cost and safety cost generated by underwater construction of the straining beam are avoided, the construction difficulty is greatly reduced, the construction safety is improved, and the method has the advantages of being safe, economical and environmentally friendly, obvious in economic, progress and social benefits and good in application and popularization value.
本发明公开了一种山区高速深水裸岩地质高桩承台施工方法，在水深较深、岩质较为坚硬的河床裸露区域或大粒径卵石覆盖层等的非岸坡河道区域内，采用插打钢护筒辅助冲击钻引孔成桩确保了桩基在深水、裸岩环境下的稳定性，使桩基顺利安全成孔将承台提升到水位以上，同时避免了水下施工系梁产生的高昂施工措施费、安全费，大大降低了施工难度，提高了施工安全性，具有安全、经济、环保的特点，经济、进度和社会效益明显，具有较好的推广应用价值。
