Steel pipe pile construction method under reservoir area deepwater abrupt slope bare rock geological condition
The invention discloses a steel pipe pile construction method under reservoir area deepwater abrupt slope bare rock geological conditions, which is characterized in that the steel pipe pile is preliminarily positioned and hit through a vibratory hammer, so that the bottom opening of the steel pipe pile is stable, and a fully weathered geological rock stratum with the bottom incapable of being liquefied is replaced with an impact hammer for hit follow-up until the designed sinking elevation is reached. The problems of driving depth and perpendicularity of the steel pipe pile under special geological conditions can be effectively solved, driving efficiency is improved, sinking quality of the steel pipe pile is guaranteed, and construction safety is guaranteed.
本发明公开了一种库区深水陡坡裸岩地质条件下钢管桩施工方法，其特征在于，通过振动锤对钢管桩进行初步定位及施打，使钢管桩底口稳固，对于底部无法液化的全风化地质岩层更换成冲击锤进行施打跟进，直至达到设计下沉标高。本发明能有效解决特殊地质条件下钢管桩打入深度及垂直度的问题，提高施打效率，保证钢管桩下沉质量，确保施工安全。
