Steel pipe pile guide hole construction method under deepwater bare rock geological condition
The invention discloses a steel pipe pile guide hole construction method under a deepwater bare rock geological condition, which is applied to the technical field of deepwater engineering construction, and mainly comprises the following steps: S0, modeling by adopting finite element software, and carrying out construction safety verification; s1, the small-size steel pipe is positioned and installed firstly, and then preliminary fixing is conducted in the mode that the small-size steel pipe is sleeved with the steel pipe pile; s2, the steel pipe piles are vibrated and fixed, hole guiding is conducted on the steel pipe piles towards the deep water bed bottom, and then vibration fixing is conducted; s3, performing a tensile test on two adjacent steel pipe piles to obtain a horizontal load-displacement curve of the steel pipe piles and ensure the horizontal load resistance of the steel pipe piles when the hole guiding effect needs to be checked; according to the method, steel pipe pile hole guiding can be efficiently achieved, the steel pipe pile inserting and driving difficulty is reduced, installation is stable, and a series of problems of complicated construction procedures, long construction period, serious environmental pollution, high cost and the like of a traditional construction technology are effectively solved.
本发明公开了深水裸岩地质条件下钢管桩引孔施工方法，应用于深水工程施工技术领域，该方法主要包括：S0、采用有限元软件建模，并进行施工安全性验证；S1、先定位安装小尺寸钢管，再以钢管桩套在小尺寸钢管外的方式初步固定；S2、对钢管桩进行振捣固定，先在钢管桩内向深水床底进行引孔，再振捣固定；在需检查引孔效果时进行S3、对相邻两根钢管桩进行抗拉试验，得到钢管桩的水平荷载‑位移曲线，确保钢管桩的抗水平荷载能力；该方法能够高效实现钢管桩引孔，降低钢管桩插打难度，安装稳固，有效解决了传统施工工艺存在施工工序繁杂、施工工期长、环境污染大、成本高等一系列问题。
