陡坡及基岩裸露地质条件下的稳桩工艺

Stabilizing of pile under condition of steep slope and bare bedrock

为解决码头陡坡裸岩区域的稳桩问题,开展了常规人工基床抛投以及导管架稳桩工艺的探索施工,根据不同地质影响解决了稳桩临时加固、导管架工艺的结构研究以及现场施工中的定位、提升、稳固、沉桩等技术问题,为同类型地质条件的稳桩工艺提供了参考依据。

To solve the problem of pile stabilization in the dock steep slope bare rock area,we carried out routine artificially flattened bed dumping,and the exploratory construction for the catheter frame pile stabilization process.We solved the technical problems such as pile stabilization temporary reinforcement,the construction study of catheter frame technology,and the positioning,ascension,solid,sinking of pile on site,according to different geologic conditions,and provided a referential basis for the pile stabilizing technology under the same kind geologic condition.
