摘要
介绍了京沪高速铁路南京大胜关长江大桥桩孔工程施工的主要工艺技术。根据工程的特点,选择主要施工设备、钻头和刀具的具体形式。根据施钻区域的工程地质条件和设备能力,具体选择钻压、转速等钻进工艺参数。并讨论了获得最佳进尺效率与工艺参数之间的关系。
The paper introduced the main technology of drilling construction for Dashengguan Changjiang brigde of Jing - Hu high-speed railway. Main construction equipments, concrete forms of drilling bits and cutting tools were selected according to the engineering characteristics; bit weight, rotating speed and other process parameters were selected according to the engineering geological conditions and equipment capacity. The relationship between optimum footage efficiency and process parameters was obtained by discussion.
