Large-diameter rock-socketed single pile grouting bottoming implementation method
The invention belongs to the field of offshore wind power, and particularly relates to a large-diameter rock-socketed single pile grouting bottoming implementation method. The large-diameter rock-socketed single pile grouting bottoming implementation method comprises the steps that a plurality of grouting hard pipe units are sequentially screwed and fixed up and down, in the screwing operation process, a to-be-lengthened grouting hard pipe assembly is lifted through a lifting rope of a lifting mechanism, a to-be-assembled grouting hard pipe unit is lifted through a lifting rope of the other lifting mechanism, after one grouting hard pipe unit is connected to the grouting hard pipe assembly every time, the lifting rope connected with the grouting hard pipe assembly is removed and connected to the other to-be-assembled grouting hard pipe unit, then the other to-be-assembled grouting hard pipe unit is connected to the grouting hard pipe assembly in a screwed mode, and the operation is repeated till the grouting hard pipe assembly with the length meeting the requirement is assembled. In the construction process, the grouting hard pipe assembly can be installed only through the lifting mechanism, and a large crane is not needed, so that the cost is reduced, and the construction efficiency is improved.
本发明属于海上风电领域，具体涉及一种大直径嵌岩单桩灌浆打底实施方法，包括：将若干灌浆硬管单元依次上下螺接固定，在螺接操作过程中，通过一组吊装机构的吊绳吊住待加长的灌浆硬管组件，通过另一组吊装机构的吊绳吊住待组接的灌浆硬管单元，每次为灌浆硬管组件接上一根灌浆硬管单元后，将与灌浆硬管组件连接的吊绳卸下并连接到新的待组接灌浆硬管单元上，再将新的待组接灌浆硬管单元螺接到灌浆硬管组件上，如此反复操作，直至组接出长度符合要求的灌浆硬管组件。施工过程中仅需要采用吊装机构就可对灌浆硬管组件进行安装作业，无需使用的大型吊机，成本降低，施工效率提高。
