Open sea overwater gravel pile construction method
The invention discloses an open sea overwater gravel pile construction method, and relates to the technical field of overwater foundation treatment. The open sea overwater gravel pile construction method provided by the invention comprises the following steps: surveying and lofting: carrying out pile arrangement and lofting on gravel pile hole sites according to a preset drawing; a gravel pile ship is arranged in place, specifically, the gravel pile ship is arranged in place according to the construction area and the survey lofting result, and the posture and anchoring are adjusted; pipe sinking is conducted, specifically, the pile pipe with the valve steel pile shoe arranged at the lower end is driven into the underwater foundation downwards through a vibratory hammer, and the vibratory hammer is stopped after the designed elevation is reached; the pile pipe is filled with gravel filler, and the gravel filler is vibrated to the elevation; and vibration pipe pulling: starting a vibration hammer, and uniformly pulling out the pile pipe towards the top while vibrating. According to the open sea overwater gravel pile construction method, the gravel pile position arrangement and the construction process are optimized, so that the gravel pile construction process is suitable for open sea water areas, and the construction quality is guaranteed.
本发明公开了一种外海水上碎石桩施工方法，涉及水上地基处理技术领域。本发明所提供的外海水上碎石桩施工方法，包括：测量放样：根据预设图纸，对碎石桩孔位进行布桩放样；碎石桩船就位：根据施工区域和测量放样结果，将碎石桩船布置就位，并调整姿态和锚固；沉管：利用振动锤，将下端设有活瓣钢桩靴的桩管向下打入水下地基，并在达到设计高程后停锤；加料：向桩管内填充碎石填料，并振沉至标高；振动拔管：启动振动锤，振动的同时向顶部均匀拔出桩管。本发明所提供的外海水上碎石桩施工方法，通过优化碎石桩桩位布置和施工流程，使碎石桩施工工艺适用于外海水域，保障了施工质量。
