Construction process of pile-first-method sleeving type jacket of offshore wind power booster station
The invention discloses a construction process of a pile-first-method sleeving type jacket of an offshore wind power booster station. The construction process comprises the following steps of positioning a pile stabilizing construction platform, inserting and driving auxiliary piles, fixing the pile stabilizing construction platform, sinking steel pipe piles, carrying out steel pipe pile rock-socketed construction, dismounting the pile stabilizing construction platform, mounting the jacket, carrying out jacket grouting, carrying out foundation anti-scouring protection and connecting a boosterstation platform and the jacket, when the pile stabilizing construction platform is positioned, the pile stabilizing construction platform and the auxiliary piles are transported to a construction site through a transport barge, the pile stabilizing construction platform passes through the barge to a platform positioning ship to be leveled, when the auxiliary piles are inserted and driven, a craneship is matched with a vibratory hammer for construction, when the pile stabilizing construction platform is fixed, the pile stabilizing construction platform and the four auxiliary piles are temporarily welded and fixed, and when the jacket is mounted, a cross-shaped portal frame arranged at the top of each pile leg sleeve in advance is placed at the top of the corresponding steel pipe pile. According to the construction process, the construction efficiency can be effectively improved, the construction quality is ensured, and the offshore construction period is shortened.
本发明公开了一种海上风电升压站先桩法外套式导管架的施工工艺，包括以下步骤：稳桩施工平台定位、辅助桩插打、稳桩施工平台固定、钢管桩沉桩、钢管桩嵌岩施工、稳桩施工平台拆除、导管架安装、导管架灌浆、基础防冲刷保护和升压站平台与导管架连接。进行稳桩施工平台定位步骤时，采用运输驳将稳桩施工平台和辅助桩运输至施工现场并过驳至平台定位船调平；进行辅助桩插打步骤时，通过起重船配合振动锤进行施工；进行稳桩施工平台固定步骤时，稳桩施工平台与四根辅助桩进行临时焊接固定；进行导管架安装步骤时，每条桩腿套管的顶部预先设置的十字形门架搁置在对应的钢管桩的顶部。本发明能有效的提高施工功效，确保施工质量，节省海上施工周期。
