Drilling guide frame and construction method
The invention discloses a drilling guide frame and a construction method, and relates to the technical field of offshore wind power jacket foundation construction. According to the drilling and guiding frame, the drilling and guiding frame can be stably in place and leveled on the seabed through penetration of the suction bucket, and the drilling and guiding frame can be separated from the seabed soil through jacking of the suction bucket, so that preparation is made for subsequent hoisting. The lifting points are arranged on the lower module, the lifting ropes penetrate through holes in the top deck to be connected with the main hook of the floating crane, the number of supporting rod pieces of the upper module is reduced, the structure of the guide frame is optimized, the structural weight is reduced, and the drilling and guiding frame which is light and easy to install is achieved.
本发明公开了一种打钻打导向架及施工方法，涉及海上风电导管架基础施工技术领域。本发明的打钻打导向架通过吸力桶的贯入，实现打钻打导向架的在海床上稳固就位和调平，通过吸力桶的顶升，实现打钻打导向架的和海床土壤脱离，为后续吊起做准备。通过吊点设置在下部模块，吊绳穿顶层甲板开孔连接浮吊主钩，减少上部模块支撑杆件数量，优化导向架结构，减轻结构重量，实现了轻量化且易于安装的打钻打导向架。
