Offshore wind power straight pile guide frame fixing construction method and dismounting construction method
The invention provides an offshore wind power straight pile guide frame fixing construction method and a dismantling construction method, and belongs to the technical field of offshore wind turbine generator installation. The method is convenient and fast to construct and small in construction risk. According to the fixing construction method and the dismantling construction method, a guide framefoundation is arranged at the bottom of an adopted offshore wind power straight pile guide frame; during fixing construction, water is injected into a cavity of the guide frame foundation to form a gravity type foundation, the gravity type foundation is matched with a positioning pile to descend, the guide frame foundation sinks to the water bottom, a lower base of the guide frame foundation is inan annular column shape to sink into an underwater mud layer, and a fixing piece is inserted into an underwater bearing layer to achieve the fixing effect; and during dismantling construction, the guide frame foundation can ascend under the action of buoyancy by discharging ballast water in the cavity of the guide frame foundation, so that the fixing piece is pulled out of the underwater bearinglayer, and pulling of the positioning pile is completed.
本发明提出一种海上风电直桩导向架固定施工方法和拆除施工方法，属于海上风电机组安装技术领域，其施工方便快捷，施工风险小。该固定施工方法和拆除施工方法中，采用的海上风电直桩导向架的底部设有导向架基础；固定施工时，通过向导向架基础的空腔内注入水形成重力式基础，配合定位桩下降，使导向架基础下沉至水底，导向架基础的下基座呈环形柱状以陷入水下泥层中，固定件插入至水下持力层以起到固定作用；拆除施工时，通过排出导向架基础的空腔内的压载水，即可使导向架基础在浮力作用下上升，从而使固定件从水下持力层中拔出，完成定位桩拔除。
