Offshore wind power barrel type foundation and air bag grouting construction method
The invention belongs to the technical field of offshore wind power foundations, and discloses an offshore wind power barrel type foundation and an air bag grouting construction method. According to the offshore wind power barrel type foundation and the air bag grouting construction method, a top plate of the barrel type foundation is connected with a grouting channel, a grout returning channel and a ventilation/water channel in a sealed mode; a filling air bag connected with the grouting channel and the grout returning channel is arranged in the barrel-shaped foundation and used for conducting grouting through the grouting channel and the grout returning channel after the barrel-shaped foundation sinks to the limiting position under negative pressure; the ventilation/water channel communicates with the space between the barrel-shaped foundation and the filling air bag, and the ventilation/water channel is used for pressurizing the interior of the barrel-shaped foundation to achieve floating of the barrel-shaped foundation when the barrel-shaped foundation is recycled; and the filling air bag discharges filler and is recycled together with the barrel-shaped foundation or disconnected to be discarded on site. According to the offshore wind power barrel type foundation and the air bag grouting construction method, engineering investment can be effectively reduced, after the barrel type foundation is put into use, stress distribution is reasonable, the bearing capacity is high, and the structural stability is improved; more importantly, the barrel type foundation can be smoothly recycled, the recycling cost is greatly reduced, and sustainable development of offshore wind power is promoted.
本发明属于海上风电基础技术领域，公开了一种海上风电筒型基础和气囊灌浆施工方法，筒型基础的顶板密封连接有灌浆通道、返浆通道、通气/水通道；筒型基础内部设置有与灌浆通道、返浆通道连接的填充气囊，填充气囊用于在筒型基础负压下沉到极限位置后，通过灌浆通道和返浆通道进行灌浆；通气/水通道与筒型基础和填充气囊之间的空间相连通，通气/水通道用于在筒型基础回收时对筒型基础内部增压实现筒型基础上浮；而填充气囊排出填充物与筒型基础一同回收或者断开连接在现场丢弃。本发明能有效减少工程投入，且筒型基础投入使用后应力分布合理，承载能力强，结构稳定性提高；更重要的是能够使筒型基础顺利回收，大幅降低回收成本，促进海上风电的可持续发展。
