Offshore wind power steel pipe pile combined reinforcing device and method
The invention discloses an offshore wind power steel pipe pile combined reinforcing device and method, and belongs to the technical field of offshore foundation reinforcement. The device comprises a steel pipe pile, a plurality of grouting pipes and a plurality of cement soil mixing piles, wherein the grouting pipes are vertically arranged along the inner side wall of the steel pipe pile, slurry outlets in the bottoms of the grouting pipes penetrate through the side wall of the steel pipe pile and communicate with the outer side of the steel pipe pile, the multiple cement soil mixing piles are vertically arranged on the outer side of the steel pipe pile. According to the device, the grouting pipe structure is arranged to achieve pile side grouting and is matched with deep combined reinforcement of the cement-soil mixing piles, on one hand, pile side friction resistance can be improved, the vertical bearing capacity of a pile foundation can be improved, vertical settlement can be reduced, on the other hand, the deep mixing piles can improve shallow soil body characteristics, the horizontal bearing capacity of the pile foundation can be improved, horizontal displacement can be reduced, through cooperation with the offshore wind power steel pipe pile combined reinforcing device, the horizontal and vertical bearing capacity of a pile foundation is effectively improved, the cost of an offshore wind power project is reduced, and safety and stability of a fan structure are ensured.
本发明公开了一种海上风电钢管桩联合加固装置及加固方法，属于海上基础地基加固技术领域。装置包括钢管桩；还包括：注浆管，其有若干个，均沿着钢管桩内侧壁竖直布置，所述注浆管底部出浆口贯穿钢管桩侧壁并连通至钢管桩外侧；水泥土搅拌桩，其有若干个，均竖直布置于钢管桩外侧。本发明设置注浆管结构以实现桩侧注浆，配合水泥土搅拌桩深层联合加固，一方面能提高桩侧摩擦阻力，提高桩基竖向承载力，减少竖向沉降，另一方面深层搅拌桩能够改善浅层土体特征，提高桩基水平承载力，减小水平变位，配合本发明的海上风电钢管桩联合加固装置，有效地提高桩基水平和竖向承载能力，降低海上风电工程成本，确保风机结构的安全和稳定。
