Rapid grouting type foundation structure combining offshore wind plant and pile foundation construction
The invention relates to the technical field of offshore wind power buildings, in particular to an offshore wind power plant and pile foundation construction combined rapid grouting type foundation structure which comprises a steel pipe pile, a grouting guide pipe, a grouting protruding branch pipe and a flap valve, and the top of the steel pipe pile is connected with a wind turbine generator tower; the grouting guide pipe is arranged on the inner side of the steel pipe pile, and the grouting protruding branch pipe is arranged on the outer side of the steel pipe pile. Through holes are formed in the peripheral side of the steel pipe pile, the grouting protruding branch pipe communicates with the grouting guide pipe through the through holes, and the flap valve is arranged on the inner side of a pipe opening of the grouting protruding branch pipe. Slurry is injected into the grouting guide pipe and emerges from a pipe opening of the grouting protruding branch pipe, and a high-pressure grouting reinforcing body is formed on the peripheral side of the steel pipe pile. On the premise of meeting the functional requirements and self strength of a pile foundation body, large-diameter single pile construction and foundation treatment are fused, the purposes of rapidly reinforcing soil around the pile and reducing horizontal displacement of a supporting structure can be achieved, the manufacturing cost can be reduced, and the construction period can be shortened.
本发明涉及海上风电建筑技术领域，具体公开了一种海上风电场与桩基施工结合的快速注浆型基础结构，包括钢管桩、注浆导管、注浆突枝管和拍门，所述钢管桩顶部与风电机组塔筒相连；所述注浆导管设置在钢管桩的内侧，所述注浆突枝管设置在钢管桩外侧；所述钢管桩周侧设置有通孔，所述注浆突枝管通过通孔与注浆导管相互连通，所述拍门设置于注浆突枝管的管口内侧；所述注浆导管中注入浆液，浆液通过注浆突枝管管口冒出，并在钢管桩周侧形成高压注浆加固体；本发明在满足桩基本身功能需求和自身强度的前提下，使大直径单桩施工与地基处理相融合，既能达到快速加固桩周土体、减少支撑结构水平位移的目的，也能减少造价，还能节约工期。
