Description

Sand quilt hanger frame for offshore wind power generation pile foundation construction

Technical Field

The utility model relates to a husky by technical field, in particular to husky by gallows that is used for offshore wind power generation pile foundation construction.

Background

The foundation of the wading building is generally a pile structure, for example, a fan foundation constructed in a shallow sea and intertidal zone, a pile immersed in water can block water flow, and then the water flow can generate a vortex flow around the pile so as to increase local water flow shear stress, and simultaneously, under the action of tide and ocean current, soil around the pile can be washed, so that silt around the pile foundation can be taken away, and thus, a pit is formed by washing and sand-washing around the pile foundation, so that the bearing capacity of the pile foundation is reduced, and further, a serious consequence of inclination and even collapse is generated. Therefore, the anti-scouring treatment for treating the offshore wading pile is a problem which must be treated seriously. The traditional treatment method is generally to pile up sand bags or lay broken stones around the pile foundation, but the sand bags and broken stones can be displaced under the impact of seawater, and particularly the stability of the pile foundation in a deep water area is limited.

The application publication number is CN104480961A (application number is 201410661498.6) of the invention patent of China for an anti-scour construction method of an offshore wind power single-pile foundation, wherein the disclosed anti-scour construction method firstly carries out reinforced design on the structural strength of a seabed and then installs a single-pile on the seabed after the seabed strength is enough. The method has high construction cost and long construction period, and cannot be widely popularized.

Chinese patent (No. CN2049567358U) discloses a sand quilt, which is characterized in that sand quilt is laid around the pile structure to protect the pile, and then reinforcement belts are only arranged on the bag body along the length direction, so that the structural firmness is poor, and the sand quilt is not easy to be laid flat and the difficulty of laying the sand quilt is high.

Therefore, a sand quilt laying structure capable of quickly laying sand around the pile is urgently needed.
