Offshore large-diameter tubular pile foundation anchoring technique and construction method
The invention relates to the technical field of tubular piles, and discloses an offshore large-diameter tubular pile foundation anchoring technique and a construction method. According to the offshore large-diameter tubular pile foundation anchoring technique and the construction method, the offshore large-diameter tubular pile foundation anchoring technique comprises a seabed surface, a high water level and a large-diameter tubular pile, an inner pulling anchor rod is arranged in the large-diameter tubular pile in a penetrating and inserting mode, a sleeve is connected to the outer side of the inner pulling anchor rod in a sleeving mode, a construction platform is fixedly connected to the outer side of the large-diameter tubular pile, a vertical anchor rod is fixedly connected to the inner wall of the large-diameter tubular pile, the diameter of the large-diameter tubular pile is larger than 5 m, the inner pulling anchor rod obliquely penetrates through the large-diameter tubular pile and extends into a certain depth of a soil body, and the pile length of the large-diameter tubular pile is not limited to loads. The offshore large-diameter tubular pile foundation anchoring technique has the advantages of the simple structure and novel design and can be suitable for various stratums of the seabed, the depth of the tubular pile embedded into the soil body can be effectively reduced, the pile length is reduced, the construction difficulty is reduced, and the cost of single-pile foundation structure materials, transportation, construction and the like is reduced.
本发明涉及筒桩技术领域，且公开了一种海上大直径筒桩基础锚固技术及施工方法。该海上大直径筒桩基础锚固技术及施工方法，包括海底面、高水位和大直径筒桩，所述大直径筒桩内穿插设置有内拉锚杆，所述内拉锚杆的外侧套接有套管，所述大直径筒桩的外侧固定连接有施工平台，所述大直径筒桩的内壁固定连接有竖向锚杆，所述大直径筒桩直径大于5m，所述内拉锚杆斜穿大直径筒桩并延伸到土体一定深度内，所述大直径筒桩桩长不受荷载限制。本发明，结构简单，设计新颖，可有效减少筒桩嵌入土体的深度，减少桩长，降低施工难度，降低单桩基础结构材料、运输、施工等成本，可适用于海底各种地层。
