Floating suction barrel foundation construction method and floating suction barrel foundation
The invention relates to a floating suction barrel foundation construction method and a floating suction barrel foundation in the field of ocean geotechnical engineering. Flexible cloth (6) is arranged and is connected with a barrel top (10) or a barrel side wall (5) to form a closed space (8) with at least one side provided with the flexible cloth (6); during transportation, the closed space (8) is inflated so that the closed space (8) can float on the water surface; after the traction and dragging to a preset place, gas in the closed space (8) is released, the gas in the sealed space (8) is released, primary sinking is achieved by using the self weight; then, the sealed space and a soil body (11) are enclosed to form a secondary closed space (9); gas in the secondary closed space (9) is pumped out; the barrel side wall (5) is enabled to further sink by utilizing atmospheric pressure or water pressure; and grouting can also be performed in the closed space (8) at the bottom of the barrel side wall (5) to form a grouting reinforcement body (12), and the bearing capacity is improved. The method provided by the invention has the advantages that the offshore suction barrel foundation construction equipment is greatly simplified, the construction speed is high, the manufacturing cost is low, and the bearing capacity is high.
本发明涉及海洋岩土工程领域中的漂浮吸力筒基础施工方法及漂浮吸力筒基础，通过设置柔性布(6)，并与筒顶(10)或筒侧壁(5)连接，形成至少一面为柔性布(6)的密闭空间(8)，运输时，向密闭空间(8)内充气，使其漂浮于水面，牵引拖运至预定地点后释放密闭空间(8)内的气体，利用自重初步下沉，再与土体(11)围合成二次密封空间(9)，抽出二次密封空间(9)内的气体，利用大气压力或水压力促使筒侧壁(5)进一步下沉，还可以在筒侧壁(5)底部的密闭空间(8)内注浆形成注浆加固体(12)，提高承载力，本发明使得海上吸力筒基础施工设备大幅度简化，施工速度快、造价低、承载力高。
