Suction bucket foundation with anti-pull steel pipe pile and mounting method thereof
The invention discloses a suction bucket foundation with an anti-pull steel pipe pile and a mounting method thereof. The suction bucket foundation comprises a bucket body and an anti-pull pile mechanism. The bucket body is of a bucket-shaped structure with an open bottom and a sealed top, and an inner bin is formed in the bucket body. The bucket body comprises an inner bucket wall and an outer bucket wall, and a hollow interlayer is formed between the inner bucket wall and the outer bucket wall. The anti-pull pile mechanism is arranged in the hollow interlayer and can vertically slide along the hollow interlayer. The anti-pull pile mechanism comprises a base and the anti-pull steel pipe pile. The use method comprises the following steps that (1) the bucket body sinks due to the dead weight; (2) water is extracted out of the inner bin, and the bucket body continues to sink; (3) the anti-pull steel pipe pile stretches out of the hollow interlayer and penetrates into a seabed; and (4) high-pressure water in the hollow interlayer is drained to underwater grouting liquid to fill the hollow interlayer, and after the underwater grouting liquid is solidified, the steel pipe pile and the bucket body form a whole. According to the suction bucket foundation with the anti-pull steel pipe pile and the mounting method thereof, the anti-pull steel pipe pile can penetrate into the seabed, theanti-pull bearing capacity of the suction bucket foundation is improved, and the problems of soil blocking and material waste caused by bucket length increase and bearing capacity improving are solved.
本发明公开了一种带抗拔钢管桩的吸力桶基础及其安装方法，包括桶体和抗拔桩机构，桶体为底部开口、顶部密封的桶状结构并且其内部形成内舱，桶体包括内桶壁和外桶壁，内桶壁和外桶壁之间形成中空夹层，抗拔桩机构设置于中空夹层内并可沿中空夹层上下滑动，抗拔桩机构包括底座和抗拔钢管桩；使用方法如下：(1)桶体自重下沉；(2)内舱抽水使桶体继续下沉；(3)使抗拔钢管桩从中间夹层伸出并贯入海床中；(4)使中空夹层内的高压水排出至水下灌浆液充满中空夹层，待水下灌浆液凝固使钢管桩与桶体成为一体；本发明能抗拔钢管桩贯入海床提高吸力桶基础的抗拔承载力，解决了通过加深桶长提高承载力产生的土塞以及材料浪费的问题。
