Suction penetration construction method for underwater large cylinder foundation
The invention discloses a suction penetration construction method for an underwater large cylinder foundation, which comprises the following steps: step 1, preparing a top cover which comprises a top cover plate, a pump skid mounted on the top cover plate and aligned with a pump opening, a plurality of top cover lifting lugs mounted on the top cover plate and a plurality of hydraulic connecting mechanisms mounted on the edge of the top cover plate; secondly, the top cover is hung through a crane ship, and the top cover is installed on the top of the large cylinder through a plurality of hydraulic connecting mechanisms; step 3, hoisting and positioning the foundation; fourthly, an exhaust and drainage valve is opened firstly, then a lifting hook of the crane ship is gradually lowered, the large cylinder foundation is put into water, and the large cylinder foundation overcomes resistance under the self-weight effect to achieve penetration; 5, the water pump is started, and water in the large cylinder is discharged through the water pump and sinks till the large cylinder foundation sinks to the designed elevation; and 6, water is injected into the large cylinder through a water pump, and then the top cover is lifted out of the water surface through a crane ship. According to the invention, the investment on large-scale construction equipment can be reduced.
本发明公开了一种水下大圆筒基础的吸力沉贯施工方法，包括以下步骤：步骤一，准备顶盖，顶盖包括顶盖板、安装在顶盖板上并与泵口对准的泵撬块、若干安装在顶盖板上的顶盖吊耳和若干安装在顶盖板的边缘的液压连接机构；步骤二，利用起重船起吊顶盖，并利用若干液压连接机构将顶盖安装在大圆筒的顶部；步骤三，基础起吊和定位；步骤四，先打开排气排水阀，接着逐渐降低起重船的吊钩将大圆筒基础下放入水中，使大圆筒基础在自重作用下克服阻力实现沉贯；步骤五，启动水泵，使大圆筒内的水体通过水泵排出并下沉，直至大圆筒基础下沉至设计标高；步骤六，通过水泵向大圆筒内注水，再通过起重船将顶盖吊出水面。本发明能降低对大型施工设备的投入。
