Suction type foundation penetration equipment and negative sinking construction method thereof
The invention discloses suction type foundation penetration equipment and a negative sinking construction method thereof. The penetration equipment is composed of a rack, a deepwater electric pump assembly arranged in the rack, a water pipe valve group connected with a pump suction opening and an outlet of the deepwater electric pump assembly through flanges, and a connector assembly installed on the lower portion of the rack. A connector assembly with multi-way connection is adopted to be connected with a suction type foundation with an inner spraying and flushing pipeline, through synchronous water injection ground breaking and suction silt discharging, silt in a barrel is discharged, the influence of an inner soil plug is eliminated, and penetration under the mud surface is achieved; and meanwhile, a double-pump series connection pressurization mode is adopted, it is ensured that the penetration negative pressure is increased, the top of the inner cylinder is more tightly attached to the mud surface and deeply penetrates into the position below the seabed mud surface, and long-term in-place stability of the suction type foundation can be achieved without special anti-scouring treatment. The suction type foundation can be accurately installed at the needed position and the set depth, the installation precision and long-term structural stability are effectively guaranteed, and good economic benefits are achieved.
本发明公开了一种吸力式基础的沉贯设备及其负沉施工方法，沉贯设备由机架，以及其内部的深水电泵组件，与深水电泵组件泵吸口及出口通过法兰连接的水管阀组，以及安装于机架下部的接口组件构成，采用带多路连接的接口组件与有内喷冲管线的吸力式基础连接，通过同步注水破土和抽吸排淤，将筒内的淤泥进行排出，消除内土塞影响，实现沉贯到泥面以下；同时采用双泵串联增压方式，确保沉贯负压的提高，实现内筒顶更紧密的贴合泥面，深度贯入到海床泥面以下，无需特殊的防冲刷处理即可实现吸力式基础的长期在位稳定，本发明采用沉贯设备施工，可精准的将吸力式基础安装到需要的位置、设定的深度，有效的保障安装精度和长期结构稳定，有很好的经济效益。
