Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The protection scope of the present invention is not limited only to the description of this embodiment.

[0028] Such as Figure 1~3 As shown, a suction-type cylindrical foundation sinking cylinder deviation correction and reinforcement device, the sinking cylinder includes two parts: the cylinder cover 3 and the cylinder body 2; in this embodiment, the sinking cylinder is made of steel with a diameter of 4m, a height of 4.5m, and a wall thickness of 2cm. The cylinder body; the cylinder cover 3 is welded on the cylinder body 2 to form an inverted cylinder shape with the upper end sealed and the lower end open; the cylinder cover 3 is provided with a drain valve 4; the drain valve 4 is connected to the water pump. In this embodiment, 8 copper pipes or steel pipes 6 with a diameter of 5 cm and a length equal to the height of the inner c...

Abstract

The invention belongs to the technical field of marine structure foundations, and discloses a suction cylindrical foundation sink tube deviation correction and reinforcing device. The device has the advantages that a suction cylindrical foundation sink tube serves as a cathode, an attached copper tube or steel tube serves as an anode, electroosmosis is formed on the periphery of the wall of the sink tube, the friction resistance of a contact surface between the wall of the sink tube and deep sea soil is weakened during the penetration of the sink tube, and the penetration efficiency is improved; when a suction cylindrical foundation is inclined, the effect of deviation correction is achieved through electroosmosis in a corresponding position; finally, the strength of soil of the interior of the sink tube and the wall of the sink tube are improved through a chemical electrodialytic method, and the overall uplift bearing capacity of the suction cylindrical foundation is improved. The technical scheme is convenient for construction and good in economical efficiency.

Description

technical field [0001] The invention belongs to the technical field of marine structure foundations, and in particular relates to a device for rectifying and reinforcing a sunken tube of a suction-type cylindrical foundation and a construction method thereof. Background technique [0002] Suction cylindrical foundation, as an excellent form of marine foundation, has been widely used in deep-sea oil production platforms and marine floating structures. Compared with the traditional pile foundation, the suction cylindrical foundation has the advantages of simple installation, low cost and high construction efficiency. [0003] The installation and sinking process of the suction cylindrical foundation is divided into two steps: the first step is to sink the suction cylindrical foundation to the specified depth under the action of its own weight; the second step is to pump out the slurry water in the sinking tube to form a Negative pressure, the suction type cylindrical foundati...
