Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0021] It can be seen from the accompanying drawings that a reinforcement combination of a suction caisson foundation and a cement-soil mixing pile includes a suction caisson foundation 1. A cement-soil mixing pile reinforcement 2 is arranged inside the suction caisson foundation 1. The suction caisson foundation 1 It includes a cylinder body 3, the lower end of the cylinder body 3 is open, and the upper end of the cylinder body 3 is provided with a cover 4, and the cover 4 is provided with a fairlead 6 and a drain valve 5, and the drain valve 5 is connected with the cylinder The inner cavities of body 3 are connected.

[0022] The outside of the cement-soil mixing pile reinforcement 2 is rectangular; the length of the cross-section of the cement-soil mixing pile reinforcement 2 is 1.0-2.0 times the diameter of the suction caisson foundation 1;...

Abstract

The invention relates to a reinforcement combination of a suction caisson foundation and a cement-soil mixing pile. The invention includes a suction caisson foundation. The interior and exterior of the suction caisson foundation are provided with cement-soil mixing pile reinforcements. The suction caisson foundation includes a cylinder Body, the lower end of the cylinder is open, the upper end of the cylinder is provided with a cover, the cover is provided with a fairlead and a drain valve, and the drain valve communicates with the inner cavity of the cylinder; the present invention uses a suction type The foundation treatment before the caisson foundation sinks makes the suction caisson foundation and the cement-soil mixing pile form a whole, so as to improve the vertical and horizontal bearing capacity of the suction caisson foundation.

Description

technical field [0001] The invention relates to a reinforcement combination of a suction caisson foundation and a cement-soil mixing pile, which belongs to the field of anchor foundations for floating offshore platforms and offshore floating wind turbines. Background technique [0002] The suction caisson foundation is a common foundation form for offshore wind power foundations and offshore platforms. Since the shallow soil is mainly composed of silt and silt, and the soil quality is relatively poor, the bearing characteristics of the suction caisson foundation are greatly affected by the shallow soil. At the same time, under the influence of wind, waves, currents and other factors under the complex marine environment, as well as the long-term uplift load, the suction caisson foundation produces large horizontal and vertical bearing capacity and displacement, threatening the safety of the superstructure. [0003] As a new type of floating offshore wind turbine foundation, ...
