Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of fluidized solidified soil for offshore wind power foundations, and specifically relates to a preparation device for fluidized solidified soil. Background Art
[0002] With the rapid development of the offshore wind power industry, single pile foundations currently account for about 65% of wind farms due to their unique advantages such as simple structure, convenient processing and transportation. Due to the long-term scouring of water flow, single piles form scour pits on the seabed around the underwater foundation, which greatly reduces the bearing capacity of the foundation, increases the foundation overturning moment and the horizontal displacement of the upper structure, and brings great safety hazards to the underwater foundation structure. It is urgent to take necessary anti-scour measures to maintain the safety, stability and durability of the foundation structure. Traditional anti-scour solutions mostly use riprap protection, sand blanket protection and row protection, but there are still gaps in the contact between such anti-scour solutions and the soil layer around the pile. During the long-term water scouring process, as the gaps continue to expand, the anti-scour capacity continues to decline, and the anti-scour life cycle is shortened.
[0003] As a new type of single pile anti-scour technology, solidified soil is initially in a fluid state and can be blown into the scour pit through a conduit. After solidification, it can form an integral protective belt around the underwater foundation, with good protective effect. In recent years, it has gradually been applied in underwater foundation anti-scour projects. At present, the construction process of on-site mixing, pumping and blowing of fluidized solidified soil mostly adopts a rough process based on the huge demand on site. Under the premise of ensuring on-site work efficiency, the quality of fluidized solidified soil is difficult to guarantee. In addition, the dust pollution on the construction site is relatively large, which affects the health of the workers.
[0004] Based on this, it is necessary to improve the existing construction equipment of fluidized solidified soil to improve the quality of fluidized solidified soil while ensuring the efficiency of on-site construction. Utility Model Content
