Description

Technical Field

[0001] The invention relates to the technical field of foundation solidification, in particular to a wind farm foundation rapid solidification device and a construction method thereof. Background Art

[0002] In the construction of wind farms, foundation treatment is a key link. Since wind farm foundations are often located in complex geological environments, such as soft soil foundations, these foundations have the characteristics of low bearing capacity, high water content, and deep soft soil layers. Therefore, they must be solidified to meet the requirements of wind turbines for foundation stability. In the process of compacting soft clay by the compacting mechanism of the existing solidifying equipment, due to the stickiness of the soft clay, it will adhere to the surface of the compacting mechanism when under pressure, thereby affecting the compaction effect of the soft clay. In order to ensure the construction quality, the operator needs to frequently scrape the soft clay attached to the surface of the compacting mechanism with a scraper, which is not only time-consuming and labor-intensive, but also reduces the construction efficiency and slows down the construction progress.

[0003] A Chinese patent discloses a shallow soft clay foundation solidification treatment device (authorization announcement number CN218291901U). The patented technology can scrape off the soft clay adhered to the surface of the compaction roller at the first time through the scraper provided, so as to effectively ensure the compaction effect of the foundation. Since the scraper is in contact with the surface of the compaction roller, it is easy to wear due to friction. Through the elastic effect of the spring and the telescopic effect of the telescopic rod, the scraper can be pushed to always keep in contact with the surface of the compaction roller, thereby playing a compensation role, ensuring that the cleaning work can be carried out stably, avoiding the problem that manual cleaning is not only time-consuming and labor-intensive, but also reduces construction efficiency and slows down construction progress. The push plate provided can push the soft clay evenly before compaction, so as to ensure the flatness and uniformity of the foundation compaction, and effectively improve the quality of construction; However, it has certain disadvantages: first, the elastic force of the spring makes the scraper always stick to the surface of the compaction roller. As the scraper continues to wear, the spring will gradually change from a compressed state to an open state, which makes the pressure of the scraper on the compaction roller gradually affect. The smaller pressure does not have a good effect on the soil adhered to the surface of the compaction roller, so its cleaning method needs to be optimized; secondly, it loosens the soil through a loosening device, which does not have the function of adjusting the loosening depth, so it does not meet more usage requirements.
