抗浮锚杆桩在风机基础施工中的应用研究

Research on the Application of Anti-floating Anchor Piles in Wind Turbine Foundation Construction

随着科技的发展和能源消费结构的改变,能源结构也在发生着变化,风能利用是推进能源的转型方式之一。然而,在风机建设过程中,因特殊的地质条件,为了平衡基础底板所受地下水上浮力不均匀的情况,需要在风电基础中应用抗浮锚杆桩技术。文章首先对风机基础抗浮锚杆桩进行概述,介绍了其工作原理和应用场景,然后通过分析风机基础水文、地质特征,设计了独立基础抗浮锚杆桩,然后从施工准备、施工流程、施工注意事项三个方面研究抗浮锚杆桩施工工艺在风机基础施工中的应用,并对风机基础中抗浮锚杆桩的质量控制进行分析,以此为同类工程提供参考。

With the development of science and technology and the change of energy consumption structure,the energy structure is also changing.Wind energy utilization is one of the ways to promote energy transformation.However,in the process of wind turbine construction,due to the special geological conditions,in order to balance the uneven buoyancy of groundwater on the foundation slab,it is necessary to apply anti-floating anchor pile technology in wind turbine foundation.This paper first gives an overview of anti-floating anchor pile of wind turbine foundation,introduces its working principles and application scenes,and then designs the anti-floating anchor pile of independent foundation by analyzing the hydrological and geological characteristics of wind turbine foundation.Then,the application of anti-floating anchor pile construction technology in wind turbine foundation construction is studied from three aspects:con-struction preparation,construction process and construction precautions.Besides,the quality control of anti-floating anchor pile in wind turbine foundation is analyzed,so as to provide references for similar projects.
