摘要
针对13m C频段卫星通信天线基础预埋件的高精度安装需求,从材料控制、施工工艺、动态调节与全周期监测四个维度展开研究。通过优化配筋设计(Φ14@150mm空间网格)、分次浇筑工艺(C30低热水泥+C40微膨胀混凝土)、三维可调式调节装置(X/Y/Z轴±0.5mm精度)及光纤光栅实时监测系统,实现预埋件轴线偏差≤2mm、垂直度≤0.05°的毫米级定位目标。工程实践表明,该技术使预埋件一次验收合格率达98.5%,支撑Ka波段天线波束指向误差≤0.003°,为超高频卫星通信系统的可靠运行提供技术保障。
This paper focuses on the high-precision installation requirements of embedded parts in the foundation of a 13m C-band satellite communication antenna.The study is conducted from four dimensions:material control,construction technology,dynamic adjustment,and full-cycle monitoring.Through optimized reinforcement design(Φ14@150mm spatial grid),a two-stage pouring process(C30 low-heat cement plus C40 micro-expansion concrete),a three-dimensional adjustable adjustment device(X/Y/Z-axis±0.5mm precision),and a fiber Bragg grating real-time monitoring system,the millimeter-level positioning targets of axial deviation≤2mm and verticality≤0.05°for embedded parts are achieved.Engineering practices demonstrate that this technology ensures a one-time acceptance qualification rate of 98.5%for embedded parts and supports a Ka-band antenna beam pointing error of≤0.003°,providing technical assurance for the reliable operation of ultra-high-frequency satellite communication systems.
