京沪高铁特殊地段风屏障基础施工工艺

Wind Barrier Foundation Construction Technology on Special Section of Beijing-Shanghai High-speed Railway

结合京沪高铁工程实例,详细阐述了风屏障基础施工的底面及侧面凿毛、打眼(竖向钻眼与水平钻眼)、清孔、注胶植筋、钢筋绑扎、模板支立、混凝土浇筑、养护等施工工艺及质量控制,可为类似工程提供借鉴。

Combined wind barrier construction of the Beijing-Shanghai high-speed rail technology,the paper introduces the process and quality control technologies concerning wind barrier： the bottom and side chiseling,drilling（vertical drilling and horizontal drilling）,reinforced eye Khong,plastic injection anchorage regulatory requirements,wind barrier bolt anchorage steps,steel banding,the template support legislation reinforcement,concreting,maintenance and construction process,which provides reference for similar projects.
