防撞护栏施工要做到标准化，就必须从前期施工准备、钢筋制作与安装、支立模板、浇注混凝土到后期混凝土养护等各个施工环节都严格按照施工工艺和质量控制要点进行施工，才能确保高质高效地完成防撞护栏施工。施工控制要点
In order to achieve the standardization of the anti-collision guardrail construction, we must strictly follow the construction technology and quality control points from the early construction preparation, steel bar production and installation, formwork erection, concrete pouring to the later concrete maintenance and other construction links, so as to ensure the high-quality and efficient completion of the anti-collision guardrail construction. Key points of construction control
1、测量控制点按照每5m设置一个，为标高及线形的控制打好基础，然后将防撞栏范围内的混凝土进行凿毛并清理干净。
1. The survey control points shall be set every 5m to lay a good foundation for the control of elevation and alignment, and then the concrete within the anti-collision barrier shall be roughened and cleaned.
2、钢筋加工尺寸要精准，安装时采用定位架法进行安装。根据设计图中2、3号钢筋的位置、角度和尺寸分别制作定位架，采用定位架配合盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门控制点的做法使防撞栏钢筋的标高和线形得到了有效的保障，钢筋保护层合格率可保持在90%以上。
2. The processing size of reinforcement shall be accurate, and the positioning frame method shall be adopted for installation. According to the position, angle and size of No.2 and No.3 steel bars in the design drawing, the positioning frame is made respectively, and the positioning frame is used to cooperate with the control point, so that the elevation and linear of the steel bar of the crash barrier are effectively guaranteed, and the qualified rate of the steel bar protective layer can be maintained above 90%.
