一、施工准备1.测理放样首先应根据设计图纸放出中心线及边线,设置胀缝、缩缝、曲线起讫点和纵坡转折点等桩位,根据放好的中心线及边线,在现场核对施工图纸的混凝土分块线。放样时为了保证曲线地段中线内外侧车道混凝土块有较合理的划分,必须保持横向分块线与路中心线垂直,对测量放样必须经常进行复核。
First, the construction preparation 1. Management and setting out 1. First of all should be based on the design drawings release centerline and edge lines, set expansion joints, shrinkage, curves starting and ending points and longitudinal turning point piles, according to the centerline and edge of the line, on-site check Concrete block line for construction drawings. In order to ensure a more reasonable division of concrete blocks on the inside and outside of the midline in the curve area during lofting, the transverse block lines must be kept perpendicular to the centerline of the road, and the survey must be checked frequently.
