公路盖板涵洞的施工放线与建筑施工放线虽有不少不同之处,但也有许多相似之处,只要我们把建筑施工放线的基本知识和作法结合公路设计图灵活运用,就可以作为公路盖板涵洞的施工放线。一、放线1.根据设计图给的中心线和主要分部工程尺寸,计算出各分部工程的中心线和边线,如图中台墙的 L_1、L_2、B_1、B_0,上下游八字墙的 L_3、
Although there are many differences between the construction of highway culvert culverts and the payoff of construction, there are many similarities. As long as we can make use of the basic knowledge and practice of building demolition in conjunction with the flexible design of road design, Highway cover culvert construction release. First, put the line 1. According to the design drawings to the center line and the main division of the project size, calculate the center line and edge of each branch of the project, as shown in the Taiwan wall L_1, L_2, B_1, B_0, L_3,
