山区公路的特点是:纵坡大、弯道急、边坡高、雨季山洪大。因此,做为防洪排水工作,对养好公路就有很大作用。从我们历年来在养护工作中的经验教训看,做好防洪排水工作的标准是:路面、路肩、天沟、侧沟、桥梁、涵洞六不积水、不冲刷。怎样才能做到六不积水不冲刷呢? 一、照标准施工:施工时照标准做成,在桥涵方面容易做到,而路基路面上的路拱、超高、路肩的坡度,往往不注意,有部分做的不够。从近年新接养的道 The characteristics of mountain roads are: Longitudinal slope, bend urgent, high slope, heavy rain torrents. Therefore, as flood control and drainage work, have a great role in raising roads. From our experience and lessons in conservation work over the years, the standards for flood control and drainage work are: pavement, shoulder, gutter, side ditch, bridges, culverts, no water, no erosion. How can we do six non-flooding does not wash it? First, according to the standard construction: construction according to standard, easy to do in the bridge and culvert, and the roadbed on the road, ultra-high, the shoulder slope, often not pay attention Some do not do enough.
