Arrangement method of road surface water interception and drainage structure at upstream of flat slope section of road surface
The invention relates to the technical field of road engineering, in particular to a pavement flat slope section upstream road surface water interception and drainage structure setting method which comprises the following steps: investigating the catchment length l of a pavement, the pavement gradient i of the catchment length and the rainfall intensity of a pavement section; the width of the interception drainage structure is determined according to the formula d = 100 * akl + 1, in the formula, d is the width of the drainage structure, and the unit is cm; l is the catchment length, and the unit is m; a is the maximum rainfall intensity coefficient; k is a gradient coefficient; an interception drainage structure is arranged on the upslope side of the flat slope section, the width of the drainage structure is determined according to the previous steps, and the depth of the interception drainage structure is consistent with the thickness of the surface layer. According to the arrangement method of the road surface flat slope section upstream road surface water interception and drainage structure, the interception and drainage structure with the proper width is arranged on the flat slope section upslope, input of the flat slope section road surface water can be reduced, the accumulated water thickness is reduced, and driving safety in rainy days is guaranteed; the interception drainage structure is arranged, the pavement does not need to be dismantled to reconstruct the drainage pavement, and the treatment cost is low.
本发明涉及道路工程技术领域，尤其涉及一种路面平坡段上游路表水截留排水结构设置方法，包括：调查路面的汇水长度l、汇水长度的路面坡度i以及该路面路段的降雨强度；根据公式：d＝100*akl+1确定截留排水结构的宽度，式中，d为排水结构宽度，单位为cm；l为汇水长度，单位为m；a为最大降雨强度系数；k为坡度系数；平坡段上坡一侧设置截留排水结构，排水结构的宽度根据前面步骤确定的，截留排水结构的深度与面层厚度一致。本发明的路面平坡段上游路表水截留排水结构设置方法，通过平坡段上坡设置合适宽度的截留排水结构，能够减少平坡段路表水的输入，降低积水厚度，保障雨天行车安全；而且设置截留排水结构，无需拆除路面重建排水路面，处理成本低。
