一、站场内的横向排水涵管改为过轨盖板沟 上海铁路局地处华东沿海、雨量充沛,站场内排水不畅,尤其是电气集中的站场,排水问题更为重要。以往在站场设计中都单独做排水设计。为简化设计,1978年我所设计了铁路站场排水设备通用图(图号上线78—101—122),其中纵向排水用浆砌片石钢筋混凝土盖板沟,横向则沿用圆涵引出线路外侧的方法。这种圆涵因站场汇水面积不大,流量小,故一
First, the horizontal drainage culvert in the station was changed to the overpass cover ditch Shanghai Railway Bureau is located on the east coast of China. With abundant rainfall and poor drainage in the station yard, especially in the electrical depot, the drainage problem is even more important. In the past in the station design are done separately drainage design. In order to simplify the design, in 1978, I designed a general plan of railway station drainage equipment (No. 78-101-122 on the line), of which the longitudinal drainage mortar-lamellar reinforced concrete cover ditch, method. This round culvert due to the site catchment area is not large, small flow, so one
