第二設計院編制的跨綫石拱渡槽全路通用图已經完成,现已在全路推广使用,该图的主要内容介紹如下,以供使用单位参考。 1.孔径分8m,10m,12m。可按路塹断面組成三孔—联及单孔两种。 2.适用于单綫及单綫弯道。路堑容許最大高度为18m。 3.水槽断面有矩形及梯形两种。矩形水槽底宽为1.0m～2.0m,全宽为2.0～3.7m。梯形水槽底寬为1.75m～3.0m,全寬为3.4m～6.3m。可按水槽内水深,坡度,流速及通过流量分别选用之。 4.水槽坡度范围为i=0.2～7‰,設計流量范围Q=0.1～10m~3/sec,設計流速V≤2.5m/sec。
The second design institute compiled cross-arch stone arch aqueduct all-road map has been completed, is now in use throughout the road, the main contents of the map are as follows, for the use of units for reference. 1. Aperture points 8m, 10m, 12m. According to the road cut section composed of three holes - and single hole two. 2. For single and single curve. Cutting allowable maximum height of 18m. 3. The section of the tank has two kinds of rectangular and trapezoidal. Rectangular sink bottom width of 1.0m ~ 2.0m, full width of 2.0 ~ 3.7m. Trapezoidal sink bottom width of 1.75m ~ 3.0m, full width of 3.4m ~ 6.3m. According to the water depth, slope, flow rate and through the flow were selected. 4. Slope gradient range i = 0.2 ~ 7 ‰, design flow range Q = 0.1 ~ 10m ~ 3 / sec, design flow rate V≤2.5m / sec.
