补充资料:通航建筑物
通航建筑物 navigation structure 用于克服集中水位落差或地形障碍而升降或通过船舶的水工设施。又称过船建筑物。通航建筑物按功能可分为升降船舶的建筑物和通过船舶的建筑物两类。升降船舶的建筑物又可分为船闸与升船机两种基本型式。此两种型式的通航建筑物在水利枢纽中用以克服集中于拦河坝的水位差,使船舶从一个水位提升或下降至另一水位,实现船舶航行过坝的目的。通过船舶的建筑物包括航运隧洞与航运渡槽,是在人工运河上常需采用的通航建筑物。当人工运河穿越高山时,为减少大量开挖而开凿隧洞过船。当人工运河跨越山谷或需架空时,则需建设航运渡槽,以使船舶在架空的渡槽中通过。 船闸与升船机相比具有容纳船队的较大闸室,在中低水头下有较大的通过能力,可适应各种尺度的船队过闸,采用广泛。升船机在高水头情况下适应性较强,但机电设备量大,制造与安装精度要求较高。 |
