水文缆道是水文站测流、取沙最主要的设备。目前全省水文系统建有水文缆道70余处。由于水文缆道的大多数部件暴露在野外,遭受人为或自然破坏的机率较大。笔者根据多年工作实践,提出水文缆道设计与养护中应注意的几个问题,供参考。1 支柱脚部的连接。支柱脚部的连接形式有固接与铰接两种。虽然这两种设计方法在理论上是可行的,但笔者认为最好不用铰接,尤其不要采用球铰连接,因为球铰连接,其支柱的稳定全靠拉线 Hydrologic cableway hydrological station flow measurement, take the sand the most important equipment. At present, there are more than 70 hydrological cableways built in the province’s hydrological system. As most of the components of the hydrological cableway are exposed to the wild, human or natural damage is more likely. According to many years of practice, the author proposes several problems that should be noticed in the design and maintenance of hydrological cableway for reference. 1 pillar foot connection. Pillar foot connection form has two kinds of fixed and hinged. Although these two design methods are theoretically feasible, I think it is best not to hinge, in particular, do not use the ball hinge connection, because the ball hinge connection, the stability of the pillars rely entirely on the pull line
