上荆江数字航道水位站观测设施建设主要技术对策

摘要

水位站观测设施是上荆江河段数字航道建设的重要内容之一。根据岸坡、河床地质条件的不同，在水位站选址、水尺选型及施工、水准点及观测路施工、压力管线的敷设特别是气容的安装等方面进行研究和优化，提出了有针对性的施工方案。创新性地把直立式和倾斜式水尺相结合，解决特殊地理条件下水位观测的难题。设计制作了不同的气容安装方法，解决不同河床边坡、不同水文环境下探头固定的问题。%The stage gauging station observation facility is an important content of Jingjiang digital waterway construction.Based on the geologic conditions of the bank slope and riverbed we carry out a research and optimization on the stage gauging station site selection gauge type selection and construction benchmark and observation road construction as well as the pressure pipe line laying esp.the air-capacitor installation and propose relevant construction schemes.The innovation combination of the vertical and tilting gauge solved the problem of stage observation under special geologic condition .Different installation methods for the air-capacitor of are designed to deal with the probe fixing for different bank slopes and different hydrological conditions.
