新疆河流绝大部分是多沙河流,泥沙处理是渠首工程设计中的关键问题。已建的400多座引水渠首中,弯道式渠首的应用较为广泛。针对不同时期弯道式渠首的优缺点及存在问题进行了总结,着重对第三代弯道式渠首的设计特点、优化布置及弯道式渠首的技术发展、泥沙处理、防冰冻措施等问题进行了探讨,对上游、下游整治工程,弯道整治段,河道稳定宽度的设计及灌溉与发电结合问题的解决提出了有效方案。
The vast majority of rivers in Xinjiang are sandy rivers. Sediment treatment is the key issue in the design of canal projects. Among the more than 400 aqueducts that have been built, the application of curved channel heads is more extensive. In view of the advantages and disadvantages of the curved channel heads in different periods and their existing problems, the author summarizes the design features of the third generation of curved channel heads, the optimized layout and the technical development of curved channel heads, sediment treatment and anti-freezing Measures and other issues were discussed, the upstream and downstream remediation project, the bend section, the stability of the width of the river and irrigation and power generation to solve the combination of the proposed solution.
