浑河沈阳段砂山橡胶坝改建方案研究

摘要

本文针对浑河沈阳段砂山橡胶坝运行存在的问题,提出了四种解决方案。1.将一孔改为小坝段;2.将一孔改成钢坝闸;3.将一孔改成气动盾形闸门;4.在橡胶坝一侧修建调节闸。通过比较,调节闸较其他方案更有优势,在满足灌溉期过流要求的同时,可实现低水头流量调节且操作灵活,运行更加安全可靠。本文针对解决橡胶坝运行不足的问题提出了多种见解,其结论可供其他工程参考借鉴。%This paper is In reaction to the existing problem of Shashan rubber dam in Shenyang river sector of Hun river.Four transformations was proposed.The first is changing one dam bag smaller;the second is changing one dam bag to steel dam gate;the third is changing one dam to pneumatic brake;the fourth is building regulation gate. Through comparison, regulation gate is the best way due to the stability and flexibility for adjusting low head flow under irrigation condition.This paper presents a few methods to solve the problems in rubber dam, which are the reference for practical engineering.
