木兰倒虹吸管始建于20世纪60年代,1978年木质管道因腐蚀漏水而报废,改为两条钢管承担输水,钢管内外采用涂漆防腐,效果极差。针对1998年10月实施的木兰倒虹吸钢管内壁防腐工程,通过管内最大冲刷力计算、施工要点介绍、近15 a运行效果检验,得出在倒虹吸钢管内实施水泥砂浆抹面防腐是可行的。

Mulan inverted siphon straw was founded in twentieth century 60's,it was abandoned in 1978 due to pipeline corrosion and water leakage,and two steel pipelines,with internal and external painting anticorrosion on them,was built to transmit water and anticorrosion effect was not good.In terms of internal anticorrosion project conducted in October,1998,through the maximum scouring force calculation,construction point descriptions and operation effect examination,it is concluded that mortar anti-corrosion is feasible for inverted siphon pipe inner anti-corrosion.
