黑河引水工程沣峪渡槽混凝土结构病害治理

Disaster Treatment for Concrete Structures of Fengyu Aqueduct in Heihe Diversion Project

通过沣峪渡槽病害原因分析,采用新技术、新材料、新工艺加固处理,提高混凝土结构整体强度,防止混凝土结构力学性能继续劣化,延长渡槽使用寿命,保证输水安全。加固技术先进、安全可靠、经济合理、施工简便、外观效果好,值得在类似水利工程加固中借鉴。

Here,by analyzing the dangerous situations and reasons of Fengyu aqueduct,the new technology,new materials and new processings are adopted for reinforcement in order to enhance the overall strength of concrete structures,prevent the continued deterioration of mechanical properties of concrete structures,and extend the life of the aqueduct,so that the safety in water conveyance would be ensured.The results show that this reinforcement technology is advanced,safe,economic,simple to construct and of good effect in appearance,so it is worthwhile using for reference in similar reinforcing engineerings.
