韦水倒虹除险加固技术的提出与实施

Technique of Reinforcement of Prestressed Concrete Inverted Siphon in the Weishui River

针对韦水倒虹钢筋砼管道受水中推移质撞击、管道底部形成冲槽、受力钢筋磨损、钢筋截面减小、结构安全度降低等特点,提出了在钢筋砼管道底部90°范围内进行粘钢补强加固的技术方案,并论述了粘钢补强加固方案的设计原理及施工工艺。

With the impact of bedload transport, the bottom of prestressed concrete conduit was damaged and the cross-section is reduced as well as the safety. The author proposed the scheme of strengthening with bonded steel plates at prestressed concrete conduit 90° and discussed the design principle and technique of prestressed concrete conduit strengthened with bonded steel plates.
