浅谈跋山水库放水洞加固工程中的施工技术

On the construction technology in drainage tunnel reinforcement project of Bashan Reservoir

跋山水库放水洞经过40年的运行,存在进口段、斜坡段及闸墩钢筋混凝土老损碳化、剥落,衬管裂缝漏水,闸门老化锈蚀、面板变形等问题。本文针对工程存在的问题,提出了组合技术加固措施,并详细阐述了施工技术。从多年来的运行状况来看,加固处理技术可靠,效果显著。

Bashan Reservoir drainage tunnel was operated for 40 years. It has problems of reinforced concrete aging carbonization and peeling in entrance section,slope section as well as gate pier,liner tube crack and leakage,gate aging and rusting,panel deformation,etc. In the paper,combination technology reinforcement measures are proposed aiming at the problems in the project. Construction technology is described in detail. Reinforcement treatment technology is reliable with significant effect from the perspective of operation status for many years.
