文章在卧虎山水库放水洞工程病害分析的基础上,对坝下浆砌石廊道来说急需解决的主要问题是坝体向廊道内的渗漏稳定问题;对输水管道考虑拆除更换,放水洞进口采取增建进口塔架,增加放水洞检修闸门及更换相关电气设备等措施,并对放水洞提出了针对高压喷射灌浆加固、开挖坝体加固及新建放水洞方案进行了经济及技术比较,最终确定了新建放水洞、封堵原放水洞的除险加固方案。
Based on the analysis of the diseases of the diversion tunnel in Wohushan Reservoir, the main problem that needs to be solved urgently for the dam masonry corridor is the problem of the seepage stability in the gallery to the corridor; the disassembly and replacement of the water pipeline, The intake of water diversion tunnel adopts such measures as increasing the import tower, increasing the floodgates maintenance gates and replacing the relevant electrical equipment, and puts forward the plans for water diversion tunnel for the projects of high-pressure jet grouting, excavation reinforcement and new water diversion tunnel. Comparison, and ultimately determine the new water hole, plug the original dive hole reinforcement program.
