摘要
为了解决输水洞渗漏现象,保证水库发挥应有的经济效益,对九龙水库输水洞洞身混凝土工程、岩石基础及混凝土垫层等进行科学检测,明确了洞身裂缝的产生原因,根据检测结果,对地基沉陷及洞身裂缝进行分析,通过施工过程的回顾、结构安全的复核、加固处理方案的比选,确定出输水洞地基固结灌浆、洞身设钢管衬砌、洞壁回填混凝土的方案。经过施工处理之后,输水洞漏水情况得到完全解决,蓄水位已达到278m,证明此方法安全高效。研究成果对水库输水洞渗漏处理和保障水库安全运行具有一定的理论意义和实践价值。
In order to solve the leakage phenomenon of water conveyance tunnel,ensure economic benefit of the reservoir,through scientific testing of the water conveyance tunnel concrete engineering,rock foundation and concrete cushion of the Kowloon Reservoir,define the causes of the generation of the water conveyance tunnel cracks,through construction review,safety check for structures,reinforcement program selection,the project foundation consolidation grouting of water conveyance tunnel,steel pipe lining of the culvert and concrete backfill of cavity wall is determined. The situation of water conveyance tunnel leakage is fully solved by using construction treatment measures,storage water level has reached 278 m,and it proved the method is safe and effective. Research results have certain theory significance and practical value for water conveyance tunnel seepage treatment and ensuring security running.
