禹州煤矿采空区灌浆处理施工及质量验收标准

摘要

禹州煤矿采空区是南水北调中线一期工程总干渠全线唯一穿越的煤矿采空区。为确保工程运行安全，按照设计要求，结合灌浆生产性试验及室内试验研究结果，对采空区实施了灌浆处理。介绍了填充灌浆、帷幕灌浆的施工工艺和技术参数的选定过程，在无具体专业施工技术规程和质量评定标准指导的情况下，结合施工实际情况，制订出适合采空区的灌浆及施工质量验收评定标准。对类似水利工程项目的基础处理具有一定的参考价值。%The main canal of Middle Route Project of South to North Water Diversion Project passes through the sole coal mined-out area, i. e. Yuzhou area. To ensure safe operation of the project with related specifications and quality evaluation standard, according to the design requirements, the grouting works are implemented by using the results of in-situ and indoor tests of grouting. Furthermore, the construction technologies of filling grouting and curtain grouting, the selection process of tech-nical parameters are introduced. Due to without acceptance and appraisal standards for construction, according to practical condi-tion, the acceptance and appraisal standards adapt to construction coal-mined out area are made out.
