摘要
山西省万家寨引黄工程连接段土建工程国际V标隧洞衬砌采用钢筋混凝土六边形预制管片,回填灌浆的质量问题成为影响工程质量的关键所在。在灌浆施工中,通过每天对灌浆资料的分析与整理,对可能存在的灌浆缺陷位置进行预测,及时发现灌浆工作中的不足,并将此分析结果进行应用,作为回填灌浆质量检查孔布孔的一种依据,以达到进行压水试验和抗压强度实验的最终目的,有效保证了施工质量。
Hexagon precast pipe element of reinforced concrete is adopted for the tunnel lining in the project of civil works Lot V of Wanjiazhai Yellow River Diversion Project in Shanxi Province. The quality of backfill grouting is a key to the project quality. During this period, grouting data are analyzed and collected daily, the locations of potential grouting defects forecasted, the inadequate points are found out timely. The analyzed results are used for distributing quality checking holes of backfill grouting in order to carry out water pressure and compressive strength tests to ensure the construction quality effectively.
