仁宗海水库电站压力管道下斜段回填混凝土灌浆后冲击回波法质量检测

Renzonghai Reservoir Pressure Pipe Ramp at Power Plant Segment Backfill Grouting Concrete Impact-echo Method Quality Testing

仁宗海水库电站压力管道下斜段在回填混凝土时,因围岩裂隙水涌出,造成回填混凝土水泥浆随裂隙水而流失,经对该段进行补强灌浆处理后,为保证回填混凝土及补强灌浆质量,需对该段回填混凝土进行特殊质量检测,经对各种质量检测进行对比,最终选择冲击回波法进行质量检测,并对该质量检测方法进行分析,以便在类似工况下推广应用。

The next station pressure pipe inclined section Renzonghai reservoir when backfill concrete,because water gushing fissure surrounding rock,causing fractures backfilled with concrete grout water loss,the segment is reinforced by grouting process,to ensure the backfill concrete and reinforcing grouting quality,we need the special segment backfill concrete quality testing,based on a comparison of various quality testing,the final choice impact echo method for quality testing, and analysis of the quality inspection method for similar conditions next application.
