摘要
江坪河水电站面板堆石坝基础进行灌浆试验中,对灌浆压力、浆液配比、注入率使用自动记录仪记录,自动抬动观测记录仪观测趾板抬动变形,并配置自动报警装置进行升压试验。探索在保证趾板不产生抬动破坏的前提下,尽可能地提高帷幕和固结灌浆压力的途径,灌后透水率控制在0.16～1.1 Lu之间。
The auto-monitoring recorder and alarm device are used in the foundation grouting test for Jiangpinghe CFRD to acquire the data of grout pressure,grout proportion,grout acceptance and the toe-slab upwarping,and then to investigate the way of stepping up the grout pressure within the limit that the toe-slabs don’t be raised up.The seepage rate is controlled in 0.16 ～ 1.1 Lu after the foundation is grouted.
