某大坝是混凝土重力坝,根据温控要求,坝体设置1 ~2条纵缝,缝面设置水平键槽,在坝体混凝土达到稳定温度后进行接缝灌浆。
A concrete gravity dam with 1 ~ 2 longitudinal seams and level keyways in seam surface was grouted when the concrete stays a stable temperature.
提出灌浆相关控制指标,使在不影响原坝体稳定的前提下,充分发挥湿化变形效果。
Besides, the relative controlling parameters for split grouting are put forward so as to make full use of wetting deformation without influencing the stability of dam.
可进行普通灌浆、GIN法灌浆、压水试验记录及稳定水位测量。
It can be used for data recording of common grouting, GIN grouting, pressing water experiment and measuring stable water level.
结果表明:(1)在小麦开花后21天以前冠层温度的各遗传参数的值均较小,且变化不稳定,在开花后21天以后,均较大,且随灌浆进程有增加的趋势。
The results showed that: (1) Genetic parameters of canopy temperature were smaller and unstable before 21 days after anthesis, but were bigger and increased gradually after 21 days after anthesis.
为保证钢衬整体结构的稳定性,通常都对脱空进行接触灌浆,一般以水泥灌浆为主,化学灌浆则用于水泥灌浆后的辅助补强。
To ensure stability of the whole structure of steel-lined, grouting is always applied into void treatment in which chemical grouting was supplementary for cement grouting.
