摘要
通过室内试验,研究一种新型注浆材料(VCH)的主要性能参数及其在动水条件下的材料特性。通过试验测定不同水灰比、不同水泥浆与外加剂体积比、不同温度下材料的初终凝时间;通过试验测定浆液3 h的结石率;基于现场动水注浆治理的材料与工艺要求,测定材料在不同水流速中浆体留存率与可泵性;依据材料性能和现场工况确定VCH材料工程应用的最佳配合比,研究VCH注浆材料在动水注浆治理中的应用。
By the laboratory experiments,main performance parameters and characteristics under dynamic water condition of a new type grouting material are studied.The initial/final setting time of the grouting material under different water-cement ratios,different volume ratios of slurry to admixture and different temperatures are tested.The stone rate（3 h） of material is tested.Based on the material and process requirements of dynamic water grouting engineering,slurry retention rate with different water velocities and the pumpability after initial setting time are tested.According to the performance parameters of grouting material and the field condition,the optimum mixture ratio of the new grouting material is determined.The operation technology of dynamic water grouting material is studied.
