摘要
碾压胶结砂是一种创新技术,具有充分利用河道清淤的弃砂、经济、环保的特点。新型防渗材料膨润土防水毯(GCL)的透水性在≤5×10-11m/s以下,既可满足防渗要求,又具有一定的微渗性,不会隔断与防水层下的水力联系。无毒无害,具有良好的环保性能。在已取得较为系统的室内试验研究成果的基础上,还需对该类防渗结构的整体防渗抗冲刷效能及碾压工艺等问题,进行仿真试验来验证它的可行性。
The first stage project of Sbijiazhuang Hutuo River comprehensive improvement of flood control and environment rehabilitation is the priority project of the municipal government, and the important action of the provincial capital to realize ＂great changes in three years, the beautification program＂. The rolled cemented sand is a kind of innovation technology that makes use of the waste gravel of river course desilting, which is economical and of environmental protection. The water permeability of Geosynthetic Clay Liner （GCL）, the new impervious material is below 45×10^-11 m/s, satisfying seepage prevention and also having some infiltration, will not separate the hydraulic relationship with waterproof layer. It is nontoxic, harmless and of environmental protection. Obtaining more systematic laboratory test achievements, it shall implement the sim- ulation testing for its feasibility whereas the overall anti-seepage anti-washout potency and roller compaction operation
