Limestone Reservoir Horizontal Impervious Material And Performance Experimental Study

The leakage of reservoir in limestone area is relatively common. The form of leakage is variety. Workers of water conservancy engineering are troubled by how to do a good job in limestone reservoir seepage. This study of the blanket of3:7lime soil and adding bentonite waterproof blanket is to make the permeability analysis. Through the validation of the impervious performance, it can obtain support of theory analysis and more impervious material selection of the work of seepage control in limestone reservoir.The3:7lime soil used30%lime and70%loess to mixed and backfill, and then through compaction in different layered. This is a relatively economical processing method, it can obtain raw material locally, and it is widely applied in the ground treatment, so it can achieve good application effect. The abbreviation of bentonite waterproof blanket is GCL. It is a new type of ecological environmental protection of impermeable material. It has good flexibility, density, and good environmental protection, strong construction and the like. So it has a widespread application in canal seepage control and subway project.In this experiment, the main research contents are as follows:1、For the example of Wang Jinzhuang reservoir in She Xian of Hebei province, samples of3:7lime soil extracted from the construction site to make a study of penetration in the lab, and to analyze the impervious performance.2、Take the loess and lime of the project to make soil column and lime soil column in accordance with the practical engineering compactness in the lab to analyze,study and make a contrast.3、Added bentonite waterproof blanket in the soil column and3:7lime soil column, through experimental of bentonite waterproof blanket in different cover layer to analyze impervious performance covered with different depth.
