The a quarter of sufficient world average level is one of 13 poor-water countries, the world.In China, available water source mainly includes river
Flowing water, freshwater lake water and phreatic water.For the surface fresh waters resource such as river, lake, water loss mainly evaporates
With leakage, according to incompletely statistics, leakage has accounted for 80% or so of water body loss.
In the prior art, in order to solve the surface fresh waters resource leakage problems such as lake, impervious barrier, impervious barrier are mainly used
It is in the structure sheaf that man-made lake lakebed is handled using impervious material and is formed.The man-made lake newly excavated, due to lakebed soil
Short texture, lake water have leakage phenomenon.Water leaks in order to prevent, and design drawing generally all has impervious barrier structure.Prevented
After infiltration processing, the leakage of lake water is effectively controlled, and can reduce the filter loss of water to large extent.Currently, mainly use
It is geomembrane anti-seepage technology, mixing material seepage control technique and bentonite seepage control technique.
But what above-mentioned three kinds of seepage control techniques were mainly focused on is the barrier performance of material, for impervious material permeability then
Not excessive requirement.More filling soil inside antiseepage blanket in the prior art, do not have gas permeability, meet water at thick, however such as
