Description of drawings
Fig. 1 is that the master of a specific embodiment of the utility model looks cross-sectional schematic.
The specific embodiment
In order more to be expressly understood the technology contents of the utility model, the special following examples of lifting specify.Need to prove; The diagram that is provided in this embodiment is only explained the basic conception of the utility model in a schematic way; Satisfy only show in graphic with the utility model in relevant assembly but not component count, shape and plotted when implementing according to reality; Kenel, quantity and the ratio of each assembly can be a kind of random change during its actual enforcement, and its assembly layout kenel also maybe be more complicated.
See also shown in Figure 1ly, the dual waterproof blanket of overlay film swell soil of the utility model comprises from top to bottom the density polyethylene film with high layer of fitting successively 1, first layer of cloth 2, bentonite bed 3 and second layer of cloth 4.
Said first layer of cloth 2 can be any suitable layer of cloth with said second layer of cloth 4, sees also shown in Figure 1ly, and in the specific embodiment of the utility model, said first layer of cloth 2 is nonwoven layer, and said second layer of cloth 4 is base fabrics.
First layer of cloth 2, bentonite bed 3 and second layer of cloth 4 of the dual waterproof blanket of overlay film swell soil of the utility model can be separate, pile up during use, and preferably, said bentonite bed 3 is fixed between said first layer of cloth 2 and said second layer of cloth 4.For example, said bentonite bed 3 is fixed between said first layer of cloth 2 and said second layer of cloth 4 through needling process.In the specific embodiment of the utility model, said nonwoven layer and said base fabric periphery sew, and said bentonite bed 3 is encapsulated between said nonwoven layer and the said base fabric.
Said bentonite bed 3 can have any structure, and in the specific embodiment of the utility model, said bentonite bed 3 is piled up by the sodium bentonite particle and forms.
The particle size of said sodium bentonite particle can confirm as required that in the specific embodiment of the utility model, the particle size of said sodium bentonite particle is not more than 32mm.
