Description
Technical Field
The utility model belongs to the technical field of the geotechnical material, concretely relates to high strength multilayer sodium bentonite waterproof blanket.
Background
A bentonite waterproof blanket (GCL) is an impervious liner between the CCL (in-situ thick compacted clay impervious liner) and the high molecular material, geomembrane. The sodium bentonite waterproof blanket is mainly applied to projects such as waste landfill sites, underground reservoirs, underground infrastructure construction and the like in the house basement' environment project, solves the problems of sealing, isolation and leakage prevention, is good in effect, is very wide in the market application field, but most of the internal structures of the sodium bentonite waterproof blanket in the current market are single-layer, low in strength, low in damage resistance and high in later maintenance cost.
Disclosure of Invention
The utility model aims at solving the defects and providing a high-strength multilayer sodium bentonite waterproof blanket.
In order to overcome the defect that exists among the background art, the utility model provides a technical scheme that its technical problem adopted is: the utility model provides a high strength multilayer sodium bentonite waterproof blanket, includes rubber soft layer, first sodium bentonite layer, base cloth layer, non-woven geotechnique's cloth layer and second sodium bentonite layer, rubber soft layer parcel is on the surface on first sodium bentonite layer, the lower extreme on first sodium bentonite layer is connected to the upper end on base cloth layer, the lower extreme on base cloth layer is connected to the upper end on non-woven geotechnique's cloth layer, the lower extreme on non-woven geotechnique's cloth layer is connected to the upper end on second sodium bentonite layer.
Preferably, the material of the soft rubber layer is polyurethane. The material has good elasticity, low cost and long service life.
Preferably, the base cloth layer is made of polypropylene woven cloth. The material has strong impact resistance and good stability.
Preferably, the material of the first sodium bentonite layer and the second sodium bentonite layer is sodium bentonite particles. The material has high water absorption and expansion times and remarkable waterproof and anti-seepage effects.
The utility model has the advantages that: simple structure adopts this technique can effectual improvement waterproof blanket's intensity and stability, and difficult tearing and damage have prolonged life cycle, have practiced thrift the cost, the effectual application field who enlarges the waterproof blanket of sodium bentonite, and the effect is showing.
