In order to achieve the technical effects, the utility model adopts the following technical scheme:
the utility model provides a novel bentonite waterproof blanket, includes upper non-woven fabrics layer and lower floor's geotechnological cloth layer, upper non-woven fabrics layer periphery is fixed through sewing up the layer with the periphery on lower floor's geotechnological cloth layer, be provided with the bentonite filling layer between upper non-woven fabrics layer and the lower floor's geotechnological cloth layer, the both sides that upper non-woven fabrics layer and lower floor's geotechnological cloth layer are relative all are provided with overlap joint portion, overlap joint portion is including holding the bag, it has the bentonite filler to hold to fill in the bag, hold the bag with upper non-woven fabrics layer.
Further, the novel bentonite waterproof blanket is rectangular.
Furthermore, a plurality of anti-skid convex lines are uniformly arranged at the bottom of the lower geotechnical cloth at intervals.
Further, the containing bag is composed of thickened non-woven fabric, and the thickness ratio of the thickened non-woven fabric to the upper non-woven fabric layer is 1.2-2.0: 1.
further, the width of the lap joint part is 8cm-20 cm.
Further, the ratio of the thickness of the bentonite filler to the thickness of the bentonite filling layer is 1.5-3: 1.
compared with the prior art, the utility model provides a pair of novel waterproof blanket of bentonite's beneficial effect lies in: novel waterproof blanket of bentonite can improve effectively and simplify construction operation through setting up overlap joint portion, improves and lays efficiency, simultaneously, strengthens the prevention of seepage effect of adjacent waterproof blanket overlap joint of bentonite, and furtherly, through the bottom of lower floor's geotechnological cloth sets up the anti-skidding burr, can further strengthen the waterproof blanket of bentonite and the combining ability of ground avoid taking place the aversion phenomenon in laying process or use, lead to the overlap joint infiltration, can guarantee construction quality effectively, improve the efficiency of construction.
