Description

Technical Field

[0001] The utility model belongs to the technical field of composite waterproof blanket construction, in particular to a groove wall adaptive widening and extruding device for overlapping composite waterproof blankets. Background Art

[0002] Bentonite composite waterproof blanket (GCL) is a new type of geosynthetics. It is made of graded natural sodium-based bentonite particles and corresponding admixtures as raw materials. The bentonite particles are fixed between geotextiles and plastic woven fabrics through needle punching technology and equipment to form a blanket-like waterproof roll. The GCL composite vertical anti-seepage barrier technology is to lay GCL composite components vertically along one side of the trench wall after excavation, and then backfill the trench with low-permeability reactive wall materials to build a composite underground continuous wall structure with anti-fouling and anti-seepage functions. Because the surface of the GCL material itself is rough and porous, it can be closely integrated with the wall material to form an overall anti-seepage structure.

[0003] However, in actual construction, if the geotextile cannot fit fully with the trench side wall, or the geotextile cannot be sealed at the GCL overlap, it will become a concentrated seepage channel after the project is completed, which will have a great impact on the anti-seepage project.
