Embodiment 1

[0027] The construction method of overlapping bentonite waterproof blanket, the specific steps are as follows:

[0028] 1) Carry out basic treatment on the base of the waterproof construction site, such as tamping, leveling, compacting, etc. The treatment method of the base layer is as follows: there should be no linear flowing water on the surface of the floor cushion concrete and the surrounding protection piles, otherwise the leakage treatment should be done first; the cushion concrete should be calendered and smoothed while pouring to avoid large bulges and unevenness Parts; the protrusions on the surface of the retaining piles should be chiseled off, and the nets should be hung with shotcrete between the piles.

[0029] 2) Lay the bentonite waterproof blanket on the base layer by manual laying or mechanical laying. First lay the bentonite waterproof blanket at the yin and yang corners, and then lay the large bentonite waterproof blanket; the bentonite waterproof blanket ...

Abstract

The invention provides a construction method for the overlap joint of geosynthetic clay liners by using a photocuring technology. The method comprises the steps that water-soluble ultraviolet light curable resin and photoinitiator are sprayed on the surfaces of the geosynthetic clay liners in sequence, the photoinitiator is irradiated by using ultraviolet light to trigger the curing of the water-soluble ultraviolet light curable resin, and the overlap joint between the geosynthetic clay liners is achieved. The method is simple in technology and low in cost, the overlap joint can be achieved between the geosynthetic clay liners and other materials and among the geosynthetic clay liners in a construction process by using the photocuring resin, the overlap joint effect is good, and leakage does not occurs easily.

Description

technical field [0001] The invention belongs to the field of building waterproof and anti-seepage construction, and in particular relates to a construction method for lapping a bentonite waterproof blanket by utilizing the cohesiveness of a water-soluble photocurable resin. Background technique [0002] After years of development, my country's waterproof materials have hundreds of specifications and varieties. Especially in the past ten years, with the development of the waterproof material industry, new waterproof materials continue to appear. [0003] Bentonite waterproof blanket is a blanket-like material formed by fixing specific bentonite between two layers of geotextiles, also known as Geosynthetic Clay Liner (GCL for short), which has developed rapidly in recent years and has a unique New waterproof material with waterproof effect. The application of water-swellable bentonite as a waterproof material first began in the 1920s, when it was mainly used in the form of g...
