Abstract

The invention discloses a dust settling water bag for blasting demolition of buildings, which consists of slurry, a blasting device and a blasting-proof water bag. Raw materials of the slurry include, by weight, 96-98kg of water and 2-4kg of dust adhesive. Raw materials of the dust adhesive include, by weight, 1.0-2.2 kg of cohesive soil, 0.3-0.5kg of binder, 0.3-0.5kg of sodium alcohol ether sulphate and 0.4-0.8 kg of table salt. The production steps of the dust settling water bag for blasting demolition of buildings include of preparing the dust adhesive by mixing the cohesive soil, the binder, the sodium alcohol ether sulphate and the table salt, preparing the slurry by adding water into the dust adhesive and uniformly stirring the same, producing the blasting device by inserting a detonator into 75-100g waterproof stick explosive, pouring 50-80kg of the slurry into the blasting-proof water bag, arranging the blasting device into the center of the blasting-proof water bag, thereby producing the dust settling water bag for blasting demolition of buildings. The dust settling water bag effectively solves the difficult problem that dust generated in blasting demolition of buildings flies anywhere in air, is low in cost and convenient in product and use and has the dust settling efficiency higher than 95%.

Description

technical field [0001] The invention belongs to the technical field of building blasting demolition, and in particular relates to explosive equipment for building blasting demolition. Background technique [0002] At present, the controlled demolition and blasting technology of urban buildings is an important means of demolishing tall buildings and structures. The environment of controlled demolition and blasting of urban buildings and structures is relatively complicated, and they are generally located in downtown areas, where people and other buildings are densely populated, which is harmful to safety and environmental protection. Strict requirements. The safety issues involved in the demolition blasting of urban buildings and structures mainly include controlling the direction and scope of the blasting collapse, controlling the distance of the blasting flying rocks and the intensity of the blasting seismic effect. Issues related to environmental protection are mainly to ...
