Problems solved by technology

The traditional blasting demolition of brick-concrete buildings is usually demolished by drilling and blasting, which has the disadvantages of large number of blast holes, heavy drilling workload, and difficult control of blasting harmful effects (explosion shock waves, flying stones, noise and dust, etc.)
In order to overcome the shortcomings of drilling and blasting demolition of brick-concrete buildings, blasting technicians introduced hydraulic blasting into the demolition project of brick-concrete buildings, and used brick pools to form water storage containers. The disadvantages of large load, high safety risk, poor waterproof performance, long construction period and high cost greatly reduce the advantages of hydraulic blasting demolition method

Abstract

The invention discloses a water pressure blasting demolition device and a brick-and-concrete structure building water pressure blasting demolition method thereof. The device comprises a water storage container and a water storage container framework, the water storage container is fixed into the water storage container framework and tightly attached to the water storage container framework, the water storage container framework is provided with a cartridge bag locator, the cartridge bag locator is provided with a cartridge bag, the cartridge bag locator is arranged in the water storage container, and the water storage container framework is fixed to the back of a wall to be dismantled through a framework fixing piece. The water pressure blasting demolition device is high in strength, low in weight, low in cost, convenient and fast to construct and capable of saving energy and protecting the environment and is adopted for the novel brick-and-concrete structure building water pressure blasting demolition method.

Description

technical field [0001] The invention belongs to the technical field of engineering blasting, and in particular relates to a hydraulic blasting demolition device and a hydraulic blasting demolition method for a brick-concrete structure building. Background technique [0002] As my country's urbanization process and urban renewal speed continue to accelerate, the brick-concrete buildings built in the early days of major cities can no longer meet the living needs of more and more urban populations, and their demolition and reconstruction have become an inevitable solution to the housing needs of urban residents. choose. At present, the common demolition methods include manual demolition, mechanical demolition and blasting demolition. Compared with manual and mechanical demolition and other demolition methods, blasting demolition method has the advantages of safety, efficiency and economy, so it is widely used in demolition projects . [0003] Common blasting demolition methods...
