Technical Field

The invention belongs to the technical field of secondary blasting, and particularly relates to a comprehensive cooling and directional static blasting device.

Background

Demolition blasting is created in the context of clearing a two war legacy building. In the process of urban reconstruction and extension, the demolition blasting is paid attention to rapidly and simply, and occupies an important position in the demolition market. With the increasing sophistication of this technology and the significant economic benefits that it brings, demolition blasting has become one of the most competitive methods in the demolition industry.

Since 1936 U.S. scientist Lossier prepared chemically prestressed concrete by using the expansion effect of ettringite, the U.S. began to develop expanded concrete on a large scale. In 1958, Americans A. Claine successfully developed a sulphoaluminate cement, named K cement. In 1965-1972, calcium sulfoaluminate expanding agents were successfully developed in Japan. In 1970, the company of Japan and Xiao Yetian has also successfully developed a lime-based expanding agent. In the later 90 s of the 20 th century, the U.S. P.K. Mehta et al proposed the idea of incorporating 5% MgO in cement to solve the problem of temperature difference cracking of mass concrete, and thus developed magnesium oxide-based expanding agents. The expansion agent technology is developed relatively late in China, but the progress is fast. In 1979, the special book "compensated shrinkage concrete" was written by Wu Zhongwei academy, which is the first theory of compensated shrinkage concrete proposed by the scientific community of China. In 1985, under the guidance of Wuzhongweiji, the general research institute of building materials in China successfully developed concrete expanding agents of various types such as UEA, AEA and CEA. Thereafter, concrete expansive agents represented by experts such as nakah, cao yongkang, zhao shun zeng and liu li have been scientifically advanced into a new historical stage. The concrete expanding agent is widely applied to the branch fields of building construction, water conservancy, road traffic, nuclear power and the like, and brings great economic benefits to national production and construction.

The invention accompanying the static expanding agent has also led to a wide variety of blasting devices, most of which are used in the field of engineering blasting. There are many types of blasting devices, but the methods are almost the same in nature. Blasting generally adopts a physical method and a chemical method, wherein the physical method is to compress gas in a small space and release the gas in a substance needing blasting; and the chemical method is to use explosives. The corresponding blasting devices are various, such as a blasting cartridge, a blasting tank, a blasting pit blaster, a single-person bunker blaster, a rocket blaster and the like. Wherein, the blasting cartridge is mainly used for blasting city-building works and barriers; the blasting tank and the blasting pit blaster are mainly used for destroying roads, airport runways, armored workers and reinforced concrete workers, constructing anti-tank pits and the like; the single shelter blaster is mainly used for being carried by a single soldier and used for constructing a single shelter; rocket blasters are mainly used to open up pathways in obstacles. However, the conventional blasting apparatus using the expanding agent has problems such as: the safety problem is that the expanding agent is easy to generate a nozzle phenomenon, so that the safety of personnel is threatened; efficiency problems, the expanding agent takes several hours or more to perform the blasting action; the blasting direction is random completely; the problem of using the explosive is solved, and the traditional blasting explosive is wasted; the problem of limitation of use place, and the conventional blasting device cannot be used for the problem of lateral drilling blasting.
