The utility model embodiment provides a kind of carbon dioxide blasting arrangement, its is simple and reasonable, adds easy to manufacture
Work, is installed with easy to use, meanwhile, when carrying out rocky stratum excavation of foundation pit using the carbon dioxide blasting arrangement, it can improve
The efficiency of rocky stratum excavation of foundation pit, and have the advantages that to shake during its explosion and faint surrounding enviroment are influenced with small, risk is small, energy
Enough ensure the realization of metro station construction engineering objective duration.
Carbon dioxide blasting arrangement provided in this embodiment, by the way that the structure of blasting cartridge is improved, during practical operation,
Start the ignition component in blasting cartridge, expand the liquid carbon dioxide transient evaporation in blasting cartridge, the internal pressure of blasting cartridge
It is rapid to increase, while rupture disk is risen brokenly, high pressure draught is discharged from carbon dioxide outlet, realizes the purpose of explosion.High pressure draught
In flow process, high pressure draught is quickly entered to diversion cavity after breaking through rupture disk from storage chamber, since the inner wall of diversion cavity is
Taper surface, one end is big, one end is small, and high pressure draught flows to portlet at large port, and since cavity diminishes, high pressure draught, which flows through, leads
Speed when flowing chamber is accelerated, and fast from the speed of the high pressure draught of carbon dioxide outlet discharge, the time is shorter, more efficient to realize
Explosion, and force of explosion is more concentrated, demolition effect is good, and the success rate of explosion is high, reduces the influence to surrounding enviroment.
