Both the first half-cylinder 21 and the second half-cylinder 22 have water storage cavities 10. The first half-cylinder 21, the second half-cylinder 22, the conical teeth 4, the baffle 6, and the reinforcing ribs 11 are all made of high-strength metal.

The assembled cylinder 2 is placed into the mounting hole 3. At this time, the storage tanks 5 on the first half cylinder 21 and the second half cylinder 22 are spliced together to form a cylindrical storage chamber. Then, coolant is poured into the water storage chamber 10 in the first half cylinder 21 and the second half cylinder 22. Next, the prepared crushing agent is poured into the storage chamber. The crushing agent expands, causing the first half cylinder 21 and the second half cylinder 22 to separate and the medium 1 to break. When the crushing agent hydrates, it will generate a large amount of heat of hydration. The coolant in the water storage chamber 10 can be used for physical cooling, which can effectively avoid the occurrence of blowout phenomenon and prevent the high-temperature silent crushing agent from spraying out and injuring people, posing a great threat to the life and health of construction personnel.

[0021] By adopting the above technical solution, when the heat cannot be completely reduced by the coolant, a small amount of high-temperature blasting agent may be ejected. The baffle 6 in the storage tank 5 can block the high-temperature blasting agent when it is ejected, which can reduce the speed of the blasting agent. This will prevent the blasting agent from being ejected too high and the range from being too large. As a second protective measure, the baffle 6 can further increase the safety of static blasting.
[0022] Multiple conical teeth 4 are fixedly installed on the outer surfaces of both the first half-cylinder 21 and the second half-cylinder 22.
