Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment technology, and in particular to a carbon dioxide blasting device. Background Technology

[0002] Carbon dioxide blasting refers to blasting technology that utilizes carbon dioxide phase change fracturing technology. It belongs to physical blasting technology and has the advantages of no exposed sparks during the blasting process, large blasting power, no need for blasting inspection, simple operation, and is not classified as a civilian explosive product. Its transportation, storage and use are exempt from approval. It is widely used in coal mining, blockage clearing and building demolition.

[0003] The existing carbon dioxide blasting process mainly involves drilling a hole first, then removing the drill bit and inserting a carbon dioxide blasting drill to carry out the blasting operation. In deep hole construction, the hole will collapse directly during the process of removing the drill bit, making it impossible to insert the carbon dioxide blasting drill into the hole, which seriously restricts the continuity of work and the reliability of blasting operations.

[0004] Therefore, it is urgent to research and develop a carbon dioxide explosion device to solve the above-mentioned technical problems. Summary of the Invention
