Technical Field
[0001] The utility model relates to the technical field of drilling and blasting devices, in particular to a local blasting buffer structure for preventing damage to a blasthole base. Background Art
[0002] Drilling and blasting refers to the method of excavating rocks by drilling, charging, and blasting, referred to as drilling and blasting. Drilling and blasting has always been the main construction method for rock excavation in underground buildings. This method has strong adaptability to rock geological conditions and low excavation costs, and is especially suitable for cavern construction with hard rocks. In the work of drilling and blasting, a gun barrel is often required to fill the gunpowder, so as to blast the explosives.
[0003] However, during the use of existing blasting barrels, the base of the barrel often breaks due to excessive use of gunpowder, which leads to a significant decrease in blasting power, thereby affecting the efficiency of the blasting work.
[0004] Therefore, we proposed a local blasting buffer structure for preventing damage to the blasthole base in order to solve the above-mentioned problems. Utility Model Content
