Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, and more specifically, to a peripheral eye charging structure for concentrated energy water pressure smooth surface blasting. Background Art

[0002] With the rapid economic development and the continuous development of road construction, the construction of subways and tunnels is also ongoing. In engineering blasting, conventional smooth blasting is currently used. Smooth blasting technology is the most critical process for controlling over-excavation and under-excavation of tunnels, protecting the surrounding rock of tunnels to reduce safety risks, and improving the quality of tunnel excavation profiles. The most critical technology in smooth blasting is the charge amount and charge structure of the surrounding eyes.

[0003] However, some existing charging structures easily cause poor sealing of peripheral eye blastholes, resulting in the entire charging structure not being fully sealed and serious energy loss of explosives. Therefore, in order to solve the above problems, a peripheral eye charging structure for concentrated energy water pressure smooth blasting is proposed. Utility Model Content

At the same time, through the cooperation of the threaded rod 301, the threaded barrel 202 and the top plate 3, the filler in the cartridge 1 can be squeezed, multiple fillers can be closely fitted, and the gap between the cartridge 1 can be reduced. At the same time, under the action of the first circular water bag 6a and the second circular water bag 6b, a "water wedge" effect will be generated when the explosive explodes, which is beneficial to the further crushing of the surrounding rock, can reduce the rate of large blocks produced by blasting, and can also reduce the dust concentration after blasting, thereby reducing the pollution to the environment after the explosion.
