AI Technical Summary
Technical Problem
In existing technologies, when underwater rock plug blasting is performed, the explosive tube is pressed tightly against the lower edge of the borehole wall, causing eccentricity and affecting the blasting effect.
Method used
The explosive tube is composed of multiple segments connected by arc-shaped connecting pieces. The arc-shaped connecting pieces can deform elastically. The restraining sleeve restricts the outer diameter of the explosive tube. After being inserted into the borehole, the restraining sleeve is removed to allow the explosive tube to expand, thus achieving automatic centering of the explosive.
Benefits of technology
Ensure the explosive is centered accurately, avoid eccentricity, and improve the blasting effect to meet design expectations.
