Description

Technical Field

[0002] Earthwork blasting refers to a widely used construction method in which explosive materials such as explosives and detonators are used to blast earthwork in order to achieve the purpose of excavation during the construction of roads, bridges, mines, tunnels, water conservancy and hydropower projects, site leveling, foundation pits, bored piles, and pipeline trenches. In earthwork blasting projects, after the blasthole is loaded with explosives, the remaining blasthole section needs to be filled to fully utilize the energy of the explosives and reduce flying rocks.

[0003] At present, blasthole backfilling generally uses a funnel to introduce filling material into the blasthole. During the blasthole backfilling process, the backfill material in the backfill funnel is easy to block the discharge port, thereby affecting the normal backfilling operation of the backfill funnel and causing the blasthole to be not fully filled. This not only reduces the energy utilization rate of the explosives, but also easily causes punching and flying rocks, seriously affecting the safety of earth and rock blasting operations. For this reason, we have proposed a landfill equipment for earth and rock blasting. Utility Model Content
