Technical Field

[0001] The invention relates to the technical field of mining engineering, and in particular to a mechanical construction device for a caisson penetrating a rock layer in mining engineering. Background Art

[0002] Caisson construction is an underground structure construction method that first builds a shaft-like structure on the ground, and then gradually sinks it to the designed elevation under its own weight or external force. Caissons are often used in mining, water supply and drainage, and municipal engineering. With the increase in the depth of caissons in water supply and drainage and municipal engineering, the problem of caissons entering the rock has begun to appear in caisson engineering.

[0003] The existing mechanical construction equipment for caissons in mining projects that penetrate rock strata is very difficult to sink by relying solely on the deadweight of the shaft-like structure due to the hard rock, which reduces the efficiency of mechanical construction of caissons in mining projects that penetrate rock strata and cannot meet the needs of mechanical construction of caissons in mining projects.

[0004] Therefore, we propose a mechanical construction device for caisson through rock formations in mining engineering. Summary of the invention
