Engineer shovel is also known as engineer shovel. In history, the People's Liberation Army first used shovels on a large scale for military purposes in the three major battles. Before that, they were fighting guerrillas. After liberation and due to historical reasons, the Republic used military strategies such as preparing for war and preparing for famine, digging deep holes and accumulating grain, etc., and carried out a large number of underground bunker construction projects. It was from then on that the engineering shovel was officially included in our army’s military use. equipment category.
A generation of military engineering shovels evolved from shovels, which were born to meet the needs of survival. Soldiers found that the wooden handles of ordinary shovels were too long, difficult to carry, and easily exposed targets, so they sawed the wooden handles short.
The birth of the second-generation shovel is largely based on reference to the Soviet Army’s engineering shovel. Simply put, it can be folded once, and the handle is changed to a triangular-like streamlined shape based on mechanical principles.
The third-generation shovel is improved to be folded twice, and the handle is still triangular and streamlined. It has the functions of shovel, pick, crowbar (thorn), saw, and knife. In terms of production technology, the first-generation shovel uses high-quality steel, but I personally think The last two generations of shovel technology have not changed much, and both use high-quality quenched high-carbon steel to increase strength, wear resistan
