Ground dragon rock horizontal directional drill
At present, the industry for the rock geological conditions of directional crossing, mainly using mud motor with a large number of mud construction methods. The mud motor is driven by high pressure mud, which results in the decrease of construction efficiency and the high construction cost.
"Ground dragon heavy machinery" as a responsible product manufacturer in the industry, has long recognized this problem. After continuous program optimization, a new type of "double-wall drill" was finally born.
The design scheme of the ground dragon double-wall rod drilling machine cuts off the traditional mud motor, and adopts the method that the drill machine directly drives the tooth wheel jacking through the inner drill pipe, which greatly improves the construction efficiency and greatly reduces the construction cost.
