Hard rock construction method
Air hammer type with directional control function for "shock drilling and propulsion method." The target soil types are infinite for gravel! Infinite for rock!
The hard rock construction method is a technique that uses a horizontal boring single-pipe propulsion system, incorporating large and small down-the-hole hammers into the leading body, allowing for the crushing of hard soil types such as soft rock, hard rock, gravel, and cobblestones while being propelled with low thrust. After the completion of the steel pipe propulsion, it can accommodate various pipelines (such as water supply and drainage, electricity, gas, and other lifeline pipelines). Additionally, as a special method, it is possible to construct pipelines with a nominal diameter of 800mm or more using a reaming method that utilizes the reach.
