We will perform propulsion by pressing in the steel pipe due to a large impact!
The "Grun Drum Method" is a construction method that uses a pneumatic propulsion machine powered by compressed air from a standard compressor. By utilizing the force of compressed air, the piston inside the Grun Drum strikes the main head, transmitting this impact force to the steel pipe, thereby enabling the propulsion of the steel pipe.

Company information
Our company was established as a gas piping contractor in 1976. As a result of actively addressing customer demands, we incorporated trenchless construction methods (jacking work) when burying pipes, which led to a reduction in civil engineering material costs and an overall acceleration of the construction process. Utilizing the technology we have accumulated in gas piping installation, we will continue to develop, equip, and construct a new groundwater-based heating and cooling system while considering the environment of various facility constructions.
