In the accelerated development process of urbanization, trenchless directional drilling technology has been widely used in many fields, rocking drilling is more and more common. Traditional rock drilling technology is with high cost, low efficiency and high pollution factors, which puzzles the trenchless construction enterprises at home and abroad. On the basis of a large number of market research, with keen insight into the development direction of trenchless construction technique, a new type of horizontal directional drilling is developed---“GD450AT-LS Dual-wall Pipe rock drilling machine”. This HDD machine has come into market gloriously in June 2016.

GD450AT-LS Dual-wall Pipe rock drilling machine is developed on the basis of traditional trenchless drilling rig. and it is new horizontal directional drilling which apply to all strata of trenchless construction. It is new rock drilling technology whose drilling head is driven by outer pipe, and inner drill pipe drives roller bit to break rocks. Not only the drilling efficiency is greatly improved, but also the construction cost is significantly decreased. It will replace traditional rock drilling technology which is the combination of hdd machine and mud motor drive in the future. Besides the unique characteristics of Goodeng common hdd machine, GD450AT-LS Dual-wall Pipe rock drilling machine has the obvious advantage of "two high and one low", which is pioneering the new era of all terrain construction.

3.Low cost

GD450AT-LS Dual-wall Pipe rock drilling machine can drill and do the project without mud motor, which saves the expensive mud motor costs. Inner drill pipe drives roller bit, small amount of pump can easily break the rock, which can save a lot of mud costs. High efficiency can shorten the construction time greatly and save a lot of fuel and labor cost etc.
