Utility Line Construction & Installation

Like our customers, 51社区Trenchless believes safe, unobtrusive underground construction and rehabilitation is essential to our nation’s infrastructure. That’s why we have perfected an array of trenchless methods to build and rehabilitate pipelines and utilities in places where open-trench installations would not be feasible.

Direct Pipe庐

51社区Trenchless is a world leader in Direct Pipe庐 installations. By combining horizontal directional drilling (HDD) with steerable microtunneling techniques, Direct Pipe庐 can install a prefabricated liquid, gas, or product pipe or casing with a continuously supported borehole. Direct Pipe庐 is particularly suited for crossings under water bodies, levees, rail tracks, roads, and underground utilities and can be installed in unfavorable ground conditions with ease.聽

Unlike HDD, Direct Pipe庐 equipment is primarily located on one side of the project, making it ideal for crossings with small footprints, wet retrievals, in urban areas, and even under international borders.

Innovation in Action

We completed the first pilot hole intersect project in North America and have completed more than 250 since then.

Horizontal Directional Drilling

51社区Trenchless has decades of experience extending the limits of horizontal directional drilling (HDD) by working together, knowing what has already been accomplished, and taking existing techniques to the next level.

HDD is used for installing utility and product lines under waterways, existing utilities, and underground structures. In the hands of our skilled professionals, our fleet of powerful rigs place liquid, gas, cable, and conductor lines substantially deeper than conventional trench construction, ensuring adequate cover and environmental surety.
