Our Trenchless Services at Work:
Microtunneling in Soft Soils, Louisiana
A 72-inch diameter, 700-foot long microtunnel installation was successfully completed in early 2022, providing private, pressurized, utility conveyance under a combination Union Pacific Railroad and Burlington Northern Santa Fe rail yard. A total of 14 active railroad tracks, a rail yard, and a Louisiana Department of Transportation Highway were crossed with the tunnel installation. Ground conditions at the site consisted of 65 feet of very soft to soft clays, unerlain by a pressurized sand aquifer. Microtunnel construction was successfullly completed despite challenging subsurface conditions including soft, plastic clays difficult to process and steer the microtunnel machine through and driven wooden piles encountered periodically during tunneling.

Yadkin Regional Water Supply Project – Raw Water Infrastructure Intake
Huxted Trenchless installed 300 LF of 54 inch welded steel pipe via microtunnel for a new water intake structure. The project was performed in mixed ground of partially weathered rock and clay and included an underwater retrieval of the MTBM within Lake Tillery.

Stiles Vortex Outfall
For this microtunneling project, Huxted installed 250 ft of 84 inch RCP with an underwater machine recovery in the Mississippi river for a new waste water outfall. Ground conditions included sand and silt. The machine was launched from a 24 ft diameter shaft 60 feet deep.

84” UTILITY CONDUIT INSTALLATION
This microtunneling project involved a 580 foot Installation of 101.5 inch OD Reinforced Concrete Pipe in a 700 foot radius curve at a depth of over 50 feet by Microtunneling. Soil consisted of sandy silt with gravel. A VMT Guidance and Jack Control System were used to provide guidance and control of the curved alignment. Surveyed results were within ½ inch of design grade and line. Due to the location of this microtunneling project, security constraints required the tunnel to be constructed inside two separate buildings. One building housed the separation plant and the other housed the launching shaft and pipe storage.

CATAWBA RIVER STEELE CREEK FORCE MAIN
Huxted Trenchless was contracted to complete the Catawba River Steele Creek Force Main project.
The project consisted of a 1,305 foot trenchless crossing via horizontal directional drill under the Catawba River for the installation of 30” DR11 HDPE pipe that will serve as a sewer force main. The project helped to connect the growing populations of York County and the town of Fort Mill with the Rock Hill Wastewater Treatment Plant.
The crew overcame numerous challenges including difficult ground conditions consisting of cobbles, boulders, and solid rock with strengths of up to 30,000 PSI to complete the project in just 37 days.
