Contractor uses trenchless for electrical duct installation

A contractor has used a TRACTO-TECHNIK mini horizontal directional drilling (HDD) rig to install electrical ducts in the UK.

Specialist Civil Engineering Contractor Rook Services recently completed the installation of 14 electrical ducts to provide power for new property developments under a major trunk road, the A38, in West Midlands, UK.

The project included working in limited space on either side of the road and tough soil conditions, and required compact technology that would not disrupt traffic.

The company elected to use a GRUNDOPIT 6V, provided by TRACTO-TECHNIK UK, with 1,375 mm by 1,100 mm by 1,440 mm dimensions.

Despite its small size, the rig had a powerful enough stroke to install pilot rods with an effective length of 750 mm.

Within just eight days, despite some site delays, twelve 110 mm ducts and two 160 mm ducts were laid, with Rooks completing drill shot lengths of 15–18 m/d.

“The [TRACTO-TECHNIK] team demonstrated excellent technical knowledge throughout this project,” said Rook Services Project Manager Nick Richards.

“A pre-site visit established the site requirements and pit dimensions, which led to an immediate start once the machine was delivered to site.

“Without doubt the GRUNDOPIT 6V is the ideal piece of equipment for this job.

“The ability to steer the drill within the tight space, underneath key infrastructure assets, meant we could complete the task safely and to the demanding specification of the customer.”
