Guided Auger Bore – Hoyles Lane

Project Overview
Following a detailed evaluation, Bethell Construction engaged Trenchless Solutions Limited (TSL) to
carry out a trenchless crossing at Hoyles Lane, Preston. The project was required to facilitate the
installation of sewer infrastructure beneath both a railway line and a canal, necessitating a no-dig
approach to avoid significant surface disruption and environmental impact.

Description of Works
After a detailed evaluation TSL was engaged by Bethell Construction to supply and install DN600
GRP jacking pipe using a guided auger bore method. The project involved the installation of 52
metres of DN600 pipe beneath Parkinson Lane Railway Line and a further 62 metres under
Lancaster Canal. Precise engineering and trenchless expertise ensured a successful installation,
minimizing surface disruption while achieving seamless connections to the existing infrastructure.

 

 

Proposed open cut construction	As built 5 week trenchless construction
Restricted access: Works beneath an active railway and a canal Limited access to launch and reception shafts	Restricted access: Minimal surface disturbance No canal or railway closures required
Health & safety: Deep excavation risks near live rail Confined working space and environmental hazards	Health & safety: Reduced risk to personnel working near live infrastructure Confined space procedures strictly managed
Cost savings: Significant costs related to reinstatement, track and canal closure Need for 24/7 possession monitoring and management	Cost savings: Eliminated need for track and canal shutdown Reduced surface restoration Lower operational time
Environmental: Disruption to sensitive infrastructure (canal and rail) Noise, dust, and CO2 associated with prolonged open-cut operations	Environmental: Preservation of existing surface conditions Reduced emissions, waste, and noise
