Drainforce Highgate Depot Channel Installation and UV Lining

Drainforce were tasked to rectify defective pipes on various gravity drains under London Underground Tracks at Highgate Depot for Skanska.

Due to the amount of root infestation the design was to install 105m of Channel drainage to aid future maintenance and to UV Line sections where excavations proved too difficult due to the above signals and tracks. Though Pre-Site Meetings and planning a Method Statement and Safe Working System was confirmed and signed off.

Before Works commenced Pre Site Meetings and Briefings were completed Daily ensuring the details of the Method Statements were filtered through and that Daily Dynamic Risk Assessments were completed monitoring Weather and any variable conditions.

Drainforce firstly cleaned the lines with their recyclers. After cleaning CCTV identified tap and mass roots. Due to the poor service condition of the drains further jetting would have caused more damage to the pipes and risk collapse.

Drainforce deployed their robotic cutter to Cut the roots in readiness for the UV Lining.

Once the Cutting and cleaning was complete Drainforce UV lined 5 sections of Drainage Runs down stream of the channel drainage installation.

Drainforce’s Civil Engineering division complete the Channel Drainage upstream of the UV lining simultaneously. The old Drainage pipe was dug out and catchpits removed. Geotextile was laid with shingle and ballast following a level line to the existing lined sections downstream. Due to the amount of staff on site and work activities shared site protocols were confirmed and agreed and a accurate program and method statement followed with regular updates.

Plant and Equipment

Drainforce Made use of its portable UV system to allow for a set up on Track distances to far away for the UV Rig to use. We also used our Main Line UV Mega Rig which has a 500m air-conditioned cable. This would not have been possible with Standard Equipment.

Track Trolleys and Excavators were used to install the Channel Drainage. All Equipment was less than 80dbs complying with Council noise regulations.
