Maintenance shafts

The QuickTee™ maintenance shaft is a 600mm diameter vertical shaft for non-man entry to the sewerage system to introduce inspection (CCTV) and maintenance equipment. The shaft provides a complete system from base to finished surface level:

1. Effective heights from 1,035mm to 5,665mm.
2. A robust design for fast installation using ordinary backfill material and techniques.
3. The ability to accommodate traffic loadings and construction in roadways.
4. The provision of inline storage in the event of system surcharge.
5. High quality, high strength precast concrete for maximum service life.
6. Precisely engineered Humeseal® joints for watertight performance (tested to 90 kPa).
7. Optional 600mm access openings with a 300mm lid.
8. An innovative base design to ensure efficient hydraulic performance.
9. A small site footprint for installation in areas congested with other services.

The Humeseal® joint is a patented mechanical coupling system designed for fast, efficient and watertight jointing of UPVC pipe (100mm-225mm) into precast or in-situ structures. The joint will accommodate a 90 kPa pressure differential and remain watertight with up to 17° of angular deflection.
