Super Precast Chamber

The junction piece of a drainage network, where U-drains, box culverts and Hume pipes meet, silt settles out and the line can be inspected.

Features

• One-piece chamber body: Four walls and the floor cast in one pour of SCC, no site shuttering.
• A lid that sits inside: The precast chequered lid drops into a seat inside the top, flush with the ground. Plain or perforated.
• Drains meet and turn here: U-drains and pipes enter through openings in the walls, straight on or turned through 90°; the joints are sealed in situ. Silt settles in the trap below.
• Silt trap: The chamber floor sits well below the drain, so silt settles here instead of in the line.

Applications

• Where U-drain runs meet and turn: T-25 runs enter on three sides, one straight on, one turned through 90°, through openings sealed with an in-situ mortar collar. Silt settles in the trap below the invert; the square cover lifts off for cleaning.
• Where the drains meet: Under the footpath and the road, the chamber joins the drain runs and gives access for cleaning.
• Plant yard drainage: A chamber at every change of line in the yard drain, silt stays out of the outfall.
• Cable & electrical chambers: Pull-pits for cables between trenches in a sub-station yard.

What it prevents

• Blocked, silted lines: Silt traps and access at every junction keep the line flowing.
• Leaking brick junctions: A monolithic chamber, joints sealed in situ.
• Slow site work: Lift in, connect, backfill, the same day.

Installation

1. Foundation: Crushed stone and PCC to level.
2. Place: Lower the chamber on its bed, square to the lines.
3. Connect: Enter the drain / pipe through the opening; seal with a cast-in-situ joint.
4. Cover: Set the frame and cover for the traffic class; backfill.
