Fields of application
SIMBA TEGRA 1000 provides easy access for inspection, cleaning and maintenance in sewer and drainage systems in non-traffic and traffic areas. The load bearing capacity on an installed manhole is 40 tons truckload.
Range
The Tegra 1000 manhole consists of three parts being the cone (top), the shaft and the base. The shaft is available in different heights, ranging from 125 mm to 1000 mm. The Tegra 1000 base is available in different flow profiles and suitable for pipe connections from 160 mm up to 400 mm. Shafts can be joined for increased heights.
The Tegra 1000 has spacious 600 mm or 640 mm entrance and diameter of 1000 mm. The manhole is supplied with an inside ladder and optional telescopic safety rod. There are cutting indications on the shaft every 12.5 cm, so that it can easily be cut to the required depth. Extra “in-situ” pipe connections can easily be made.
Flow Profiles
The Tegra 1000 base is available in 7 different flow profiles.
- Straight 180° 160, 200, 250, 315, 400 mm
- Bend 15° 200, 315 mm
- Bend 30° 200, 315 mm
- Bend 45° 200, 315 mm
- Bend 90° 200 mm
- Left and right junction 4 connection 160, 200, 315 mm
- Empty Base
Features and Benefits
♦ Completely plastic in HDPE
Corrosion resistant, durable.
♦ 90% Lighter than Concrete manhole
Therefore easy to handle and install.
♦ Resistant to heavy traffic Load
Up to 40 tons truckload.
♦ Simple and reliable in-situ connection possible
Additional connections can be made in the shaft.
♦ Lower installation costs
Due to the easy cutting of the shaft to the correct height, easy connection of extra pipes on the site and adjusting to the correct level.
♦ Completely tight
Due to the rubber ring sealing.
♦ Adjustable height
The shaft can easily be cut every 12.5 cm to adapt the manhole to the required installation depth.
♦ Variety of installation depths
By joining shafts, installation depths can range from 1 to 8 meters, with a maximum groundwater level of 5m.
♦ Smooth internal surface
Less slime build-up, minimizing the risk of blockages.
Easy to clean, low maintenance efforts required.
♦ Stable and durable
Due to the unique rib structure and shape.
♦Excellent chemical resistance
Tegra 1000 is made from PE, which is resistant to a great number of chemical agents.
Installation
- Prepare a suitable bedding layer.
- Place the Tegra 1000 manhole base into position and make all pipe connections.
- Apply lubricant to the rubber ring and place around the base.
- Apply lubricant to the shaft socket and bring it to the correct position by placing in line the ladder marks on the outside of the shafts.
- Clean carefully before placing the rubber ring in position at the next shaft section.
- Back fill and compact layer wise with granular material around the manhole.
