Jacking Pipes

Jacking pipes for microtunnelling are made of reinforced concrete. They often come with invert channels to contain the dry weather flow and are manufactured either in a dry-cast or a wet-cast process (see table on the following page). During wet-casting, the concrete is left to harden in the mould. This technique is currently considered state-of-the-art in pipe manufacturing and is particularly suitable for projects with high demands on both dimensional accuracy and surface quality. Reinforced jacking pipes offer many advantages: they are extremely robust, structural loads can be calculated, they are designed to withstand heavy loads, and they are characterised by high dimensional stability.

Furthermore, they are highly resistant to abrasion and highly durable, with a service life of more than a hundred years. Upon your request, HABA-BETON will also manufacture jacking pipes of ultra high performance concrete or supply pipes with partial or full linings such as HDPE liners to ensure maximum resistance to mechanical and chemical exposure from the inside and the outside.

Apart from jacking pipes, our product range also includes lead and end pipes as well as intermediate jacking stations. In addition, our comprehensive delivery programme is complemented by customised special components such as tangential manholes, bends and intermediate/reducing units.

HABA-BETON manufactures state-of-the-art jacking pipes and caisson sinking shafts.

1 Economical
FBS concrete and reinforced concrete pipes are made of natural raw materials which are locally available anywhere (node - pendence on imports or lack of resources).

2 Durable
FBS pipes have a service life of more than a hundred years.

3 Easily calculable
FBS concrete pipes are dimensionally stable and can be designed for all possible structural/load requirements and installation conditions.

4 Resistant to high-pressure flushing
FBS concrete and reinforced concrete pipes are highly robust and withstand flushing pressures of up to 300 bar.

5 Stable and non-floating
Due to their weight, there is no danger that the pipes will float or move during heavy rainfall or as a result of rising groundwater levels.

6 Versatile
T he pipes can be produced in a large variety of nominal sizes, shapes and pipe lengths as well as for any load case.

7 Ecologically viable
FBS concrete and reinforced concrete pipes are produced of natural raw materials, facilitating energy efficient production methods and recycling.

8 Abrasion resistant
T he material structure and the wall thickness allow for high flow rates and ensure that high amounts of sand can be transported.

9 Corrosion resistant
The pipes are suitable for draining communal wastewater and are resistant to solvents, cleaning agents and petroleum.

10 Hydraulically efficient
Smooth wall surfaces (roughness values < 0.1mm) enable free flow without deposits.

11 Temperature resistant
FBS concrete pipes are resistant to high temperatures and flammable liquids.

12 Watertight
Watertightness is essential for all concrete pipes.
