Prolunga rettangolare armata

The use of the reinforced rectangular manhole, produced through an automatic manufacturing process with vibro-compression and controlled feed, is particularly suitable for sewage, irrigation, and water collection systems, as well as in all situations where special attention to pipeline sealing is required.

This manhole is capable of connecting structures made of different materials and diameters.

To ensure optimal flow even under low-water conditions, the base is shaped as a channel, composed of extension elements with a connecting joint.

In large-diameter irrigation systems, it can connect, through special inlets, external U-shaped channels with circular pipes and siphon systems.

When no inlets are provided, it can be used as a sealed tank, while the extension elements alone can be employed using the self-sinking technique for the construction of starting and arrival shafts in NO-DIG excavation systems.

The high technological level of this manufacturing process, combined with controlled-quality concrete production, provides both the manufacturer and the user with the highest assurance of product quality, offering the following advantages:

Automatic improvement and control of concrete compactness, ensuring constant production of manholes with a smooth internal and external finish.

The possibility of using special resins and cements in the presence of aggressive water conditions.
