PE INSPECTION MANHOLES MADE WITH CORRUGATED PIPES BODY

BRIEF DESCRIPTION

Circular manhole, made of multiple polyethylene (PE) modules, with bases and manhole reductions provided with a socket to accommodate the connection of the extension body made of corrugated pipe. The base can be made with a single or double flat plate. The manhole is available in black colour, with a diameters range that goes from DN 630 up to 1200 mm, in order to allow the inspection of underground pipes which are accessible with DN ≥ 800 mm. The modules allow the creation of in-line manholes, vertex manholes, intersection manholes and backdrop manholes. Modules are preassembled at the factory before the shipment through an extrusion connection made by qualified personnel, but they can also be assembled partially or entirely on the construction site through specific sealing gaskets. The manholes used for inspections are provided with stairs (on request). Suitable for connecting all plastic pipes, but also the stoneware ones. Suitable for applications in areas subject to heavy traffic, combined with an uptight plate for force distribution, for heights of ≤ 5 m and groundwater heights of ≤ 2 m. The wide range of individual modules shapes allows to create various standard modules, but with customised versions too.
