Polyethylene manhole DN400

Sewer shafts are intended for installation on sewer lines as collection and distribution containers and as inspection openings when maintaining sewers systems. They are suitable for installation on walking and driving surfaces such as yards, sidewalks, parking lots and roads. The method of installation and construction of the shaft allow the approach to be easy and safe Construction and technology Inspection manholes made of polyethylene [PE] are made with the help of technology rotomoulding and are available in diameters DN 600, DN 800 and DN 1000 and different heights up to 5 m. They are distinguished by a long service life, waterproofness and resistance to various negative impacts. Due to their low weight (wall thickness 7 – 14 mm) there are inspection shafts easy to transport and manipulate on site. Different muld constructions allow connections with pipes of different types and manufacturers. The shaft is made in accordance with the standard SIST EN 13598-2: 2009, which determines the suitability shaft for impact resistance, circumferential stiffness, watertightness and load-bearing capacity of the shaft. Advantages The installation and connection of ROTO sewer shafts is easy and fast, that’s all thanks to technologically advanced and developed shaft shapes. It is made according to the requirements of the project and the client; shall be made at the appropriate heights and shapes with regard to the types and dimensions of connecting pipes. The DN400 sewer shaft with 1/1 mold is characterized by low weight and ease of installation. At the bottom of the shaft, there are prepared inlet and outlet connections with the possibility of connecting PVC pipes.
