manhole cover for circular well

Circular well cover Canzian, constructed using vibrocompression. 

Particularly suitable for sewerage, irrigation, and water collection applications, and where special attention to pipe sealing is required. This cover can connect structures of various materials and diameters. To ensure optimal flow even in low-water conditions, it features a channel design, composed of extension elements with connecting joints. For irrigation applications with large diameters, it can connect, using special inlets, external "U" channels with circular pipes and a siphon system. Without inlets, it is used as a sealed tank, while the extension elements alone can be used with the self-sinking technique for the construction of start and finish wells in NO-DIG excavations. The high level of technology used in this manufacturing process, combined with controlled quality concrete production, provides the manufacturer and user with the utmost assurance of product quality. This includes the ability to: 

- Automatically improve and control the concrete compactness, ensuring consistent production of manholes with a smooth internal and external finish. 

- Use special resins and cements in the case of aggressive water.
