Outflow elements for bank reinforcement
To create an overflow in an open reservoir or retention basin, DWTN offers a selection of various outflow structures. These ready-made prefabricated elements ensure durable and elegant bank reinforcement. If desired, they are factory-fitted with a check valve and galvanized protective grid.
Depending on the desired pipe connection, we distinguish five types of outlet basins for connecting various diameters of concrete or plastic pipes. Each type can be produced in four different slopes: 1:1, 2:3, 1:2, and 1:3. This allows the sidewall to always follow the slope or embankment.
Depending on the chosen slope, the floor slab will also be adjusted. Connection options include a slip seal for the concrete pipe, a cast-in PVC sleeve, or a generous recess. The latter allows for the desired pipe to be poured on-site. Each type is equipped with traditional reinforcement, four ball-end anchors, and beveled edges on the visible sides. Furthermore, they have a perfectly smooth finish. They are made of self-compacting concrete with HSR cement and are cast monolithically. Our outflow elements are BENOR and NL BSB -approved. This makes them suitable for both the Belgian and Dutch markets.
Of course, it is always possible to produce these products according to the project requirements within our customization department.
