Sewerage system
Prefabricated concrete inspection chambers for sewage systems are intended for the collection and drainage of waste and storm water, as well as for the maintenance, control and cleaning of the system.
We produce them in the classic way with a concrete bottom and with a plastic bottom that protects the cistern from the adverse chemical effects of sewage liquids. The required height of the manhole is obtained by using vertical extensions of the appropriate height and conical end or reinforced concrete plates onto which the cast iron cover is directly mounted.
All corners of the pipeline route are solved in the base of the manhole, concrete or plastic. Concrete manholes can have cascade connections at a height defined by the customer. All pipe connections, joints, seals and manhole construction are designed in a way that guarantees watertightness.
The table shows the dimensions of the window, the elements they consist of and the possible types of the window base:
| WINDOW NAME | MANHOLE DIMENSIONS (bright opening) | ELEMENTS THAT MAKE UP A WINDOW | BASE TYPE | MAXIMUM SIZE PIPE CONNECTION |
|---|---|---|---|---|

| CONCRETE PREFABRICATED INSPECTION MANHOLE KBS 800 | DN 800 mm | • DN800 base • AB vertical element DN800 • conical end DN800 or reinforced concrete plate DN800 | with concrete bottom with plastic bottom | DN 300 mm DN 300 mm |
| CONCRETE PREFABRICATED INSPECTION MANHOLE KBS 1000 | DN 1000 mm | • DN1000 base • AB vertical element DN1000 • conical end DN1000 or reinforced concrete plate DN1000 | with concrete bottom with plastic bottom | DN 600 mm DN 600 mm (thicker wall base) |
| CONCRETE PREFABRICATED INSPECTION MANHOLE KBS 1200 | DN 1200 mm | • DN1200 base • AB vertical element DN1200 • conical end DN1200 or reinforced concrete plate DN1200 | with concrete bottom with plastic bottom | DN 800 mm DN 800 mm |
| CONCRETE PREFABRICATED INSPECTION MANHOLE KBS 1500 | DN 1500 mm | • DN1500 base • reduction plate DN1000/1500 or DN1200/1500 • AB vertical element DN1000 or DN1200 • conical end DN1000 - DN1200 or reinforced concrete plate DN1000 - DN1200 | with concrete bottom with plastic bottom | DN 1200 mm DN 1000 mm |
Types of assembly manholes:
Depending on the connection requirements, the following types of inspection chambers are produced:
- Transient
- Transient (profile change)
- Angular (≤90°)
- Angular (≥90°)
- Initial (blind)
- Cascade
The window elements come with:
- rubber gaskets for connection
- plastic-coated climbing frames built into the shaft
- Plastic connectors integrated into the shaft base
- Plastic kinetoscope integrated in the base of the shaft
All component materials incorporated into the inspection chamber elements have appropriate declarations of conformity.
