REINFORCED CONCRETE COVERS FOR PRECAST MANHOLES
The precast reinforced concrete element are used to ease the access and to permit airing and ventilation of sewerages or waste systems; they are designed for the construction of manholes of up to 6 m depth in lawns, on streets and roads.
The A-15 type is designed to be fitted in parks, gardens, lawns, walkways and bicycle alleys.
1. Design
The use of the precast elements for precast manholes at each site should be according to an investment project, developed and approved in the respective legal manner, while observing the technical construction norms and the current harmonized European and Bulgarian standards. The designer is responsible for choosing the most suitable class of covers. In case of doubts, it would be better to choose the higher class.
2. Fitting
The fitting of these elements is done mechanically by two workers.
3. Use and maintenance
The precast elements for precast manholes do not require special maintenance, when the utilization conditions are the normal conditions for their intended use.
