RCC PRECAST CONICAL AND RISER

Precast Manholes and Chambers with cover are available in cylindrical, conical and cuboid shapes have successfully replaced the old traditional manholes made from bricks which were time consuming and structurally weak for providing access to telecommunication infrastructure and sewerage system. Precast manholes and riser rings are produced using the latest vibro-compaction technique to ensure durability, high tensile strength and robustness.

The Precast RCC (M-40 grade) circular manholes with riser rings consists of conical piece on top with cover and circular riser rings made from precast reinforced concrete that can be stacked one on top of the other to construct the desired height of the manholes conical shaped manhole. At the end, circular bottom ring is attached consisting of desired number of holes of suitable diameter for line diversion and connectivity.
