Mould for producing non-prestressed precast concrete cones used as end sections for water conduits and to provide access to underground galleries. The eccentric profile transitions from a base with a 1,000 mm internal diameter to an offset top opening 597 mm in diameter. Each cone is 670 mm high and has an external diameter of 1,240 mm at the base.
A fixed core forms the inner surface of the cone, while two movable side panels shape the exterior. Mechanical clamps hold the panels together during casting. For demoulding, levers release the panels so they can be rolled apart by hand along guides on the base. The mould also features a removable polymer top cover and two independently controlled pneumatic vibrators, each operating at 16,000 vibrations per minute to compact the concrete.
