Tunnels for reclaim. Depending on the configuration of the dome, the amount of material stored there, and how much product will be reclaimed an hour, the appropriate number of tunnels will be installed. Tunnels construction is determined early and is integrated into the dome's foundation.
This Super•Cor design with reinforced concrete collars was an economical alternative to conventional concrete tunnel designs. This reclaim tunnel, with spans of up to m (29′), is designed to support a stockpile height of m (87′) at T/m3.
The new tunnel will be used to reclaim material from a surge pile to feed the plant expansion. In order to meet these needs, a 5 gage, 10ft. diameter round MULTIPLATE ® structure was installed to accommodate a hopper/crab box feeder at the crown of the structure, allowing for it to accept stone and direct it onto a conveyor system.
This reclaim tunnel is used to mingle aggregate passed through a conveyor belt and loaded into delivery trucks The structure allowed for three points of entry to pass the aggregates onto the conveyor belt A concrete bottom was also poured to give a leveled path Hanson Material Service receives 2016New Reclaim Tunnel at Coal Fired Plant,Jul 10 ...
Superior Tunnel Reclaim. Maintain a continuous or on demand feed of material to your processing plant. Decrease your dependency on expensive loaders, fuel and operators. Modular design allows for future modifiions without replacing the entire system. Designed and manufactured for equal pressure across the tunnel's entire length.
The Reinforced Earth Company was approached to design and supply TechSpan® precast concrete tunnels for the reclaim conveyor and the emergency escape route to the new castinplace, reinforced concrete reclaim vault. The vault and tunnels were to be constructed in the middle of a very congested, fully operational, working mine facility.

May 22, 2015 · A special design was used to connect the beams to the concrete walls of the reclaim tunnel. The end connection design was similar to that used in bridge construction to reduce stress in the concrete connections due to thermal and mechanical loads on the beams. The support plates are rigidly fixed to the concrete walls of the tunnel.
