“The Well” Diffuser
Design of underground diffuser; two ∅35′ diameter disk and 135 ft high. All shipped in small pieces to site and assembled with minimal welding.
About this Project
Downtown Toronto is heated and cooled with a thermal fluid. “The Well” allows the fluid to be stored as well as regulate or control the fluid temperture. It is located in a cavern beneath a high-rise building in Toronto.
The Diffuer’s are ∅35′ in diameter and 135 ft high with ∅24′ piping, all fabricated off site and bolted together in the cavern. Temperature reversed of up to 100° F.
1500+ bolts and only 2 holes had to be opened up. Assembly and installation took 2 weeks.
Modified tower crane sections supported the diffuser disks and additional and bracing to accommodate the lateral forces introduced by thermal expansion of the supply & return pipes. Objective Engineering designed unique horizontal bracing joints and connections to properly distribute the extra loads to prevent crushing of piping, maintain lateral stability and to easily install the bracing in a years’ time when the concrete walls will be placed.
An offload platform consisting of eight platforms, each with a load arm and gangway to connect to each railcar, seven walkways connecting the platforms, two fixed ladders and a main access stair.
Collaborative project to study and evaluate the effect of wear, environmental degradation and work environment on fall protection lanyard strength.
