I recently mentioned that crews completed a block retaining wall on the east end of the multi-use viaduct path. You might be surprised at how such a big, bulky structure requires delicate planning.
Our crews built a 67-foot long wall out of six tiers of precast concrete blocks. The blocks create and stabilize the transition from the edge of the south bank to the path. Retaining walls hold back tons of soil where there is a change in elevation. They displace the pressure of the soil that is naturally caused by loose soil.
As with most structural and load-bearing elements, many crucial factors aren’t visible to the common eye. When the team designed the wall, engineers addressed different soil properties, material settlement concerns and landslide resistance factors. Complying with the careful design, contractors installed a drainage pipe and used a permeable fabric to mitigate water pressure.
Construction of this retaining wall shows how attention to detail is crucial.
