Retaining wall expansion joint detail.
Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together.
Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes.
Typical control joint detail figure 16.
Typical expansion joint detail backfill and drainage requirements.
Expansion joints should be located at intervals up to 90 feet.
8 2 types of joints in concrete walls 8 3 contraction joints 8 4 isolation or expansion joints 8 5 construction joints.
Chapter 9 liquid retaining structures p.
Precast concrete cantilever wall expansion joints shall be in accordance with the standard specifications section 6 11 3 3.
When the construction joint continues through the base like in the water tank the water bar shall be continued throughout the base also.
Chapter 10 mass concrete p.
These joints may be filled with flexible joint fillers.
For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on centers.
The joints permit free longitudinal movement and some also allow the transfer of lateral or out of plane shear loads.
