Concrete Retaining Wall Expansion Joint Detail

Especially when the retaining walls is longer it can not be concrete at once and by a single pour.

Concrete retaining wall expansion joint detail.

Backfilling against reinforced concrete retaining walls shall not be permitted until the concrete has reached its 28 day strength. These joints may be filled with flexible joint fillers. Due to the above reasons and many others several shear keys are provided over the cross sections. Typical expansion joint detail backfill and drainage requirements.

9 1 introduction 9 2 contraction joints 9 3 isolation or expansion joints 9 4 construction joints. Chapter 10 mass concrete p. Construction joints use construction joints when the c o n c r ete placement. Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated.

Retaining walls and traffic barrier details for reinforced concrete retaining walls are. Thus we can check the stability. True expansion joints in cast in place walls are not common. For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on.

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. Ment should not pass through wall expansion or isolation joints. Chapter 9 liquid retaining structures p.

1 the bridge office has. Typical control joint detail figure 16. Expansion joints should be located at intervals up to 90 feet.
