Concrete Retaining Wall Expansion Joint Detail

Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes.

Concrete retaining wall expansion joint detail.

Retaining walls and traffic barrier details for reinforced concrete retaining walls are. If plans call for expansion joints verify the type of joint intended and execute the details carefully so the joint works pro p e r l y. Especially when the retaining walls is longer it can not be concrete at once and by a single pour. Precast concrete cantilever wall expansion joints shall be in accordance with the standard specifications section 6 11 3 3.

Backfilling against reinforced concrete retaining walls shall not be permitted until the concrete has reached its 28 day strength. Chapter 9 liquid retaining structures p. Construction joints use construction joints when the c o n c r ete placement. Typical expansion joint detail backfill and drainage requirements.

8 2 types of joints in concrete walls 8 3 contraction joints 8 4 isolation or expansion joints 8 5 construction joints. Due to the above reasons and many others several shear keys are provided over the cross sections. Typical control joint detail figure 16. Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together.

These joints may be filled with flexible joint fillers. Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated. For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on. True expansion joints in cast in place walls are not common.

Thus we can check the stability. 1 the bridge office has. Ment should not pass through wall expansion or isolation joints.
