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.

Concrete retaining wall expansion joint detail.

Typical control joint detail figure 16. Ment should not pass through wall expansion or isolation joints. Especially when the retaining walls is longer it can not be concrete at once and by a single pour. Construction joints use construction joints when the c o n c r ete placement.

8 2 types of joints in concrete walls 8 3 contraction joints 8 4 isolation or expansion joints 8 5 construction joints. Chapter 10 mass concrete p. Expansion joints should be located at intervals up to 90 feet. These joints may be filled with flexible joint fillers.

Typical expansion joint detail backfill and drainage requirements. For cantilevered and gravity walls vertical expansion joint spacing shall be a maximum of 60 feet on. Due to the above reasons and many others several shear keys are provided over the cross sections. Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated.

True expansion joints in cast in place walls are not common. 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. Precast concrete cantilever wall expansion joints shall be in accordance with the standard specifications section 6 11 3 3.

9 1 introduction 9 2 contraction joints 9 3 isolation or expansion joints 9 4 construction joints. Chapter 9 liquid retaining structures p. Thus we can check the stability.
