9 1 introduction 9 2 contraction joints 9 3 isolation or expansion joints 9 4 construction joints. True expansion joints in cast in place walls are not common. Due to the above reasons and many others several shear keys are provided over the cross sections. Chapter 9 liquid retaining structures p.

These joints may be filled with flexible joint fillers. Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes. 1 the bridge office has. Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated.

Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together. Precast concrete cantilever wall expansion joints shall be in accordance with the standard specifications section 6 11 3 3. 8 2 types of joints in concrete walls 8 3 contraction joints 8 4 isolation or expansion joints 8 5 construction joints. Backfilling against reinforced concrete retaining walls shall not be permitted until the concrete has reached its 28 day strength.

Thus we can check the stability. Typical expansion joint detail backfill and drainage requirements. 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.

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. Typical control joint detail figure 16. Construction joints use construction joints when the c o n c r ete placement.
