Concrete Retaining Wall Expansion Joint Detail

Figure 12 for timber retaining walls and figure 13 for masonry and concrete retaining walls.

Concrete retaining wall expansion joint detail.

Since we know the cohesion of the concrete and the surface area of the joint resisting force can be calculated. Typical control joint detail figure 16. Control joints are typically required in exposed above grade concrete masonry walls where net aesthetic shrinkage cracking may detract from the appearance of the wall and to limit moisture or air infiltration. Thus we can check the stability.

Due to the above reasons and many others several shear keys are provided over the cross sections. 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. Backfill and drainage. Expansion joints also work as contraction joints and may have smooth dowels to maintain the plane of the wall.

9 1 introduction 9 2 contraction joints 9 3 isolation or expansion joints 9 4 construction joints. Vertical expansion joints are incorporated into the wall to account for expansion due to temperature changes. Greased steel dowels are often cast horizontally into the wall to tie adjacent sections together. Ment should not pass through wall expansion or isolation joints.

Expansion joints should be located at intervals up to 90 feet. Expansion joints that allow completely independent movement between adjoining components are sometimes called isolation joints. These joints may be filled with flexible joint fillers. Retaining walls and traffic barrier details for reinforced concrete retaining walls are.

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. Construction joints use construction joints when the c o n c r ete placement. 1 2 filler material.

True expansion joints in cast in place walls are not common. Backfill and drainage. Concrete expansion joint detail. Construction joints separate adjacent placements of concrete to make large pours manageable.

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. 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.
