The reinforced retaining wall is comprised of precast, concrete block masonry unit facing elements connected by suitable connectors to reinforcing members which extend from the facing elements into the adjacent reinforced soil to form a mechanically stabilized earthen wall construction. The connectors which...

[0003] One problem with the Jersey-style highway barriers described above is the weight of reinforced concrete. A concrete barrier having a typical length of twelve feet weighs about 2,800-3,200 pounds, and requires special equipment to load, unload and handle on site. It has been estimated...
Sometimes it is made of reinforced concrete. Steel bars are put in place first and are boxed in. Then concrete is poured around them. The concrete sets and makes a very strong frame. Huge cranes lift the girders or the steel bars into place as the building grows. They carry up wet ...
