Retaining Wall Steel Reinforcement
Concrete cantilever retaining wall.
Retaining wall steel reinforcement. The heel is the part of the base under the backfill. It is constructed of reinforced portland cement concrete pcc was the predominant type of rigid retaining wall used from about the 1920s to 1970s. Allan block masonry walls are useful on sites where geogrids are not feasible or cost effective because they rely on a reinforced footing and vertical pilasters to counteract lateral earth pressures. Reinforced retaining walls reinforced concrete and reinforced masonry walls on spread foundations are gravity structures in which the stability against overturning is provided by the weight of the wall and reinforcement bars in the wall.
Earth slopes and earth retaining structures are used to maintain two different ground surface elevations. These walls cantilever loads like a beam to a large structural footing converting horizontal pressures from behind the wall to vertical pressures on the ground below. Cantilever retaining walls made of steel reinforced or cast in place concrete are connected to a slab foundation in the shape of an inverted t or l which allows horizontal pressures from behind the wall to be converted to vertical pressures on the ground below. Typical retaining wall section allan block retaining walls can be reinforced with the same proven techniques used for conventional masonry walls.
Types of reinforced concrete retaining walls are cantilever retaining walls and counterfort retaining walls. The base is divided into two parts the heel and toe. Construction sequence animation showing the reinforcement arrangement for a single retaining wall panel. Functions and parts of these retaining walls are discussed.
Reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab. Cut the vertical reinforcement steel bars for the lower storey so that they are flush with the top of that wall. Cantilevered retaining walls are made from an internal stem of steel reinforced cast in place concrete or mortared masonry often in the shape of an inverted t. The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
Shortly after pouring the concrete wet set additional vertical reinforcing bars also known as dowels into the concrete. The following are the main types of wall.
