Reinforced Concrete Retaining Wall Construction

In this video lecture i show you how we construct the retaining wall at sit what type of bar was to be use it is very important to understand so check. 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. In case of masonry retaining wall the thickness of wall increases with height because masonry resists the lateral pressure by its weight.

Retaining wall can be built with masonry along with reinforced concrete.

Reinforced concrete retaining wall construction.

It is constructed of reinforced portland cement concrete pcc was the predominant type of rigid retaining wall used from about the 1920s to 1970s. The base is also divided into two parts the heeland toe. Retaining wall retains earth when level difference exists between two surfaces. Retaining walls are utilized in the formation of basement under ground level wing walls of bridge and to preserve slopes in hilly terrain roads.

Reinforced cement concrete retaining wall cantilever type maximum 6 0 meter height including column load in line. The heel is the part of the base under the backfill. Thus it is also called gravity retaining wall. Reinforced cement concrete retaining wall cantilever type information.

They consist of a relatively thin stemand a base slab. Retaining walls type 1 1a 5 and 6 crib walls made of reinforced concrete or steel ers that appear as bridge standard details are retaining walls type 7 modified retaining walls supporting sound walls type 1sw series and type 5sw series and type 7sw series mechanically stabilized embankment mse. 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. Reinforced concrete would not be developed for a thousand years but they used what they had and learned how to do it better with each succeeding structure.

Earth slopes and earth retaining structures are used to maintain two different ground surface elevations. Cantilever retaining walls are constructed of reinforced concrete. A gravity wall h 3m masonry or stone b cantilever wall h 3m and h 6m c counterfort wall h 8m d buttress wall transverse stem support provided on front side e e bridge abutment additional horizontal restraint from bridge deck a gravity wall h 3m masonry or stone. The reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section.

Consider the great wall of china for example where transverse bamboo poles were used to tie the walls together a forerunner of today s mechanically stabilized earth. Cantilever retaining wall is the most common type of earth retaining structure.
