Reinforced cement concrete retaining wall cantilever type maximum 6 0 meter height including column load in line.
Reinforced concrete retaining wall construction.
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.
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.
Retaining wall retains earth when level difference exists between two surfaces.
In case of masonry retaining wall the thickness of wall increases with height because masonry resists the lateral pressure by its weight.
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.
Retaining wall can be built with masonry along with reinforced concrete.
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.
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.
They consist of a relatively thin stemand a base slab.
Retaining walls are utilized in the formation of basement under ground level wing walls of bridge and to preserve slopes in hilly terrain roads.
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.
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.
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.
The base is also divided into two parts the heeland toe.
The reinforced concrete retaining wall resists the lateral pressure by structural action such as bending and results in thinner section.
Cantilever retaining walls are constructed of reinforced concrete.
Thus it is also called gravity retaining wall.
