Retaining walls are rigid walls used to retain materials such as soil, water, and stones on one side to prevent them from collapsing or intruding into another side.
These walls work to retain the lateral pressure exerted by the retaining material from affecting the original structure.
As the proposed site has adjacent structures and developments on all 4 sides, the concrete pile retaining wall is the best choice. It also can be used as the basement walls with additional waterproofing features.
Characteristic:
Reduces the noise, vibration, and soil factors since it uses the same method as bored friction piles.
Can be called contiguous pile walls which act as retaining walls and the basement walls.
After excavation an additional wall reinforcement is added to the surface of piles and then shotcrete is done, or shotcrete is directly based on the soil and hydrostatic load on the wall.
Considering the site's location which is nearer to the water body and high-water table, an additional mesh or reinforcement along with shotcrete should be provided, creating a better basement wall with waterproofing.
Advantages
Creates less vibration
Provides a permanent retaining wall structure
Acts as basement walls as a better waterproofed structure
Doesn’t require additional excavation for the erection of contiguous piles.
Higher performance capability on areas with high water table.
