What is Precast Concrete Retaining Wall?

Concrete retaining walls are structures designed to resist the breakdown of natural elements. Retaining walls provide structural support to maintain the Earth's lateral pressure. For example, concrete retaining walls can help rocks prevent erosion or prevent soil from falling off the slope. The architects have created many types of concrete retaining walls, including gravity, sheet piles, and cantilevered retaining walls, all of which can have a variety of textures.

 

gravity

Gravity concrete retaining walls are constructed using large stones or a large amount of precast concrete. These walls use the weight of the concrete wall to resist the pressure from each other. The short-gravity concrete retaining wall uses a dry stacking stone holder with a batter, which allows the wall to be tilted backwards towards the element being held.

 

For greater demand, precast concrete, geosynthetic materials, gabions, crib walls or soil nailed walls can be used to maintain. These walls are built taller and stronger by including reinforcement and rigid foundation applications. Reinforcements are usually used internally, including wood, soil, reinforced or polymer grid reinforcement.

 

masonry

When a block is used, such as a building brick or a block concrete wall, the structure is considered a masonry concrete retaining wall. Masonry retaining walls mean that masonry units (CMU block walls) are used to build walls. Masonry units are usually compressed soil blocks that are formed to a specific size and weight. With this unit, masonry walls can have equal resistance at all points on the structure.

 

Brick masonry concrete retaining walls use standard 8" x 4" x 2.25 "kiln bricks and mortars. The main disadvantage of brick masonry is that the bricks have a short service life and absorb a lot of water.

 

Block masonry retaining walls are also built to a specific size and weight. Due to their consistency in nature and their large concrete block sizes, concrete block walls can be built faster than brick retaining walls. They are also often reinforced with steel bars to increase the service life of retaining walls.

 

Sheet pile

Although it is usually the last option for concrete retaining walls, sheet pile walls are the most effective for soft soils and extremely narrow areas. Manufactured from steel, vinyl, fiberglass, plastic or wood panels, sheet pile walls must have at least two-thirds of the height of the walls pressed into the ground. The tall sheet pile wall needs a tether anchor “dead” in the soil
