Retaining Wall

When the intended ground elevation exceeds the soil's angle of repose, retaining walls in Maple Ridge are utilised to hold the soil laterally so that it can maintain different elevations on both sides.

Here we will study retaining walls, their varieties and applications.

A retaining wall is a structure that holds soil.

Retaining walls can be concrete blocks, treated lumber, pebbles or boulders.

Backfill is the material that holds or supports a retaining wall.

The surcharge is the height of the backfill over the horizontal plane at the wall's top, and the surcharge angle is its inclination.

Retaining wall use:

This wall protects soil or other material from shifting suddenly.

Earth retaining structures keep the earth and preserve the ground surface height difference.

Other external loads are safely transmitted to a foundation by retaining structures.

Retaining Wall Types:

1. Gravity Retaining Wall: These walls resist lateral ground pressure only by their weight.

These retaining walls are required to counteract the enormous gravitational force.

These walls are made of concrete, stone, or masonry and are cost-effective up to 3 m.

Gravity retaining walls include crib, gabion, and bin walls.

2. Cradle Retaining Walls: These gravity walls are created from interconnecting wooden or precast concrete containers.

Soil is added to create a free-draining framework.

Precast and timber retaining walls are the most common

They are designed to sustain plains, not slopes or constructions.

 

 

 

 

The walls are multi-orbital, rectangular wire mesh packing containers loaded with pebbles or other materials

It is used to build erosion control structures and stabilise steep slopes.

4. Cantilever Retaining Wall: These walls are reinforced concrete, precast concrete, or prestressed concrete stem or base slabs.

These walls can be erected on-site or precast off-site up to 10 metres high.

The heel is the bottom slab piece under the backfill materials, and the toe is the reverse.

It uses less concrete than a gravity wall, but its design and construction are meticulous.

Its layout will also take into account sliding, reversing and bearing forces.

5. Counterfort retaining wall: Reinforced with monolithic behind the wall slab and foundation slab.

The counterfort wall is half the height of the counterfort.

The counterfort wall is 8–12 m high.

When the home is confined, or thin retaining walls are necessary, anchored retaining walls are used.

For loose soil atop rocks, use anchored retaining walls.

The ends of deep cable rods or wiring routes are filled with concrete to act as anchors.

Anchors (tiebacks) relieve pressure and prevent sliding.

7. Pile Retaining Wall: Made by mixing reinforced concrete piles.

They are pushed to a depth to sustain temporary and permanent pressure.

The pile provides extraordinary rigidity to the retaining walls, allowing them to dig deep without disturbing the neighbouring structures or properties.

Sheet pile walls are built using metal sheets to the desired slope or excavation, but they can't withstand very high pressures.

Maintaining the sheet pile to 6 metres.

8. MSE Retaining Wall:

This wall is the most common since it is cheap.

It is supported with granular fillers and reinforced with steel strips or plastic mesh.

The hybrid or composite retaining walls are employed in both masses and support stability.

Retaining Wall Benefits:

To protect a structure, retaining walls oppose gravity.

That is, they hold the dirt.

Producing value

Retaining walls protect your landscape from sinkholes.

They are used to level slopes and stabilise sloping terrain.

Best runoff:

Rainwater runoff can utterly destroy your property if it is not avoided.

This can protect your landscape design and keep floods out.

Reduce upkeep:

Retaining walls can help you protect your landscape design.

It protects against erosion and lowers upkeep.

Feature:

Retaining walls also enhance the aesthetics of your landscaping.

Retaining wall drawbacks:

Cracks in the wall:

Extreme pressure or temperature variations can cause vertical fissures in poured concrete retaining walls.

Fail-Safe:

Some retaining walls, like brick walls, cannot withstand severe soil pressure, resulting in brick breakage or foundation failure.

Termites:

When utilised as a retaining wall, wood might attract termites to your home.

Building a basement below ground level using retaining walls.

Wing walls and abutment work on the bridge.

To keep slopes in hills.

Bridge side walls approach roads.

Supporting the embankment's laterals.

CONCLUSION:

A retaining wall stabilises the soil and protects the buildings from flipping and sliding.
