How Do You Slurry A Concrete Wall?
How Do You Slurry A Concrete Wall?
A slurry wall is a civil engineering technology used to construct reinforced concrete barriers in soft earth near open water or locations with a high groundwater table.
This method is commonly used to construct diaphragm (water-blocking) walls around tunnels, open cuttings, and lay foundations.
Slurry walls are normally built by beginning with a series of concrete guide walls around 1 metre (3 ft 3 in) deep and 0.5 metres (1 feet 8 in) thick.
The guide walls are built close to the ground to define the required slurry trench and to direct the excavation machines.
Excavation is carried out with the help of a crane and a clamshell-shaped digger or a hydromill trench cutter.
The excavator drills down to the design depth (or bedrock) for the first wall segment.
The excavator is then raised and moved along the trench guide walls, allowing the trench to be extended with repeated cuts as needed.
The trench is always slurry to keep it from collapsing, but the liquid filling allows the excavation gear and spoils to be moved freely.
Once a certain length of the trench has been achieved, a reinforcing cage is dropped into the slurry-filled pit, and the pit is filled with concrete from the bottom up with tremie pipes.
The heavier concrete dispenses with the bentonite slurry, which is pumped out, filtered, and stored in tanks for use in the next wall segment or recycled.
Slurry walls are erected in stages to surround an area, preventing water and softened dirt from pouring into it.
After the concrete has cured, excavation can begin within the concrete-walled space.
Temporary supports, such as tiebacks or internal crossbeams, are added to prevent the concrete wall from falling into the freshly dug space. When finished, the structure within the walled-off section supports the wall, allowing tiebacks or another temporary bracing to be removed if desired.
How High Can A Fence Be On Top Of A Concrete Retaining Wall?
Are you looking for a way to keep your property secure? A high fence may be the answer for you. There are many types of fences to choose from, so it’s important to find one that is right for your needs.
One option is a surface mount fence. These fences are typically installed on top of a concrete retaining wall. They are often very high, allowing you to keep your property safe from trespassers.
However, most surface mount fences are limited in height to 3-4 feet. If you want a taller fence, you will need to use a bracket.
Bracket fences are a good option if you need a taller fence to keep your property safe from trespassers or if you want to keep your fence hidden.
Bracket fences are typically much stronger than surface mount fences. This means that they can support a much greater load. This is important if you use a bracket fence to protect your property from theft or damage.
If you are looking for a secure fence that is both high and strong, a bracket fence may be the right choice for you. You can find bracket fences in a variety of heights, so there is sure to be a fence that is perfect for your needs.
