Steel Pilings -- Design Foundation, Advantages and Disadvantages    

March 21, 2021

What are Steel Piles?

You can also refer to STEEL PILINGS as a section of steel rolled into a made-up shape or a sheet.  STEEL PILINGS can act as an interconnection between two sheets to come together as a box shape. They can form a single pile of too large loads.

The most advantageous factor behind using a steel pile is that it is able to carry a large capacity of loads. Approximately STEEL PILINGS can carry up to 100 tons of weight.  They are the most feasible choice when you want to lay the foundation of any structure that requires handling heavy loads.

Advantages of Using STEEL PILINGS

There are many advantages associated with the use of steel pilings. Many companies invest heavily in them for different reasons.  Especially, those companies working on making large structures incorporate steel piles for study build. It further eases the work for the engineering teams.

They have the capacity to bear large amounts of load. This helps in supporting vast structural challenges. Another distinguishing feature is that they can pass through tough layers and even boulders.  When driving steel piles, the amount of soil expatriate is very minimal.  Due to their study qualities, they can bear rough handling without getting damaged.

Disadvantages of Using STEEL PILINGS

Although using steel pilings has some major advantageous features, they come with a few disadvantages as well.  Moreover, having a sturdy build is not enough when making up a structure.

Steel piles are in great danger of undergoing corrosion. They are most likely to suffer from the damages caused by electrolysis. Unfortunately, Steel piling can accumulate to become very expensive except in cases where the upper layer can develop the capacity for a big pile.  On the other hand, when compared with friction piles, steel piles can be less efficient.

Common types of steel Piles

Steel Piles are available in many options. But the most common ones include H-piles and pipe piles.  These are the most used kind of piles during construction and functions related to construction.

What are H-piles?

H-piles are in the form of partitions or divisions. During rash and hard-driving, they are able to endure huge amounts of stress. The projections and the mesh of the H-piles are trundled using the same thickness for achieving evenness. This helps in eradicating any harm that might take place on the diluted parts of the piles.  The width of the projection needs to follow the set criteria of having at least 85% depth for providing firmness in the weaker axis areas.

What are Pipe Piles?

The pipe pile is the unified and fused combination of pipes filled with concrete.  These driven piles can be closed-ended or open-ended. The open-ended piles help in achieving the desired depth so that the soil attached to the pipes washes out.

Furthermore, closed-ended piles make-up by fusing these driving points. These points attach with the tips of these piles. For use in large columns, the pipe piles must have a diameter that should reach at least 10 inches along with the depth and thickness in between the range of 5 and 16 inches.

When constructing, it is imperative to choose between open-ended and closed-ended steel piles. It totally depends on the condition of the soil that is available at the site.   Our observation tells us that using an open-ended pile is most feasible when digging in great depths. This way the cleaning and screening of the soil become easy during the progression of construction.

Moreover, if during the construction the desired depth is way far than the usual, and the machines are encountering some obstructions like boulders, then they can chop off some bits and pieces.

If they encounter even larger obstructions, then they can use pipes that have fixed diameters and remove the excess material by blasting. When the soil seems impure and it becomes impossible to clean the soil, the company can use closed-end pipes to avoid this situation.

Connection of steel piles

H-piles usually combined in the same way as steel columns do.  With the help of equipment that is available, and taking suggestions from the engineering team, these piles can spice together with the help of bolting and welding.

If the welded part locates above the surface of the ground or the above design needs to carry some complicated engineering design then the splice of steel pipe must act in resisting stresses that might arise due to such possibilities.

In normal conditions, when the design is not of much complexity, the amount of stress that a pile needs to suffer gets very less. When driving a pile, it can lose its shape when any impact takes place. This allows the pile to have a bending moment. It is necessary to design the piles in such a way that the pile resists the impact by allowing no bending moments. Only a pile having strength can avoid such a situation and is reasonable in the long run.

Corrosion in Steel Piles

When dealing with piles, corrosion can be very problematic.  In order to avoid the effects of corrosion, there are a few ways to protect these Steel pilings. The following will help in keeping steel piles as much safe as possible.

Additional Thickness

Many companies swear by this step. This method employs the use of added thickness in piles. They incorporate an added thickness. Usually, this thickness is 1 by 16th of an inch. This section adds to the strength of the pile.

To achieve this, the actual depth of the metal must reduce by 1 by 16th of an inch. With the help of computation, the pile must have the capacity to apply an added wall of steel into the file length for avoiding corrosion in places most likely to deal with rust.

Removal of corrosive soils

Another way of avoiding corrosion is by using non-corrosive soil. If the site has organic soil, cinder fills, un-burnt carbon, and industrial waste then it is imperative to replace this with soils that are non-corrosive. It is a very economical method when the site has a shallow quantity of soil.  But, otherwise, this can lead to very expensive accumulation due to the amount of soil involved in deep depth sites.

Concrete encasement

When the surface of the ground and soil do not have deep depths, they can get protection from the outer encasing with the help of concrete. Encasing the surface with concrete is very effective yet very expensive when it comes to sites that have deep soil depths.

STEEL PILINGS

Summary

Steel piles are sheets that are the core requirement whenever building at a construction site. It is important to understand different kinds of piles when you want to incorporate them in your construction. They come in different kinds so it is better to get a judgment from an engineering team about choosing the right one.

These sheets have their own pros and cons.  Its major benefit is that they provide a sturdy foundation on which you can construct. On the other hand, you might face some difficulties when dealing with corrosion impacts. All in all, they are some great ways and options to use these steel pipes in making a powerful structure.
