Bored piles are a commonly used foundation technique in civil engineering because they offer a number of advantages and disadvantages that must be considered when deciding which type of foundation is best for a project. In this blog post, we discuss the advantages and disadvantages of bored pile construction, with a special emphasis on providing civil engineers with an in-depth understanding of the implications. We also cover factors to consider when using bored piles and possible solutions to the challenges they can present.
What are leaky batteries?
Bored piles are concrete piles that are driven into the ground and then bored to a selected diameter. They are generally used as structural foundations for buildings, bridges, piers and docks. The main advantage of bored piles is the ability to transfer loads from one end of the pile to the other. This load capacity is called “maximum load capacity”. Bored piles can be made of steel, wood or concrete. The steel version is typically used in more demanding applications where a higher maximum load capacity is required. Concrete bored piles are also commonly used due to their high strength and moderate cost.
The bored pile was invented in 1877 by the French engineer Eugène Freyssinet. In France, Freyssinet's company became a leader in the drilling industry in Europe, but he did not patent his invention. This allowed other companies from different countries to use this technology, just as he allowed them to freely use his invention under license. Furthermore, many engineers and scientists began studying this structure as they realized its advantages and potential uses in their fields.
Advantages of bored piles
- The use of bored piles can reduce the number of excavation and restoration steps. They also require less space in a trench than other methods, significantly reducing the amount of excavation required in construction projects.
- Bored piles are quick and easy to install and have minimal impact on traffic or neighboring buildings. The drilled pile installation procedure is based on machines already widely used on construction sites. Installation only requires a suitable base for the pile, which can be quickly excavated with an excavator or backhoe.
- Bored piles also have excellent corrosion and wind resistance and are capable of withstanding active tectonic regions. This makes them ideal for use in many locations around the world.
- The advantage of this method is that it can be used almost anywhere because it does not require a solid concrete foundation. The main disadvantage of bored pile foundations is their cost compared to other methods. Skilled workers are required for proper installation, which increases the overall price of the structure.
- They can be installed in almost all weather conditions.
- They impact the surrounding soil and buildings less than other foundation methods.
- They offer good load capacity and can be used to support large structures.
- They help ensure the necessary stability of a structure and also provide support against lateral pressure forces.
- Bored piles help stabilize the foundations of buildings and other structures by providing lateral resistance to earth or water pressure.
- Compared to solid steel piles, bored piles are more economical and offer more flexibility in design options.
Disadvantages of bored piles
- A major disadvantage of using Leaky Stacks is that it requires more time than other systems. This is particularly true for smaller projects, where just one foundation system like this can be used successfully, rather than combining two different systems, as in larger projects, where both pile foundations and strip foundations can be used in different ways. effectively in different parts of the building structure. the same time.
- Bored piles are more susceptible to corrosion if their diameter is small.
- Noise pollution from machines during installation.
- Vibration of the ground beneath the area being drilled. If drilling is done improperly, it can cause more harm than good, such as: B. Causing landslides, increased settlement, or even rockfalls, which can cause fissures in surrounding structures such as roads or buildings, if not are properly repaired. As long as proper procedures are followed when installing bored piles, there should be no settlement issues once construction is complete, making it an attractive option for builders who need to push soft soil during construction.
- More expensive than other foundation methods
- Requires qualified equipment and operators.
- If installed incorrectly, it can cause disturbances to the surrounding land and buildings.
Now we hope you have clarified the advantages and disadvantages of bored piles.
