Screw piles are highly essential to give the needed foundation and stability for earthquakes while constructing any building or structure upon any type of surface. With very little noise and far less vibration, they may easily be installed.
The screw piles are made of hollow sections in circular steel and equipped with one or more helixes. The screw piles are squeezed into the earth rather than expecting a constant pitch. The hubs and shafts are especially suited for terrain conditions.
After reaching the destination depth, the screw pile is secured at the target location and is usually filled with concrete. The exceptional reinforcement connects the framework. Powerful hydraulic engines are utilised to apply huge torques to screw the ventilation pole in the ground. And the engines are fitted to large machinery for handling.
Many construction engineers and contractors are always in a dilemma that why they should opt screw piles? What are the benefits of screw piles? Therefore, in this post, we thus try to reply as easy and straightforwardly as possible to these questions.
Benefit #1:
Crane with a pile hammer or a wide drilled shaft platform, with standard building equipment, such as a paddle or small excavator, is fitted with a hydraulic high time engine. This makes movement rapid and cost-effective and requires just one operator to set up screw piles.
Benefit #2:
You don’t need to wait to set concrete or grout or wait for excess water pressure to dissolve. Most basic kinds of fixing methods feature single screw piles. Thus, this plays an essential function when the structure is short, and the remainder of the project is dependent on the placed foundations and anchors.
Benefit #3:
The screw piles installations cause minimal or no disturbances on the site and generate no soil cuts in general, in comparison with most other types of construction operations requiring the installation of driven piles, shafts or other fixers. The site is therefore kept clean and minimised after installation and project expenditures are reduced.
Benefit #4:
Installation is also crucial in minor vibrations for some of the vibration-sensitive projects in construction. The screw piles have a minor work path or are not disturbed by the surrounding buildings. As no soil is removed, they may also be efficiently utilised in locations where soils can be polluted.
Benefit #5:
Screw piles are manufactured using top-quality recycled steel for fabrication, resulting in the reduction of carbon footprint. In addition, it helps in conserving natural energy and resources like these can be reused with a minute or no changes in the building integrity. Thus, many manufacturers use screw piles to temporarily support the structure.
Benefit #6:
The best feature is easy to access and convenient removal or reuse if the structure changes or is not required anymore.
Design Analysis
There are certain factors based on which you may determine the designs according to your requirement, these are:
- Geotechnical information, including Borelog, Cone Penetration Testing (CPT), etc.
- The location and number of the requirement of screw piles give the detailing required in business planning.
- For carrying different loads, different designs, helix sizes, and shaft types are taken under consideration for designing them.
- The size of the appliances is based on the location they are used; therefore, an engineer needs to determine the size that can be useful at a particular site.
Conclusion
Hope with this article we have been able to help you identify the benefits of the screw piles and helped you clear some of your doubts related to screw piles. You may always contact the manufacturers for more extensive information and varieties of screw piles for any more queries.
