Driven Precast Concrete Piles
Precast concrete piles are structural elements used in construction projects to support hefty loads and offer ample foundation stability. They are prefabricated and pre-stressed concrete columns, built off-site in controlled environments like factories, and then moved to the construction site for installation.
Driven precast concrete piles are made in circular, square, rectangular, or octagonal shapes and come in one of the major types of precast concrete piles that suit different soil conditions and project requirements. Usually, the diameter of these piles varies between 35 cm and 65 cm, while their lengths range from 1.1 meters to 30 meters. The piles are impact-driven into the soil using an adjustable hydraulic or diesel hammer.
Driven Precast Concrete Piles: Fields of Application
Driven precast concrete piling is used:
- In areas with smooth geotechnical conditions with low to medium weight carrying capacity.
- Across diverse sectors, from residential and commercial to industrial and even artistic installations.
- For supporting ground beams, pile caps, building slabs, or in combination with raft foundations or weight transmission platforms.
- For providing support to large infrastructures, including bridges, railways, embankment support, power transmission towers, etc.
- In areas with poor soils covering better ground conditions or overall aggressive soil conditions.
- In areas with densely thick layers of soft soil and/or high-water table that would cause difficulties for conventionally drilled piles.
- In addition:
- Small pile sizes are used for underpinning in houses and light structures and areas with limited headroom, or, that are hard to access.
- Medium pile sizes are commonly used to provide foundations for new buildings, infrastructure, floor slabs, load transfer platforms, and lateral support for earth retention along with king post walls.
- Large pile sizes are used for pylons, wind turbines, marine construction, river bridge foundations, and bridge supports and piers.
- Here is the step-by-step process of installing driven precast concrete piles:
- The pile drive transports to the site and initiates the pile setup process that includes acquiring permit signature, performing site and platform evaluation, and then setting up the pile driving platform.
- The rig is used as a crane to unload the piles and lay them on the ground beside pile pin locations.
- The hammer line is used to lift the piles and place them over the pile positions.
- The pile driver is utilised to hammer the piles into the ground.
- The pile positions are checked while being driven.
- The piles are tested post-installation.
Benefits of Driven Precast Piles
Let’s find out the major perks of driven precast concrete piles:
- Driven precast piles are constructed in a controlled environment, ensuring consistent quality.
- They are the most preferred for over-water projects such as piles in jetties or dock structures.
- They can often be quickly installed compared to other pile types and enable speedier instigation of follow-on works.
- Driven piles do not bulge in soft ground conditions.
- They usually don’t become vulnerable to damage from the installation of successive piles.
- They come in a diverse array of lengths and sizes to befit the project requirements.
- Driven piles don’t produce junk during installation.
- They can be evaluated before and during installation.
- They retain their shape during installation.
