Pin Piles in Florida

A driving shoe is placed after preparation of the working platform and pre excavation of the footings. The steel pipe piles are about 5 feet long and formed with a shock sleeve. The first pipe is installed into the driving shoe and then one pipe after the other stuck together and driven down until driving criteria is reached.
If there are grouted piles to perform, the first pipe is cut close to the driving shoe so that the mortar is able to full fill the free space between the pipe and the soil performed by a larger diameter of the driving shoe. Diameters from 3” up to 12” are normal depending on the soil conditions
Directly after installing the piles, the pile heads designed as steel load spreading plates are placed on the steel pipe piles.

• Resists compressive, uplift/tension, and lateral loads
• Can be installed in restricted access and low headroom sites with minimal disruption to operations
• May avoid utility re-routing
• Alleviates quality assurance concerns associated with cast-in-place piling in weak soils
• Can be combined with other techniques to meet unique or complex project requirements cost-effectively and efficiently
• No spoil
• Can make the optimum pile length according to load and soil conditions

The load capacity of each pile can be controlled with driving criteria and the optimum pile length achieved. Driving observations support engineering review; capacity verification and load testing follow the specified project criteria. A static load test can give values of the pile load capacity.
