Installation of sheet pile dimensions

Prior to installation, piles should be carefully inspected for straightness, cracks and the integrity of the interlocking components.

Driving must be carefully monitored and should stop immediately if the pile ceases to penetrate the soil, before moving on to the next pile along. In some cases, several adjacent piles will be unable to penetrate to the design depth. At this point, effort should be made to remove the obstacle, either by partial excavation or using a water jet. There is an acceptable number of "under-driven" sheet pile dimensions, but this will vary according to the specific design requirements.

Sheet pile dimensions have a tendency to deviate from a vertical plane during driving and instead lean sideways. This is due to encountering obstacles within the soil which act as deflection. Guide controls should be used to counter this.

One technique is to drive piles in panels. This involves pitching and driving two piles to part or full-penetration at either end of a panel of piles. The panel is therefore supported by the ‘bookended’ piles during driving to their final position. The pair left on the end then forms the support of the next panel along.

Another technique is to use trestles and walings to support and position sheet pile dimensions during driving.

Vibratory hammers are often used to install sheet pile dimensions, although if soils are too hard or dense, an impact hammer can be used. At certain sites where vibrations are a concern, the sheets can be hydraulically pushed into the ground.
