Prefab concrete piles

Prefab concrete piles can be driven with IHC Hydrohammer SC-series. The following IHC Hydrohammer SC-types are available for rent and for sale: SC-50, SC-75, SC-110, SC-150, SC-200 and SC-250. This type of IHC Hydrohammer is specially designed to drive concrete piles but is besides that also suitable to drive steel piles at maximum energy.

The standard concrete cap configuration to drive concrete piles is shown in the picture below. The Rampoint of the ram weight hits on a Synthetic Hammer Cushion. The Synthetic Hammer Cushion transfers the energy into the Helmet and through the wooden Pile Cushion into the Pile without damaging the concrete.

Piles which have various shapes and sizes can be driven with an IHC Hydrohammer SC-type. A few examples of different concrete piles are shown below.

The SC-type Hydrohammers can be supplied with an energy rating of 30 up to 250 kJ. Similar as the S-type Hydrohammer which is designed for steel piles the SC-type is capable to drive piles below the waterline. When driving piles below the waterline an air hose is connected to the sleeve through which compressed air is supplied into the hammer to keep water from flowing into the Hydrohammer.

The Prefab concrete piles can be driven with a Hydrohammer in two ways, free riding and leader guided. When driving piles free riding a longer sleeve is required then while leader guided. The reason for the extended sleeve is the fact that the total weight and moment induced by the hammer needs to be transferred through the sleeve into the pile.

An extra option with leader guided pile driving is the use of a Noise Reduction Package. This standard package is available for the SC-50, SC-75 and SC-110. With this package it becomes possible to drive piles in environmentally sensitive areas. For example in urban areas where people live and work acceptable noise level are achieved by using a Noise Reduction Package.
