Hydraulic pile driving vs conventional pile driving

Times are changing and so is technology. More and more people start working with a hydraulic impact hammer. This could be of many reasons, such as: noise level, environmental issue, efficiency and so on.

Hydraulic impact hammers and especially the ones of PVE can easily be controlled in drop height and therefore the contractor is able to control the energy and blow rate. Starting up the conventional diesel hammer is depending on the soil conditions. The fact that a diesel hammer only has two positions to start from: full fuel and half makes it a hammer which is difficult to start/control which can lead to unsafe situations.

PVE 7NL hydraulic impact hammerPrinciple of pile foundations

A pile foundation is necessary when the loads of a building will be higher than the upper soil layer can take. Piles are installed primarily to avoid settlements which could result in big damages and dangerous situations. In a limited number of projects piles are installed as ‘tension’ piles these are installed to prevent the object from lifting out of the ground. A well-known example are piles installed under the high tension electricity piles. Due to high forces created by wind the piles need to be ’anchored’ in the ground.

PVE hydraulic hammers are used for the installation of: 
- Wooden (Timber) piles
- Steel H-beams
- Steel casings (tubular piles)
- Steel sheet piles
- Precast concrete piles
- Driven cast in place (DCIP) piles
