Standards and regulations
HPD piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12699, and the recommendations of the “Piles” working group (EA-Pfähle). The cast-iron pipes are 118mm and 170mm in diameter. For further details, please refer to our certification Z-34.25-203 HLV-Pfahl System Stump, which you can download from our website. Loads and pipe diameters should be adapted to prevailing soil conditions. We will be happy to advise you on this.
The first pipe section is fitted with a drive shoe or pile shoe, placed in a pre-drilled cavity, and driven into place. The next pipe section is then picked up and inserted into the conical socket of the pipe that was previously rammed in. The driving process creates a rigid, friction-locked connection. The pile is driven to the final depth, which is determined on the basis of the penetration resistance. The excess is trimmed down to the required height. The remaining piece is fitted with a new drive shoe and immediately used as the starting pipe for the next pile. This means that pile production is waste-free. The pile head is designed with a pressure distribution plate and/or tensile reinforcement, depending on the load transfer requirements.
