Innovative foundation solutions and more

With Bauma coming up (April 8-14 in Munich), Douwe Feenstra, marketing manager at Dieseko Group, is happy to tell a little more about the latest innovative developments in the field of vibration-free and low-noise foundations. The Dieseko Group is a worldwide leading developer, manufacturer and service provider in the field of foundation machines in which vibration techniques are a distinctive specialty.

"The product range includes vibratory blocks, aggregates, pile-driving and drilling rigs, pile hammers and vibroflots," Feenstra says. "We are constantly developing machines and accessories to enable the most efficient, vibration-free and/or low-noise piling possible. The demand for these has increased significantly in recent years. We are responding to new needs and stricter requirements for contemporary problems in the field of foundations, including inner-city."

A real gamechanger
As an example, Feenstra cites the Resonator. "A true gamechanger. This technology is going to change a lot: so much faster and without vibrations. Every engineer, contractor, architect or consulting firm knows that you get points in a tender if your footprint is smaller, or if you make preparations and take measures regarding vibrations and noise. If situations arise where a contractor does not have the right equipment to meet these requirements, we can help! Not just by supplying a product but by really entering into an innovative partnership and thus working together to find the best solutions for foundation challenges."

Vibration-free foundations
In 2016, the first Resonator was widely shown to the world: the PVE RD260. With resonator technology (60-160Hz), a sheet pile, tubular pile or anchor pile is placed in the ground in a very environmentally friendly way and completely vibration-free. "We - and our customers -  believe very much in this technology. Over the past three years, together with some of our key customers, we have conducted endless tests, improved the principle and made everything even more reliable. Now it is time to introduce a larger variant: the RD430, which allows you to install larger pipes and sheet piles in urban areas. Even next to a hospital, a railroad or a chemical plant. Our specially trained operators accompany this rental product on a job, so that we can keep it under our own supervision and guarantee quality. Furthermore, we have built the world's largest variable moment vibratory block: the PVE90VM, with which large pipes (between 104 and 266 cm) can be set in urban areas and other vibration-sensitive places. For this, we have now built the most advanced variant of our vibration technology (vibration-free starting and stopping) into the world's largest machine of its kind."

Noise reduction is critical
Reducing noise pollution is becoming increasingly important. There are also more and more regulations for this. "In this we are providing research and thinking. For example, we look at power packs on construction projects. To reduce noise, we have developed a damping package with which we can save between -6 and -10 dB of noise. For vibrating profiles, we have developed a modular noise apron up to a height of up to 20 meters. This is attached to the vibrating block and closed all around, but one side can be taken out -for example, for placing sheet piling. In terms of attenuation, we achieved -7.5 dB at 2 meters distance in a test. A nice solution that we offer to the market and that we can also customize together with the customer." All products that fit within the scope of Dieseko Group. "We bring supply and demand together," concludes Feenstra.
