Luxemburg farmers place their faith in the E+S Site Road - Optimum load distribution
Sep 15, 2005
The Beckerich-Huttange-Nordange main collecting system in Luxemburg, which Weiland Bau S.à.r.l. is constructing on behalf of the Syndicat Intercommunal de Dépollution des Eaux Résiduaires de l’Ouest (SIDERO), is about 3,300 m long. In addition to the new collecting system – a corrugated sheath measuring DN/OD 315 to 400 mm – a district heating pipeline and a duct for an optical fibre cable are also being laid in the trench in a single work process. To protect the ground of what is mainly grazing land, the contracted company is using about 500 running metres of Site Road from Emunds+Staudinger. This satisfies the client’s brief as well as the needs of the affected farmers, for it eliminates extensive soil extraction and removal, as required for the construction of a conventional site road of crushed rock. The temporary Site Road is quickly and easily laid. Owing to their optimum load distribution, the 2.4 m long and 3.8 m wide elements protect the ground effectively from destruction and compaction by construction vehicles.
Since the 2.5 m wide and up to 3.5 m deep trench passes almost exclusively through valuable pasture, the concerns of the affected farmers were initially considerable. It was essential that the construction vehicles should do as little damage as possible to the topsoil. It was also important not to destroy the drainage system in the clayey soils typical of the region that tend to become waterlogged. For this reason, the client opted for a temporary site road – a procedure that, in the opinion of everyone concerned, has paid off. The production and removal of a conventional site road of crushed rock is generally extremely laborious. "The tasks involve bulldozing or excavating the topsoil and storing it temporarily, laying a geotextile and a course of crushed rock with subsequent compaction, excavating and removing the crushed rock, and replacing the topsoil," explains Project Manager Edgar Krings, Weiland Bau S.à.r.l. With the new E+S Site Road, all these tasks are omitted. No special vehicles are needed for moving materials to and from the site. The individual Site Road elements can be laid directly, without any large-scale preliminary earth moving. At the same time, they also withstand extreme loading. Owing to their good load distribution – point loads are spread over an area of about 9 m2 – the Site Road elements provide the necessary stability even on soft ground.
What’s more, thanks to simple design and special connectors, assembly is relatively quick. "The Site Road is composed of rugged angle elements laid lengthwise and special transverse profiles," explains Frank Abeling, Site Road Product Manager, Emunds+Staudinger GmbH, describing the elements that have already been successfully used in building construction and civil engineering assignments at home and abroad. "Assembly of the 2.4 m long and 3.8 m wide elements on site couldn't be simpler," Abeling continues. An excavator lifts the elements one after another from a reversing truck, and then they are joined together with a kind of chain joint. For the project in Luxemburg, however, it was possible to omit this step, as the panels pressed themselves immovably into the clayey ground.
