INJEKTION WITH RAM INJEKTION LANCE
BUILDING REPORT FOR SCHWARZE PUMPE INDUSTRIAL AREA
In this process special steel pipes with lateral outlets and tip are rammed into the soil. Suitable extensions are available with and without outlet openings. Especially suitable for low depths in well penetrated soil. The maximum embedment depth is dependent on the ground conditions. In practice, it is possible to embed at depths of up to 15 meters. The injection material may penetrate the soil through the openings. When injecting under base plates these have to be pre-drilled accordingly. For sealing the packers are used with a coupling sleeve.
Drinking water reservoir 1 and 2 on the area of the "Schwarze Pumpe industrial area" have a storage space of 2800 cubic metres each. They were built in the period from 1989 to 1991 as standardized projects (series "PROWA"). read more
GAS PIPELINE CONTRUCTION IN THE NATURE RESERVE WISMAR
BUILDING REPORT FOR WISMAR GAS PIPELINE
The Baltic Sea Pipeline Link (OPAL) transports natural gas from Lubmin (Mecklenburg-Vorpommern) to Olbernhau in Saxony and is part of the connection to the Czech Republic. The pipeline was welded together from 26,000 single pipes (22.3 mm wall thickness and 1.4 m diameter), each 18 m long and with a weight of 15 t. They were installed in a trench with 1 m soil covering. The annual capacity of the pipeline is 35 billion cubic meters. The pipeline has a length of approx. 470 km, of which 270 km runs through Brandenburg and 100 kilometres through both Mecklenburg-Western Pomerania and Saxony. Special technical requirements had to be observed in the areas where the rivers Peene, Spree and Elbe are crossed. The pipeline was completed in 2011.read more
