Flood Protection in Germany – Sludge Removal from the Saxon Radeburg I Reservoir with a Suction Dredge and Geotextile Tubes

#Murray, Howard #Wortelboer, Rob J. M.

In 2014, the State Dam Administration of Saxony (LTV) in Germany used geotextile dewatering tubes for the first time in the removal of sludge from a flood-retention reservoir. The article explains the dewatering method and its use for the Radeburg reservoir near Dresden.

Geotechnical Investigations of Dams with mobile LIDAR and photogrammetric Systems

#Hofmann, Julian #Löwen, Martin #Herrmann, Richard A.

3D surveys with mobile LIDAR and photogrammetric systems facilitate profile analyses, localisation of weak points and the detection of deformations at dam structures. The article examines innovative measurements and analyses and the utilisation of the results for stability investigations taking the example of the Alfhausen-Rieste flood control reservoir in Lower Saxony.

World Record in Rockfall Protection

#Braun, Paul

In October 2017 the mark of 10,000 kJ of impact energy in rockfall protection has been broken. At the Geobrugg test site a 30-meter-long and 7-meter-high net installed on a rock wall stopped the impact energy of a 25-ton concrete block.

Tunnels sealed with Geomembranes: Securing the Inner Lining Reinforcement in Position through innovative Anchors

#Meissner, Marc #Meese, Ludwig #Meese, Felix

Measures to secure the inner lining reinforcement can be necessary in special cases in trenchless tunnels with geomembranes. This report introduces innovative anchors jointly devised by the Meese GmbH and the Naue Sealing GmbH & Co. KG, which avoid penetrations of the seal and constraints. They have already been used successfully in practice.

Preweakening of Rock – a Renaissance for hard Rock Cutting?

#Philipp, Matthias #Späth, Bastian #Bartnitzki, Thomas

Cutting excavation techniques coupled with methods designed to preweaken hard rock can represent the key for the economic continuous extraction of some of the world’s most valuable raw material resources. At the Rock Cutting Centre at Aachen University (RWTH) hard rock samples were preweakened with high-pressure water jets and subsequently investigated using modern cutting concepts to establish their cutting technological implications.

Bucket Wheel Excavator Barracuda – A revolutionary new Mining Concept

For mining in hard materials with a compressive strength of up to 50 MPa, Thyssenkrupp has developed the Barracuda bucket wheel excavator. With an improved steel structure and innovative bucket wheel the field of application of bucket wheel excavators is widened from digging only to cutting and digging. It thus bears a huge potential for a step change and to reach considerable improvements and cost reductions in mining operations. This article explains the potential.

The Building of two Freeze Shafts commissioned in Belarus

#Otten, Frank

The Deilmann-Haniel GmbH has been commissioned by the Slavkaliy GmbH to sink two freeze shafts each roughly 750 m for the new Nezhinsky facility to the south of Minsk in Belarus. The annual output is planned to be around 1.1 to 1.2 million tonnes of potassium chloride. Both shafts are to be sunk by Shaft Boring Roadheaders (SBRs). German, Belarusian and Russian workers will be employed.

Improvement of Methods of Strength Calculation for Pipeline Flange Joints

#Myagkov, Konstantin A. #Gaffanov, Rustem F. #Zich, Alexej #Serikov, Dimitri Yu. #Shotidi, Konstantin H.

Industries attribute major importance to the durability and reliability of pipelines including the flange joints. Existing methods of flange joint calculations and neglected factors are discussed. Improvements are proposed particularly with regard to the applicability of the finite element method.
