Innovative contactless Anchor Measurement with elastomagnetic Sensors

The Dywidag-Systems International GmbH has played a key role in recent years in the development of an innovative measuring principle for geotechnical ground anchors. The measuring principle is based on the elastomagnetic properties of ferromagnetic materials, so-called Dyna Force. The sensors can be mounted on the steel tendon over the anchor free length and the bond length. The measurement of force occurs in the steel tendon in a contactless manner. This report first looks at the physical background of the measuring principle. Subsequently, practical findings, possible fields of application and knowledge derived from them are presented with reference to examples such as the construction pit at the Opernplatz in Frankfurt and the Grancarevo dam in Bosnia and Herzegovina.

Innovative mechanised Installation of the Geosynthetic Sealing System in the Silberberg Tunnel in Thuringia/Germany

The 7,391 m long Silberberg Tunnel on the new Ebensfeld-Erfurt rail route in Thuringia/Germany was driven by trenchless means and lined using geomembranes. Umbrella seals, single-layer and double-layer all-round seals were applied. This article deals with the mechanised installation of geomembrane lining materials using an innovative laying device.

Innovative Accessories for Tunnel Equipment and Geosynthetic Sealing Systems for trenchless Tunnels

Encouraged by queries from the construction industry, the Meese GmbH has developed innovative accessories for sealing geomembranes in trenchless tunnels. These accessories prevent plastic sealing geomembranes from being penetrated and facilitate the attachment of loads and installation.

Crossrail Major Project in London – Concrete Logistics with innovative Concreting Shuttle

42 km of tunnels are being built for London’s Crossrail project of the century. An innovative concreting shuttle devised by the Karl-H. Mühlhäuser GmbH & Co. KG aids in tackling the sophisticated concrete logistics for the track installation in this major project. Here the focus is on the concreting shuttle and its manner of functioning in continuous operation. Findings obtained during its application are also explained.

Powerful underground Cooling with the “Pressure Exchange System”

The “Pressure Exchange System” (P.E.S.) is a technical component, which is applied in a central location for underground cooling facilities. The system forms the interface between the two circuits of a cooling system – the primary circuit, connecting the surface system components of the cooling facility with the underground P.E.S., and the underground secondary circuit, which links the P.E.S. with the consumers (coolers). The P.E.S. effectively fulfils the transfer of temperature between the circuits, an important function so essential for the efficiency of a cooling system. The manner of functioning and the associated advantages of the system are presented in this report.
