Ankerkraftmessung mit Huggenberger-Kraftmessdosen, Drahtlos-Datenübertragung und Web-Datenmanagement
Ankerkraftmessungen für Baugruben, Stützkonstruktionen, Felswandsicherungen und für andere geotechnische Strukturen sind, innerhalb des Sicherheits- und Nutzungsplans, ein wesentlicher Bestandteil der Risikobeherrschung im Bauwesen.
Huggenberger AG verfügt über Systeme, Know-How und einer Internet-Projektplatform um die Instrumentierung mit Ankerkraftmessdosen, deren automatische Erfassung und Darstellung auf der Projektplatform, dem Huggenberger-Monitor, effizient auszuführen.
Lesotho, Katse Dam
The Katse Dam, constructed during the first phase of the Lesotho Highlands Water Project, is a 185m high double arch concrete dam with a crest length of 710m. The geological formation of the Katse dam area is characterized by the existence of almost entirely basaltic, nearly sub horizontal, lavas flow deposits. The main discontinuities are composed of sub horizontal shear zones and flow contacts, layers of basalt and some sub vertical stress relief joints.
After main construction work was completed, a set of direct and inverted pendulums, partially equipped with manual operated and partially with automatic pendulum measuring devices not originating from Huggenberger AG, has been installed. Early 2018, Huggenberger AG supplied and instaled 10 telelot units of the type VDD3V4 to refurbish the old monitoring system.
Weggis K2B Horlaui
In June 2018 Huggenberger AG was appointed to refurbish an existing system to monitor the Horlaui-rockcliff in Weggis, Switzerland with ne additional sensors, data loggers and data transmission. After installation this rock cliff was stabilized and partially rock formations have been excavated. The monitoring played an important part to analyze stability and for decision making of the construction work to decide what parts can remain and what parts of the cliff have to be demolished or anchored.
Concrete dam Maigrauge, ZSL and ZS-Systems
The small gravity concrete dam, constructed 150 years ago in Fribourg, Switzerland, was increased in height to 21m and has a crest length of 113.5m. The dam, operated by Groupe E (Broc, Schwitzerland) is equipped with different Huggenberger-monitoring systems.
Due to the fact, that the dam has no inspection gallery and the foundation is on weathered Molasse type rock, special systems have been installed and monitor the dams behavoir since many years accurate and reliable.
