Waterproof seismic protection for the Cayirhan Bridge

MAURER protects huge sliding isolation pendulums in Turkey against inundation by means of a rubber ring.

Munich, Cayirhan. The Cayirhan Bridge crosses the Sariyar reservoir west of Ankara. Its pillars are periodically subjected to inundation. For the new bridge construction, large sliding isolation pendulums (SIP®) were designed, which have to fulfill three core tasks: ensuring full functionality at any time by preventing intrusion of dirt particles, accommodation of high loads exceeding 10,000t as well as enabling service and seismic movements with a corresponding reduction of horizontal forces. As a specialist for seismic devices and bearings, MAURER has been chosen to deliver these SIP® bearings as well as all other bearings for the bridge.
