The concept of composite lock gates with Infracore® Inside is an excellent example of Dutch innovation, and enthusiastically received by the market. In 2012 the first InfraCore lock gates were realized: for the new canal from Erica to Ter Apel (ETA), FiberCore Europe has fabricated four lock gates in fiber reinforced polymers (FRP). Clients were the Dutch provinces of Drenthe and Groningen.
The gates measures are 5,0m tall by 3,6m wide, and were built using InfraCore® Inside technology. They have been engineered such that their volumetric mass matches that of water, exerting very small loads on the hinges and operating mechanism as a result. The detailing and the gates themselves therefore feature a very long life span and are insensitive to corrosion or rot, as is the case with conventional gates. Also, the gates are virtually maintenance-free.
The lower cost, low maintenance and sustainability of the concept have ensured that, in addition to the first ETA project, several other projects already started. Among this new projects are world’s biggest lock gates to be realised in Fiber Reinforced Polymers (FRP). These lock gates will be located in Tilburg, the Netherlands.
The gates will be 13 meters tall by 6 meters wide, and built using FiberCore Europe’s InfraCore-technology. These lock gates follow the trend for low-maintenance infrastructural works that has been set by the numerous FRP bridges already built with the same technology. The gates will be installed in the Wilhelminakanaal and are part of a major project to widen the canal to allow bigger ships to use it. This includes widening the locks to 10,5 meters.
