Huge step forward in the development of dike-reinforcement technology
Test results with innovative JLD dike stabiliser extremely positive
8 July 2015
EDAM – This morning at 7:14, the test dike on JDL Contracting’s test field in Purmerend was breached in accordance with the calculations. This was the culmination of nearly a year of preparation and field research. The first findings make it very likely that the JLD dike stabiliser can grow into an accepted dike-reinforcement system in the coming year. A huge step forward in dike-reinforcement in the Netherlands and beyond.
Experiment with and without the dike stabiliser
Wednesday evening, 24 June, was the first phase of the container tests on the “green” dike. This dike was built without the JLD dike stabiliser; its purpose was to serve as a check for the calculation model developed for the JLD dike stabiliser. The dike failed as the calculation had predicted.
The second test – with the “blue” dike (reinforced with the JLD dike stabiliser) – started last Monday, 6 July. This dike was loaded with approximately 1 million kg of steel and containers in order to simulate a breach, as planned. The first findings make it very likely that the JLD dike stabiliser can grow into an accepted dike-reinforcement system in the coming year.
The tests yielded unique images. Have a look at these images on www.jlddykestabilization.com.
POV Macro-stability Project
Together with its partners Antea Group, Wiertsema & Partners and Deltares, JLD is developing the de JLD dike stabiliser. This development is an innovative dike-improvement technique whose purpose is to increase the inward stability (macro-stability) of dikes. This technique is executed and financed by Waterschap Rivierenland within the macro-stability POV, a project in the Dutch Flood Protection Programme (Dutch: Nederlandse Hoog Water Beschermingsprogramma – HWBP).
What does this mean?
The completion of this phase of the testing signifies the culmination of nearly a year of field research. The data already gleaned from these tests will be analysed in the coming weeks and used in a report. This report will be submitted to the Expertise Netwerk Waterveiligheid (ENW – www.ENWinfo.nl) at the end of the summer for evaluation. JLD Contracting aims to make the JLD dike stabiliser an accepted dike-reinforcement system this year.
