![]() To ensure this, we first built the new lock, and we only demolished the old one after that, also making sure the Limburg hinterland would remain optimally protected during the works. Except for two weekends, freight traffic remained uninterrupted throughout the entire period. Gate 5 is just south of Nueva Street on the. It was also crucial to minimize disruption to ship traffic on the busy Meuse during the works. Gates 3 and 4 had previously worked in concert to isolate the River Loop from the main channels flood water. Nevertheless, this project also has its own challenges, including the very limited room for manoeuvring when carrying out major lifting operations due to the presence of the existing floodgate. This is the third time BESIX builds such a flood barrier. We implemented a smart solution to avoid leaks: by anchoring the dam walls on each of the four sides of the new flood gate in the limestone rock bed, we created a watertight container. All overflow sills, inlets and outlet sewers in combined and stormwater networks can be secured with Hydro-Latch flood gates to prevent flooding of the. Together with Agidens we designed a simple yet powerful hydraulic lifting mechanism to move the lock gate. Rijkswaterstaat gave us the opportunity to explore innovative solutions. Lightweight aluminum flood gates are available in widths up to 15ft and flood defense heights up to 6ft, and our steel flood gates are designed to any size. Design and construction of the new flood barrier The flood gates can be designed to operate on a dead level threshold allowing unrestricted vehicle, pedestrian and disabled access.He said the city’s Emergency Response Team only closed two flood gates at a time to lessen the inconvenience to residents. And this was good news as it allowed us to work more efficiently and learn from one another. Delaney said the flood gates were closed and evaluated during the exercise. This in itself was already a first: never before had one party been entrusted with the construction and maintenance of a whole flood barrier for such a long time. The operation profile of floodgates differs substantially from that of lock and weir gates. Together with Agidens Infra Automation (now BESIX Unitec), which took care of the mechanical dimension of the project, and Rebel Group, providing financial advice, we were responsible for the design, construction, financing and maintenance of the flood barrier. ![]() Our experience in lock construction enabled us to submit a detailed quality plan, explaining the safety aspects and disruptions during and after the project. Rijkswaterstaat – the executive agency of the Dutch Ministry of Infrastructure and Environment – entrusted BESIX with the construction of the Limmel flood barrier. Quick Dam Flood Gates block doorways from oncoming flood water. ![]()
