The $11.5 BILLION Mega-Tunnels in Belgium 📍🇧🇪 This might be the coolest infrastructure project we've seen... Crucial for trade and travel, the Ring Road and Antwerp's transport system are set to change drastically with insane engineering and construction! The Oosterweel Link Project 🛣️ 1. The Scheldt Tunnel 🚇 - A 1.8km underwater tunnel created from 8 massive segments, each weighing 60,000 tonnes. Yes, 60,000 tonnes! In Zeebrugee, 100km from Antwerp where there is much more space, these tunnels have been constructed in a 25m deep excavated hole by the sea. Once finished they will be sealed at each end, with the hole flooded so the segments float to the surface. Sometime in 2025, tug boats will slowly transport each segment 180km around the coast, through the Netherlands, and down to Antwerp. Lowered into a trench on the seabed, water between the segments will be pumped out creating a vacuum and watertight seal = tunnel. 2. Oosterweel Junction 🚙 - Traffic will surface briefly, sunken into the landscape to be less of an eye-sore, heading up to the port or down into another set of tunnels.  3. Canal Tunnels 🚢 - An engineering marvel! Stacked two-by-two, these 4 2.5km tunnels travel under the Albert Canal and connect with the existing ring road. Stacking the tunnels prevents excess space from being taken up, allowing for the depth required by ships using the canal to be maintained.  4. Viaduct Demolishment 🌉 - To connect the new tunnels to the existing ring, another set of tunnels under the canal will be built in place of the original viaduct. Obstacles stand in the way however, with the original city walls underground where the tunnels are intended, traffic, and residential areas close by. Planned to host 3 lanes each way with a 6m wide bike track, these tunnels are massive! Construction started in 2018 with anticipated completion in 2030 📆 What're your thoughts on this gigantic project? #oosterweellink #antwerp #brussels #belgium #tunnels #viaduct #canaltunnels #albertcanal #ringroad

#deepexcavation with #reinforcedconcrete diaphragm walls and #reinforcedconcrete waler and strut bracing from #frankfurtammain. In this approach, you cannot preload the bracing as the struts are cast in place.

A major infrastructure project is currently underway that is set to provide the capacity to transport 180,000,000 passengers annually. And, at the very centre of it, are three Terex rough terrain cranes helping aiding a unique method of wall construction.

An original replacement for drawbridges has been found The ideal bridge is one that allows cars to travel at a low altitude above the water and ships to pass freely underneath. The construction of high bridges is very expensive, and movable structures are inconvenient to operate. One Dutch engineering firm has proposed a floating structure that does not involve the bridge itself. Instead, it lowers the water level by 8 meters, clearing the way for sea vessels. The inclined gateway was developed by Dutch engineers from Royal Haskoning DHV, one of the world's largest engineering companies. By tilting, the lock temporarily lowers the water level in one of its channels, allowing a yacht with a high mast to pass under the low bridge. The structure is powered by energy from built-in solar panels. The best way to understand how a tilt gate works is to watch the video below. https://lnkd.in/dYdAdmgE #nikolaysgeneticslessons

Cut & Cover method in construction. The top-down construction method was first used in the 1970s in the construction of metro stations in Paris and Milan and became known as the Cut & Cover method. In this method, the tunnel structure is built first, and then the external environment of the tunnel is filled with embankment materials. #tiefbau
