Stainless splicing for Montreal’s new Champlain Bridge

Stainless rebar couplers to splice rebar horizontally on the structure.

Reinforcement for bridgeDie neue Champlain Bridge ist eine 3 km lange Brücke über den Sankt-Lorenz-Strom am südöstlichen Eingang von Montreal in der Provinz Quebec (Kanada).

The Champlain Bridge is one of the busiest bridges in Canada and plays an important economical role for its city as it is part of the main itinerary to the United States, accessible 60-km South.

For this project, Dextra is supplying its Rolltec mechanisches Spleißen von Bewehrungsstäben system, in both Carbon Steel and Stainless Steel versions. Rolltec is a certified system by the Department of Transportation of the State of Quebec.

Teams are back to run Peak24!

Dextra teams at the race starting point!

Way to go Dextra team!This year again, Dextra lined up 2 teams of 12 runners at Peak24 race in Hong Kong! The teams were featuring a mix of Dextra Guangzhou and Dextra Hong Kong staff, pushing together their limits for the good cause and in an incredible atmosphere!

Peak 24 Race is a charity race aiming to raise awareness about slavery and human trafficking problem in the world, and especially in Asia. Funds raised by Peak24 will be donated to the 24 Hour Race, a Hong Kong-founded & international youth charity which inspires students in five countries to join the movement to eradicate modern slavery. The profits raised from us will directly benefit the expansion of the 24 Hour Race movement.

Bar systems for liquid gas tanks

In the United Arab Emirates, Dextra recently delivered a new Oil and Gas project. Dextra tension rods have been used for the support of structure supporting very large liquid gas tanks.

For this application, Dextra engineered, manufactured and delivered bar assemblies based on Carbon Steel bars Gr.355 of diameter Ø120mm. Each Spannstange system is composed of two segments spliced at the lower half of the assembly. The system is mounted onto gusset plates thanks to their fork ends, which can be connected to the structure in just a few minutes by simply sliding in a pin in the middle of the fork.

For length adjustment and tightening, turnbuckes, positionned at the lower half of each tendon, are simply rotated to bring bar segments closer to each other and tension the overall system.

Deliveries for Riyadh Metro stations

riyadh metro

Riyadh Metro ist ein riesiges städtisches Verkehrssystemprojekt, das in Riad, Saudi-Arabien, im Bau ist. Das Projekt wird 85 Bahnhöfe umfassen, die entlang von 6 Transitlinien mit einer Gesamtschienenlänge von 176 km gebaut werden. Es wird erwartet, dass das System bei seiner Eröffnung im Jahr 2018 täglich mindestens 1 Million Passagiere bedienen wird.

For this large infrastructure project, Dextra Middle East has been involved on various stations and packages.

Ausgrabungsarbeiten

Before proceeding with general construction works, during early excavation phase, it is required to anchor retaining walls back into the stable ground in order to prevent any wall displacement. This will allow to keep excavating in a safe environment.

For that purpose, Dextra supplied steel ground anchors installed through retaining wall. Each system is based on a high-tensile fully threaded bar, coming with nut and plate, and grouted to provide bonding with the soil.

Floß- und Vertikalverbindungen

Bartec-Bewehrungskupplungen were supplied for the works in the stations. Couplers were used for slabs, column and wall connections. A typicall application on this project is to cast rebar couplers in the concrete with reinforcement, and then proceed with second phase bar connection at a later stage.

Unitec bolted couplers can have also been use on various parts of the project. Typically Unitec is used when overlap is planned but lapping length appear to be too short to perform a safe splice. In that case Unitec provides a convenient and full performance connection.

Die Installation der BITEC-Spannstangen ist jetzt abgeschlossen!

Dextra belieferte den Auftragnehmer Italian-Thai mit Spannstangen zur Unterstützung der Dachkonstruktion der Erweiterung von BITEC, einem führenden Ausstellungs- und Kongresszentrum im Zentrum von Bangkok. Die Installation wurde 2016 erfolgreich abgeschlossen!

Insgesamt lieferte Dextra 298 Baugruppen in verschiedenen Durchmessern, die jeweils aus mehreren Stäben bestanden, die mit Kupplungen und Spannschlössern verbunden und mit Gabelenden an der Struktur verankert waren, wobei die Gesamtlänge der Baugruppen in einigen Fällen mehr als 50 Meter betrug (durchschnittlich 33 Meter).

Für solch große Strukturen Spannstangen bieten im Vergleich zu anderen „Spann“-Lösungen eine Reihe von Vorteilen: geringere Dehnung unter Last, geringere erforderliche Vorspannkräfte, bessere Korrosionsbeständigkeit, geringere Langzeitentspannung und geringere Wartungs- und Überwachungskosten.

 

Start the year on strong bases

2017 is upon us and all the Dextra team wishes you a wonderful and prosperous year ahead, and a lot of succesful projects too!

What better way to start the year than making sure those projects will be will built on the strongest bases possible? For that we got you covered!

Dextra recently updated its Ground Engineering range documentation, featuring all our ground anchor solutions. Our unique range covers both steel and FRP (Fiber Reinforced Polymer) solutions. This unique mix will cover all your possible anchoring challenges, in all soil conditions, from permanent to temporary applications.

Dextra couplers on recent metro projects in France

In Paris, the expansion of Line 14 is part of the Grand Paris Express urban transportation plan. The fast subway line’s expansion will soon cut through Paris to go all the way North to Saint Ouen. Dextra supplied more than 70,000 Fortec couplers used in the stations of Orsay and Pont Cardinet. 

In Rennes, Western France, Dextra is successfully delivering Fortec and Rolltec rebar couplers in all four packages constituting makingthe 15 stations and 12.6 kilometers (part elevated, part underground) of the new Line B of the Rennes subway network. Couplers are used in various locations such as retrieval shaft, stations and trenches between stations.
