Tanger Med 2 is the expansion of Tanger Med, a multipurpose deep-water seaport located a few kilometers east of Tangier, Morocco, facing Gibraltar.

The port expansion aims to increase the yearly capacity of the largest port in Africa by 5.2 million containers.

For this large infrastructure project, Dextra supported contractor Bouygues with a rebar splicing solution for the reinforcement of the caissons.

Dextra supplied its रोलटेक solution, which is AFCAB-certified, a requirement for this project. Two Rolltec machines were installed to support the threading activities, completing 360,000 threads in total (180,000 Rolltec couplers).

The couplers were used in the reinforcement of the caissons, which were as tall as 20 to 24 meters. The couplers provided:

  • Temporary openings to solve congestion issues in the reinforcement within the caisson, creating safe passages for men and equipment during the installation phase.
  • Horizontal wall-to-slab connections (from the inside of the caisson perimeter to the slab). For this application, couplers were left pending, allowing the slip form to go up.

पोर्ट ऑटोनोम डी पॉइंट-नोइरे

पोर्ट ऑटोनोम डे पॉइंट-नोइरे (पीएपीएन) अटलांटिक महासागर पर स्थित एक प्रमुख बंदरगाह है, जो कांगो गणराज्य का हिस्सा है। यह राजधानी ब्राज़ाविल से 500 किलोमीटर रेल लिंक द्वारा जुड़ा हुआ है और क्षेत्रीय विकास में महत्वपूर्ण भूमिका निभाता है, जिससे कांगो लोकतांत्रिक गणराज्य, अंगोला और गैबॉन जैसे पड़ोसी देशों के साथ व्यापार को सुविधाजनक बनाया जा सके। सालाना 600,000 से अधिक कंटेनर गुजरने के साथ, बंदरगाह का यातायात लगातार बढ़ रहा है।

पीएपीएन की महत्वाकांक्षी विकास योजनाओं का समर्थन करने के लिए, डेक्सट्रा ने पोइंटे-नॉइरे के कई 16 मीटर गहरे घाटों के लिए इस्पात संरचनाओं की इंजीनियरिंग और आपूर्ति के लिए ठेकेदार एसएआईपीईएम के साथ सहयोग किया।

2011 और 2012 के बीच, डेक्सट्रा ने लगभग 1,000 टन की आपूर्ति की समुद्री टाई बार्स ग्रेड 700 में, जो हमारी श्रेणी में सबसे अधिक है। ये उच्च ग्रेड बेहतर प्रदर्शन-से-स्टील अनुपात प्रदान करते हैं, जिससे छोटे व्यास वाले बार की अनुमति मिलती है, जिसके परिणामस्वरूप रसद और स्थापना में बचत होती है।

डेक्सट्रा ने कॉम्बी वॉल्स पर स्थापित वेलिंग बीम भी प्रदान किए। ये बीम स्टील की दीवारों और बड़े व्यास वाली टाई रॉड्स के बीच एक इंटरफेस के रूप में कार्य करते हैं। चूंकि वेलिंग बीम्स रॉड्स को सहारा देते हैं, इसलिए उनका आकार, अंतर और स्थापना टाई रॉड कॉन्फ़िगरेशन के अनुरूप होनी चाहिए। अनुकूलता सुनिश्चित करने और स्थापना प्रक्रिया को सुव्यवस्थित करने के लिए, डेक्सट्रा हमेशा टाई रॉड असेंबली के साथ वेलिंग बीम्स को डिज़ाइन करने और वितरित करने की सलाह देता है।

2015 से 2016 तक, डेक्सट्रा ने क्वे डी के निर्माण के लिए परियोजना के दूसरे चरण में भाग लिया।

The MultiRio Container Terminal, located in the Rio de Janeiro Port, specializes in the import/export of finished goods. To increase its shipping capacity by at least 50%, MultiRio launched an expansion project in 2012 to add extra quay length and accommodate more containers.

To support this pier expansion, Dextra partnered with contractor Andrade Gutierrez for the engineering and supply of Marine Tie Bars.

In 2014, Dextra supplied 100 tons of steel rods in medium diameters M56 and M59. The rods were anchored to the wall using swivel plates and nuts, allowing for 5° multidirectional adjustment.

These plates were positioned onto the waler beams, which were also supplied by Dextra. Waler beams are installed onto the sheet piles, and their design is directly influenced by the chosen Marine Tie Bars solution. For example, the spacing of the beams is impacted by the diameter of the bars and the angle of the rods.

Between the wall, Hinge couplers were installed in line to allow for additional vertical tolerance. This was necessary to counteract ground settlement, which can occur over time due to the heavy cranes operating and the piles of stored containers. The Hinge couplers provided the flexibility needed to accommodate any vertical movement and ensure the stability of the structure.

The Port of Sète, located on the Mediterranean Sea, is the largest fishing port in southern France and also serves numerous ferry routes to North Africa, including Tangiers. As part of its efforts to increase container capacity, the port is adding a new quay (Quay H), 15 meters deep, to improve both handling and storage of containers.

To support contractor Soletanche-Bachy in the construction of this new quay, Dextra engineered and supplied 74 large समुद्री टाई बार assemblies, the largest in our range at M160. These large-diameter assemblies reduce the number of sets required by increasing spacing between each rod.

The tie rods were anchored into the D-Wall using ball cages, which allow a 10° rotational angle in all directions. After excavation, the ball cages were opened to enable reconnection of the threaded ends of the rods.

The New Bay Bridge was a large civil engineering project undertaken between 2002 and 2013. The aim of the project was to replace two segments of the Bay Bridge that were vulnerable to earthquakes with a new structure designed to withstand seismic forces.

For this project, Dextra was involved in two segments of the renovation: the approach to the Bay Bridge on the San Francisco side and the eastern segment from Yerba Buena Island to Oakland.

Dextra supplied its बार्टेक® Headed Bar systems for this project. Headed Bars feature an anchor disc mounted on the end of a rebar previously prepared for the Bartec® system.

का उपयोग हेडेड बार्स provides a smart and compact alternative to long rebar hooks in areas where reinforcement is particularly congested. Unlike hook bars, Headed Bars are easy to install, as end anchors can simply be screwed onto the reinforcement at a later stage, after the reinforcement is in place.

For the approach to the Bay Bridge in San Francisco and the eastern segment of Yerba Buena Island, Bartec® Headed Bars were used for shear reinforcement in the column foundations as well as in the bridge hinges.

The Bartec® Headed Bars solution is approved by Caltrans (the California Department of Transportation) for all imperial bar sizes #3 to #18 and is also certified by the ICC-ES.

The Nhat Tan Bridge is an impressive cable-stayed bridge spanning the Red River, located north of Hanoi. The total length of the project is 8.9 km, including the 3.75 km main bridge.

The bridge serves as a new gateway to Hanoi, significantly reducing travel time to Noi Bai International Airport, the second busiest airport in Vietnam by passenger volume.

The bridge was inaugurated by the Ministry of Transport of Vietnam and opened to the public on January 4, 2015. It has since been renamed the “Vietnam – Japan Friendship Bridge.”

Dextra has been involved in the Nhat Tan Bridge since the early stages of the project, supplying the widely used बार्टेक® rebar couplers, the leading rebar splicing solution in Vietnam. Bartec® connections were used in various parts of the project, including approaches, foundation piles, pile caps, and bridge segments.

Bartec® couplers offer a versatile rebar splicing solution, as the same standard coupler can be used for both standard connections (where the rebar rotates into the coupler) and position connections (where only the coupler rotates, useful when rebar rotation is not possible). Dextra supplied more than 130,000 connections in total for this project, enabling the lifting of heavy elements.

For the temporary operations of lifting and securing the precast girder segments, Dextra also supplied 36 tons of high-tensile PT bars.
