The construction of Binh Khanh Bridge is a part of Vietnam’s Ben Luc – Long Thanh Expressway project, which will run through Ho Chi Minh City and southern Long An province and involves the construction of 58-kilometer long roads.
Being started in 2016 and scheduled to be in service within 2020, the main purpose of this project is to develop the country’s transport facilities for fast vehicles.
To ease the construction of this 58-km long expressway, the project owner Vietnam Expressway Corporation has divided the project into three phases: the western, the middle, and the eastern sections.

Smooth and Fully-threaded PT bars: post-tensioning solutions for bridges and viaducts

For the construction of the 3-kilometer long Binh Khanh Bridge, which is part of the middle section, Dextra has supplied smooth and fully-threaded post-tensioning bars have been delivered. These have been used in the main structure, the stay cable, as well as the bridge’s western and eastern approaches.

The six-lane extradosed bridge over the Ganga River in Prayagaraj will span for 9.9 kilometers, with the main bridge covering 3.84 kilometers and the approach segment covering the remaining distance.

The 3.84-kilometer stretch would include 67 pillars and 17 pillar foundations. Also, of this 3.84 km, the span of 860 meters will be extradosed bridge, and the rest will be a precast segmental bridge with a span of 50 meters.

Dextra supplied 20,000 Sonitec tubes, an easy-to-assemble and time-saving tube solution used for the CSL (crosshole sonic logging) testing of foundation piles to determine the structural integrity. The tubes were installed in piles that were 30 to 36 meters deep and had a diameter of 1.2 meters.

The bridge will start from the Pratapgrah road, gain height to over cross the existing Y-junction (going towards Lucknow) and would then cross the Ganga from Kacchar area spanning over Beli village before ending at Stanley Road. It is expected to be in operational in 2024.

يعد جسر ستورستروم الجديد بمثابة شهادة على التزام الدنمارك بتحسين البنية التحتية للنقل وربط جزر البلاد بشكل أكثر كفاءة. يمتد هذا الجسر فوق مضيق ستورستروم، وسيحل محل جسر ستورستروم القديم، والذي كان بمثابة حلقة وصل حيوية بين جزيرتي زيلاند وفالستر منذ عام 1937.

تم تصميم جسر Storstrøm الجديد ليس فقط لاستيعاب حركة مرور المركبات ولكن أيضًا للمشاة وراكبي الدراجات. تم تصميم هندستها المعمارية وهندستها المبتكرة لتقليل وقت السفر وتحسين السلامة وتوفير رابط موثوق بين هاتين الجزيرتين الدنماركيتين الرئيسيتين.

قامت شركة Dextra، بفضل خبرتها في مجال حلول الإنشاءات الهندسية، بتوريد 120.000 من قارنات التوصيل والقضبان الرأسية من Rolltec لربط أقفاص تقوية الركائز. تعتبر هذه المكونات ضرورية لبناء أساس الجسر، مما يضمن ترابط الركائز بشكل آمن لدعم الوزن الهائل والقوى التي سيواجهها الجسر خلال حياته.

بالإضافة إلى مساهمتنا في أساسات الجسر، قمنا أيضًا بتزويد قارنات التوصيل Unitec لتطبيقات الإصلاح، وربط قضبان التسليح المثبتة بدون خيوط. بفضل مساهمات Dextra، سيكون هذا الجسر بمثابة شريان حياة بين زيلاند وفالستر للأجيال القادمة، حيث يربط الناس والمجتمعات والفرص.

The Nanay Bridge is a 2.2km bridge crossing the Nanay River, north of the city of Iquitos, Peru.

The bridge will connect the district of Bellavista on the right bank of the Nanay River with the district of Santo Tomas on the left bank.

With a population of almost half a million people, Iquitos is the largest city in the world that cannot be reached by road – tucked in the Peruvian Amazonia jungle, it is currently accessible only by river and air.

Thanks to this project, the city will finally be connected with the rest of the Loreto Region.

The main structure is a cable-stayed bridge with a main span of 242m and total length of 424m. The approach structures are 1.2km long on the right bank of the river, and 320m long on the left bank of the river.

The bridge carries two lanes of traffic and two pedestrian walkways. The roadway has a total width of 12m, and each pedestrian walkway is 1.2m wide.

It uses light-weight composite steel concrete to minimize the use of concrete and to reduce loads transferred to the foundations.

For this project Dextra has supplied 100,000 Bartec couplers for rebar connection and 30,000 headed bars for shear reinforcement of the anchors.

Once completed, it will be the longest bridge in the Country.
