وصلة الدوحة (جسر جابر)

Doha Link is a marine bridge project currently being built west of Kuwait City. It will ultimately be connected to the Main Causeway Across Kuwait Bay, another sea link project north of Kuwait City, which will make the Jaber Causeway sea link, one of the largest civil engineering projects ever built in the Middle East. The Doha Link stretches west of Kuwait City. It will ultimately solve traffic congestion and offer a direct itinerary thanks to a 7.7 km bridge structure built on shallow waters across the Kuwait Bay.  

Rebar splicing solution

شاركت Dextra في المرحلة الأولى من مشروع البناء لتوفير حل تقني لربط أقفاص حديد التسليح الكبيرة جدًا التي تصنع أكوام الأساس البرية والبحرية. رولتيك® couplers for large diameter rebar (32, 36, and 40mm) were used for the connection of cages and piers. Two grades of rebar are used across the project: ASTM Grade 60 and Grade 80. Rolltec is compatible by design with the higher ASTM Grade 80; the same couplers may be used on all applications, simplifying stock keeping. In addition, smaller diameter couplers for rebar 12mm and 16mm were used for the superstructure and the footing of light poles. One of the main advantages of Rolltec for remote projects is its very light machine setup. Rolltec is supported by a single one-man machine, offering a high level of productivity. Because the equipment is relatively small and the rebar preparation efforts were taking place simultaneously on both sides of the sea link construction, Dextra dispatched up to 4 machines on each side of the project to support the piling efforts.  

محلول أنبوب سونيتيك

With large piles of 2.5m diameter and 60m depth on average, it was compulsory for GS E&C to conduct sonic logging tests to examine the integrity of concrete piles, requiring the installation of 8 tubes in each cage. To achieve very long tube length and optimize cage preparation output, Dextra سونيتيك was the preferred choice of the contractor. Thanks to its lightweight and unique Push-Fit® connection feature. Sonitec provides enough flexibility during the cage construction, lifting, and assembly of the cage and removes the need for additional time-consuming welding operations.
