ال جراند باريس اكسبرس is currently the largest transport project in development in Europe.

The new 200km, 68-station automated railway network consists of a ring route around Paris (line 15) and three additional lines (16, 17 and 18) connecting adjacent neighborhoods.

ستدور هذه الخطوط الأربعة الجديدة حول العاصمة وترتبط بثلاثة مطارات والعديد من المناطق التجارية. وسوف تنقل 2 مليون مسافر يوميا. ومن المقرر افتتاح الخطوط على مراحل، على أن يتم الانتهاء من المشروع بالكامل في عام 2030.

بدأ إنشاء الخط 15 في عام 2015، حيث يقع قسمه الأول بين محطة مترو Pont de Sèvres ومحطة Noisy – Champs RER A.

دكسترا was involved at that stage by providing 100,000 فورتك rebar couplers to connect the columns of the stations’ structure.

Additionally, Dextra supplied 15,000 meters of سونيتيك sonic tubes to facilitate the structural integrity testing using the CSL (Cross Sonic Logging) method, thus ensuring the homogeneity of concrete within the deep piles and diaphragm walls that are being constructed for the future underground stations.

ومن المقرر افتتاح القسم الأول من الخط 15 في عام 2020.

The Red Line is the first section of the new Light Rail system currently in development in Tel Aviv, Israel. The line will run from Bat Yam in the southwest to Petah Tikva in the northeast.

The total projected length of the line is 24km, comprising 34 stations, 10 of which are underground, including an interchange with Israel Railways services.

For this project, Dextra is currently supplying products for the construction of six of the underground stations including Bialik, Abba Hillel, Arlozorov, Shaul HaMelech, Yehudit and Allenby.

More than 200,000 Bartec rebar couplers were supplied for جدران الحجاب الحاجز and for the construction of the station boxes.

Dextra also provided 50,000m of Sonitec ST50 to facilitate the testing of the structural integrity of foundation piles using the CSL (Crosshole Sonic Logging) method.
Sonitec is an easy-to-assemble and time-saving sonic tube solution, preferred among piling and general contractors worldwide for more than 20 years.

The line is currently scheduled for completion in October 2021, making it the second underground service operating in Israel.

The Malaysian SSP Line is the second line of Klang Valley’s MRT System. The main purpose of this project is to provide a better railway infrastructure and transport system in order to serve Malaysia’s growing population.

Commuting through the heart of the Capital

The Malaysian SSP Line will connect Sungai Buloh to Putrajaya, running through the center of Kuala Lumpur and its suburbs. With its 35 stations, among which 11 will be providing connections to other lines, the SSP Line will allow commuters to transfer with ease to and from existing and planned rail lines.
The rail transit system involves the construction of more than 52 km: 13.5km of underground line and a 38.7km of elevated rail. Once operational, it is expected to have a ridership of 529,000 passengers per day.

Rebar couplers for D-wall and slab

For this large metro project, the contractor joint venture MMC-Gamuda has chosen Dextra’s popular rebar reinforcement solution بارتيك, supported by 3 sets of bar-end high-productivity equipment. Approximatively 200,000 pieces have been delivered as of April 2018.
دكسترا بارتيك have been used for productivity reasons. Couplers were embedded in the diaphragm walls surrounding the underground stations, providing horizontal connection points at a later stage of the project. After excavation, couplers are used to connect bars and start the station’s slabs.

The Ahmedabad-Gandhinagar Metro Rail Project is a new mass-transit rapid transit system in Gujarat, West India. The project is being implemented by Metro Link Express for Gandhinagar and Ahmedabad (MEGA) and aims to meet the city’s growing population while providing commuters with a better transport system.
The total length of the metro’s first phase is 39.3km, with 33.3km of elevated section and 6 kilometers underground. The metro will connect suburbs in Ahmedabad along east-west and north-south axis, and the route will also be extended to Gandhinagar in Phase-2.
The construction of the first phase, comprising 32 stations connecting the four corners of the city, has been in progress since 2015. Being expected to operate in 2020, the first trial run of the metro line is scheduled for January 2019.

Steel sonic logging tubes for concrete integrity tests

For the first phase of the Ahmedabad metro, دكسترا was involved in supplying its CSL solution سونيتيك for the 6-kilometer long viaduct. سونيتيك is Dextra’s sonic logging tube system for Cross-hole sonic logging tests. CSL method allows the contractors to verify the concrete integrity in D-walls, bored piles, drilled shafts, barrettes or in concrete piles. سونيتيك helps facilitate the assembly and installation of long tubes in reinforcing cages by its Instant Connection characteristic. Thanks to its large bell-mouth, the tubes can be easily connected seamlessly.

The MRT Pink Line & Yellow Line are elevated mass rapid transit line being built and operated by the BSR joint venture (BTS Group Holdings, Sino-Thai Engineering and Construction STEC, and Ratch Group RATCH) in Bangkok, Samut Prakan, and Nonthaburi Provinces, Thailand.

The MRT Pink Line monorail will be 34.5 kilometers long and have 30 stations. It will connect the northern districts of Bangkok and Nonthaburi with 5 mass transit lines that run along a key east-west transportation route.

The 30.4-kilometer Yellow Line will have 23 stations and will connect 6 other mass transit lines. It will provide mass transit along the heavily congested Lat Phrao road and Srinagarindra road corridors.

دكسترا was involved in these 2 MRT line extension projects by providing بارتيك splicing systems. More than 440,000 pieces of the couplers, size 16-32mm, were installed inside connecting slabs to connect guideway beams.

In addition, the contractor chose Dextra’s قضبان الرأس as an alternative to rebar hooks to avoid steel congestion in severely reinforced areas such as beam-column connections. Around 530,000 small headed bars were supplied to the construction sites.

The MRT Pink Line is expected to be operational by June 2022, with the Yellow Line following a year later.

Udhampur-Srinagar-Baramulla Rail Link (USBRL) هو مشروع ضخم للبنية التحتية من قبل السكك الحديدية الهندية في جبال الهيمالايا، وهو مصمم لتوفير اتصال السكك الحديدية إلى وديان جامو وكشمير. ويهدف هذا المشروع إلى تمكين الوصول إلى شبكة السكك الحديدية من جميع أنحاء البلاد وربط المناطق البعيدة مع بقية الهند، استجابة لرؤية رئيس الوزراء للهند الجديدة بحلول عام 2022.

وينقسم المشروع إلى ثلاثة أقسام - مسار أودهامبور-كاترا بطول 25 كم، ومسار كاترا-قاضيغوند بطول 129 كم، ومسار قاضيغوند-بارامولا بطول 118 كم. وقد تم بالفعل الانتهاء من أجزاء من الخطوط وتشغيلها.

For this massive project, Dextra supplied 3,000 sets of Self-Drilling Rock Bolts to stabilize loose rock mass after excavation.
ال الحفر الذاتي روك بولت is a bolting solution for unstable ground conditions and fractured rock formations. The loosening of the rock strata is prevented by drilling a hole in the rock, placing standard sacrificial drill bit and a hollow bar (made of steel or FRP): cementitious grout is then injected into the hollow bar.

مع اقتراب مشروع البنية التحتية الضخم من الاكتمال، سيربط USBRL جامو بكشمير، مما يفتح صفحة جديدة لنظام النقل الهندي.

Bangkok’s MRT Orange Line is one of the planned rapid transit lines of the Mass Rapid Transit Authority of Thailand (MRTA). The main purpose of this 39.5-kilometer railway line is to improve the connection between western, central and eastern parts of Bangkok, and consequently ease the Thai capital’s traffic congestion. This project is also part of Thailand’s plan to stimulate the national economy and improve the infrastructure.
ينقسم خط مترو الأنفاق البرتقالي إلى قسمين: من بانج خون نون إلى المركز الثقافي التايلاندي، ومن المركز الثقافي التايلاندي إلى مين بوري - ويضم 22 محطة تحت الأرض و7 محطات مرتفعة.

دكسترا GFRP عيون ناعمة for tunnel construction

For the Thailand Cultural Centre – Min Buri section, the contractor Joint-Venture of Italian-Thai Development and CKST opted for more than 40 units of Dextra’s turnkey solution for tunneling FRP Soft-Eye.
Being well-known for its unique cut-ability technology, Glass Fiber Reinforced Polymer (GFRP) Soft-eyes facilitates break-ins and break-outs of the Tunnel Boring Machine (TBM). This is in fact the best alternative to conventional steel reinforcement – which would require mobilization of additional manpower and equipment.

دكسترا سونيتيك for Crosshole Sonic Logging (CSL) tests

In order to verify the integrity of concrete in deep foundations, Italian-Thai Development, CKST JV and Unique Engineering have also chosen Dextra’s cross-hole sonic logging tubes – سونيتيك. These CSL tubes are available in several diameters, and have been specifically designed for easy and fast handling to accelerate construction speed. Over 30,000 tubes have been delivered to the project as of March 2022.

Complete rebar splicing solutions applied for the metro’s D-walls

To optimize the reinforcement of the Diaphragm Walls (D-Walls), بارتيك, one of Dextra’s mechanical الربط حديد التسليح systems, was installed. Thanks to its easy-to-install characteristic, بارتيك helps accelerate the projects schedule and reduce inventory as the standard coupler can also be used for Position splices. More than a million of بارتيك couplers have been delivered to the site.

Moreover, around 7,000 headed bars were applied at the end of the reinforcement bar as an alternative to hooks in congested areas of the structure.
