The german page about trams in Cairo is much more complete than the page in english : http://de.wikipedia.org/wiki/Stra%C3%9Fenbahn_Kairo

Grande Poste - Martyr's pl. extension works

Martyr's pl. station

Mar 3, 2015 | Algiers, Algeria

Quote:
With a length of 144 m and a width approaching 23 m, the "Place des Martyrs" metro station boasts some very impressive dimensions. In addition, the entire 1.7 km long extension of the Algiers metro system runs under historic ground. For this project, an international team of PERI engineers designed economically optimized tunnel formwork solutions, tailored to meet the varying requirements.

The northernmost, but also most central as well as closest-located point to the harbour area, of the extensive metro expansion measures is the "Place des Martyrs" station. The arch-shaped stop is 144 m long and 23 m wide – and will be one of the largest subway stations in the world after completion. The construction project is part of the ambitious infrastructure development plan designed to expand the current almost 9 km long, single-line metro network in the Algerian capital to a total of 55 km in length and featuring three lines over the next 10 years. The modern metro system will help to reduce the daily traffic jams and increase the mobility of the city´s residents. With a population of more than 3 million inhabitants, Algiers is also the most important transport hub in Algeria.

2 cross-sections – 1 formwork carriage


"Place des Martyrs" features two different cross-sections. The imposing arch width of 23 m in the middle section, tapers in the northern and southern directions resulting in 16.50 m widths respectively. PERI engineers developed a formwork carriage construction on the basis of the VARIOKIT engineering construction kit in order to be able to cost-effectively realize both cross-section variants whilst using the same system components and formwork segments. Furthermore, special attention was paid to the design of the bracing during the planning phase as the concreting cycle length of 5.10 m is relatively short.
Based on the VARIOKIT modular construction system, the PERI formwork carriage solution is ideally suited to meet all project requirements: user-friendly as it can be hydraulically operated with a control panel, cost-effective due to the rentable system components, and can be quickly assembled or adapted by means of standardized bolted connections. Supplementing the VARIOKIT formwork carriage construction is a PERI UP working scaffold. This has been optimally adapted to match the cross-sectional geometry of the arch andensures the rapid and safe execution of the waterproofing and reinforcement work in advance of the tunnel formwork carriage.

The VARIOKIT modular concept


VARIOKIT is designed to accommodate the known load combinations of the tunnel, bridge and high-rise building construction. With standardized, rentable system components and site-compliant connection means, supporting formwork can be cost-effectively realized and geometrically adapted to suit the structure. For the construction of traffic-related structures with low usage, in particular, the rapid availability of materials as well as the quick and easy assembly results in enormous time and cost savings. Moreover, PERI VARIOKIT project solutions together with the corresponding equipment options can be tailored to fulfil the respective project requirements.

Historical challenge


Currently, the African metro project includes the construction of the twin-track tunnel along with the development of two metro stations. To the north of the "Tafourah" end station, located close to the palatial Grand Post Office, Line 1 is being extended by a total of 1.7 km with the addition of the "Ali Boumendjel" station (Emir Abdelkader Place) and the "Place des Martyrs" station. Construction work is being carried out within the city centre which features numerous mosques and palaces as well as under the historic old town (Kasbah) which is a UNESCO World Heritage Site. This has presented a major challenge for all project participants.

Comprehensive tunnel formwork solutions


The formwork and scaffolding solution for the entire construction project was developed by a team of PERI engineers from Algeria, Portugal, Spain and Germany. A total of four tunnel formwork carriages are being used: in addition to the VARIOKIT formwork carriage construction for the "Place des Martyrs", a second project formwork carriage with a 9.30 m radius is being utilized for the realisation of the "Ali Boumendjel" intermediate station. Two other project-specific tunnel formwork carriages are being used for the construction of the 1,450 m long tunnel with its 4.50 m radius. This means that almost 10 m reinforced concrete tubes are being formed and concreted using mining techniques on a daily basis.

THE THREE MOBILE OPERATORS EXTEND THEIR NETWORKS INSIDE THE ALGIERS METRO



The GSM network was officially launched on Thursday, in the subway of Algiers, in the presence of the Minister of Transport, Boudjema Talai and the Secretary General of the Ministry of Post and ICT. Thus, travelers can receive and EMMETRE, starting today, phone calls on their mobile phones at all stations and trains.

This project was realized by the Algiers Metro Company in collaboration with the three mobile telephony operators, Mobilis, Djezzy and Ooredoo. The cost of the transaction was not disclosed. But if operators did not want to disclose the amount of the budget for this project, preferring instead to talk about the purpose of this operation will allow the citizen to remain connected to the wireless network wherever there is the Metro Company Algiers in turn will benefit. She will receive a fee from the operators, "was content to declare the Dg EMA, Amar Abdi.

During a press briefing at the headquarters of the EMA, after a journey made by the delegation via the metro station at the Great Fusillés station, the transport minister spoke on a range of topics including the opening of the air transport sector to the private sector. Boudjema Talai, but not against the idea of ​​open-sky, felt that this subject will be discussed at the top level. But already, it shows approval for subcontracting with the private in certain activities in ports and airports, especially in the catering, maintenance, baggage handling etc.

Taking the floor, the Director General El Djazair ARPT, the company that operates the Algiers metro, Didier Lescloupe announced the inauguration on July 5 from the line Hai El Badr El Harrach. In his speech, Didier Lescloupe also listed a series of numbers since the inauguration of the Algiers metro in 2011. He will say in this sense that the subway has traveled a distance of 5 million kilometers, transported 50 million passengers and achieved an annual growth of 14%.

Satisfied by the balance sheet, Dg ARPT El Djazair will say, moreover, that the most important is customer satisfaction. "99% of customers are satisfied by the delivery of metro and 99.78% of trains arrive on time," he was welcomed by referring to opinion polls conducted by the EMA.

No, Haï El Badr station (the current line 1 terminus) is also ground-level.
