Anchor Bolt for Cairo Metro Line 3

"A major part of the Line 3 will be underground. The cut and cover method is being adopted to build the stations."

Quick and reliable technologies were essential for Cairo Metro. Anchor bolt, which is an advanced anchor system, is a kind of bar integrated with the functions of drilling, grouting and anchoring.SDA bolt is so especial.
It’s reliable, efficient and convenient. And SDA bolt can ensure anchoring for complex ground conditions, such as soft rock, soil layer, and fault zone, etc.

With a population of approximately 17 million, Cairo is one of the most densely populated cities in Africa. Operated by Egyptian National Railways (ENR), its railway system transports nearly 500 million passengers and 12 million tons of freight each year. Cairo Metro is the first metro network in Africa and has been operational since 1990. The network consists of two lines, and a further two are planned. With the first two lines of the Cairo Metro already completed, Line 3 is now underway to increase capacity.

Covering the central section, phase 1 included the construction of a 4.2km tunnel, five underground stations and a repository for rolling stock. The five stations, namely Attaba, Bab el Shaaria, El Geish, Abdou Pasha and Abbasia, will each be 150m-long and located at a depth between 14m and 58m. The tunnel has a diameter of 9.4m.

Phase 2 extends the underground line eastwards from Abbasiya to Al Ahram (Heliopolis). It comprises 7.2km of railway track, including 4km of underground tunnel. The line connects five stations.

Phase 3 will cover the western section of the underground line. The total length of the line will be 7.5km. It will connect Attaba station with already existing Abdel Nasser Station and a new station at Maspero, finishing at Sphinx Square Station. After a year's delay, construction finally began in 2012 and is estimated to be completed in four years.

Phase 4 will cover the eastern section of the line between Al Akram and Cairo International Airport. It will be 11km long and is expected to be completed in four years. Construction is scheduled to be completed by 2019.

Phase 5 is the final phase of Line 3, serving seven new stations.
