The tunnelling phase of the Green Line for the £6.25bn Riyadh Metro in Saudi Arabia has been completed on June 2016.
Green Line (Line 5) is one of the three lines being constructed by the FAST consortium-one of three international consortia commissioned to build the Riyadh Metro projects’ six lines. The FAST Consortium is commissioned to build the Yellow, Green, and Purple lines-33 km of viaducts, 22 km of underground and 9 km of at-grade.
The Green Line runs underground within a bored tunnel along King Abdulaziz Road, one of the main arteries running through Riyadh. The length of the line is 13 km and features 11 deep underground stations as well as two transfer stations with the Red and Blue lines.
The event marked the kick-off of construction by Alstom of track works, an important milestone for the project. The works will commence within an at-grade section of the Yellow Line, and will be the first tracks to be installed throughout the Riyadh Metro project.
Grouted tieback anchor is an ideal anchor system for metro construction. It is a safe, reliable, efficient and environmental solution to be used for metro projects. Grouted tieback anchor has the advantage of fast drilling and placing due to drilling, anchor installation and grouting in a single operation. With the development of geotechnical anchoring technique, it has been used for more and more projects, including railway, highway, mining, water conservancy projects, slope stabilization and building foundation.
