The Doha Metro project is a planned rapid transit system in Qatar’s capital city. It will consist of four lines and include 100 stations, spanning a length of 215 km. It will be an integral component of the larger Qatar Rail network, which will include a long-distance rail for passengers and freight, linking Qatar to the Gulf Cooperation Council (GCC) countries, and Lusail City’s local Light Rail Transit (LRT). The Doha Metro is developed by Qatar Rail and three of the lines are scheduled to be completed by early 2020. The fourth line will be completed in the second phase of the project.

The first-stage project includes 37 stations and will be finished in 2020. The second-stage project includes 72 stations and will be finished in 2030. All stations will show vault reflecting traditional Islamic architecture, which combines modern high-technology with traditional style. 

As the host of 2022 World Cup, Qatar’s underground and ground engineering is under construction. Engineering security is more important. As a high-efficient supporting method, self drilling anchor system (sistema de perno autoperforante) has different sizes and specific tensile resistance and yield force. Self drilling anchor bolt (Anclas autoperforantes) combines drilling, grouting and anchoring together, can be cut according to site construction conditions, after completion, it will enable people to move smoothly and comfortably.
