Tehran city Surface water collection network- The tunnel of arterial channel No. A of Sorkhe Hesar stream

Project  specification:

Collection and transmission of raining water and other sources of surface water in north east of Tehran city is main goal of this project. Since the project is located in a high traffic zone in north east of Tehran, the only solution for possibility of execution of the project was just use of tunneling techniques instead of trenching. Execution of tunnels in depth of 8 meters (6 to 11 meters) and installation of RC pipes are the main activities of the project.

The total length of project is about 5 Km and RC pipes with sizes of 1000 mm up to 2000 mm are installed in mentioned tunnels; accordingly the numbers of 100 manholes are executed in the stream line.
