Darvazeh Dowlat Underground Station
General Technical Specification of the Project:
Tehran underground K1J4 station is an intersection station at which lanes 1 & 4 meet, with about 11000 m2 substructure area, is one of the biggest stations in Tehran. The station has been built in 5 levels including shopping mall, office floors, ticket hall, air handling plans, and platform and under platforms. In the final designs, different kinds of false ceiling were used for having a better diversity.
Roof and Wall Gutter:
One of the important problems in underground areas is water infiltration into from the water surface . To solve this problem, we used a kind of gutter from galvanized sheet between structure and final finishing and water is driven out by waste water network. To cover these gutters, we installed stones on the walls by drywall method.
Mechanical and Electrical Installations:
Like other underground stations mechanical and electrical equipment and installations were special in terms of safety and convenience such as incombustible cables, dust-proof and anti humidity lights, dry and wet firefighting systems, telecommunication system, CCTV system and etc.
