MRT Blue Line ExtensionOverview
The Metropolitan Rapid Transit (MRT) is Bangkok‘s public transport system, opened in 2004. Currently, only the Blue and Green Lines are in service. A Purple and a Red Line are under construction. In total ten new lines are planned to be constructed by 2029.
The existing MRT Blue Line is being extended by a total of 27 km of railway track. Of this total, 5.4 km is underground and 21.5 km is elevated.
The elevated structure consists of a twin-track viaduct of precast segmental box girders. The structure is continuous with spans of up to 35 m and supported by a row of single columns beneath the middle of the road. The project is expected to be completed in 2016.
mageba supplied 979 RESTON®POT bearings for the 11 km-length of elevated tracks from Taopoon to Tha Pra, Bangkok. Four of the bearings, supporting the structure over the Chao Phraya River, each have a load-carrying capacity of 10,000 kN.
All RESTON®POT bearings are equipped with a special POM seal developed by mageba. This POM seal is considered by many to be one of the best in the world in terms of durability, service life and reliability.
The steel components of the RESTON®POT bearings are corrosion-protected with the mageba C4 protection according to ISO 12944.
