MRT Blue Line Extension

Overview

Project description

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 scope

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.
