MRT Yellow Line Project

Bore Piles constructions in Thailand

MRT Yellow Line Project

The Yellow Line of Bangkok’s Mass Transit System, to be completed by 2022, is one of the mass transits lines planned with the Mass Rapid Transit Master Plan. The line begins at the road intersections of Ratachadapisek and Lat Phrao and ends at Samrong on the Sukhumvit Line. The Yellow Line project has 23 stations and an additional 2 proposed stations with a total distance of 30.4 kilometers.

Project Responsibilities

Barrette pile size:

  • Dimensions – 1.2 m x 3 m x 6 m

  • ± 100 piles

Project Challenges

  • Sand and clay formation

  • The Pink Line is constructed along high traffic roads, resulting in very difficult handling

Drilling Fluid Challenges
Choosing the appropriate drilling fluid for this project was a challenge due to the land formation of the project area. The drilling fluids must contain good clay inhibitors and fluid loss properties due to the need to drill into clay and sandy formations to create supporting walls for bore piles. Furthermore, the slurry had to be incorporated with a thixotropic fluid that is stable against salt contamination.
