MRT Pink Line Project

Bore Piles construction in Thailand

MRT Pink Line Project

Bangkok’s 34.5-kilomter Pink Line is one of the city’s mass transit lines planned with the Mass Rapid Transit Master Plan to connect areas between Nonthaburi Province and Min Buri district. The Pink Line system was allocated to be part of a minor mass transit system with regards to the elevated straddle monorail.

Project Responsibilities

Bore Pile:

  • Dimensions: 1-1.8 meters x 40-57 meters

  • ± 400 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.
