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.
