In order to progressing the Contract Package CP101 of the Metro Manila Subway Project, Terratec has installed four continuously advancing tunnel conveyors.
Linking Mindanao Avenue in the northern part of Metro Manila to Western Bicutan in the south, the conveyors is going to play a vital role in the construction of the 33.1km-long subway section.Being deployed for CP101, the four tunnel conveyors are now in place across two key sections. While C09 and C10 operate between the Metro Manila Subway Depot and Quirino Highway Station, serving the alignment from North Avenue Station to Tandang Sora Station is up to C11 and C12.
With 1.85km-long, the conveyor system C11 completed its site acceptance testing on March 28, whereas this conveyor along with its C12 counterpart, is due to support TBM3. For handling the challenging ground conditions, it will operate at a capacity of 225m³/hour.
With the aim of providing the project’s complex requirements, four-system configuration is designed and the first two conveyors (C09 and C10) have completed their service supporting TBMs 1 and 2, while the newly accepted C11 and its counterpart C12 will soon be put into operation.
Involving hydraulic tensioning systems, widened roller sets, as well as Terratec’s patented advancing tail piece with active hydraulics to maintain optimal performance through curves, the new conveyors C11 and C12 feature specialised adaptations for Metro Manila’s mixed geology. These systems will help manage the estimated 1.2 million m3 of spoil expected from the CP101 section alone.
Construction of the Philippines’ first underground railway system for the Department of Transportation is undergoing by the Shimizu-Fujita-Takenaka-EEI Joint Venture.
The scheduled time duration for completing tunnel excavation is almost eight months and 2028 is the planned date for inauguration of Metro Manila Subway, while it will carry an estimated 370,000 passengers a day.
