Construction Project Mass Rapid Transit (MRT) will use advanced technology. This is a special tool for the construction of an underground (subway) named Tunnel Boring Machine (TBM).
Indonesia Mass Rapid Transit (MRT) Project
“This technology has been applied in various countries such as Singapore, Taiwan, Japan and Europe,” said Director Corporate Function of PT MRT Jakarta Eddi Santosa.
So how this machine works? This machine is a kind of robot.
Later to make a tunnel to be opened or dug up a road. Then, the TBM is inserted into it. “Obviously this would be more efficient,” he said.
TBM speed for drilling in alluvial soil, such as Jakarta can reach 12 to 15 meters per day. This tool is imported from Japan.
MRT construction plan will start from the corridor one.
The first stage will be built from Lebak Bulus to HI reached 15.5 miles in length.
Along the tracks will be built 13 station stops. Seven stations between Lebak Bulus and Block M located at ground level. Six offal, from Al Azhar to Hotel Indonesia, are under ground.
If it was completed, the path can be reached in just 30 minutes.
For the second corridor will be built from the Balaraja to Cikarang.
Transportation by train, Like electric trains, with six carriages capable of carrying 1200 passengers at a time
Tunnel Boring Machine (TBM)
Modern TBMs typically consist of the rotating cutting wheel, called a cutter head, followed by a main bearing, a thrust system and trailing support mechanisms. The type of machine used depends on the particular geology of the project, the amount of ground water present and other factors.
Behind all types of tunnel boring machines, inside the finished part of the tunnel, are trailing support decks known as the back-up system. Support mechanisms located on the back-up can include: conveyors or other systems for muck removal, slurry pipelines if applicable, control rooms, electrical systems, dust removal, ventilation and mechanisms for transport of pre-cast segments.
