Micro tunneling machines were deployed to dig a tunnel into the ground in order to install the pipes. They are about eight times smaller than the usual ones used for MRT tunneling. The use of interlocking hoses also prevents misalignment and breakage of hoses.
Before the construction of the canopy, work was done to stabilize the soil and prevent water from escaping into the tunnel.
Mining was completed last December and a permanent concrete tunnel is being built.
Mining and Underlying is under the MRT Orchard station to connect the two platforms. a "great feat of engineering," said Mr. Foo.
It is made using special drilling machines, which can drill in all directions in a confined space. Work must be done gradually so as not to disrupt railway services.
Work will also be done at the Orchard MRT station to add escalators, an elevator and a stairway to connect to the TEL platform.
Detailed planning and close coordination were in progress with the 39 SMRT transport operator in order not to disrupt the operations of the station or annoy the commuters, adding that most of this work can only be done after hours of operation. connect the TEL section of the interchange station to the Ion Orchard and Wheelock Place shopping centers.
Minister of State for Transportation Janil Puthucheary, who visited the site yesterday, said that this work demonstrated innovation and ingenuity TEL
Network Expansion Singapore's railway is not without its problems, he adds.
