Chennai: away from the hustle and bustle of Poonamallee High Road, in the silence of the Earth, the central Metro is one of the largest underground subway stations in the country and is being formed.
Chennai Metro Railway Co. , Ltd. has completed most of its work (CMRL)
It is preparing to open part of the station by 2018, which will connect the central Metro and Chennai airport through Nehru Park.
The rest of the station is expected to be ready by 2018
It ended almost seven years after construction began.
\"We have completed track and signal work on the upper level.
We will invite the Railway Safety Commissioner to carry out the inspection within a month, \"said a subway official.
The central Metro will be an underground transportation hub with several facilities for logistics and travel and will connect two corridors-
Located in the center of St. Thomas Hill and vashpett, you can reach Chennai Airport, Issue 45 km-1 project.
Afcons is an infrastructure company that is building tunnels for phases
1. it is also built.
The central Metro, which is 390 long, 33 metres wide and 28 metres deep, will be one of the country\'s largest three-story underground stations.
Haozkas in New Delhi is one of the deepest stations in 29 m, with six decks and majestic subway stations in Bengaluru, one of the largest stations with an area of 48,000 sqm.
As a transportation hub, the station will have facilities that are not available at other subway stations in several cities.
Commuters can walk to the top deck of the station along the entrance/exit point of the station on both sides of the road, which will be the ticket or lobby level.
The entrance will be connected to two levels instead of one built in other subway stations.
Passengers traveling by vehicle to the station can enter the station through an entrance point and head to the underground parking lot before walking to the ticket floor.
The second and third decks of the station will be the platform floors of the two corridors1.
When the second or upper level will be connected to the center with Mount St. Thomas (corridor 2)
The third or lower deck will connect waspet to Chennai Airport (corridor 1).
Pedestrians on the main roads are also easy to cross busy roads, as the station will be open with two new metro lines, which will help facilitate access to both sides of the road.
The station will also have several other functions for train operations, such as side lines, where the train can start the day\'s operation and travel to the main line in both directions and in both corridors at the same time.
Just like the shennagar metro station, Central will also have cross lines where trains can cross tracks in case of an emergency on both decks.
\"About 70% of the work has been done.
\"We will hand over the entire station to CMRL next year,\" an Afcon official said . \".
Starting with the construction of the station, this construction poses a challenge.
Extreme changes in soil formations, excavation under several heritage structures, multiple
Buildings lined with shallow foundations, rail tracks and Buckingham canals have slowed construction.
There is a thick layer of rock under a loose layer of soil under the road surface, which must be cut and covered with a curved concrete slab forming a tunnel ring.
The Concourse layer is built around different types of loose soil, while the upper and lower decks are built on rocks.
The mixed soil formation greatly reduces the average tunneling speed of the tunnel during stretching.
\"Our average drilling speed is 2.
5 m per day, with the usual average of 8-10m a day.
In the expansion project in North Chennai, we drill at 11 metres a day, \"said a CMRL official.
\"When we drill the rocks, the knives on the cutter heads of the tunnel rig are often damaged,\" an Afcons official added . \".
On one occasion, due to rock soil conditions, engineers spent more than six months digging the 300-meter-long section between Rajiv Gandhi Government General Hospital and Chennai center.
Engineers did not put more pressure on drilling the rocks because it would affect weak structures and heritage buildings on the road.
\"We conducted extensive soil surveys and advanced soil stabilization methods along the tunnel route ahead of the rig as a precaution against damage on the road and under the road surface, an official said.
