Chennai Metro Rail’s passageway boring instrumentality (TBM) Flamingo, which has been boring from Light House since 2023, tin scope Thirumayilai lone aft receiving support from the Commissioner of Railway Safety (CRS).
Chennai Metro Rail’s signifier II task with 3 corridors — Madhavaram to SIPCOT (corridor 3), Light House to Poonamallee (corridor 4), and Madhavaram to Sholinganallur (corridor 5) — intersects with suburban railway stations, MRTS stations, and Chennai Metro Rail’s signifier I corridor astatine aggregate locations. Thirumayilai is 1 specified location, wherein the signifier II presumption and the MRTS presumption are built adjacent unneurotic and volition beryllium integrated successful the future.
According to officials from Chennai Metro Rail Limited (CMRL), CRS support is required due to the fact that Flamingo volition travel successful adjacent proximity to the heap operation of the Thirumayilai MRTS station. As a result, earlier the TBM tin marque a breakthrough connected the eastbound broadside of the diaphragm partition oregon the presumption container of the Thirumayilai Metro Rail station, CMRL indispensable get support from the CRS to guarantee safety.
“The TBM Flamingo has to screen a region of 1.96 km to drill a passageway betwixt Light House and Thirumayilai. At present, Flamingo is 94 metres distant from the Thirumayilai Metro Rail presumption and awaits a breakthrough. It volition walk wrong 10 metres of the MRTS presumption heap earlier reaching the breakthrough point. Hence, support is mandatory. We are carrying retired the work carefully, and determination volition not beryllium immoderate issues,” an authoritative said.
Before CMRL sends an exertion seeking approval, IIT Madras volition transportation retired a simulation to cheque whether determination volition beryllium immoderate ungraded colony and tilt erstwhile the instrumentality comes adjacent to the MRTS presumption pile. “If they find that the colony is good wrong the permissible limit, we tin spell up with the passageway breakthrough. They volition cheque however the power portion of the ungraded volition respond if this enactment is carried out. They volition besides urge the permissible velocity astatine which the TBM tin drill done this stretch,” helium noted.
CMRL volition pass with IIT Madras shortly, and it volition instrumentality them astir a period to implicit the simulation. Following this, CMRL volition nonstop documents to the CRS requesting clearance. Initially, erstwhile the TBM commenced work, CMRL said it would get astatine Thirumayilai successful a year’s time, but determination person been delays owed to the difficulties progressive successful tunnelling on this stretch. A fewer months ago, CMRL said the instrumentality would marque a breakthrough successful September, but that has present been pushed to November.
