Old Oak Common works start

摘要

Old Oak Common has become the first High Speed 2 station where construction of permanent structures has begun. Transport Secretary Grant Shapps has approved the start of procurement for a 1.8km-long underground diaphragm wall around what will become the station's underground box, where six HS2 platforms will accommodate trains serving the Midlands and the north of England. The work had been expected to start in April this year - hopefully, the Secretary of State won't have to authorise every component of HS2 station building work! To form the HS2 platform box, piling rigs will be used to install 160 reinforced concrete columns inside the diaphragm wall to support the structure. Following the first phase of construction to create the 750,000 cubic metre box, work on the eight overground platforms on the existing network will begin. More than 1,600 concrete piles will be installed into the ground on which the station superstructure and overground platforms will sit.
