PARIS METEOR

A new 7.5km Meteor metro line is now being developed in Paris. This article describes the construction of the 1655m section of this line. It has three new stations: Bercy, Dijon and Zac de Tolbiac. The three contracts for this section cover: (1) the 857m long tunnel from Bercy to Dijon; (2) Dijon station; and (3) the 669m tunnel under the River Seine from Dijon to Zac de Tolbiac. The 7.3m wide tunnel will take two metro tracks. Access to the tunnels is via a 30m deep, 6m long and 5m wide shaft on one side of the Seine and a similar shaft on the other. Most of the tunnelling is through a layer of moderately hard fissured limestone, below alluvial material which is itself below the water table, as it is not practicable to use a tunnel-boring machine near the Seine, the tunnel is being built by a 62t AC-Eickoff ET 210-Q roadheader, fitted with 1080mm transverse heads. A placing device, fitted to the roadheader, is being used to insert steel arch supports for the tunnel roof. Water is being pumped from the tunnel into the Seine continually, through a new drainage system. The line will cross the Seine in a submerged tube, consisting of four 34m long caissons. Eickhoff roadheaders are also working on the Eole RER line, where several approach tunnels are being built to access a massive 220m long and 60m wide underground cavern that will contain a new station. The main tunnels will be about 32m underground, in a limestone layer.
