CROSSRAIL INFORMATION PAPER D23 – SPRAYED CONCRETE LINING

2.3 The way in which SCL will be used on the Crossrail project builds upon the considerable experience of the use of the sprayed concrete as the means of forming tunnel linings and the following measures have been developed to specifically address and mitigate the risks to reduce these to As Low As Reasonably Practicable (ALARP). These include:

04/05/2012  The Spray Concrete Lining technique will be used to build 12 km of station platform tunnels, passages, access and grout tunnels along the Crossrail route where smaller, relatively short tunnels are needed. Unlike bored tunnels which are built using a tunnel boring machine, SCL allows variation in the tunnel shape and diameter and 7.5 km of SCL tunnels will become permanent

The Build: Main Construction - Crossrail

The sprayed concrete lining method has been used extensively on Crossrail to form each of the station platform tunnels at Bond Street, Tottenham Court Road, Farringdon, Liverpool Street and Whitechapel, cross-passages between the platform tunnels, ventilation tunnels, concourse tunnels, cross-over caverns and ventilation, escape and intervention shafts across the central section of the route.

Ingenia - Cladding Crossrail's tunnels

The sprayed concrete tunnel linings for the Crossrail platform and crossover caverns for the stations were applied at an earlier stage of the project. The concrete lining created spacious circulation routes but is not an ideal final finish for the tunnels as it can be inconsistent, dusty, hard to paint and is acoustically ‘bouncy,’ causing sound to clatter and echo. The tunnels needed ...

Crossrail to promote new linings New Civil Engineer

16/12/2010  Mott MacDonald tunnel engineer Brian Lyons said that wider use of composite tunnel linings which allow load to be shared between primary and secondary linings would emerge as a result of their use on Crossrail. Lyons has worked on designs for Crossrail’s sprayed concrete lined station platform tunnels and was speaking at NCE’s Tunnelling 2010 conference last week. Exploiting this
