Jacked Installation of Underbridges

A presentation discussing the development and use of jacked tunnel methods for installing underbridges below existing rail and highway infrastructure while avoiding disruption and maintaining traffic movements. A range of techniques based on jacking precast units have been developed in the UK since the late 60’s, when the abutments for a small underbridge below the main rail line near Exeter were jacked into place, the bridge deck being installed in a short track possession.
 
This was the forerunner to a number of developments and projects, including modular methods to create bridge piers and abutments, box jacking and advanced support structures. The developments of the jacked deck and arch methods based on preformed lining units being jacked in on a slide path, a hybrid of deck slide and tunnelling, have greatly increased the possible clear spans, installation lengths and structure configurations. The key development issues will be presented and illustrated by reference to completed projects.

Andy Robinson is a tunnelling engineer with over 35 years’ experience in the underground facilities and infrastructure sector.  He has a tunnel contracting background and has been providing consultancy, advise and engineering services to the underground industry in the UK and worldwide since the early 1990’s.
