Abstract
A 183 t conical concrete roof of a cylindrical anaerobic digester tank at a UK sewage treatment works had to be lifted 150 mm to repair the seal underneath it. Due to limited space for a crane, an incremental hydraulic jacking procedure was used, with 32 bottle jacks in pockets cored out from the top of the concrete tank wall. This paper describes the temporary works design methodology, the extensive planning for risk mitigation, the practical implementation strategy and the lessons learned from using this safe and cost-effective approach.
期刊介绍：
Civil Engineering, listed by the Web of Science, is the ICE''s flagship journal. Practical and diverse in its scope, it publishes overview papers for the non-specialist on any subject relevant to civil engineering today. Topics range from landmark projects to philosophical, ethical, environmental, management and safety issues.
Peer review, copyediting, and colour publication by Civil Engineering are free. If accepted, published papers are easily found by Google search, as well as in specialist citation indexes. There is also the option of making your article open access, should you wish to.
Published authors receive a free electronic copy of their article to share with their peers. Furthermore, as well exposure to ICE''s 91,000-strong membership, published papers are promoted via our social media channels, accessing the wider civil engineering community.
It is free to submit a paper to this journal. Papers appear Ahead of Print (below) as soon as they are ready to be published. Ahead of print articles are fully citable. using the DOI system
