| Objectives | This project seeks to successfully trial an improved method to replace short lengths of metallic main in specific locations of engineering difficulty (short lengths of main that connects onto its parent main in a major road junction) in a safe, efficient and practical manner and to agree an efficient implementation strategy for the technique. The primary anticipated benefits of this project will be that Sealback II will: ; Reduction in operational risk and expenditure when replacing the cast iron tee sections. Sealback II would allow the mains located in areas of engineering difficulty to be replaced: e. g. tees under major roads and road junctions. In particular this technique delivers a solution to the requirement to replacement short length stub pipes under Appendix F of T/PM/REP2. Reduced excavation and reinstatement costs, contributing to the ‘No Dig’ targets;Reduced flow stop operations on the parent pipe and associated risks;Reduced cost associated with the insertion of replacement tees in large diameter parent mains;Enabling the replacement of mains that are not easily accessible;Reduced disruptions to the public and requirement for traffic management;Reduced damage to third party apparatus;Reduce risk associated with working in the highway and costs from lane rental;Reduced safety risk to the public due to reduced excavations;; Considerably reduce impact on the environment and minimize inconvenience to the road userReduce environmental impact by both minimizing all associated works as above including the requirement for imported backfill and landfill of excavated spoil and impact on trees;Increased reputation for minimizing disruptions. Successful field trials of the Sealback II technique for CI4" and CI6" diameter and up to 20m in length: with a stretch target of 27m. | |
| Abstract | The existing Sealback I technique for live mains transfer has several limitations in that it does not work effectively in situations where tapered pipe sections or change in pipe diameters are encountered. It is also limited in the length of main that can be inserted: furthermore obstructions to the insertion process within the main cannot be easily seen or dealt with. Sealback II is to be developed, to overcome these limitations. This project will build upon the lessons that have been learnt in deploying Sealback 1. 5 and the success of the Sealback II feasibility study which was previously carried out under the Innovation Funding Incentive (IFI) and the Sealback II design development funded under IL142. The feasibility study proposed the use of an innovative expanding sealing bag nose cone, as an identifiable solution, while IL142 developed this solution to a stage where it was ready for field trials. This project will look at the field trialing of the identified ‘Sealback II’ solution which incorporates camera technology advances, developing and recommending an appropriate sealant deployment method, and finalize a suitable implementation strategy.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
