Kwik-ZIP HDXT-43 spacers were used by UK infrastructure services and engineering company Amey to facilitate the sliplining of a four-pipe bundle as part of the M42 J6 Diversion Project near Birmingham Airport in the UK. Junction 6 of the M42 connects the M42 motorway to the A45 to the east of Birmingham and significant delays and congestion have been experienced by motorists due to capacity constraints. The M42 J6 Diversion Project was implemented to alleviate this congestion.
The 4-pipe bundle consisted of 2 x DN180 HDPE and 2 x DN450 HDPE pipes and Kwik-Zip spacers were selected for this project due to their ability to secure the 4-pipe bundle together, their ability to work with any pipe profile and to protect and support the bundle during the sliplining process. The carrier pipe was a 1500 mm i.d. RCP Sleeve over a length of 135 m.
Kwik-ZIP’s large range of spacers caters for a wide range of carrier/casing pipe size combinations as well as providing flexibility to deal with project alterations.
Kwik-ZIP spacers have no metal parts and are made from Kwik-ZIP’s engineered thermoplastic blend that is flexible, extremely tough and has a low co-efficient of friction.
“The spacer system was easily installed and was an excellent aid in slip lining the 4-pipe bundle through the tunnel which we had installed prior to slip lining works. An excellent product.” said Tim Lohoff, Site Manager for Amey.
