Restoring 500 metres from Tringford Pumphouse, through the rebuilt Little Tring Bridge, to 200 metres past the proposed winding hole. The diagram below shows the Stages of Phase1, the wall section numbers and the completed sections. Click on one of the stages for pictures and more information about each stage:
Stage 1 Construct the towpath wall from the end of the tip infill to a point clear of the bridge contractor's working area west of Little Tring Bridge and restore the towpath. NB. The end of the construction will have to be clear of the winding hole and go at least 50 metres past it to enable a temporary bund to be constructed within the new channel prior to re-watering.
Stage 2a Construct the offside wall from the winding hole to the end of phase 1.
Stage 2b Construct the offside wall from the bridge to the winding hole.
Stage 3 Drain the stop lock at the Tringford Pumphouse and create a bund, using the unused lock gate recesses at the west end of the lock for stop planks, and refill the lock. The bund to be used as an access to keep the footpath and towpath open as required during towpath/footpath wall construction. The bund should also have a pipe/duct and valve/sluice gate for controlled filling of the restored section of canal when completed.
Stage 4 Complete towpath/offside walls west of the bridge to connect with the 14ft bridge channel.
Stage 5 Construct the towpath wall from the bridge to the stop lock during which towpath and footpath users will both use the footpath route from the stop lock to the bridge.
Stage 6 Construct the footpath wall from the bridge to the stop lock during which towpath and footpath users will both use the towpath route from the stop lock to the bridge.
Stage 7 Lay granular fill, HDPE liner and concrete overlay starting at, and working away from, the stop lock all the way through to the end of the new walls past the winding hole.
Stage 8 Construct a bund wall in the end of the new construction leaving the ends clear for eventual connection to further reconstruction.
Stage 9 Rewater the restored canal and when satisfied with the integrity of the new construction, remove the bund in the stop lock leaving the existing gates as an emergency stop.
