ballast foundation damage
This railway system in Shandong, China, suffered from ballast foundation damage caused by constant rainwater infiltration into the sub-base. Heavy machinery could not be used because the train could not be stopped, re-routed, nor the schedule changed to allow for repairs.
The solution was to engage hundreds of labourers to manually lift the track during the intervals of passing train. The collection pipes with belt were prepared in advance. Ballast was excavated to insert the Capiphon™ belt. Because the Capiphon™ belt is flat, and doesn't require deep trenching, the rails did not have to be lifted far.
The ballast was replaced immediately.
After the installation, water ran freely from the Capiphon™ under the railway line. The water was collected and was seen to be free from silt and other contamination.
Serious Alternative to Ag Pipe
Ag pipe is also called aggie, agricultural pipe, ag line etc. Capiphon also out-performs slotted pipe.
