Irrigation and canal project timelines in Northern Gujarat are notoriously tight, as concrete lining must be completed during dry seasons before water channels are reopened. In this project case study, we examine how the deployment of self-loading concrete mixers accelerated construction on the Hansapur Patan Canal Bed project.
The Challenge: Access and Logistics
The project involved concrete lining of a 3-kilometer canal stretch. Traditional batching plant delivery was ruled out because ready-mix transit trucks could not navigate the soft, unpaved canal embankment tracks. Setting up a stationary mixer on site was also inefficient as it would require manually transporting concrete over long distances, causing segregation and slump loss.
The NJP Solution
NJP deployed two **Ajax Fiori Argo 4000** self-loading concrete mixers on a rental basis, complete with experienced operators. Raw materials (aggregates, sand, and cement bags) were stockpiled at strategic intervals along the canal path.
The Argo 4000 mixers loaded the raw materials directly from the stockpiles using their front shovels, mixed the concrete to the exact design grade on the move, and discharged the fresh concrete directly into the canal bed slope. This eliminated transport delays and double-handling.
The Results
- Pouring Speed: Increased from an estimated 40 m³ per day to a consistent 95 m³ per day.
- Labor Cost reduction: Reduced layout crew size by 40% due to automated mixing and pouring.
- Timeline Saved: Completed the concrete lining 15 days ahead of schedule, saving the contractor substantial delay penalties.
"NJP's machines and operators allowed us to pour concrete continuously right at the point of deposition. The equipment uptime was exceptional." - Site Supervisor, Hansapur Canal Project.
