How the DrainUpGrader works
The DrainUpGrader is an attachment for regular excavators and makes erosion resistant drains. It does this by using an in situ method. With a continuous motion, the DrainUpGrader excavates, stabilises, and compacts the existing soil. This allows it to create new drains with a significantly higher production rate compared to conventional drains, for a fraction of the cost.
To explain this procedure in more detail, we will describe the 4 key components of the DrainUpGrader below.
Drum Cutter
The Drum Cutter is a cylindrical cutting device that will excavate the drain. The teeth on the drum will allow it to break up and excavate any soil type. The excavated soil is transported through a shaft and deposited next to the drain.
Mixer
The soil will need to be stabilised with additives to allow for the drain to be erosion resistant. The additives are supplied through a pipe and mixed with the remaining soil with a mixer. This will make a homogeneous soil mixture.
Driving Mould
The final step in making the drain is to compact the stabilised soil. This is done with the Driving Mould. It compacts the soil by vibrating and its divergent shape. What remains is a smooth, erosion resistant drain.
Digging Chain
The DrainUpGrader is also equipped with a Digging Chain. This device makes a narrow trench in the soil in which the cable layer can deposit telecom cables.
