Installing Poly-Pipe
Materials required for poly-pipe installation include
Tractor with furrower tool and unspooling bracket
Poly-pipe rolls
Pump or valve for connection
Agriculture Pipe |
Shovel
PVC connectors (if more than one roll is used)
Hole puncher with plugs
Prior to poly-pipe installation, fields should be leveled. Poly-pipe should be installed only on flat surfaces or down-hill, never up-hill. A minimum of 6 inches of wa-ter head (water surface height above the pipe) is required for poly-pipe use.
Poly-pipe installation steps are as follows:
1.Open the box containing the poly-pipe roll and check pipe condition.
2.Use a furrower to dig a trench (Fig. 1). (A furrower is a V-shaped cutting blade with wings that deflect soil upward and away from the center point of the V to form a ridge or furrow.) The furrow should be deep enough to accommodate about 50% of the poly-pipe’s diameter and 100% of its width to avoid any rolling to the side. The trench should be built up to an elevation slightly higher than that of the irrigated furrows to avoid water return. If the field block is curved along its edge, the curve should be no sharper than 70o, preferably with an 8-foot radius.
