Commonly referred to as Ag-Pipe, Ag-Line or Draincoil, Slotted
Agricultural pipes - also called ag pipes, soakage drains, agi pipes, ag lines, slotted drainage pipes or french drains - are underground plastic pipes that help prevent damage to buildings by removing water from the soil.
The purpose of the agi pipe is to drain away any water that is in the ground. Agg pipe slotted pipe comes in rolls. Groundwater or surface water that seeps into the trench falls through the rocks and is carried away by the slotted PVC pipe.
Ag Pipe has a number of applications at home, at the farm or at a construction site and is available in 65mm and 100mm - 10m, 20m, 50m and 100m rolls.
AG line or also known as agricultural line is a drainage pipe that has holes in it to help disperse water with in a retaining wall or somewhere where water can potentially pool such as under a house, in a sand pit, or at the bottom of a hill. It works by having holes in it.
Pipe depths are typically a minimum of 700mm to 1200mm for drainage in soils growing pasture.
Available in a range of sizes including 50mm, 65mm, 100mm and 160mm in slotted with filter sock, slotted and un-slotted. Corrugated Ag Pipe comes in coil lengths ranging from 10m up to 200m and each coil is fitted with a Coupling.
The most common standard diameters are as follow: 0.5 inch (15 mm), 0.75 inch (20 mm), 1 inch (25 mm), 1.5 inch (40 mm), 2 inch (50 mm), 3 inch (80 mm), 4 inch (100 mm), 6 inch (150 mm), 8 inch (200 mm), 10 inch (250 mm), 12 inch (300 mm), 14 inch (350 mm), 16 inch (400 mm), 18 inch (450 mm), 20 inch (500 mm), 22 inch ...
Re: how to attach AGI pipe to storm water drain
Generally, you'll need to cut a bit of Agi pipe to go in between the T and the adapter. A good example is the Vinidex 100 x 90mm PVC Stormwater Draincoil Adaptor one side clips onto the Agi pipe the other side allows you to fit a 90mm PVC fitting.
If your agricultural lines are connected to your roof downpipes, water can flood back into the agg line and flood the trench that's meant to be collecting water every time it rains. The water will soak into the ground and can affect your house footings.
For the ultimate drainage system this Socked ag-pipe should be used in conjunction with a geotextile fabric. Geotextile fabric is a fabric that prevents silt migration, it should be used in a u shape behind the retaining wall and folded over the top of the gravel to prevent silt from entering into the gravel.
Pea gravel is one of the best materials for landscape drainage because its small size allows for outstanding drainage. These rocks are only about ¾ inches in size. Pea gravel is available in a variety of shades, including brown, grey, blue, and red, making it a good choice for a number of different landscapes.
Screen or Slotted pipes are used for casing in the groundwater section to allow water to enter the well. These pipes can also be used to provide soak-ways for the stormwater/rainwater to infiltrate back into surrounding areas. Thus, we can recharge the groundwater and prevent the runoff of rainwater.
To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159. For example, if the circumference is 12.57 inches (319 mm), you would divide by pi, and get an outside diameter of about 4 inches (100 mm).
The Measure app uses augmented reality (AR) technology to turn your device into a tape measure. You can gauge the size of objects, automatically detect the dimensions of rectangular objects, and save a photo of the measurement.
PVC Pipe Sizes in Australia
25mm or 1 inch pressure PVC pipe (in this case, class 12), has an internal diameter of 30mm. The external diameter of the pipe is 34mm. 20mm or ¾ inch pressure PVC pipe (in this case, class 12), has an internal diameter of 23mm with an external diameter of 27mm.
Across Australia, the accepted standard S-Trap distance is 140mm, but it's not uncommon to find dimensions of up to 180mm – and even as much as 240mm in some cases.
When it comes to measurement of pipe, it is measure by the inside diameter, often called the nominal diameter. Nominal Pipe Size (NPS) is a North American set of standard sizes for pipe. The term nominal refers to pipe in non-specific terms and identifies the inside diameter with a non-dimensional number.
Behind the wall, a drain system must be placed to prevent water from pooling and undermining the structural integrity of the wall. The first step in this process is the placing of agi pipe covered with appropriate geotextile fabric and backfield around with suitable aggregate.
In this instance, it's used to protect the backfill from soil and silt entering, which would stop water from passing through it freely. A geotextile sock should also be used around the drainage pipe to prevent debris from clogging holes and limiting its performance for retaining wall drainage.
The aggie pipe is put there to drain away any water that is in the ground. Groundwater or surface water that seeps into the trench falls through the rocks and is carried away by the slotted PVC pipe. placing a slotted PVC pipe in the bottom of the trench. The pipe is, often protected by a geofabric.
