You could find two different types of auger flights that are made with a continuous wound flight and sectional pressed flight. Continuous flights are made with the help of a custom-designed winder that goes up to around 12-inch diameters. This process involves wrapping a piece of flat bar material that is 20 feet long around a mandrel to create continuous flighting. Sectional flights could be larger ranging up to 60 inches and instead of one long continuous flight, it is made of individual segments that are welded together. The customised winder is not something you would find anywhere else in the world. It is a custom piece of equipment that we have developed over the years. The winder is only used for the smaller diameter wound continuous auger flighting. You could get a Flight Auger or spiral flight if you reach out to the right agencies.
The core is a piece of DOM steel tube and is what the wound flight is welded to. When a pressed flight is being made, it is important to ensure that the various sections of the auger are pressed with straight ends forming an overlapping joint for them to properly fit together. the flight acts as a conveyor when it is inside a casing as it rotates and moves the material down through the casing. As you come to different segments of the auger you want them to time so that any dirt or soil that is being rolled through does not get caught on an auger out of time and thus could seamlessly pass between the two ends of the auger for a continuous flow. Timing of the auger flight is extremely important so that there is a smooth transition from the auger to the auger. This is why it should be made sure that each auger is timed, which means that the end of each auger flight is always going to be created to match up with the next section of the auger.
How does it Work?
The various sections of augers are made with male and female hexes on each end of a segment and are pinned together making the timing line up. Using a male and a female connector is for two auger flights that are pinned together.
Certain products would have hardened male and female hexes when the inner piece is stronger than the exterior like putting a piece of steel in plastic over the time the softer female would start wearing something that is similar to a stripped bolt and end up spinning out.
Continuous flight auger piles (CFA piles) are reinforced concrete elements executed in loco, in holes excavated using proper machinery. CFA piles are a type of bored piles in which a helical auger is used to dig holes and incorporates a tube that allows the concreting while the auger is removed, after the excavation of the hole. The execution method for this type of pile would allow the excavation in hard soils and is especially suitable for urban environments, as the vibration and noise levels are minimal.
