What is a screw pile? A screw pile is also known as a helical pile, helical anchor, helix pier, screw anchor, helical pier, torque pile and/ or torque anchor. What is screw piling?  In unstable grounds when a traditional cast-in-place foundation system is not possible, screw piling offers a foundation support system for an ever increasing number of applications. Screw piling is the application of a screw pile into the ground. A screw pile is a factory manufactured steel foundation system consisting of a central rod with one or more helix shaped blade plates and a bracket at the end that allows attachment to a structure. The tip is cut on an angle to allow it to penetrate the ground as a pilot. The pile has 'flights' which are flat in pitch to help the pile pull itself into the ground with minimum downforce applied. With the use of an excavator and a hydraulic screw anchor drive motor attached, the screw pile is screwed into the ground to the desired compression torque...

Based in Colorado Springs, Colorado, Rusin Concrete Construction have been offering a wide range of concrete services for commercial and residential projects for the last 20 years. Earlier this year they were commissioned to excavate grade beams for a multi-unit housing project in Colorado Springs. Project Manager, Tyler Orr explained, “The total structure square footage for the slab on grade was approximately 11612sq m. Grade beams were 300mm wide and 900mm deep below the slab and were the structural component of the project in lieu of typical foundation walls. We trenched about 14km by the end of the project and shattered expectations with the excavation speed.” Rusin purchased the Digga Bigfoot XD 1200 trencher at the World of Concrete convention in Las Vegas especially for the project. It was a bit of a gamble as they had never used a Digga trencher for such an application before, typically digging with a mini excavator. However, all models in the Digga Bigfoot XD trencher...

We know that our customers are busy working long hours in often remote locations so our focus at Digga is to work closely with them to understand their needs and requirements, ensuring we supply a high quality range of machinery attachments with the best sales and service possible, going over and above. For one customer in particular, Phil Shovlin of Shovlin Plant Hire Australia time is always of the essence so when he takes time out to write an email to our head office thanking staff for their exceptional service, we know he means business! Offering specialist plant hire to the railway, mining and construction industries across the east coast of Australia, Shovlin Plant Hire recently purchased a 900mm Digga Rock Auger to fit to their 128 Komatsu Excavator for drilling work on the Roma Street railway. Phil told us “The rock augers and core barrel drills worked a treat,” and as a result of their success at Roma Street have bagged further work from their international clie...

The cutting teeth & pilot on any auger are wear parts and you can increase the life of them with the help of Digga's best practice tips. The wear life of a tooth or pilot is undefinable. They will be affected by how often they are used, how they are looked after and the ground conditions they are being used in. For example, in non-fracturable ground where the rock is reduced to a powder; the powder is likely to get caught in and around the cutting head and, acting like a sand paper, will wear away both the pocket and the tooth. In hard ground conditions such as rock over heating within the hole can cause the ground to glaze over. The heat will polish the rock making it harder and have a greater influence on the wear of your cutting heads. To assist with peak performance and longevity of the wear parts there are a few procedures that can be carried out that will help prolong the life of wear parts and increase drilling efficiency. To help increase the life of your wear...

The best way to remove spoil from your auger is to use a forward, stop, forward, stop control pattern until all the spoil is totally removed. When you have been drilling with your auger it may seem like a good idea to alternate the drive from forward to reverse to clear the auger of spoil once lifted out of the hole but, it can cause torque related stress on the drive gearbox which will lead to premature failure. If you have one of our 2-speed drive units try using the high-speed mode to flick the spoil off the auger. When you are drilling in clay you could also try wetting the auger or spray some watered down detergent on the flights before drilling. This will help the clay slide off of the unit.  For more information on the Digga drive range check out the following blog posts:  Digga tips - best practice to increase the life of your wear parts Digga tips - when to rotate picks and change the teeth in your auger Maintenance for your Digga auger drive ...
