[info]Further spacing out of the pile centres produce soldier pile walls. Based on a competent geotechnical profile, such that the piles stand alone and panels or arches between the piles transfer loading to these soldier piles provide the shoring restraint.[/info]
Ausipile can design a system for your next project this type of wall is not suitable for high water table installation as it is very hard to install with out major dewatering system present.
[info]When the piles no longer need to intersect based on the geotechnical profile it allows a small ‘gap’ between the piles that can be closed, if necessary, during excavation.[/info]
Bored Piles are circular piles made of concrete and steel being installed in the soil by various drilling
methods.
When the piles are side by side and not linked together they form a retaining wall for excavation pits or terraces. Depending on the application of the contiguous pile walls, the length, diameter, material, formation, and placing of the individual piles can be adapted to meet many different requirements.
This can be done via:
Each one has it own advantages and disadvantages.
[info]The premium piled wall solution for retention structures. Secant pile walls require a specific technique and quality control to ensure the correct secant interlock for water retention and positional tolerances at depth.[/info]
Ausipile will make sure our design meets the requirements of your project, and deliver the best results given budget and time frames.
We can do up maximum of 827mm diameter and depth of 30 meters.
The main advantages of Secant Pile Walls are:
[info]Bored piles drilled using either permanent or temporary casing to prevent collapse.[/info]
[info]Micro piles also known as mini plies, pin piles, needle piles or root piles are small diameter drilled piles. They offer a viable alternative to conventional piling techniques particularly in the following conditions:[/info]
[info]Bored Piles are drilled under a head of slurry – either bentonite or polymer to mitigate collapse. Underslurry piles are ideal for deep foundations up to 68 meters deep using slurry to support the earth as the pile is being drilled.[/info]
The diagram below shows the standard procedure of casing installation, excavation, cleaning of the slurry; then installing the reinforcement cage, pouring the concrete and extracting the casing.
[info]FDP (full displacement piles) has many benefits of driven piles without the disadvantages of noise, vibration, joints and waste.[/info]
FDP are a type of reinforced concrete pile that are built in situ. This technology combines the advantages of driven (displacement piles) and bored piles (piles without displacement).
Despite being executed in situ, along with bored piles, they are classified as displacement piles due to the fact that, throughout its execution, it exists the soil consolidation around the pile, as a result of an horizontal displacement imposed 2 by the drilling equipment. This compaction intends to improve the soil characteristics thus increasing the available area at the time of the loading application.
This technique uses a specific drilling equipment which is inserted in the soil by virtue of the application of a torsional movement, applied in the auger rod, and a downward thrust. The main difference between this technique and the remaining techniques is the drilling tool configuration that causes an horizontal displacement during the drilling process due to a zone with a greater diameter.
Drilling with the displacement system – full displacement piles.
[info]This is a common and cost effective technique in less stable ground conditions. There are several advantages to using the CFA piling method. These include:[/info]
[info]This type of pile is the most straight forward of the auguring techniques. However drilling rates and geologically specific tooling determine the quality and cost effectiveness of this.[/info]
Ausipile can drill up to 2.8 meter in diameter and up to 68 meters deep if required in ideal conditions if required please feel free to contact our team at Ausipile to see what will best fill your needs.
[info]This is one of a most technically advanced techniques and is one of Ausipiles premium products and has been for some time.[/info]
