Boring Piles
Introduction
Welcome to a crash course about boring piles! Bored pile, as its name implies, is a type of concrete foundation pile that is made by forming holes in the earth. This post will explain the installation process of these piles and their advantages for construction projects.
We’ll also explore how Vxcel Piling can help you get an intuitive understanding of bored piling projects with its expertise and quality assurance processes. So read on to learn more about boring piles today!
Installation of Boring Piles
Boring Piles are typically installed through the usage of unsupported piles, supported piles with permanent or temporary casing.
Unsupported piles
Unsupported piles are constructed by drilling large holes in the ground, filling them with concrete and leaving without additional supports. These piles require careful installation procedure which includes strict quality control of materials used for construction.
Unlike supported piles where drilled walls provide stability during excavation, unsupported pile requires excavators to exercise more caution when drilling in order to prevent collapse or buckling.
The advantages of using unsupported piles instead is its ability to resist lateral movement caused by soft soil conditions better than supported piling systems – they also reduce costs due to low labour requirements compared to other forms of piling techniques such as driven piling or caisson walling methods.
Supported piles
Supported piles are an efficient and reliable approach to constructing a bore pile. It involves installing permanent or temporary casing in the ground that extends around the circumference of the drilled hole to provide temporary stability during excavation.
To ensure even integrity, concrete is poured up against the casings and pressure is applied until it cures. Supported piles create a tightly sealed void within itself, allowing for deep excavations without concern for collapse or soil separation from surrounding materials due to its closed nature of construction.
This type of bored pile provides greater control over structural capacity as well as improved bearing pressurization compared with unsupported piles, making them ideal for heavy vertical loading projects such as shear walls or bridge abutments among other civil-engineering applications.
Permanent casing
Permanent casing is essential for the installation of boring piles, providing support during the bore and maintaining stability in unstable soil conditions. It consists of steel or timber tubes that are placed inside the pile bore before pouring concrete to form a pile.
The permanent casing can be used with both unsupported piles and supported ones; in unsupported piles, it provides support from within while distributing loads outwardly, while in supported piles, it helps guide and steadies the auger during piling.
Permanent casings going deeper than necessary may be avoided due to their high cost – short casings are used instead without compromising safety measures – which make lower depths particularly vulnerable.
Temporary casing
As a critical part of the installation process for boring piles, temporary casings play an important role in providing support and stability. They are installed by piling rigs to provide support during the construction, as well as aid removal of pile arisings which are the ground and rock materials removed from the borehole.
Commonly used for deeper projects with unstable soil conditions, segmental casing can be temporarily or permanently employed depending on project requirements. However it has its own limitations such as being limited in depth; usually around 6-7 meters due to difficulties in physically extracting after use.
As well as acting mechanically to maintain hole integrity, they give quality assurance through keeping material particles inside rather than falling back into excavated zones when using augers.
The difficulty that can arise is dependent upon diameter size but for most cases this should offer smooth running operations if correctly implemented according to Vxcel Piling standards.

Advantages of Boring Piles
Bored piles are an effective foundation solution for all types of construction projects, offering stability and high load-bearing capacity. Bored piles provide greater lateral play resistance against soil or water pressure compared to other pile types, allowing them to penetrate soft, compressible, or swelling soils and reach suitable bearing material.
They have the potential to be extended to any length which is required by the project.
In addition not only do bored piles offer a stronger foundation but they also cause less disruption when being installed since they create minimal vibration and noise without the need for digging up surrounding terrain – this makes them ideal where vertical structures or adjacent areas are present.
This type of piling does come at a cost however typically it works out cheaper than hand excavation or alternative methods as there is no permanent casing required usually just temporary while the pile shaft is created making it faster too.
Understanding Boring Piles with Vxcel Piling
Vxcel Piling provides quality assurance and insights on common uses, as well as a comprehensive process for the installation of bored piles.
Common uses
Boring piles are commonly used in various construction projects for structural foundations of buildings, bridges, piers and docks. They offer advantages due to their ability to increase the bearing capacity of the soil and secure deep excavations near existing buildings.
Bored pile foundations are created by drilling large holes in concrete columns that is connected using reinforced steel for maximum support. The load-carrying capacity is partly resisted by skin friction developed along the shaft as small diameter bored piles with a diameter up to 600 mm can be drilled using buckets and/or augers driven by percussion boring or rotary boring methods.
Additionally they can be used for stabilizing slopes and have been seen as an effective solution providing additional support during seismic activities. As such, knowing how best to use these type of piles will provide any project with great stability meaning those structures built on unstable land sites can now stand safely alongside other constructions!
Quality assurance
Quality assurance for bored pile foundations is an integral part of the construction process. It involves assessing and monitoring the quality of each individual pile in the system to ensure that they are built according to regulations, provide adequate strength and resist future movements or settlements.
Quality control measures such as direct visual inspection, reliability-based design methods (RBD), and regular checking/monitorment can be used to evaluate the performance of these piles and detect any defects or issues during construction.
RBD also provides valuable insights into how best to approach structural integrity assessments for piled structures. The Guide for Pile Foundation Design, Testing, and Practices aimed at improving existing practices can help inform choice of materials, piling methods, designs, features alignment etc., resulting in a robust foundation which meets engineering requirements before setting out on site work commences.
Process
• Bored pile installation usually starts with the construction of permanent or temporary casing. The outside of the casing should be steel or steel-reinforced, while the inside must also be durable enough to withstand drilling and pumping operations.
