What Is Shoring In Construction?
Shoring in construction is a process of providing temporary structural support to existing structures, such as buildings and bridges.
It involves the installation of props and other supports (such as steel beams) in order to provide additional strength, stability or protection from damage or collapse during the course of construction work.
Other forms of shoring include underpinning, bracing, shielding and counteracting soil erosion. Shoring is most commonly used when carrying out excavation work, particularly when digging significant depths below ground level.
Why Is Shoring Important?
Shoring is an important part of construction that supports unstable walls, floors, and ceilings. It stabilizes structures and helps to prevent them from collapsing due to development or even natural disasters such as earthquakes.
Additionally, it reinforces the structure and prevents settling during changing weather conditions or after a natural disaster.
Shoring also allows for proper installation of roofing materials, windows, doors, and other fixtures needed to complete the construction.
Furthermore, shoring protects workers close by by protecting against potential falling bricks or other debris while onsite.
What Are The Types Of Shoring In Construction?
Shoring in construction is a technique used to support or reinforce buildings, walls, trenches, or other structures during excavation and construction.
There are four main types of shoring systems which include deadman anchors, soldier pile wall systems, sheet piling wall systems and strutting wall systems.
- Deadman anchors are used to provide lateral support for trench walls by making use of heavy timber beams or steel poles that have been buried in the ground at an angle away from the face of the trench and are held firmly in place with cables or chains.
- Soldier pile walls involve interlocking wooden piles spaced at intervals along the length of a trench while sheet piling utilizes long panels made out of metal, wood or plastic that can be driven into the ground up to significant depths.
- Strutting involves using steel struts to shore up deep excavations that require additional stability as a result of their depth.
When Is Secant Pile Shoring Required?
Secant pile shoring is a complex construction technique used in civil engineering foundations, retaining walls and bridge abutments.
It involves driving steel beams into the ground to form a perimeter wall around an excavation pit, then pouring concrete between them to stabilise the soil and form a permanent watertight boundary.
Secant piles are usually required for deep foundation pits or basement excavations in areas of unstable or wet soils, where other forms of retaining wall may not be adequate.
This technique can also be used when there is limited space available and traditional sheet piling methods would be too disruptive or costly.
It is typically more expensive than traditional sheet piling but provides improved stability and watertightness.
What Is The Most Common Type Of Shoring?
The most common type of shoring is called ‘post shores’, which involve pre-fabricated posts being installed into the ground and then being linked together with cross-bracing or other stabilizing components.
This type of shoring is used in a variety of applications, such as construction projects, repair works and large commercial developments.
Post shores can be made from steel or timber depending on the specific requirements needed for each project.
The advantages that post shores have over other types of shoring include their cost-effectiveness, convenience and durability.
