Screw piles for underpinning are a specialized foundation solution used to stabilize and support existing structures, especially in cases where the foundation has become unstable or needs reinforcement. Underpinning with screw piles is a popular method because it offers various advantages over traditional underpinning methods, such as minimal disturbance to the site, faster installation, and cost-effectiveness. Here are some key points to know about screw piles for underpinning:
What are screw piles?
Screw piles, also known as helical piles or screw anchors, are deep foundation elements with a helical screw-shaped plate welded to a central shaft. They are usually made of steel and designed to be screwed into the ground to reach load-bearing strata. The helical design allows the piles to generate resistance and stability in a variety of soil conditions.
Applications of screw piles for underpinning: Screw piles are commonly used for underpinning to stabilize structures that are experiencing foundation settlement, subsidence, or structural issues due to unstable soil conditions. They can be used for residential, commercial, and industrial buildings, as well as for infrastructure like bridges and other civil engineering projects.
Advantages:
Minimal excavation and disruption: Screw piles are installed directly into the ground, minimizing the need for extensive excavation and reducing disruption to the site and surrounding areas.
Fast installation: Screw piles can be installed quickly, making them a time-efficient underpinning solution compared to traditional methods.
Immediate loading: Once installed, screw piles can immediately bear the load of the structure, eliminating the need for waiting periods.
Versatility: Screw piles can be used in various soil conditions, including soft soils, clay, sand, and even in areas with a high water table.
Cost-effectiveness: The overall cost of underpinning with screw piles can be lower than other methods due to reduced labor and equipment requirements.
Installation process:
A specialized hydraulic motor, often mounted on an excavator, rotates the screw pile into the ground.
The depth and number of screw piles required are determined by factors such as the structure's weight, soil conditions, and the extent of foundation issues.
The screw piles are advanced into the ground until they reach stable load-bearing strata, providing a solid foundation for the structure.
Engineering considerations:
Underpinning with screw piles requires careful engineering analysis and design to ensure that the piles can support the structure adequately.
The size, type, and spacing of the screw piles are determined based on the building's weight and specific site conditions.
Professional installation:
Screw pile underpinning should always be performed by experienced and qualified professionals, as improper installation can lead to further issues with the structure.
