Introduction of Helical Piles

What Is a Helical Pile?

How Do Helical Piles Work?

• Helical piles, which can be seen as a form of residential helical piles, are installed by rotating them into the soil, just like a corkscrew is twisted into a bottle of wine. One might wonder, helical pile or concrete: which is better? The answer often depends on the specific requirements and soil conditions.
• The shaft of each pile disappears below the face, so fresh extension parts are connected with bolted couplers and screwed into the soil as well evenly performing in a single pile.
• In numerous cases, the steel pile itself is enough to meet the cargo conditions of the design.
• The more robust deep foundation systems, concrete (grout), can be incorporated.
• The concrete is continuously poured down the sides of the column, following the relegation plate and boxing the steel shaft.
• This fashion produces a collaborated pillar that will repel the most extreme compressive, uplift, and lateral forces.

What Are Helical Piles Made of?

Benefits of Helical Piles

• Easy to install
• Cost-effective
• Minimum impact
• Functional in poor soil
• High loading capacity

1. Easy Installation

• Helical piles are not required specialized machinery for installation.
• The helical pile can be drilled about 10 feet. Therefore it is a fast process.

2. Cost-Effective

• Helical piles are very more affordable to manufacture, transport, and install.
• Helical piles don't require costly concrete piles.
• A Helical pile can be reused for some form of works of the foundation for other sites.

3. Minimum Impact

• Helical piles should not require more space, human resources, or machinery.
• Therefore they produce a lesser impact on a construction site and the environment.
• Helical piles do not require soil removal; therefore, the wastage of soil is also minimized.

4.  Functional in Poor Condition

• Helical piles, especially when considering helical piles in rocky soil, are designed in such a manner that it allows them to contraction the existing soil and apply pressure to it.
• Where soil quality is in poor condition, helical piles are more suitable.

Types of Helical Pile Design

• Solid square shaft
• Round shaft pipe
• Square and round shaft combo piles
• Grouted square shaft

1. Solid Square Shaft

• The square shaft is solid, and it’s able of large axial compressive loads.
• The solid shaft is continuous at each extension. It will be carrying the load down through to the end of the pile.
• Square shaft extensions can also be used in a variety of tension operations.
• The solid square shaft should be various size such as1.5”, 1.75”, 2”, 2.25”.

2. Round Shaft Pipe

• The round shaft pipe helical pile, which can be considered under screw pile foundation details, gives a broader diameter than square shaft piles. This design often influences the overall screw pile cost.
• The wider cross-section provides better structural capacity like as large moments, lateral loading, or buckling.
• The round shaft pipe should be sizes2.875”, 3.5”, 4.5”, 6”, 8”, 10″.

3. Square and Round Combo Shaft Piles

• The combo pile has square shaft piles and round shaft piles.
• These types of helical piles are used in compression applications. The layers of hard soil are located deep under a softer surface soil.
• Square and round combo piles are chosen for high water tables, restricted grout sites. The more economical choice than a grouted pile
• The square and round shaft combo piles should be sizes5”/2.875”, 1.75”/3.5”, 2.25”/4.5″

4. Grouted Square Shaft

• All square shaft piles can be fitted with accessories to add a grouted covering.
• This covering is 5” to 8” in diameter and can be cased in PVC or steel pipe, or just grout.
• The grout also creates skin disunion with the soil that can help the contraction and pressure capacity of the pile.
• The larger cross-section should be lateral capacities, bending moment, and buckling resistance strength.

Helical Pile Foundation Cost

1. Soil Conditions

• Soil conditions are proper when a helical pile is installed.
• Soil is softened, or the natural water table is high, and then invests more cost in it.

2. Types of Helical Piles

• Foundation cost also depends on the types of helical piles.
• There are two main types of helical piles, such as round shafts and one square shaft.
• Depth of installation
• Helical piles must be dug deeper.
• More materials and more time are needed to dig deeper.
• It’s ultimately cost increases in installation.

3. The Number of Helical Piles Required.

• More number of helical piles means more cost.
• The requirements of piles are determined by loading, structure type, and supports.
• The above things are considered in the final estimated cost.

Helical Piers for Pools

Ideal Helical Piles

1. Done in a Day

• The residential house foundation, Ideal helical piles can be installed in a day, allowing to continue with the construction of the slab straight down.
• This is easily achieved with an off-shelf helical pier system.

2. Measure Process

• Every Ideal helical pier is installed to the designed depth and capacity, with readings logged, proof, and reviewed by engineers before subscribing off foundations.

3. Deep Savings

• The concrete piers are changed to helical piers. The deeper foundations have, the greater the savings will achieve over concrete piers.
• Even more significant savings for problem sites,
• Savings start from 1.5m deep.
