Helical Piles
- Helical piles, also known as screw piles, screw piers, or helical anchors, are remarkable engineering solutions that play a crucial role in supporting structures. Let’s explore the details:
What Do Helical Piles Do?
o The primary purpose of helical piles is to provide foundational support for various types and sizes of structures.
o Like traditional pile foundations, helical piles are embedded deep underground to distribute the immense weight borne by the structure.
o Multiple helical piles create a stable platform on which buildings, bridges, and other large structures can rest. Composition of Helical Piles:o Shaft Material: Most helical piles consist of round hollow shafts or square solid shafts made of steel.
o Helical Bearing Plates: These steel shafts have one or more screw threads (helical bearing plates) welded onto them. These plates provide downward force as the pile is screwed into the soil.
​
How Do Helical Piles Work?
o Installation: Helical piles are twisted into the soil, much like a corkscrew into a wine bottle. As each pile’s shaft disappears below the surface, additional extension segments are bolted together and screwed into the soil.
o Load-Bearing Capacity: In many cases, the steel pile itself meets the project’s load requirements.
Advantages of Helical Piles:
o Restricted Spaces: Helical piles excel in areas with limited height and access.
o No Spoil Material: Unlike some other foundation methods, helical piles do not generate spoil material that needs disposal.
Micro Piles
Micropiles, also known as Mini piles, are indeed fascinating engineering solutions! Let’s delve into their details:
​
Definition and Purpose:
-
Micropiles are slender, high-capacity piles used in foundation construction.
-
They serve various purposes, including supporting structures, transferring loads, and stabilizing soil.
-
These piles are particularly useful in restricted spaces or areas with limited headroom.
Characteristics:
-
Diameter: Micropiles typically have diameters ranging from 4 to 10 inches.
Load Capacity: Their load-bearing capacity can vary significantly, spanning from 5 to 125 tons or even higher.
Construction Techniques:
-
Drilling Equipment: Micropiles are created using specialized drilling equipment. The compact size of this equipment is crucial for working in tight spaces.
-
Grouting Techniques: Grout (a cementitious material) is injected into the micropile to enhance its load-bearing capacity and improve soil stability.
Applications:
-
Foundation Support: Micropiles are commonly used to support structures such as buildings, bridges, and retaining walls.
-
Slope Stabilization: They help stabilize slopes and prevent landslides.
-
Underpinning: Micropiles can be employed for underpinning existing structures.
Down the Hole Piles (DTH)
-
Down-the-hole (DTH) piles, also known as drilled DTH piles, are an intriguing foundation solution. Let’s explore their characteristics and applications.
​
Definition and Purpose:
-
DTH Piles: These piles use a combination of percussive and drilling mechanisms.
-
Hammer Action: The hammer directly impacts the rock to advance a hole into it and simultaneously drives the pile into that hole.
-
Air-Lift Exhaust: Drill cuttings and debris at the rock face are removed by an air-lift exhaust up the inside of the pile1
Applications:
-
Boring Through Boulders and Obstructions:
-
Temporary or Permanent Casing: It can install either temporary or permanent casing.
-
Pre-Drilling for CFA Projects: It’s also used for pre-drilling in continuous flight auger (CFA) projects.
Advantages:
-
Restricted Height and Access
-
No Spoil Material
Driven Piles
Driven piles, also known as displacement piles, are a commonly used form of building foundation. Let’s explore their characteristics and applications.
​
Definition and Purpose:
-
Driven piles are inserted into the ground using impact or vibration hammers.
-
Their primary purpose is to provide support for structures by transferring the load to layers of soil or rock with sufficient bearing capacity and suitable settlement characteristics.
Applications:
-
Structural Support: Driven piles provide foundational support for buildings and other structures.
-
Earth Retention: They offer lateral support for retaining walls.
Advantages:
-
Restricted Height and Access: Driven piles excel in areas with limited height and access.
-
Cost-Effective: Compared to cast-in-situ bored piles, they are more cost-effective.
