What are the 2 different piles applications can end up in?
Piles can be categorized in two main types: load bearing piles and sheet piles. There are numerous types of load bearing piles.
What is pile cap made of?
They are formed by long, slender, columnar elements typically made from steel or reinforced concrete, or sometimes timber. A foundation is described as ‘piled’ when its depth is more than three times its breadth.
How do I know my pile cap size?
Here is how to assume the thickness of the pile cap:
- If diameter of pile < 550mm: thickness = 2 x diameter of pile.
- If diameter of pile > 550mm: thickness = 1/3[(8 x diameter of pile)-600]
What is a steel pile?
Steel sheet piles are long structural sections with a vertical interlocking system that create a continuous wall. The walls are often used to retain either soil or water. The pile transfers pressure from the high side of the wall to the soil in front of the wall.
How many types of piles are there in construction?
There are three types of pile foundations according to their construction methods which are driven piles, cast-in-situ piles, and driven and cast-in-situ piles.
What is the difference between a pile cap and a pier cap?
Drilled Piers vs Piles: Comparison at a Glance Piers are similar in size and shape. Piles are often used when the soil lacks firm strata, such as bedrock. Piles are usually meant for supporting greater loads, such as highway bridges. Piers are meant for smaller applications, such as sheds and small living units.
How do you install piling caps?
How Do I Install Piling Caps?
- Measure about ¾” up from the bottom of the cap and drill 4 small holes around the perimeter.
- Place the cap on the piling and make sure it’s sitting level.
- Run the nails or screws through the holes and into the piling just until the head of the nail or screw touches the cap, then stop.
How deep should a pile cap be?
consider 150mm offset from the pile and space between piles as 2.5 times pile diameter. Effective depth, d = 1000-50-20/2 = 940 mm > 750mm; (2.5×600/2) Ok. The critical section of the pile shall be considered as 20% of the diameter of the pile inside of the face of the pile.
What should be the depth of pile cap?
Table: Pile cap depth for different pile diameters
| Pile Diameters (mm) | Depth of Pile Cap (mm) |
|---|---|
| 500 | 1100 |
| 550 | 1200 |
| 600 | 1400 |
| 750 | 1800 |
What is CFA piles?
Continuous flight auger (CFA) piles are drilled and concreted in one continuous operation enabling much faster installation time than for bored piles. Reinforcement is placed into the wet concrete after casting, enabling the pile to resist the full range of structural loading.
What do you need to know about a pile cap?
A pile cap is a mass concrete structure contains more piles embeds in it. A group of pill drives into clay, soft, and loose soils to provide a strong, stable and suitable foundation. The pile designs considering the punching shea around the heads of the piles and column base.
What are the different types of steel piles?
The types of steel piles commonly used are: 1 H-Piles 2 Pipe-piles 3 Screw piles 4 Disc piles More
Are there pile caps on reinforced concrete piles?
The first studies of great relevance, regarding the design of pile caps, are from Blévot & Frémy1 however, most of the researches on this area studied pile caps on reinforced concrete piles, leaving a vast field to be explored about pile caps on steel piles.
How big is a steel pipe for piling?
In this case also, after driving, the hollow space inside the pipe is normally, filled with concrete. The diameter of the pipes used for piling varies from 25 cm to 120 cm and their shell thickness varies from 8 mm to 12 mm The use of this type of pile for depths of 30 in or more is quite common.
