[′bad·ər ‚pīl] (civil engineering) A pile driven at an inclination to the vertical to provide resistance to horizontal forces. Also known as brace pile; spur pile.

Relative density Test can be performed in laboratory and minimum and maximum density can be obtained. Generally sand is compacted to achieve 70–80% relative density. After compaction, field density can be found by performing sand replacement test on field.

5 Types of Pile Foundation

• Bored Piling. Bored piles are installed by auguring into the ground forming a hole into which concrete can be poured, thereby casting the pile in position.
• Driven Piling. Driven piles are driven or hammered into the ground with the use of vibration.
• Screw Piling.
• Mini Piling.
• Sheet Piling.

Tension piles resist uplift forces through the action of friction along their length, by under-reaming (that is enlarging the end of the pile), by the action of helical bearing plates welded to the pile shaft, or by bonding the pile into rock.

Sheet piles are designed to interlock with each other. They are installed in sequence along the planned excavation perimeter. When arranged together, they form a wall for permanent or temporary earth support, along with anchors to provide extra lateral support. If the soil is too dense or hard, impact hammers are used.

Combined sheet piling wall beam and pipe king piles are able to go deeper into dense soils than sheet piling sections of a contiguous wall — approximately 6.5 feet (2 meters) compared to 1.5 feet (0.5 meters).

Sheet pile wall types

• Wooden sheet piles. Wooden sheet piles.
• Steel sheet piles. Steel sheet pile is a rolled steel section consisting of a plate called the web with integral interlocks on each edge.
• Concrete. Precast concrete sheet piles.
• Light-gauge aluminium sheet piles.
• Vinyl sheet piles.
• Fiberglass sheet piles.

STEELANT® is highly resistant to water and offers a unique and durable bond.

Earlier study on composite sheet piles includes recycled HDPE in tongue-and-groove profile reinforced with chopped glass fibres as potential material [3]. As opposed to the other type of composite piles which carry vertical axial load, FRP sheet piles in general are used for a wall that resists horizontal loads.

The piles may be constructed so that they virtually touch each other (contiguous). The gaps between the piles can be grouted to form a watertight retaining wall. Alternatively (secant piles) every other pile may be constructed, with their centres less than two diameters apart.

The cost range of approximately $1.2 million to $4.1 million to install a steel sheet piling barrier on the MDSL site is higher than the cost estimates for a soil- bentonite slurry wall, but less costly than the cement- bentonite option.

Steel pipe piles had the highest unit costs, ranging from $213 per meter for the 81.3-cm pile to $819 for the 154.9-cm pile. Unit costs for the PPC piles were lower, ranging from $72 to $197 per meter for the 30-cm PPC piles and $95 to $262 per meter for the 41-cm piles.

Basically, steel piles are a big screw, made of galvanized steel with a helical flange that not only helps to insert the pile, but also helps secure it into the ground. By using a mini-excavator with special attachments, a drill can enter the ground while measuring the load bearing capacity of the soil.

Trench sheets and light piling are used to support the ground at the sides of trenches and excavations. Generation provide a full range of temporary and permanent trench sheeting to support your requirements.

A Trench box, also known as Trench shield, is a structure that is made of either steel or aluminum which is used as a form of protection for utility workers while performing their construction responsibilities or task within a trench.

Caissons are watertight structures made up of wood, steel or reinforced concrete built above the ground level and then sunken into the ground. Caisson is putting a box into underwater and pouring it with concrete. Pile is a column of material driven by a piledriver.

Advantages of Pile Foundation: The piles can be pre-prepared according to its length. The precast process reduces completion time. It can be installed over a very large area & very long lengths. We can use piles in a place where drilling is not required.

Prefabricated piles are driven into the ground using a pile driver. Driving piles, as opposed to drilling shafts, is advantageous because the soil displaced by driving the piles compresses the surrounding soil, causing greater friction against the sides of the piles, thus increasing their load-bearing capacity.

Check if it’s piles

1. bright red blood after you poo.
2. an itchy anus.
3. feeling like you still need to poo after going to the toilet.
4. slimy mucus in your underwear or on toilet paper after wiping your bottom.
5. lumps around your anus.
6. pain around your anus.
