Piles types pdf
Also included in this category are piles formed by placing concrete as the driven piles are withdrawn. Also See: Types of Soil Settlement. These types of piles require a hole to be first bored into which the pile is then formed usually of reinforced concrete.
The shaft bore may be eased or uncased depending upon type of soil. Comparatively low initial cost, permanently submerged piles are resistant to decay, easy to handle, best suited for friction piles in granular material. Easy to splice, high capacity, small displacement, able to penetrate through light obstructions, best suited for end bearing on rock, reduce allowable capacity for corrosive locations or provide corrosion protection.
In general, a composite pile is made up of two or more sections of different materials or different pile types. The upper portion could be eased cast-in-place concrete combined with a lower portion of timber, steel H or concrete filled steel pipe pile. These piles have limited application and arc employed under special conditions.
It comes in the form of concrete and timber or concrete and steel. This type of pile is use by driving timber, concrete or steel piles into position by employing the pile-driving instrument. These types of piles employ only concrete piles. While in usage, the piles are drill and pack with concrete. It is possible to add reinforcements as per the requirements. This is the perfect amalgamation of driven and cast-in-situ piles. It employs casing or shell. One type of pile that is mostly use is Franki pile which is a part of driven and cast-in-situ piles.
Great option while working over water as it can be highly effective in wharf structures and piles in jetties. Pile foundations are in high demand when it comes to transferring the loads from superstructures from weak foundation to a more strong and less compressible stiffer soil. This way it withstands all the horizontal loads and enhances the effectiveness of the foundation. Pile foundations can be extremely effective when there is a weak soil layer at the surface.
The layer will not be able to support the weight of the building. When loads of the buildings pass the pile foundations it is shift to a stronger pile of rock that is just underneath the weak layer. It has been observe that the depth of the footings should have a minimum depth of 12 inches below the past undisturb soil.
As far as the footings are concern, they should be a minimum of 12 inches underneath the frost line or must be protect from frost. The width of the footings needs to be at least 12 inches. If you are near bedrock or need reinforcement with steel it is important to dig deep foundations.
Commence any type of foundation by digging footings that are a minimum of 2 feet wide and as deep as the frost line. There will be certain foundations that might need an additional width, some of a maximum 6 feet wide. We have provide a comprehensive overview of pile foundation in this write-up. After reading this write-up, we hope you will be able to understand the subject matter in hand more appropriately.
Sheet pile walls are employed as bulkheads in piers, docks and harbours, and in sea walls, break waters, and other shore protection works. A bulkhead provides a vertical They are widely used wall so that ships may tie-up along side.
A bulkhead may also serve as a pier. In contrast to the retaining walls, which are rigid bulky structures, bulkheads are flexible, generally composed of a single row of partially embedded sheet piles with major portion of the lateral support furnished externally. The upper and lower edges of bulkhead are practically fixed on account of the anchorage at the top and the passive resistance of the soil adjoining the lowest part of the bulkhead.
The use of the anchor member tends to reduce the lateral deflection, the bending moment, and the depth of penetration of the pile. According to the mode of establishing the retaining system, bulkhead may be classified as. A fill bulkhead is the one which is constructed in open water and then backfilled. If the bulk- head is constructed in natural ground by driving and then the earth removed from its face by dredging, it called dredged bulkhead.
This is an important classification, according to which a bulkhead may be cantilever type or may be anchored.

U sheet piles have interlocks on the neutral axis and symmetrically form a wall with a narrow section resulting in high drivability and reusability.
Furthermore, the large width ensures fast installation performance. The primary elements universal beams act as retaining elements against the earth and water pressures and may act as bearing piles for vertical loads.
The secondary elements U sheet piles only fill the gap between the primary elements and transmit the loads resulting from earth and water pressures to the primary elements.
