Description of different types of piles
1. Bearing pile:
A bearing pile is a pile that transfers the load of a structure through soft soil or water to a solid level with the required bearing capacity. A pile is placed directly on the hard surface of the soil interior. It supports the superstructure as a pillar and breaks the load to a safe loading level. Bearing piles can be of wood or concrete.
2. Friction pile:
In places where the soil is weak or soft to a great depth, the friction force generated between the soil surrounding the inserted pile and the pile surface carries the load.(steel pile) That is, the skin transfers the load through friction. This type of pile is also called friction pile or floating pile.
Fractional piles are used where the bearing capacity of the soil does not increase with increasing depth or the rate of increase in bearing capacity is less than the increase in depth.
3. Sheet pile:
(hammered into the ground)This pile acts as a barrier to the horizontal movement of the soil. It is completely different from bearing and friction piles. Because the sheet pile acts as a retaining wall. It does not act as steep support. Where horizontal displacement of soil occurs when load is applied to the soil, sheet piles are used to prevent all soil displacement. Or sheet piles are used to enclose the soil in a specific area for a foundation to prevent it from leaking flowing water or water.
4. Anchor pile:(bored piles)
Anchor piles are used to resist the horizontal pull or other horizontal pull of the sheet piling wall.
5. Batter pile :(pile foundations)
A batter pile is a pile placed diagonally to prevent a horizontal or diagonal ball.
6. Feder Pile:(shallow foundation)
Feder piles are piles used to protect concrete decks or any other water-side structure from ship or barge or any floating object. These piles are usually made of wood.
Compaction pile:
Piles used to increase the bearing capacity of granular soil are called compaction piles.
6. Timber pile:(driven into the ground)
The use of timber piles is convenient for constructing light structures on wet and compacted soils. It also costs less. The load is spread by the frictional force between the soil and the pile surface. Timber piles are more commonly used as friction piles. Wooden piles are made from trees like shawl, teak, cedar, acacia, khayer etc. Wood piles are used for coastal construction work as they are not damaged by salinity. Wooden piles are square or round. Round woods range in diameter from 30 cm to 50 cm.(deep foundation) The lower part of the pile is narrow jar size ranging from 15 cm to 16 cm. The length of a wooden pile should generally not exceed 20 inches above the size of the pile. At the bottom end of the C.I. Who is using Su.
Advantages of Timber Pile:(driving piles)
1. A. Piles are cheaper and cost less.
2. It can be easily lengthened with a pair.
3. Quick placement inventory. The result is less waste of time.
4. There is no need for heavy animals and skilled technicians for laying these piles.
Disadvantages of timber piles(piles are driven)
1. These piles are damaged by insects and salt water.
2. It is not possible to place this pile in the case of letters in the case of Indian soil.
3. For the stability of the pile, the pile has to be cut below the permanent level of water. As a result, the water level in the subsoil is much deeper and it costs more to excavate the pile cap.
4. As the length of this pile is limited, there is no need to use long piles. Because the joint space of the pile is very weak.(piles are driven)
5. The bearing capacity of this pile is less.
. It is very difficult to place in a hard layer of soil.
Pre-cast or pre-cast concrete piles(support for structures)
1. In the case of permanent structures, pre-cast concrete piles are used where additional bearing is required. These piles are cast and cured in a convenient place away from the workplace. Later it is brought for work placement.(driving piles) These piles are round, rectangular, octagonal in shape. The diameter of this pile varies from 35 cm to 65 cm and from 4.5 m to 30 m.
Advantages of pre-cast piles:(deep foundation)
1. High quality piles are made by skilled craftsmen and any defect can be easily repaired.
2. The pile rods should be placed in place.(bored piles)
3. Concrete acquires full strength as it is used after mass curing and it is convenient for installation.
4. This pile is also placed with water.(pile foundations)
5. It is convenient to place this pile in soft and wet soil.
. The cost is lower as many piles are made at the same time.
. After loading the pile, the load is applied.
Disadvantages of pre-cast piles-steel pile
1. It is very heavy and difficult to transfer.
2. If care is not taken while transferring and placing the pile, the pile may break and win.
3. Heavy machinery is required for placing piles.
4. The pile cannot be lengthened for the convenience of transfer work.
5. Increasing the length with a pair costs more and takes a lot of effort.
. Injuries during the installation of the pile weaken the pile somewhat.
9. If the required number of piles is not available in a short time, the installation of piles is delayed.
