Function of the piles and its classification

Piles foundations are used to transfer the weight of the structure below the ground from the surface of the ground. Two main components of the foundation are pile and pile caps. Piles are long and slender structure that is buried deep in the ground to take the weight deep down in the ground. The piles are often touching the rock or solid ground, going beyond the shallow depth of the soil. The material of the pile and load transferring depends on the type of the soil.

Classification of the piles can be done on the load bearing characters and material used in the construction of the piles.

Point bearing piles are Bored piling contractors used to transfer the load of the structure to the deep part of the soil. The carrying capacity of these piles is derived from the resistance, which they get from the soil at the toe of the pile. The pile behaves like an ordinary pile and it is designed as such. The pile will never buckle under pressure even in weak soil.  The depth to which pile is inserted depends on the soil analyses, done by engineers before start of the construction.

Friction piles derive their carrying strength from the friction of the soil, which is in contact with the shaft of the pile. Cohesion piles transfer most of the weight of the structure by skin friction. The cohesion piles are inserted in groups close to each other. This process reduces the porosity and compressibility of the soil in and around. These piles area also called compaction piles. When the piles in inserted in the ground, the soil becomes molded and losses some of its strength, but it again regains that strength after some three to five months.

Classification of piles based on material used in construction –

Timber piles are used in areas where timber is widely available. The timber used for piling has to be of good quality and free from insects. The timber pile is place below the ground water level to protect it from decay and putrefaction.

Concrete piles can be under reamed pile foundation pre cast concrete and pre fabricated concrete piles. These are made in square, circular, triangular or rectangle shapes. These piles can be connected to produce the length required. The need for reinforcement is needed to enable the pile to withstand both driving and handing stress. Pre stressed piles are becoming more popular as they require less reinforcement.

Importance of soil testing before construction

All construction projects are made on the soil. The soil has to take the weight of the structures. The soil testing before construction is first step and important step for many reputed construction companies.

Soil testing is primarily done to test the bearing capacity of the soil. It also shows the physical and chemical composition of the coil.  These characteristics may vary from layer to layer of the same soil. The characteristics of the soil can change within small area due to weather, climate change and the management of the site can also change the bearing capacity of the soil.

The soil must be able to withstand the weight of the building otherwise the loss to property and life can occur. The soil investigations or analysis determines not only the bearing capacity of the soil, but it also rate of settlement of the soil. This rate determines the rate of the structure stabilization on the soil. The soil testing also determines the length and depth of the pillars put in the soil to lay the foundation of the building. The selection of suitable construction technique   and knowing the possible foundation problems all are based on the results of the soil testing. The water table level of the soil can be known only from the soil testing. The level of water table shows the likely problem to the foundation of the building and level of humidity within the foundation.  The choice of construction material may also be affected by the chemical and mineral component of the soil. If analysis of the soil reveals that it contains sulphur, then the sulphur resisting cement is used to protect the foundation of the buildings.

Understanding Geotechnical investigation of the soil helps to take better decisions leading to the success of the construction project. The height of the building and the use of materials are decided by the engineers on the basis of soil testing reports. The information then leads to strong and durable structures. The structure engineers can also decide whether there is need to go for soil stabilization or increase the depth of foundation for better stability of the building. The cost involved in the soil testing is just fraction of the contrition cost of the structure.

Whether the soil is Soil testing consultants sand, clay, gravel, silt or loom soil, the soil testing must be the first step construction of a building or any structure. Without soil testing, the building is exposed to the hidden dangers and all unknown weakness of the soil.

Foundations and types of pile foundations

Foundation is that part of the building that transfers the weight of the building to the ground. Every part of the building will have its own foundation and each column will have its own footing.

Before making foundations, the engineers have to study the capability of the soil to withstand the weight of the building or foundation. Two kinds of foundations are there, swallow and deep foundations.

Pile foundation piling agencies comes in the deep foundations. It is a long cylinder column of concrete that is pushed into the soil to build structure on it. Pile foundations are used when there is weak soil at the surface of the ground, where the construction has to take place, or when it is assumed that the surface cannot withstand the load of the building. The pile is then pushed to the ground, so that the weight is on the stronger soil or rock under the weak surface .Also pile foundation is often constructed in high rise buildings.

Type of pile foundations –

There are two kinds of pile foundations, end bearing pile and friction pile. The end bearing pile is inserted up to the strongest part of the soil and weight of the building is transferred to the soil by the end point of the pile, which is on a strong ground below the weak surface .In friction pile, the weight of the building is transferred to the soil through the height of the pile Here, the entire length of the cylindrical pile works to transfer the weight of the building to the soil. The amount of load, which a friction pile can transfer depends on the length of the pile .The weight is directly proportional to the length of the pile.

As pile foundations pile contractors are used to carry the entire weight of the building, they are made carefully by the engineers. An engineer also has to study the soil, to ensure that soil is capable of carrying the weight of the pile. The piles are inserted into the soil at some distance from each other to ensure that load of the buildings  is  distributed evenly in the soil over wide areas and not confined to narrow area .Engineers also group several piles together and cap them together with thick concrete cap .  The columns of the buildings are then built on these caps covering several piles.

Piles are often cast at the ground and then hampered into the ground with pile drivers. The pile driver is a machine that vertically inserts the pile into the ground blow by blow by hampering it with heavy load.
