Castinplace concrete piles eliminate the need for pile driving machinery which can cause dangerous vibrations and precipitate landslides and which is sometimes too costly for use on small jobs. The first method of castinplace piles is with steel cores. The method was developed by the Washington State Highway department because of hairline cracks that were appearing in the area in which the ...
To construct the pile foundation, special machinery is employed to drill (punch) deep holes in the subgrade and the reinforcement framework is placed therein, followed by pouring concrete underwater, with water head pressure or a combination of water head pressure and mud slurry used to .

Pile foundations are quite effective, especially in weaker soils, for transferring the structural loads into the underlying ground. The current procedures for pile design are generally semiempirical, based on elastic theories and pile load test data. Finite element method (FEM) is a valuable tool in modeling loaddeformation characteristics of ...
A pile foundation is a long slender foundation member made of timber, structural steel or concrete which might be castinsitu or driven at place. It acts as a structural member to transfer the load of the structure to a required depth in deep foundation to carries the load .
· Bored pile, also called drilled shaft, is a type of reinforcedconcrete foundation that supports structures with heavy vertical bored pile is a castinplace concrete pile, meaning the pile is cast on the construction differs from other concrete pile foundations, like spun pile and reinforced concrete square pile foundations, which use precast concrete piles.
The best example of pile foundation is '' Ghat '' at Kashi – Varanasi raised on the bank of Ganges. A pile is an element of construction composed of timber, concrete, or steel or some combination of these materials. A pile is either driven into the soil or formed on site by excavating a .
· Pile foundation is the oldest method of providing a safe, sound and a dependable foundation. A pile is an element of construction consisting of timber, concrete, or steel or combination of these. It is either driven into the soil or formed onsite by excavating a hole and grouting bore with concrete.
The installation process and methods of pile foundations are equally important factors as of the design process. Pile foundation installation methods are by pile hammer and boring by mechanical auger. To avoid damages to the piles, during design, installation Methods and installation equipment should be carefully selected.

Concrete Piles. Precast Concrete Pile. This type of piles is cast in pile bed in the horizontal form if they are rectangular in shape. Usually, circular piles are cast in vertical forms. Precast piles are usually reinforced with steel to prevent breakage during its mobilization from casting bed to the location of the foundation. After the piles are cast, curing has to be performed as per ...
Transmission Tower Reinforced Concrete Pile Cap Foundation The purpose of a transmission line tower is to support conductors carrying electrical power and one or two ground wires at suitable distances above the ground level and from each other. The transmission line towers cost about 35 to 45 per cent of the total cost of the transmission line. A transmission tower is commonly a space truss ...
Precast concrete piles are used in the construction of foundations for a wide range of different structures in the civil engineering and building sectors. As precast piles are suitable for all applications and ground conditions, they provide a very costeffective piling solution. They are quick to install without producing spoil or arising material in the process, providing a further saving on ...

The tremie method of concrete placement is used for the concrete pouring of the pile foundation. This method uses a vertical pipe, through which concrete is placed by gravity feed blow water level. The lower end of the tremie pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the under ground water.

As pile foundations carry a lot of load, they must be installed with utmost care. The selection of suitable equipment and the process employed for concrete pouring may vary based on the pile size and location of the structure. If the pile borehole is dry, one may use any suitable means to pour concrete.
5 Pile Foundations General 51 Introduction Pile foundations are used when the underlying soils are incapable of resisting the loads from the structure. The piling is placed in the ground through poor quality materials to bear on competent soils. The piles are either driven into the ground or holes and filled with reinforced concrete. The piles transfer the load by bearing on competent ...
Dec 03, 2017· Pile foundation act as a steady support for structures making use of the skin friction with the ground as well as the increased bearing capacity of the soil at greater depths. We would not deal here the design of the pile foundation but would only talk about its construction procedure at site. Read More
The concrete shall be placed by tremie tube method, the tremie size will not be less than 150 mm. The tremie pipe is made up of sections with sufficient length to reach the toe of the pile and the joints provided with seals. The tremie pipe will be inserted at the center of the pile to reach upto the toe.
