You can also find a student's guide for Pile Foundation Design. Sir i would like to download that ppt from which it would help for a related seminar of mine. Pile foundations are principally used to transfer the loads from super structure, through weak compressible strata or water on to stronger, more compact, less compressible and stiffer soil or rock. In pile foundation, piles of different material in different manner are used. This guide has extracted the main points and puts together the whole process of pile foundation design in a student-friendly manner. Pile Foundation ppt Submitted by Vivek Mishra www. They can easily be extracted 2.
Easily damaged during hard driving and inconvenient to splice. Friction Piles When no layer of rock is present depth at a site, point bearing piles become very long and uneconomical. Steel piles: Steel can be used for both temporary and permanent works.

A different amount for each type of soil A different amount for an individual soil … When placed under different Stress conditions.
Pile installation will always cause change of adjacent soil properties, sometimes good, sometimes bad. It can be used in precast form in driven piles, or as insertion units in bored piles. Classification based on load transmission: End bearing piles Point bearing These transmit most of their loads to the load bearing layer which can be dense sand or rock. I've gone through the ppt of the pile foundation of your's. This stream of engineering is getting noticed and popular nowadays due to public awareness and resource conservation campaigns.
The vibration of the pile excites the soil grains adjacent to the pile making the soil almost free flowing thus significantly reducing friction along the pile shaft. Wide-flange and I-section steel beams can also be used as piles. By Nature Uncontrolled By People Controlled Deep Foundations : Deep Foundations Piles Pile foundations are the part of a structure used to carry and transfer the load of the structure to the bearing ground located at some depth below ground surface. This branch basically deals with construction methodologies and building materials that can enhance the function and performance of the structures. Pile Installation Methods In pile foundations, Installation process and methods of installation are equally important as the design process. You can of civil presentations on structural engineering here.
Fairly easy to drive, minimal soil displacement, good penetration through hard materials with shoe. It can be considered as sub branch of environmental engineering as these two branches share similar functions. There are two methods for the installation of piles. Timber pile cannot withstand hard driving stress. Pipe pile can be driven into the ground with their ends open or close.
The seminar report on the topic Pile foundation for civil engineering students discusses the process of pile foundation design, introductions and problems definition. The branch basically deals with analysis and design of structures. Classification of Pile foundations: The pile foundations are classified based on load carrying characteristic of piles, material of pile construction and type of soil. During the design of piles, the method and equipment should be carefully selected in order to avoid the damages to the pile. These drawbacks can be overcome by employing jointed piles Typical locking pin joint for precast concrete pile. Pile driving using hammer Vibration: The amplitude of vibration used here should be sufficient to break the skin friction on sides of pile.
Underrreaming tool open position Negative skin friction When a fill or load is placed on compressible soil deposit, consolidation takes place. Pile foundations are required for the transmission of structure loads through deep water to a firm stratum. You can various Building Technology ppts and download it. The load is usually transmitted by means of a hydraulic jack placed between the top of the pile and a beam supported by two or more reaction piles. It also includes important activities such as marking the center line, boring, lowering of reinforcement, concreting, excavation, chipping of pile cap etc. The analysis of piles subjected to lateral and moment loading is more complex than simple vertical loading because of the soil-structure interaction. This approach gives more realistic estimate of pile capacity.
Depending upon type of soil, pile material and load transmitting characteristic piles are classified accordingly. Construction Methods and Management, 7th edition, S. Over the years, this construction material has been enhanced and developed to fit to the usage and requirements at site. The Screw auger tube b Cleaned-off section of an excavated Screw pile. Sheet piles are made of different materials as wood, concrete, steel or aluminum which play an important role in their applications Sheet piles are widely used for several purposes such as: 1 Large and waterfront structures 2 Erosion protection 3 Stabilizing ground slopes 4 Shoring walls of trenches and other excavations, and cofferdams.
End-bearing pile Friction piles : These transmit their load through the layers through which the pass which is mostly through the surface friction skin friction with the surrounding soils. Continued Piles are relatively long , slender members that transmit foundation loads through soil strata of low bearing capacity to deeper soil or rock strata of high bearing capacity. Basic Types of Sheet Pile Walls and Their Application in the Construction Industry, Leila Eskandari, Department of civil engineering, University of Hormozgan, Bandar abbas, Iran. Thus, they are end bearing piles and act as columns or piers. Se você continuar a utilizar o site, você aceita o uso de cookies.
