Deep (Pile) Foundation

Bored piles: For these piles a hole is first bored in the ground, andthe pile is then usually formed in thehole. Both total stress and effective stress methods of analysis are used to estimate the side resistance for saturated clays. Here we consider only the total

Piles The principle behind piling is to transfer loads of a structure through strata of low bearing capacity to deeper soil or rock strata that has a higher bearing capacity.The loads can be transferred into underlying strata by either end bearing pile – (The strength of the pile is based on the bearing of the pile into a stiff strata), or friction base pile – (The strength of the pile is

Bored piles are installed by auguring into the ground forming a hole into which concrete can be poured, thereby casting the pile in position. This method of piling is well suited for work in cities and areas surrounding existing buildings as the vibration caused by installation is minimised.


A comparison of quality management for bored pile/drilled shaft

tom verticality of bored piles/drilled shafts filled with water or slurry, are ultrasonic methods. In ultrasonic methods, the travel time of a sound wave travelling from shaft top to a sensor located at the shaft bottom is measured. Ultrasonic equipment currently

Bored piles are also known as replacement piles as the soil is replaced by the pile. These piles provide foundation that supports structure with heavy vertical loads. The bored piles construction entails two main steps- the drilling phase and the construction phase.

using bored piles? 4. Large structural capacity 5. Construction with less noise and vibration. 6. Can be installed to great depths, more than 100m 7. Can overcome complicated geological stratum, eg. multiple layers of rock, and underground obstructions 1. 2.

Pile classifications Piles may be classified by their basic design function (end-bearing, friction or a combination) or by their method of construction (displacement (driven) or replacement (bored)). End-bearing piles develop most of their friction at the toe of the pile, bearing on a hard layer..

Bored Piles Bored piles are cylindrical concrete structures (with or without reinforcement) that are inserted into the ground using various methods. They transfer high structural loads into deeper load-bearing soil strata, form a supporting wall for an excavation pit or topographical change or seal off groundwater when tangenting or intersected.

Bored pile walls are used for basements, underpasses tunnels. The bored piling method creates either contiguous or interlocking secant pile walls. With many different piling methods available – from CFA piling to mini piling, it can be difficult to know how to differentiate them from one another.

Pile Foundation Classification By Installing Displacement Piles/ Driven Piles Displacement Piles which are driven are termed 'Displacement Piles' because their installation methods displace laterally the soils through which they are introduced Installation techniques Dropping weight The dropping weight or drop hammer is the most commonly used method of insertion of displacement piles

piles. Cast-in-place (or bored) piles do not cause any soil displacement, therefore, they are non-displace-ment piles. Piles may be loaded axially and/or transversely. The limit states necessary to be considered in the design of piles are the following (EN-1997-1,

This article presents an overview of non-destructive methods of examining piles, used for the control of their manufacturing, but, above all, their continuity and length evaluation. Also the fundamentals of measurement and result analysis have been included. 2.1.
