Historical
Review
In Britain, there are numerous examples of timber
piling in bridge works and riverside settlements
constructed by the Romans
Timber, because of its lightness, durability and ease of cutting and handling, remained the
only material used for piling for along time
Reinforced concrete largely replaced timber for high-capacity piling for works on land
Steel has been used to an increasing extent for piling due to its ease of fabrication and
handling and its ability to withstand hard driving
3. Types of
foundation
Shallow foundation
It will be on the surface of the
ground level
Deep foundation
It will drive to lower soil layers such
as pile and pier

15. CAST-IN-PLACE CONCRETE PILES
Piles are built by making a hole in the ground and then filling it with
concrete. These piles may be divided to two: (a) cased (b) uncased. Both
types may have a pedestal at the bottom

Bulb Pile: They are special forms
of cast-in-place concrete piles. It
forms a large base (bulb) during the
driving process increases their
effectiveness in serving as an end
bearing pile.

SHELL TYPES CAST-IN-PLACE PILES
consist of a permanent light gauge steel tube in
diameters from 150 to 500 mm with wall thickness
up to 6 mm and are internally bottom driven by
drop hammer.
On reaching the bearing layer the hammer is
removed, any reinforcement inserted, and a high
slump concrete placed to produce the pile.

18. Advantages of Cast-In-Place
Concrete Piles
Disadvantages of Cast-In-
Place Concrete Piles
1) Relatively low cost.
2) Allow for inspection before pouring
concrete.
3) Easy of length variation.
4) Minimal ground vibrations during
installation.
1) The uncertainty of the shape and condition of
the constructed pile.
2) The cast components may be damaged during
driving.
3) Difficult to splice after concreting.
4) Steel casings (temporary or permanently) and
reinforcing cages may also be required.
5) Cast-in-place concrete pile lengths are limited
by the drilling equipment used.
18
19. Steel piles
are either pipe pile or rolled section steel H- section
piles.
Wide-flange and I-section steel beams can also be used as piles.
19
H-section piles are usually preferred because their web and flange
thickness are equal.
Pipe pile can be driven into the ground with their ends open or close.

SHOES FOR STEEL PILES
shoes or other strengthening
devices at the toe are needed for
tubular piles driven with open
ends in easy to moderately easy
driving conditions.
Where open-ended piles have to
be driven through moderately
resistant layers to obtain deeper
penetrations,
or where they have to be driven
into weak rock, the toes should be
strengthened by welding-on a
steel ring.
(a) Strengthening shoe of tubular steel pile by cruciform plates (b) Buckling and
tearing of welded-on external stiffening ring to tubular steel pile driven on to
sloping rock surface.

21. Advantages of Steel
Piles
Disadvantages of
Steel Piles
1) Easy to handle with respect to cutoff and
extension to the desired length.
2) Can stand high driving stresses.
3) Can penetrate hard layers such as dense
gravel and soft rock.
4) High load-carrying capacity.
1) Steel Piles subject to corrosion.
2) They are very expensive.
3) High level of noise during pile driving.
4) H-section may be damaged or deflected from
the vertical during driving through hard layers
or past major obstruction.
21
22. Composite
pile
combinations of bored piles with driven piles can be
used to overcome problems resulting from particular
site or ground conditions such as the problem of
timber piles above ground-water level
composite piles may be made of steel and concrete or timber
and concrete.
Steel and concrete piles consist of a lower portion of steel
and an upper portion of cast-in-place concrete
composite piles are not economical compared with those of
uniform section

23. NON-DISPLACEMENT
PILES
With non-displacement piles soil is removed
and the resulting hole filled with concrete or
sometimes a precast concrete pile is
dropped into the hole and grouted in.
This method of construction produces an irregular interface between the pile shaft and
surrounding soil which affords good skin frictional resistance under subsequent loading.

24. SMALL DIAMETER
BORED CAST-IN-
PLACE PILES
These tend to be 600mm or less in diameter and
are usually constructed by using a tripod rig. The
equipment consists of a tripod, a winch and a cable
operating a variety of tools

25. LARGE DIAMETER
BORED CAST-IN-
PLACE PILES
Large boreholes from 750mm up to 3m
diameter (with 7m under-reams) are possible
by using rotary drilling machinery. The
angering plant is usually crane or lorry
mounted.

26. PARTIALLY
PRE-FORMED
PILES
This type of pile is particularly suitable in conditions
where the ground is waterlogged, or where there is
movement of water in an upper layer of the soil which
could result in cement being leached from a cast-in-
place concrete pile

27. GROUT- OR
CONCRETE-
INTRUDED
PILES
The use of continuous flight augers is becoming a
much more popular method in pile construction.
These piles offer considerable environmental
advantages during construction
Their noise and vibration levels are low and there is
no need for temporary borehole wall casing or
bentonite slurry making it suitable for both clays
and granular soils
The only problem is that they are limited in depth to
the maximum length of the auger (about 25m)

28. SHEET PILES
Sheet piles are structural tools which are designed to resist
horizontal forces as they embedded in soils. They are also
used as retaining systems.
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.

29. CHOICE OF ILE
MATERIALS
Timber is cheap relative to concrete or steel. It is
light, easy to handle, and readily trimmed to the
required length. It is very durable below ground-water
level but is liable to decay above this level.
Concrete is adaptable for a wide range of pile types. It
can be used in precast form in driven piles, or as
insertion units in bored piles.
Steel is more expensive than timber or concrete but
this disadvantage may be outweighed by the ease of
handling steel piles, by their ability to withstand hard
driving, by their resilience and strength in bending,
and their capability to carry heavy loads

30. 1) The depth to a stratum capable of supporting a pile.
2) The availability of materials for piles.
3) The number of piles required.
4) The driving equipment.
5) The depth and kind of water if any, above the ground
which the piles will be driven.
6) Location and type of structure.
7) Types of structures adjacent to the site.
8) The size, weight of the structure.
9) The physical properties of the soil stratum on site.
10)The durability required.
11)The comparative in-place cost.

Factors Influencing
Choice Of Piles To Be
Used For Construction
31. PILE
HAMMERS
The available types include:
1) Drop.
2) Single-acting steam or compressed air
(60 blows per minute).
3) Double-acting steam or compressed
air (120 blows per minute).
4) Differential-acting steam or
compressed air ( Frequency usually
between single and double).
5) Diesel ( Can operate in freezing
weather, but may fail to operate in soft
soil).
6) Hydraulic.
7) Vibratory drivers ( most effective in
driving piles into granular soils, they
operate at very high frequencies).

equipment-hammers.html
31
32. Dropping weight
(Drop Hammer)
The dropping weight or drop
hammer is the most commonly used
method of insertion of displacement
piles.
Variants of the simple drop hammer are the single
acting and double acting hammers. These are
mechanically driven by steam, by compressed air
or hydraulically.

the diesel hammer.

Reference:http://www.powerquip.co.kr/products/hydraulic-pile-hammer_photo_M.html
This type of hammer is most suitable for driving piles
through non-cohesive granular soils where the major
resistance is from the end bearing.
34. Vibratory methods of pile driving:
Vibratory methods can prove to be very effective in driving piles through non cohesive
granular soils. 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.
Jacking methods of insertion:
Jacked piles are most commonly used in underpinning existing
structures. By excavating underneath a structure short lengths of
pile can be inserted and jacked into the ground using the underside
of the existing structure as a reaction.
