Hi friend’s I’m Vipin Chauhan today I’m going to share a Project Report on Secant Pile Construction Lets go and know about “Secant Pile Construction Project Report Download “

What is Secant Pile Construction

Let’s know about What is Secant pile construction generally secant piles are formed by constructing intersecting reinforced concrete piles.The secant piles are reinforced with either steel rebar or with steel beams and are constructed by either drilling under mud or augering. Here Primary piles are installed firstly with secondary (male) piles constructed in between primary (female) piles once the latter gain sufficient strength. Pile overlap is typically in the order of 3 inches (normally 8 cm). In a tangent pile wall, there is no pile overlap as the piles are constructed flush to each other. Secant pile construction constructing in the urban area.

In situ pile retaining walls are very popular due to their availability and practicability. There are different types of pile walls contiguous (or intermittent) bored pile construction, (spacing between the piles is greater than the diameter of piles)

Secant bored pile walls are made by keeping spacing of piles less than the diameter (S<D). It is a watertight wall and it may be more economical as compared to a diaphragm wall in small to medium scale excavations due to the cost of site operations and bentonite plant.

Techniques of Construction of Secant Pile Construction

The traditional construction techniques for cast-in-situ concrete retaining walls have included the following given principals which are:

  • Contiguous bored pile walls
  • Secant bored pile walls
  • Diaphragm walls

Advantages of Secant Piles Construction

The redevelopment of inner-city sites in recent years has highlighted many environmental, design and site restrictions.

The ability of secant pile construction techniques to overcome these constraints has led to increased use of secant pile walls to form basements and other underground structures.

  • Noise: comparatively secant piles methods are more adaptable.
  • Wall plan geometry: As site values increase, the pressure to use all available space within basements has become intense. Sites are often sandwiched between existing buildings, and walls are placed in close proximity to adjacent structures or roads.
  • Can be built in industrial complexes where access, headroom and restriction on vibration may make other methods such as steel sheet piling or diaphragm walling less suitable.
  • Suited for all types of soil but penetration through boulders may be difficult and costly.
  • Length can be varied to suit ground conditions.
  • Large diameters are possible.
  • Inclined walls can be constructed.
  • Increased wall stiffness compared to sheet piles.

Disadvantages of Secant Pile Construction

The main disadvantages of secant pile walls are:

  • Verticality tolerances may be hard to achieve for deep piles.
  • Total waterproofing is very difficult to obtain in joints.
  • Increased cost compared to sheet pile walls.

Advantages of Secant Pile Walls are:

  • Increased construction alignment flexibility.
  • Increased wall stiffness compared to sheet piles.
  • Can be installed in difficult ground (cobbles/boulders).
  • Less noisy construction.

 Disadvantages of secant pile walls are:

  • Verticality tolerances may be hard to achieve for deep piles.
  • Total waterproofing is very difficult to obtain in joints.
  • Increased cost compared to sheet pile walls.

Secant pile wall design when steel beams are used involves the use of weaker than normal concrete. The pile that is lagging the wall between two main beams has to be examined for shear and compression arching.
