Performance of Bored Piles Constructed Using Polymer ...

May 25, 2015· More recently, Lam et al. (2010a, 2014a) reported that polymer fluids can lead to higher pile shaft resistance compared to bentonite, and that a pile bore open time of up to 26 h does not appear to reduce the performance of piles constructed using polymers.

How to use the polymer for the bore hole

The use of bentonite slurry will be successful depending on stringent control on its properties. Some specifications according to BS EN 1536 are summarized below including specification usually provided by contractors (the properties are of bentonite at 20 o C): The following requirements must comply with the bentonite used in drilling: Density: Density/unit weight of drilling slurry is the ...

bentonite and vinyl polymer, where the bore requires support during excavation. To save on the construction of pile caps they can sometimes be removed altogether by embedding the steel structure directly into the top of large diameter piles. These are known as monopiles. The technique An auger is used to excavate the soils, whilst

Oct 06, 2017· Pile Bore Stability with Polymer Drilling Fluid. This problem occurs even in rotary piling method, like in Chisel–Bailor method, when a relatively short temporary casing is used. Due to difficulties in casing extraction arising out of limitations of machine capacity, kelly, hoisting length and absence of oscillatory mechanism, the casing ...

Which one is better, bentonite slurry and polymeric slurry?

1.3 The piling products considered herein are characterized by the use of polymers, whereby (1) the pile strength or stiffness requires the inclusion of the polymer, or (2) a minimum of fifty percent (50 %) of the weight or volume is derived from the polymer. The type classifications of polymeric piles described in Section 4 show how they can be reinforced by composite design for increased ...

constructed under a polymer fluid and one under bentonite. The difference between the two polymer piles was the pile bore open time; one was concreted within 7.5 h of the completion of excavation (Pile P1) whilst the other was concreted at 26 h (Pile P2). The bentonite pile (Pile B1) was concreted at 7.5 h.

Requirements of Bentonite in Boring of Pile Foundation ...

This specification covers the use of polymer stabilizing support fluids ("slurry") based on SHORE PAC, an easy mixing, water-soluble, polymer supplied as a free-flowing granular material. SHORE PAC earth-reinforcing fluid is designed for use in the construction of bored piles by the slurry-displacement method.

Bored Piling with Polymer - Pacific Highway, Woolgoolga ...

Though the cost of polymer is generally more expensive than bentonite, the use of polymer is increasing because polymer is generally infinitely re-usable and very small amount of polymer is normally required for construction works. The disposal cost of bentonite is quite high while the disposal of polymer can be readily conducted by adding ...
