  • What type of polymer is used to construct a pile?
  • To this end, six 0.6-m diameter bored piles (Piles P1–P6) with a length of 10 m were constructed. Three types of polymer, namely (1) polyacrylamide (PAA), (2) carboxymethyl cellulose (CAM), and (3) XAN xanthan gum (XAM), were used for the trial. Bentonite slurry was also used to construct a pile for comparison.
  • What is polyacrylamide used for?
  • Hence, it is an earth-stabilising fluid that is designed for a variety of applications in the geo-construction industry such as tieback anchors, diaphragm walls, horizontal drilling, tunnelling, slurry trenching, drilled shafts/bored piles, and others. 6.1. Polyacrylamide in drilling technology
  • What type of polymer is used in a test pile?
  • Three types of polymer, namely (1) polyacrylamide (PAA), (2) carboxymethyl cellulose (CAM), and (3) XAN xanthan gum (XAM), were used for the trial. Bentonite slurry was also used to construct a pile for comparison. Table 1 summarizes the support fluid information for each pile. Table 1. Summary of Support Fluid and Test Pile Information
  • How many piles were excavated under polymer fluids?
  • To this end, three 1.2-m diameter and 27-m long bored piles were constructed, two of which were excavated under polymer fluids [i.e., (1) Pile P1, and (2) Pile P2] and one under bentonite (Pile B1). The Marsh funnel viscosity of the support fluids, measured prior to use, were 70, 69, and 34 s for Piles P1, P2, and B1 respectively.
