Using Polyacrylamide (PAM) to Reduce Erosion on Construction

  • 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.
  • Can polymer fluid be used to support pile bores?
  • In terms of excavation size, polymer fluids have been successfully used to support pile bores with a diameter of up to 2.2 m for the Vasco da Gama Bridge project in Portugal. However, collapses have also occurred twice there due to polymer contamination by salts in the ground.
  • Can polymer fluids be used for bored piles in silty fine sand?
  • This paper is concerned with the use of polymer fluids for the construction of bored piles in silty fine sand, a situation which has been found to significantly increase the risk of ‘soft toes' and concrete contamination due to the settling of the suspended soil particles in the fluid.
  • 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
