  • 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.
  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • 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 modified polyacrylamide drilling fluid?
  • Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
