Polymer Support Fluid UK Recent Experience Using Polymer Support Fluids , In recent years Polymer support fluids are increasing being used as a bored pile support fluid, as an alternative to the more traditional bentonite A number of benefits have been...
In stable soil formations, the bearing capacity of bored piles can be increased significantly by enlarging the base area of each pile Belling buckets with retractable cutter arms are used for this purpose...
ABSTRACT Bentonite slurries have been used for over sixty years for the temporary support of excavations such as bored piles and diaphragm walls At intervals over this time polymer products have been tried in place of bentonite but not always successfully...

Over the last five years rotary bored piling with vinyl polymer support fluid has proved to be an economic alternative to bentonite slurry Two case histories in central Glasgow are described in this paper, one for piles founding in granular soils and one for piles founding into bedrock...
Physical modelling of pile is done to find out the uplift capacity of bored pile, for that modelled pile is bored without use of drilling fluid and by using different of bentonite and different of polymer separately and pull out test is performed on the fabricated test set up...
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...
Bored piles can be easily adapted to the various load and soil requirements due to the large variety in diameter and construction techniqu Single pile diameter can vary between 30 and 300 cm , When using the direct flushing method, bentonite or polymer suspension is pumped down to the piles tip through the hollow drilling rod The ....
Polymer is more environment-friendly compared to bentonite, but density of bentonite can be adjusted to be heavier so as to suit greater ground water pressure The residual of bentonite has to be sent out to the designated dumping ground...
How does Polyacrylamide works in Bored Piling? There are two usage in bore piling Polyacrylamide could be used like building glue additive, because of the high viscosity and water retention So it could be mixed in slurry of borehole wall to get better efficiency The cationic polyacrylamide is suggested Slurry is important to protect borehole wall, but surplus slurry need to ,...
