| Abstract: | The paper introduces the foundation of the quality test and the remedial measures of the rotary bored pile.In order to identify causes of defects emerged during the rotary bored pile construction;an example is presented to discuss some remedial measurements to sediment and segregation.Practical application shows that the treatments of the high pressure grouting and spinning can strengthen the vertical bearing capacity of the piles and remedy the defects. |
