    • Abstract
  • This paper expounds the technique building "concrete plug" in collapse column with grouting,i.e.selection of the place of "concrete plug",calculation of the thickness,the technology of drilling and grouting,the methods of checking and consolidating "concrete plug".The practicality and expansion are illustrated with an example.
