Computerized grouting design and control

Anyone who has been involved in a grouting project will retain the sad memory of overflowing shelves of files containing countless shift reports, grouting records, etc., and days or Weekson the drawing board, preparing the summary graphics needed to estimate the ground response and workmanship, Without mentioning the problem of preparing the design in the first place, and abstracting grout quantities, or last-minute amendments to deal with surprise discoveries. This was the challenge which prompted the leading specialist companies to equip themselves with electronic aids which quickly became standard tools in dealing with the requirements of major grouting jobs. They are present at every level of operations, from the initial design (for setting out borehole patterns and calculating grout quantities) to on-site control of the grout pumps and data collection, to verification of the quality of the finished job and work rates. The paper describes the components of the computer system for the typical grouting project.
