Successful pipe jacking demands low skin friction between the ground and the jacked pipe. This is achieved with bentonite lubrication. The bentonite slurry fed into the annular gap fulfils several purposes. It stabilises the annular gap by supporting the surrounding ground and reduces friction contact between ground and jacked pipe. The Bentonite Handbook deals comprehensibly with the relevant aspects of annular gap lubrication: starting with the ground conditions, which are of decisive importance for lubrication, through the rheological properties of the bentonite slurry to the technical components of lubrication technology and lubrication strategy. The use of standardised measuring apparatus is described as well as mixing equipment and the automatic lubrication system. Overview tables with calculations and suggested values for bentonite consumption quantities depending on the prevailing ground conditions and the pipe jacking parameters complete the recommendations. 606 $aUnderground pipelines 615 0$aUnderground pipelines. 676 $a622.361 700 $aPraetorius$b Steffen$01647676 702 $aScho?ßer$b Britta 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910830429403321 996 $aBentonite Handbook Pipe Jacking$93995395 997 $aUNINA
