1. 1. Evaluation of high pressures in grouting using RTGC - a case study

   University essay from KTH/Jord- och bergmekanik

   Author : Simon Nikolaev; [2015]
   Keywords : grouting; grouting pressures; tunnelling project; RTGC-theory; injektering; injekteringstryck; tunnelprojekt; RTGC-teorin;

   Abstract : “Real time grouting control method” är ett koncept för att övervaka och bedöma spridningen av injekteringsbruk under injektering. Målet är att kunna använda penetrationsavstånd som stopkriterium och att kunna övervaka hur injekteringsarbetet fortskrider i realtid, vilket skulle göra injekteringsarbetet mer tids- och kostnadseffektivt.
