  1. 1. Analysis of rock grouting with variable injection pressure

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Zhuohang Lian; [2022]
    Keywords : Rock engineering; Rock grouting; Variable injection pressure; Dynamic grouting technique;

    Abstract : Rock grouting is an effective technique frequently used in rock engineering to reduce  groundwater ingress and increase the stability of surrounding rock mass. The real time grouting control (RTGC) is one of widely used  analytical models to predict the grouting process. READ MORE

  3. 2. Evaluation of Real Time Grouting Control Theory Using a Varying Aperture Long Slot- VALS

    University essay from KTH/Jord- och bergmekanik

    Author : Elizaveta Pronina; [2018]
    Keywords : Grouting; Real Time Grouting Control theory-RTGC; Penetration Length; Cement-Based Grout; Varying Aperture Long Slot – VALS; hydraulic aperture;

    Abstract : The main goal of the grouting is to seal the fractures in the rock mass,improve the strength properties of the rock mass and decrease deformability. However,the overuse of the grouting should be avoided due mainly to economic reasons,optimizing the project time and sometimes severe environmental issues. READ MORE

  4. 3. 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.
