  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. State of the Art Report on Cement Based Grout Properties and Dynamic Grouting

    University essay from KTH/Jord- och bergmekanik

    Author : Bowen Meng; [2021]
    Keywords : Dynamic grouting; filtration; rheology; grouting phase;

    Abstract : Dynamic grouting in rock mass has been studied since 1985 while desired penetration in rock masses with fine fractures is still a challenge because of uncertainty and complexity in the grouting process. This has attracted the attention of researchers in different countries and regions, especially in some Nordic countries such as Sweden. READ MORE

  4. 3. Application of Dynamic Grouting to Improve the Grout Spread Using Varying Aperture Long Slot (VALS) : AN EXPERIMENTAL STUDY

    University essay from KTH/Jord- och bergmekanik; KTH/Byggvetenskap

    Author : Robabeh Hosseini; Yalta Steven; [2018]
    Keywords : grout penetrability; filtration tendency; varying aperture long slot; sealing; cement-based grout; dynamic grouting; bruksinträngningsförmåga; filtrationstendens; VALS; tätning; cementbaserade injekteringsmedel; dynamisk injektering;

    Abstract : In the past centuries, grouting has been one of the most common techniques in geotechnical engineering to strengthen and seal underground structures. Concerning increasing demands for tightness and cost efficiency, cement-based grout has been one the most frequent used materials. READ MORE

  5. 4. Experimental Evaluation of the Effects of Dynamic Pressure on Improving Cement-based Grout Penetrability : A study performed with the short slot

    University essay from KTH/Jord- och bergmekanik

    Author : Anastasios Mentesidis; [2015]
    Keywords : penetrability; filtration; erosion; cement-based grout; variable dynamic grouting;

    Abstract : The increasing need for watertight underground works, such as tunnel excavations, has sparked an interest in a number of research studies with grout penetrability being the focus. The research has so far contributed to a deeper understanding regarding the assessment of a successful grouting operation from different perspectives such as choice of equipment, material properties, phase planning and performance.
