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

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Zhuohang Lian; [2022]
    Nyckelord :Rock engineering; Rock grouting; Variable injection pressure; Dynamic grouting technique;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Bowen Meng; [2021]
    Nyckelord :Dynamic grouting; filtration; rheology; grouting phase;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Jord- och bergmekanik; KTH/Byggvetenskap

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

    Sammanfattning : 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. LÄS MER
