  1. 21. Evaluation of "GIN method" at Two fans of City banan project in Stockholm

    University essay from KTH/Jord- och bergmekanik

    Author : Mehran Neshati Sani; [2015]
    Keywords : grouting; GIN method; cement; jacking; penetration; pressure; volume intake;

    Abstract : An underground installation with too much inflow can lead to dangerous consequences for around environment, therefore a well-sealed construction results in appropriate inflows. To mitigate movement of ground water table in underground constructions, it is necessary to seal the rock mass by grout injection. READ MORE

  3. 22. 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.

  4. 23. 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.

  5. 24. Evaluating and Comparing of Three Penetrability Measuring Devices : Modified Filter Pump, Modified Penetrability Meter, and Short Slot

    University essay from KTH/Jord- och bergmekanik

    Author : Saman Ali Akbar; Manar Al-Naddaf; [2015]
    Keywords : grouting; penetrability; filtration; fitter pump; penetrability meter; short slot; cement-based grout;

    Abstract : Rock grouting is a commonly used process for sealing rocks in tunnels to reduce water ingress. In order to achieve sufficient sealing level the grout must effectively penetrate into rock fractures while the limiting factor is filtration of cement based grout. READ MORE

  6. 25. Distributed Thermal Response Test on a Grouted U-pipe Borehole Heat Exchanger

    University essay from KTH/Energiteknik

    Author : Marine Marcucci; [2014]
    Keywords : Ground source heat exchanger; grout;

    Abstract : The expansion of the use of geothermal heat pumps makes the study of their performances a keystone in their development. Several parameters are crucial to design properly a geothermal heat pump. Comparing the theoretical characteristics of a system with the actual ones one the field is part of its understanding.
