| Abstract | The Major part of this thesis study deals with the design, working procedure and the efficiency evaluation of grouting in rocks and Solis for strengthening the ground and reducing the water seepage. Four case histories are summarized and discussed to study the performance of grouting. Grouting design techniques are evaluated with respect to the numerous empirical and practical methods. For grouting in rocks the general procedures will be the drilling, the flusning, the water testing and the grouting. For grouting in soils, the general procedures are the drilling, the installation of the tube-a-manchette, the plastic (sleeve) grouting, and the pressure grouting. The choice of drilling machines, drilling bits, and the flushing fluid are discussed. The design of grouting includes the determination of the grouting pattern, the grout material, the grouting pressure etc. The grouting patterns varies from single grout row for temporary structures to multi-grout rows for permanent structures. The spacings among holes can be evaluated from many empirical formulae, case studies to evaluate the applicability of these empirical formulae are included. The choice of grouting material depends on soil and rock properties, grout properties and purposes of grouting. The cement grout is applicable to dam foundation and permeable sand treatment, while the chemical grout (the sodium silicate base grout) is applicable for fine sand. A case study of the grouting for Mass Transit Railway Construction in Hong Kong proves the sodium silicate base grout can be applicable not only for fine sand but also for silty sand by fissure and fracture grouting. Note that the durability of thin cement grout and chemical grout is in doubt, so that the chemical grouting is better be chosen as a temporary treatment. The grouting pressure is generally higher than the overburden pressure for both grouting in rocks and soils. The Case studies presented in this study prove the necessity of grouting pressure to be higher than the overburden pressure. Upheave gauges and automatic recorders for detecting upheaval and high grouting pressure are necessary. All empirical formulae can only act as guidelines, grouting tests are essential to determine the suitable grouting design. The efficiency of the grouting is difficult to be evaluated, and seismic and radar techniques are encouraged to be used. |
