Ground Improvement by Jet Grouting Techniques
The main purpose of this Bachelor’s thesis was to study the designing and construction process of soilcrete executed by various techniques of jet grouting. The thesis serves as a quick guide on understanding performance and limitations of improved soil, based on the jet grouting reported literature. Another aim of the thesis was to understand the execution and quality control process of various jet grouted projects that have been carried out in Finland. In the first part of the thesis a general overview of Single fluid system, double fluid system, triple fluid system and their variations are presented. The engineering properties of soilcrete strongly depend on several parameters used. They are discussed in the second section of the thesis. The final part introduces the practice of jet grouting in Finland. Although Jet grouting is an ideal ground modification technique compared to reinforcement and ground treatment method, the complex operation makes this technique limited in understanding the whole process precisely. To understand the jet grouting process properly the effects of several parameters on soilcrete’s physical and mechanical properties should be studied carefully. Laboratory tests are recommended to estimate the theoretical values required for the designing process. It is also recommended to construct the trial soilcrete directly on the site before the main jet grout operation. since jet grouting construction is not visibly possible to control like in other construction, the state of art in quality control process requires a great deal of planning, monitoring and execution in every stage of construction process to achieve the desired outcome.
