Abstract

Poboljšanje odnosno ojačanje tla postalo je sve češća metoda kojom se omogućuje građenje na tlima loših karakteristika. Jedna od najčešće korištenih metoda je tzv. mlazno injektiranje, eng. Jet grouting. Mlazno injektiranje je metoda poboljšanja mehaničkih svojstava tla, gdje se struktura samog tla posve razbija pomoću visokoenergetskog mlaza tekućine dok se čestice tla miješaju (in-situ) s vezivim sredstvom i stvaraju homogeniziranu masu poboljšanih, tj. ojačanih svojstava. U ovom radu opisana je metoda mlaznog injektiranja, mogućnosti primjene, prikaz tehnologije i metode izvedbe. Uz to opisan je projekt poboljšanja tla mlaznim injektiranjem na stadionu NK Osijek Pampas.

Abstract (english)

Soil improvement or reinforcement has become an increasingly common method of allowing poor soil characteristics to be built on. One of the most commonly used methods is the so-called jet grouting. Jet grouting is a method of improving the mechanical properties of the soil, where the structure of the soil itself is completely broken by a high-energy jet of fluid while the soil particles are mixed (in situ) with a binder and produce a homogenized mass of improved, ie reinforced, properties. This paper describes the jet grouting method, application options,technology presentation, and performance methods. In addition, a project on soil improvement by jet grouting at the NK Osijek Pampas Stadium was described.
