Abstract: The invention relates to a soil freezer (100) which allows undisturbed sampling by artificial soil freezing system in the field of geotechnical engineering. The invention particularly relates to local artificial ground freezer which allows undisturbed sampling in granular soil dominated layers (mostly sand and gravel) without damaging the natural conditions, and comprises a cooling unit (110), gas delivery pipes (113), a freezing piping system (120), pipes with steel shoes (121), end connection capillaries (122), a gas discharge-fill valve (112) and an installation apparatus (130).

Abstract: The invention is an application that completely alter the operating principle and load transfer mechanism of the anchorage technique used in the field of civil engineering, in particular at the excavation bracing and slope stability applications with a novel root zone apparatus.

Abstract: The invention relates to a jet anchor which ensures the fixation of the lateral support elements on the surface to mass formed by high pressure jet injection with purpose of providing stabilization of the excavation surface during excavation support and slope stability works, said jet anchor provides the combined usage of anchor body (120), ducted cutting wing (140), connectors, rigid wing opening plate (130), rope pulling apparatus (110), guide pipe elements (150) with new anchor equipment and jet grouting system and thus obtaining strength increased anchor element.
