Abstract
The utility model belongs to the technical field of geotechnical engineering model tests and provides a slide location mechanism of a geotechnical engineering anti-explosion structure model test device. Four lateral confinement cases are arranged at the edge of an underground explosion pit in a way that each two cases face each other and are perpendicular to each other, and form a cuboid explosion test model space with the underground explosion pit. Four wheels (26) are arranged on lateral confinement case bottom plates (1). The slide location mechanism comprises bidirectional jack oil cylinders (15), guide rails (17) and locating blocks (19). Each bidirectional jack oil cylinder (15) is arranged corresponding to each lateral confinement case, and jack pull rods (16) of bidirectional jack oil cylinders (15) are connected with the lateral confinement cases (23). Two rail grooves are arranged corresponding to each lateral confinement case, each rail groove is provided with a guide rail (17), and the locating blocks (19) are arranged on a rail close to the edge of the underground explosion pit. Combining and separating of the four lateral confinement cases are realized when an explosion test is carried out.
