摘要
The present disclosure relates to the technical field of civil engineering, in particular to a test device for mechanical properties of a pile-soil contact surface. The upper ends of the two columns are fixedly connected with a top beam, and the support plate fixedly installed between the two columns is arranged below the top beam. A bottom plate provided between the two columns is fixedly installed under the support plate, and a film box is embedded between the support plate and the bottom plate. The film box includes a circular rubber film cylinder, a bottom supporting board and a cover plate. A vertical loading device for applying vertical pressure to the pile is provided at the middle of the top beam. The present disclosure can realize different experimental comparisons, by pushing the inserted bar down and fixing, pushing the bump out from the outer ring surface of the adjustment shaft via the connecting rod, thereby correspondingly increasing the diameter of the winding of the lower tensile band, so that the lower tensile band is wound more when it is rotated one turn, so as to provide greater side thrust. By changing the test method and then conducting comparative analysis, the test data is objective and accurate.
