Abstract

The invention discloses a compressive and uplift test device for a reinforced concrete pile, which adopts a jack for applying vertical pressure and a jack for applying vertical uplift force, and is characterized in that the jack for applying vertical pressure is fixed at the upper end of a test pile to be tested; a first steel beam spaced from the upper end of the vertical pressure applying jack is arranged at the upper end of the vertical pressure applying jack, a second cross beam is arranged at the upper end of the first steel beam, and the vertical upward pulling force applying jack is fixed to the upper end of the steel beam. The upper end of the vertical upward pulling force applying jack is provided with a third steel beam which is arranged at an interval with the upper end of the vertical upward pulling force applying jack, the upper end of the third steel beam is provided with an anchor pulling plate, the anchor pulling plate is connected with the to-be-tested test pile through an anchor bar, and the vertical pressure applying jack and the vertical upward pulling force applying jack are used for achieving compression resistance and pulling resistance respectively. The device has the advantages of simple structure, capability of realizing compression resistance and pull-out test, and great simplification of experimental equipment.

Description

technical field [0001] The method relates to the technical field of on-site compression and pullout tests of reinforced concrete piles, in particular to a compression and pullout test device for reinforced concrete piles. Background technique [0002] In recent years, with the development of society, the scope of application of pile foundations has become wider and wider, not only in the construction of houses, but also in bridges, slopes and other fields. Pile foundations are suitable for The wide range of characteristics is destined to make the pile bear various loads in the process of functioning. The most researched and tested is the vertical pressure of the pile foundation, but in actual engineering, there are pile foundations that bear both tension and compression loads. For example, under the condition of periodic changes in groundwater, the pile foundation is subject to both the pressure of the superstructure and the buoyancy generated by the change of groundwater. T...
