Compression test device for highway engineering

Abstract

A compression test device for highway engineering comprises a bearing table, a mounting frame, a pressure roller, a test assembly, a side supporting frame and a bearing block limiting assembly. The two sets of mounting frames are arranged on the two sides of the lower end of the bearing table correspondingly; the pressure roller is arranged below the bearing table and is rotationally connected with the mounting frames on the two sides; the test assembly is arranged on the bearing table; the side supporting frames are arranged on the two sides of the bearing table, moving wheels are arranged atthe bottom ends, and height adjusting pieces are arranged at the upper ends. The bearing block limiting assembly is arranged at the upper end of the bearing table. The dust settling part is arrangedto settle dust on the road surface, and unclear pictures during video recording are avoided; the striking piece and the pressure roller are matched to respectively detect small-area and large-area compression resistance conditions; the height of the camera is adjusted as required, so that a better shooting effect is achieved; the bearing block is limited from the upper part and the side part, so that the influence on the test accuracy due to gravity center shift is avoided, and the pressure is convenient to change.

Description

technical field [0001] The invention relates to the field of test equipment for road engineering, in particular to a compression test device for road engineering. Background technique [0002] The strength design of highway concrete adopts the 28-day flexural tensile strength of cement concrete. The design flexural tensile strength of the light traffic load class is 4.OMpa, the medium class is 4.5Mpa, and the heavy, extra-heavy, and extremely heavy classes are above 5.OMpa. The flexural tensile strength of 4.OMpa corresponds to C25, 4.5Mpa corresponds to C30, 5.OMpa corresponds to C35, and 5.5Mpa corresponds to C40. At present, the compression resistance of highway engineering needs to be detected through experiments, but the existing detection methods of highway engineering compression test devices are relatively new, the settings are rigid, and the detection results are not accurate. [0003] In order to solve the above problems, this application proposes a compression te...
