Description

Technical Field

[0001] The utility model relates to the technical field of highway engineering, in particular to a pressurizing device for detecting raw materials of highway engineering. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. Concrete is often used in the construction process of highways. Before the concrete is put into use, it is necessary to conduct compression and flexural tests on the concrete blocks. Compression or flexural tests require extrusion tests on the concrete. After the test, the concrete blocks will be damaged due to pressure, which can easily cause splashing of concrete blocks and cause safety hazards. At the same time, since the test bench has a certain height, but the weight of the concrete test blocks is heavy, it is difficult for workers with less strength to lift them onto the test bench, which is time-consuming and laborious.
