Roadbed performance testing device

Abstract

The invention discloses a roadbed performance testing device. The roadbed performance testing device comprises a closed box-type main body, a refrigerating machine, an electric heater and a spraying system; an evaporator of the refrigerator and the electric heater are arranged at the top of an inner cavity of the box-type main body; light sources are uniformly distributed around the top of the inner cavity of the box-type main body; spraying heads of the spraying system are evenly distributed on the top and the periphery of the top of the inner cavity of the box-type main body; drainage grooves are formed around the bottom of the inner cavity of the box-type main body; fans are arranged on two adjacent side walls of the box-type main body; a plurality of ventilation openings are evenly distributed in side walls, opposite to the fans, of the box-type main body, and exhaust switches are arranged on the ventilation openings; a data through hole is formed in a side wall of the box-type main body; and a manhole door is arranged on a side wall of the box-type main body. According to the roadbed performance testing device of the invention, the influence condition of the coupling effect of various natural environmental factors on various properties of a roadbed is tested, and then the change conditions of the pavement performance, the degradation performance and the stability of the roadbed are analyzed. The device is beneficial to research on disease mechanisms of roadbed engineering and proposing of disease control measures.

Description

Technical field:[0001]The present invention relates to a test apparatus, and more particularly to a subgrade performance test device.Background technique:[0002]Subgrade projects are directly exposed to natural environments during service, and the effects of light, wind blow, rainfall, temperature change are more serious, leading to different degrees of disease in Subgrade project, such as windy road base slope erosion, temperature The change caused a serious frostf and sinking in the subgrade, and the rainwater flushing causes the collapse of the street, and will be affected by multiple natural factors in the actual work of the subgrade project, further aggravating the occurrence of Subgrade Engineering, seriously affecting the performance of the roadbed project. Reduce the service life of the Subgrade Engineering, while cost a large amount of energy and resource for maintenance.[0003]Over the years, many scholars have studied a lot of research on the influence of the roadbed projec...

Problems solved by technology

However, most studies are based on single natural factors to analyze the changes in the performance of subgrades, which cannot truly reflect the impact of multiple natural factors on subgrade engineering.

Some researchers use computer technology to analyze the influence of multiple factors on the performance of the subgrade through simulation, but there is still a gap between them and the real situation.
