Description

Technical Field

[0001] The invention relates to the field of vegetation concrete anti-scour simulation test, and in particular to a vegetation concrete anti-scour intelligent test device and a use method. Background Art

At present, the research on the mechanical properties, matrix ratio, matrix fertility, root-soil effect of vegetation concrete is relatively mature, but there are few studies on its anti-scouring ability. According to engineering experience, vegetation concrete can have good anti-scouring ability one week after construction, but in the early stage of construction, the cement hardening effect in the base material has not been fully exerted. Once the surface is unstable or a large amount of sediment erosion occurs under the action of heavy rainfall, it can cause soil and water loss on the slope, which may cause safety hazards in serious cases.

[0003] The current anti-scour tests of vegetation concrete are relatively simple and complicated to operate. At the same time, the equipment mode is relatively single, the data recording is relatively cumbersome, the variable control steps are mixed, and it is not flexible to transform and simulate different slopes (slopes, slope types) and combine with local rainfall conditions, etc. This leads to a large difference between the measured data and the actual situation. At the same time, when studying the scour conditions in different scenarios, more molds have to be made, resulting in a waste of materials and manpower.

[0004] In summary, it is very necessary to invent an intelligent test device for anti-scouring of vegetation concrete that can flexibly simulate different local slopes and rainfall conditions and integrate scouring material drying and weighing. Summary of the invention
