Description
Technical field
The utility model relates to a kind of soil erosion simulated rain trails device, particularly relates to a kind of lab simulation soil erosion small-sized test soil box.
Background technology
Soil erosion is the serious ecological problem of China." China Environmental State Bulletin in 2010 " shows, and China's soil erosion area has accounted for 37.2% of territory total area, reaches 356.92 ten thousand km
2.Along with country is to the attention of bringing soil erosion under control, China is provided with typical monitoring point observation status of soil erosion in the major area of soil erosion, have accumulated a large amount of observation datas, this provides very large support to carrying out soil erosion disaster.Before mid-term in 20th century, natural rainfall is depended on more to the research of the soil erosion, due to natural rainfall observation station need chronic, and various factors is difficult to manual control, brings certain difficulty to the collection of data and analysis, can not satisfy the demand far away.
For this reason, some countries such as USSR (Union of Soviet Socialist Republics), Japan, the U.S., Australia successively establish the various artificial simulated rainfall rooms such as the soil erosion, runoff gathering, slip erosion, to make up the deficiency of field trial.Its advantage: (1) can simulate the natural rainfall of varying strength, even the extra torrential rain of centuries one chance also can reproduce in laboratory, substantially reduces the test period.(2) can use modernization test instrumentation, also not have problems with water, thus test level is higher, can obtain high-quality experimental data.(3) can strict Control release condition, for the observational study soil erosion generation evolution process and and each influence factor between inherent mechanism, have an enormous advantage.
The soil box all too simplification that current domestic manual simulation's water and soil balance rainfall system is used, the soil box used in ordinary test is divided into small-sized soil box and big-earth-groove.Small-sized soil box specification is generally at about 1*0.5*0.3, and its volume is smaller, makes simple, easy to use, but not easily moves after loading soil, and not easily place when simulating slight slope angle.Some large-scale rainfall simulation experiment Rooms big-earth-groove specification used is generally about 5*1*0.8, and volume is large, can simulate the observation overland flow volume morphing that the larger situation of length of slope can be careful, not easily move general motor vehicle and draw.But the parameter of the slight slope that current two class soil boxs measure in test is more conventional, as run-off, sediment yield and a stream time etc., these parameters are all observation slight slope surface and obtain, and all have no way of obtaining for the parameter of inside soil body.And the runoff and sediment process of many parameters of slight slope inside to research slight slope surface has very important effect.Process of loading when using soil box to carry out rain test is the most loaded down with trivial details, needs layering to load compacting, especially seeming when carrying out different soils contrast test more loaded down with trivial details, finally affecting test progress.
In sum, existing lab simulation water and soil balance is tested soil box used and is existed following not enough: (1) existing soil box surrounding is all make with steel plate, can not the Wet Out must seeing below slight slope face directly perceived; (2) existing slope groove is time-consuming, especially more loaded down with trivial details when carrying out different soils contrast test when loading; (3) existing small-sized soil box not easily moves, and not easily simulates slight slope angle; (4) parameter observed according to existing soil box is confined to slight slope surface, has no way of learning to the parameter of inside soil body.
