Abstract
The utility model discloses a rainfall erosion monitoring groove, which comprises a rectangular frame both the length and the width of which are 0.35m. The height of the rectangular frame is 0.1m. A collection groove is welded on one side of the rectangular frame. A rabbet of the collection groove is lower 0.5cm than a frame of the rectangular frame. The collection groove is connected with a guide tube. The guide tube is connected with a guide bucket by an external water pipe. The rainfall erosion monitoring groove can effectively separate runoff erosion from rainfall erosion in the erosion process of a sloping surface, also does not influence the re-erosion process of erosion sediment so as to realize scientific simulation on the rainfall erosion process, can completely and effectively collect runoff sediment generated by the rainfall erosion, guarantees accurate measurement of rainfall erosion volume and provides scientific technical means for researching the rainfall erosion mechanism and constructing a soil erosion physical model.
Description
Technical field
The utility model relates to the runoff plots of measuring rainfall erosion in a kind of soil and water conservation, is specifically related to a kind of rainfall erosion monitoring groove that is used to measure domatic rainfall erosion.
Background technology
Domatic water erosion process is the mechanism of the rainwash and the domatic soil of rainfall and generation thereof.Before 60 years, it is that the rainfall dispersion disperses to form with four mechanisms of carrying with carrying and runoff that Ellison just once proposed domatic water erosion process.This understanding became the basis of domatic water erosion process research afterwards.But because rainfall dispersion and carrying and runoff disperse to take place simultaneously on domatic with four mechanisms of carrying, not only interact but also influence each other, under the current experiments technical conditions, be difficult to independent studies is carried out in its separation.At present relevant erosion process experimental simulation research mostly is the experimental simulation of the erosion caused by sloping surfaces mode, and as sputter, sheetflood (interrill erosion), rill erosion etc., erosion action does not separate fully with runoff with the rainfall erosion effect in this research.
The runoff observation on plots method is the classical way of the research soil erosion, and according to the research purpose difference, the size of runoff plots is in variation between several square metres to hundreds of square metres of zero points, and wherein area is less than 1m
2Miniature runoff plots obtained using more widely at aspects such as the soil hydrology and the research of the erosion caused by sloping surfaces mechanism and key parameter obtain.Many researchers adopt area less than 1m
2Miniature runoff plots studied soil erodibility, domatic rainfall runoff yield process, domatic hydrodynamics characteristic, the influence that forest land, farmland, all factor pair runoff yields of bare area last, soil crust with infiltrate etc., but rainfall erosion process is significantly different with above-mentioned research existence, directly adopts these devices, can't effectively separate rainfall erosion and runoff and corrode, reach the target of simulated rainfall erosion process.In addition with the similar research device of mensuration rainfall erosion, as the sputter cup, though the sputter dish can separate rainfall erosion and runoff corrodes, but because assay method obviously differs too big with real rainfall erosion process, can't ensure the mensuration of secondary sputter and traction load, cause rainfall erosion quantitative determination imperfection.
The utility model content
The technical problems to be solved in the utility model provides a kind of device of domatic rainfall erosion that is used for accurately measuring.
The utility model is achieved in that
A kind of rainfall erosion monitoring groove, the rectangle frame that comprises a long and wide 0.35m of being, the frame height of rectangle frame is 0.1m, at one side of rectangle frame welding afflux groove, afflux groove notch is lower than rectangle frame frame 0.5cm, the afflux groove is connected with mozzle, and mozzle is connected with the afflux bucket by external water pipe.
Further scheme is: described afflux groove is connected with mozzle with downward-sloping 5 ° angle.
Further scheme is: described afflux groove one side is provided with the end face of an inclination.
During concrete the use, groove 2 integral body are monitored in rainfall erosion imbed natural or artificial domatic 1, identical in sub-district periphery soil surface treatment and the sub-district, reach inside and outside unanimity.Frame 3 exceeds face of land 0.5-1cm, guarantees that the top runoff can not enter the sub-district generation and wash away, and has reduced the disturbance of rainfall erosion monitoring groove to the erosion caused by sloping surfaces process simultaneously again.Runoff and sediment enters afflux groove 4 by rainfall erosion monitoring groove 2, passes through mozzle 5 again, and external water pipe 6 enters afflux bucket 7 at last.
The present invention adopts the thinking of sampling side, has designed a kind of rainfall erosion monitoring groove, and it is arranged on the domatic soil body.Specification by the control sub-district guarantees that rainfall erosion monitoring groove inside runoff can not take place corrodes, height by the outstanding ground of control rainfall erosion monitoring trough rim frame, guarantee that sputter silt can transition mutually inside and outside groove is monitored in rainfall erosion, realize the erosion once more of sputter silt, the height of frame makes the lucky and external isolation of rainfall erosion monitoring groove, outside runoff can't flow into rainfall erosion monitoring groove, and the runoff of rainfall erosion monitoring groove inside also can't flow directly to the outside, can only be collected mensuration by the afflux groove that the groove below is monitored in rainfall erosion.Rainfall erosion monitoring groove is inner owing to the mode of silt by runoff is collected, both to have comprised suspended load and traction load because the silt that rainfall erosion produces will be collected in the lump with runoff in the runoff, more complete to the mensuration of rainfall erosion amount.By the end face of an inclination is set on the afflux groove, basic elimination directly is splashed into rainfall, runoff and the silt of afflux groove, and runoff that assurance is collected and silt from rainfall erosion monitoring groove inside, are realized the accurate simulation to rainfall erosion process fully.
Pass through the utility model, the runoff that can effectively separate in the erosion caused by sloping surfaces process corrodes and rainfall erosion, do not influence simultaneously the erosion process again of erosion sediment, thereby realize science simulation to rainfall erosion process, and can completely collect the runoff and sediment that rainfall erosion produces effectively, guarantee the accurate mensuration of rainfall erosion amount,, make up the technological means that soil erosion physical model provides science for research rainfall erosion mechanism.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of rainfall erosion monitoring groove, the rectangle frame 2 that comprises a long and wide 0.35m of being, the frame 3 of rectangle frame 2 highly is 0.1m, at one side of rectangle frame welding afflux groove 4, afflux groove notch is lower than rectangle frame frame 0.5cm, and afflux groove 4 is connected with mozzle 5 with downward-sloping 5 ° angle, and mozzle 5 is connected with afflux bucket 7 by external water pipe 6.
As shown in Figure 2, be provided with the end face 8 of an inclination in afflux groove one side, end face can cover afflux groove top fully, and basic elimination directly is splashed into rainfall, runoff and the silt of afflux groove.
During concrete the use, groove integral body is monitored in rainfall erosion imbed natural or artificial domatic 1, identical in sub-district periphery soil surface treatment and the sub-district, reach inside and outside unanimity.Frame 3 exceeds face of land 0.5-1cm, guarantees that the top runoff can not enter the sub-district generation and wash away, and has reduced the disturbance of rainfall erosion monitoring groove to the erosion caused by sloping surfaces process simultaneously again.Runoff and sediment enters afflux groove 4 by rectangle frame 2, passes through mozzle 5 again, and external water pipe 6 enters afflux bucket 7 at last.
