Abstract
The utility model discloses a portable rill erosion flow collecting groove, comprising a flow collecting groove, a flow discharging pipe and two baffles, wherein the flow discharging pipe is connected at the lower part of the flow collecting groove; the two baffles are connected at two sides of the flow collecting groove; and the flow discharging pipe is connected with a flow collecting barrel by an external water pipe. In the portable rill erosion flow collecting groove, the volume is small, the weight is light, the carrying is convenient, the distribution and the installation can be fast carried out; and the portable rill erosion flow collecting groove can adapt to complex soil and microrelief conditions in the field such as sloping farmlands, forest lands, grass lands and the like, and guarantee effective observation to the rill erosion under various flow conditions, therefore, the fast development of large quantity of multi-point simulation tests is realized and the testing efficiency is improved.
Description
Technical field
The utility model relates to a kind of experimental provision, is specifically related to a kind of portable rill erosion afflux groove.
Background technology
Rill erosion is the important form of domatic water erosion.Rill erosion is after slope runoff converges into strand shape current soil separation and the carrying that forms tiny groove and cause to be washed away on ground.The agent of erosion of rill current and carrying capacity cause rill erosion intensity far above raindrop sputter and sheet erosion much larger than the agent of erosion and carrying capacity that raindrop impact and domatic sheet of water are had.The external domatic upward rill erosion amount of sand soil that studies show that is 40 times of interrill erosion amount.Chinese scholar draws in the rill erosion district based on location observation, field study and the indoors artificial rainfall data in loess hill gully, northern Shensi district, the rill erosion amount can account for 74% of total amount of erosion, in rill shallow gully erosion district, the rill erosion amount generally accounts for 12～30% of shallow gully erosion amount, and maximum can reach more than 40%.The observed result of Zi Zhou runoff testing station, Shaanxi runoff plots shows that 45%～60% runoff yield heavy rain generation rill is arranged every year, and the rill erosion amount accounts for 68%～91% of total amount of erosion.Because rill erosion has so important contribution to the erosion caused by sloping surfaces, therefore study rill erosion process and mechanism for preventing erosion, it is significant to carry out comprehensive reclamation to river basin.
The main method of research rill erosion at present is to adopt artificially-simulated rainfall and simulation runoff, excavates rill big Tanaka and carries out various tests.Also there is the researcher to intend the generation evolution of rill at indoor soil box patrix.These tests have been played vital role for the research that promotes rill erosion, but also have the process of the test complexity, the deficiency that set-up procedure is very long, and efficient is lower when particularly carrying out a large amount of open-air site tests for needs.
The utility model content
At above shortcomings part in the prior art, the utility model provides a kind of portable rill erosion afflux groove.
The utility model is achieved in that
A kind of portable rill erosion afflux groove is characterized in that comprising an afflux groove, outflow tube and two baffle plates compositions, and outflow tube is connected the bottom of afflux groove, and two baffle plates are connected afflux groove both sides, and outflow tube is connected with the afflux bucket by external water pipe.
Further scheme is: described afflux groove is connected with outflow tube with downward-sloping 5 to 15 ° angle.
Further scheme is: described afflux groove top one side is provided with the end face of an inclination.
The portable rill erosion afflux of the utility model groove, afflux groove top adds the end face of an inclination, prevents that rainfall from directly entering in the groove, and effect is measured in influence.The afflux groove can be finished the collection of rill flow silt by being connected with the head piece that goes out of rill.The afflux groove left and right sides is welded a rectangle baffle plate respectively, is used for inserting in the test soil body, plays the fixed set chute.The afflux groove is connected with outflow tube with downward-sloping 5 to 15 ° angle, to reduce the alluvial of silt in the afflux groove.Weld circular rising pipe in bottom, afflux groove left side at last, realize being connected with the transition of external pipe.
The utility model volume is little, in light weight, be easy to carry, can arrange installation fast, be adapted to open-air complicated soil and mima type microrelief condition such as sloping arable land, forest land, meadow, and can guarantee under multiple flow condition can both be to effective observation of rill erosion, thereby realize that a large amount of multiple spot simulation tests carries out fast, improves test efficiency.

Fig. 3 is the utility model afflux groove longitudinal profile synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in accompanying drawing 1,2,3, a kind of portable rill erosion afflux groove, comprise an afflux groove 4, outflow tube 5 and two baffle plates 3 compositions, outflow tube is connected the bottom of afflux groove, afflux groove 4 is connected with outflow tube 5 with downward-sloping 5 to 15 ° angle, two baffle plates are connected afflux groove both sides, and outflow tube 5 is connected with afflux bucket 7 by external water pipe 6, and afflux groove 4 tops one side is provided with the end face 8 of an inclination.
In use, select the rill 2 on nature or artificial domatic 1, afflux groove 4 can be finished the collection of rill flow silt by being connected with the head piece that goes out of rill.The afflux groove left and right sides connects a rectangle baffle plate respectively, is used for inserting in the test soil body, plays the fixed set chute.The afflux groove is connected with outflow tube with downward-sloping 5-15 ° angle, to reduce the alluvial of silt in the afflux groove.
