Compared with prior art, major advantage is this utility model: rainfall on slope land drainage test mould of the present utility model
Intend device and formed domatic by filling the soil body at lower portion, and adjust gutter height and row by the lifting support at two ends
The water gradient, the drainability in simulated rainfall conditions Caused by Sloping Surfaces gutter, thus provide reference for the design of slope drainage ditch, there is weight
The significance of scientific research wanted, and simple in construction, processing cost is low, it is easy to producing and popularization and application in teaching.
Accompanying drawing explanation
Fig. 1 is this utility model structure chart；
Fig. 2 is the structural representation that in this utility model, lifting support supports gutter；
In attached Fig. 1 and 2, labelling is described as follows:
1-framework；2-is domatic；3-faucet；4-shower nozzle；5-gutter；6-support；7-ruler.
Detailed description of the invention
Being described in further detail device of the present utility model below in conjunction with the accompanying drawings, not quite clear part is shown in utility model content
Part.
As it is shown in figure 1, a kind of rainfall on slope land draining experimental simulation device, including a framework 1, described framework 1 is by filling
The soil body forms one domatic 2；Top, the described slope of domatic 2 is provided above faucet 3, and this faucet 3 is provided with for simulating fall
The shower nozzle 4 of water；The bottom, slope of described domatic 2 is also equipped with gutter 5；Described gutter 5 one end or two ends equal
Supported by the lifting support 6 of adjustment height, by arranging the drainage grade in the Height Adjustable gutter 5 of lifting support 6.
As in figure 2 it is shown, the one end in gutter 5 is supported by lifting support 6, adjust the height of lifting support 6, just
The drainage grade in gutter 5 can be adjusted, coordinate rainfall draining experiment, make experimental result the most accurate.
The a length of 1.772m in gutter 5, is 33.8cm deeply, makes for transparent material, and it is desirable that the right side of framework 1 is additionally provided with one
The ruler 7 put；The convenient degree of depth being used for measuring silt soil of ruler 7, is arranged to transparent by gutter 5, is beneficial to observe, Er Qiezhi
Chi can be placed in the right side of framework 1 and is easy to pick and place.
The a height of 1.5m of framework 1, a length of 2m, a width of 1.772 meters；By Tanaka's soil body in framework 1, ultimately form domatic；
And in order to make result of the test more accurate, on domatic 2, it is also provided with grass by plant；And the lower surface of shower nozzle 4 is arranged
Uniformly spray orifice, can accurate simulated rainfall draining.
This utility model also provides for the operational approach of a kind of rainfall on slope land drainage test analog, the steps include:
A, according to erecting device shown in Fig. 1 and Fig. 2, in framework, fill the soil body, and ultimately form domatic, cloth on domatic
If Caulis et Folium Polygalae Tenuifoliae, the actual domatic environment of simulation；
B, after on-test, open faucet, require to control water yield according to testing program, carry out domatic rainfall on slope land,
After certain time, close faucet, measure the thickness of mud in gutter by ruler；
C, thickness according to mud determine whether to adjust the gradient in gutter, if desired, the silt then cleaned out in gutter
Mud, readjusts support height, opens faucet, then carries out the most domatic rainfall on slope land, after certain time, closes faucet,
Measuring the thickness of mud in gutter by ruler, according to testing program requirement, method carries out test of many times like this, and then is given
The rational gradient in gutter；
D, tested after, process and obtain data, and with the mud in scoop and hairbrush cleaning gutter, it is ensured that on inwall
There is no attachment, to carry out test next time.
This rainfall on slope land drainage test analog is formed domatic by filling the soil body at lower portion, and passes through support
Adjust gutter height, the drainability in simulated rainfall conditions Caused by Sloping Surfaces gutter, thus provide ginseng for the design of slope drainage ditch
Examining, have important significance of scientific research, and simple in construction, processing cost is low, it is easy to producing and popularization and application in teaching.
Specific embodiment described in this specification is only to this utility model spirit explanation for example.This practicality is new
Described specific embodiment can be made various amendment or supplements or use by type person of ordinary skill in the field
Similar mode substitutes, but without departing from spirit of the present utility model or surmount model defined in appended claims
