Footpath flow point is to suitable observation and the water of sample collection, and this is more original extensive mode, the water error obtained after shunting
It is very big.Second, shunting pond, it is to build out some contour equidistant cog shape delivery ports by laying bricks or stones above runoff collecting-tank, is obtained wherein
The water of one delivery port.It is only to wait collecting-tank to store full just produce to shunt that this mode is most clearly disadvantageous, not only instantaneity
Poor and water error is also big.Third, multitube shunts, it is equidistantly set in the same horizontal line of runoff collecting-tank or dust-collecting bucket
The equal outlet pipe of diameter is put, but because runoff water has the impulse force of horizontal direction, so that the equal outlet pipe of diameter
Water yield is not completely equivalent.Fourth, porous shunting, this is shunted with multitube, and some are similar, but unlike shunted with hole, sampling
Current still need to take over, and because hole is different with the resistance of pipe, thus the precision for shunting water is not high.Above-mentioned several part flow arrangements are mostly
Take brick to mix masonry way to implement, floor space is big, material labour cost is high, irremovable, precision is low, to different runoff waters
The bad adaptability of amount, soil loss monitoring and the monitoring of runoff field method are primarily used for, are not suitable for the method monitoring of runoff pond.In recent years
Come, some portable runoff observation devices and equipment also occur, but they typically have machinery, sensing, electric part, structure
Complexity is made, cost is higher, and must also configure power (power supply, fuel feeding etc.) could work.The portable runoff observation device that has or
Part flow arrangement in equipment is excessively simple or design is unreasonable, have impact on shunting precision, causes its practical value not high.
In summary, the problem of prior art is present be：Existing part flow arrangement mostly takes brick to mix masonry way implementation, accounts for
Ground area is big, material labour cost is high, irremovable, precision is low, different runoffs are come with the bad adaptability of water, and mainly uses
