Description
Technical field
The utility model belongs to soil infiltration field, is measured more particularly to a kind of initial infiltration rate of soil portable
Device.
Background technology
Infiltrate be soil basic physical behavior, soil closely related with the processes such as Rainfall-runoff, erosion, non-point pollution
Earth Infiltration characteristics forecast flood forecasting and soil erosion prediction, and have to formulation water-and-soil conservation measures highly important
Reference role, quick, Accurate Determining soil infiltration rate have great importance.In addition, moisture can be with soil in infiltration process
Physical-chemical reaction occurs for earth particle, to change soil aperture feature and chemical composition, and then influences the infiltration character of soil；
Therefore, the basic Infiltration characteristics of soil are all the object of scientific research concern all the time, and about the research of Infiltration Characteristics,
It focuses mostly in research vegetation restoration rate, and actually the initial infiltration rate of soil can reflect the initial of soil well
Situation, the initial infiltration rate of soil and soil bulk density, powder mass fraction, field capacity and quality of organic matter score etc.
It is closely related.
Conventional soil, which infiltrates research method mainly, bicyclic, monocycle, disc permeameter, Hood infiltration instruments etc., various researchs
Method respectively has advantage and disadvantage.Bicyclic/monocycle iron hoop operation principle is pressed into infiltration grease head highness control to have, its main feature is that：When burying easily
Table soil is destroyed, experiment originates rapid plus water destructible table soil structure；Laborious water wasting, field operation are inconvenient, when laboratory fees, surely ooze about
Need 100min；Error in reading is larger, especially the starting stage, and data point is more unstable；Vertical Infiltration, it is bicyclic can anti-side ooze, monocycle
Slightly side is oozed outside ring；It is big representative strong to infiltrate depth, area.
Disc permeameter operation principle be infiltrate hydraulic pressure it is adjustable can negative-pressure infiltration, its main feature is that：This method laboratory apparatus is light
Just, water-saving is laborsaving, is convenient for field trial；More time saving, general 30min can surely ooze；Table soil is not disturbed, needs grain size < 0.25mm's
Dry sand；Read it is relatively accurate, especially can be compared with the initial infiltration process of Accurate Determining；It is poor to infiltrate the small representativeness of the depth, area, there is survey
Stream.
Hood infiltration instrument operation principles are negative-pressure infiltration, its main feature is that：Lighter and water-saving can add water pressure regulation at any time；Compared with
It is time saving, it surely oozes the period, but pressure regulation is complicated；Table soil is not disturbed, needs the saturation wet sand of grain size < 0.5mm；It is accurate that reading is compared,
But almost without process data；It is poor to infiltrate the small representativeness of the depth, area；Flow measurement is larger.
In traditional monocycle experimentation, with Markov bottle plus water because amount of water demand is larger so bad control Specific amounts, and
Error in reading is larger.
Traditional monocycle tests laborious water wasting, and field operation is inconvenient, and whens laboratory fees is longer, and error in reading is larger, especially initially
Stage, data point are more unstable.
Invention content
The purpose of this utility model is to provide the mancarried device that a kind of initial infiltration rate of soil measures, the device is logical
It crosses improvement tradition and infiltrates experimental determination device, not only save material, more can conveniently and efficiently apply to measure soil in practice
It is perfect to play supplement to soil infiltration scientific research for the initial infiltration rate of earth.
The purpose of this utility model and its technical problem underlying is solved using following technical scheme to realize：It is a kind of
The mancarried device that the initial infiltration rate of soil measures, including cutting ring, cutting ring pass through water-supply-pipe and transparent cylinder with a scale
The column that is filled with water connects, and the side that water-supply-pipe connect with cutting ring is the screw thread silk interface with control valve, water-supply-pipe and transparent with a scale
Cylinder be filled with water column connection side be screw thread silk interface.
The cutting ring is cast cutting ring, diameter 5cm, high 10cm.
The utility model basic functional principle：Experiment start plus water after, under the water oozed can be shown at scale, at scale
Scale use mm for unit, divided by the corresponding time can be obtained by initial infiltration rate.
The utility model advantageous effect：
The mineral water of one bottle of 500ml can measure the soil initial infiltration rate of multiple sampling points, few with water, and cooperation stopwatch is direct
The value of soil initial infiltration rate is read, is suitable for most area soil initial infiltration rate and measures, be particularly suitable for Karst Area
Crack soil initial infiltration rate measures.

The cutting ring 1 is cast cutting ring, diameter 5cm, high 10cm.
In use, by both sides, cutting ring 1 and transparent with a scale 5 cylinder are filled with water by the water-supply-pipe 3 with tap first
Column 6 connects, and at this moment control valve is closed；Then cutting ring 1 is slowly equably squeezed into 5cm in soil horizon 7 as possible,
Soil texture is kept not to be damaged as possible；Next mineral water bottle 10 is filled into water, the adjustment of stopwatch 9 is zeroed, then slowly by water
It injects transparent with a scale 5 cylinder and is filled with water column 6 until the water surface rises to the graduation mark that water column 6 maintains an equal level with cutting ring 1, then
Control valve valve is opened, while pressing stopwatch 9, the water that at this moment transparent with a scale 5 cylinder is filled with water in column 6 can slowly pass through defeated
Water pipe 3 flows into cutting ring 1, and then gradually oozes soil surface 8 down, when time to the experimental design time, while pressing 9 He of second hand stop table
Then closing control valve valve reads transparent with a scale 5 cylinder and is filled with water level scale number in column 6, according to front and back scale value
The difference of water level decreasing can be obtained, is then removed in the time with declining water-head value, the initial of experimental field soil can be obtained
Infiltration rate.The utility model infiltrates experimental determination device by improving tradition, not only saves material, more can be conveniently and efficiently
Apply in practice measure the initial infiltration rate of soil, it is perfect to play supplement to soil infiltration scientific research.
