Description
Technical field
The utility model belongs to soil physical property analyzer technical field, more particularly to a kind of based on simple under core cutter method
Type soil soil hydraulic conductivity analyzer.
Background technique
Soil hydraulic conductivity is an important parameter for reflecting soil permeability.Soil hydraulic conductivity refers to unit water potential gradient
Under, it is the difficulty or ease journey measuring water and moving in the soil by the water velocity of the unit soil sectional area perpendicular to water (flow) direction
The infiltration coefficient of degree, it and soil is positively correlated.Soil hydraulic conductivity is the important ginseng for determining precipitation infiltration and runoff ratio
Number, and the soil water-solute migration and crop growth model, calculating soil profile water flux and design are irrigated, drainage system work
One important soil parameter of journey.The device of existing measurement soil derivative rate is excessively cumbersome, expensive, is not suitable for large-scale
Teaching and production practices application.
Summary of the invention
In view of the problems of the existing technology, the purpose of the utility model is to provide one kind based on simple type soil under core cutter method
Earth hydraulic conductivity analyzer, it is intended to solve the problems such as expensive present in existing instrument, complicated for operation.The device has knot
Structure is simple, low cost, easy to assembly, quick advantage, can guarantee the efficient performance of soil water hydraulic conductivity measurement.On reaching
Purpose is stated, the utility model uses following technical proposal.
One kind based on simple type soil hydraulic conductivity analyzer under core cutter method, including iron plate, iron, iron hoop, funnel, beaker,
Metal mesh, lower cutting ring and upper cutting ring.One end of the iron is fixed on the center of iron plate, and one end of iron hoop is equipped with movable fixing clamp
It is fixed with iron, funnel is provided in iron hoop, funnel has beaker, metal mesh is equipped with above funnel, is successively set on metal mesh
There are lower cutting ring and upper cutting ring.
Further, the funnel is fixed in iron hoop, connect funnel with iron hoop integral, it is ensured that lower cutting ring and upper ring
Knife is not fallen out.
Further, the metal mesh is worked out with diameter 1mm iron wire warp-weft two-way, and the gap between iron wire is 1mm, existing
Leakiness is not native again for hardness.
Further, the interface of the lower cutting ring and upper cutting ring seam can be sealed and be sealed with wax with insulating tape, be in lower cutting ring
Original state soil to be measured, upper cutting ring is to be filled with water.
When operation, take soil sample to be measured with lower cutting ring first, make soil sample water suction saturation, then take one it is identical as lower cutting ring diameter
Cutting ring as upper cutting ring, upper and lower cutting ring is sealed without after the gap suitable for reading alignment of sword with insulating tape, again along adhesive tape later
It seals with wax；Then cutting ring is put on metal mesh, gets out stopwatch, is slowly filled the water in upward cutting ring, water filling while pays attention to observing
Mouth under funnel starts to clock when first, which drips, falls into beaker, later every 1,2,3,5,10,20,30,40,50,60,70,
80,90,100min changes a beaker, and measures the water in beaker, after water starts leakage will in time up in cutting ring plus water,
Keep water layer thickness constant.After water wait leak out is stablized, seepage velocity and infiltration coefficient can be calculated from the formula.
The utility model has the beneficial effects that (1) the utility model is combined into simple type soil using the customary furnishings in laboratory
Earth hydraulic conductivity analyzer, and assembling process is convenient, operation is simple, has saved manpower and material resources, has been suitable for laboratory and field measurement
Soil hydraulic conductivity operation；(2) the utility model structure simple, intuitive, easy disassembly are easy to popularize, for classroom instruction and
Production practices have great help.
