Abstract
The invention relates to an evaporation-preventing double-ring infiltrometer easy to mount and fix. The evaporation-preventing double-ring infiltrometer is composed of a water supply bottle, an inner ring, an outer ring, a fixing and connecting rod for connecting the inner ring and the outer ring, as well as a knocking cover board and an evaporation-preventing cover board which are mounted at the tops of the inner ring and the outer ring. All the components are independent, are convenient to carry, and are assembled after on-site tests. The inner ring and the outer ring are connected and fixed by the fixing and connecting rod, so that the integral rigidity of the inner ring and the outer ring is improved, and the bottoms of the double rings are prevented from entering soil to cause deflection. The knocking cover board is additionally arranged at the tops of the inner ring and the outer ring, when the inner ring and the outer ring are knocked, the inner ring and the outer ring stably enter the soil as a whole body, and can not warp up or incline. In addition, in the liquid permeation process, since the evaporation-preventing cover board is additionally mounted at the tops of the inner ring and the outer ring, so that great evaporation caused by weather is avoided. Therefore, the infiltration boundary conditions are strictly controlled while the infiltration capacity is accurately measured, so that the accurate infiltration rate of the soil is obtained, and the infiltration characteristics of the soil are mastered.
Description
Technical field
The present invention relates to a kind of infiltration instrument of on-site measurement soil body infiltration rate, particularly relate to a kind of being easy to and install and fixing vaporization prevention type double-ring infiltration instrument.
Background technology
Infiltrate and refer to that the moisture such as rainfall, irrigation enters the process of the soil body, be rainfall, an important step that surface water and groundwater transforms mutually.The soil body infiltrates with the soil erosion, Surface Runoff, field irrigation, that water brings out the problems such as geologic hazard is closely related.Therefore, it is most important that the understanding soil body infiltrates performance, the particularly infiltration character of the on-the-spot soil body.At present, the mensuration of on-the-spot soil body infiltration rate adopts monocycle or double-ring infiltration method more, and these test methods are not enough below possibility in process of the test:
1. in infiltration process, moisture level diffusion is not that one dimension infiltrates.In monocycle method infiltration process, moisture inevitably spreads to horizontal direction.Traditional double is around-France, and inner and outer rings is independent, is squeezed into by ring in the process of the soil body and cannot guarantee that inner and outer ring center is consistent, makes moisture level diffusion will occur in infiltration process, affects the Accurate Determining of infiltration rate.
2. the soil body and inner and outer rings may come in contact seepage flow.In time directly knocking inner and outer rings, the run-off the straight of ring wall possibility, can form gap when revising between ring wall and the soil body, will come in contact seepage flow, and affect the measuring accuracy of soil body infiltration rate in water infiltration process.
3. do not consider to evaporate the impact of measuring seepage discharge.In on-the-spot seepage tests process, because the liquid level area of inner and outer rings fixed level is comparatively large, the impact ignoring evaporation will cause the infiltration rate of gained bigger than normal.
4. infiltration capacity measuring accuracy is low.Tradition monocycle or dicyclo method adopt heavy caliber geneva bottle supply water or directly pour in ring by water, with this measure infiltrate moisture volumetric errors very greatly, the infiltration rate calculated and actual value deviation larger.
