Abstract
The utility model relates to an apparatus for measuring the infiltration amount and the infiltration rate of meteoric water in unit soil, comprising a drum-type filter. A water collecting funnel is arranged in the drum-type filter, the lower end of the water collecting funnel is connected with one end of a water outlet pipe, and the drum-type filter is led out from the other end of the water outlet pipe and is communicated with a water collector. The utility model has the advantages that, firstly, the problem of measuring the infiltration rate of rainfall in soil slopes such as earth dams, canal slopes, landslips and the like is solved, and the dynamics and infiltration characteristics of the soil body of the slopes can be conveniently and accurately mastered; secondly, the soil infiltration measuring apparatus is buried in the horizontal direction on the soil slops, the soil body at the upper part of the apparatus is not disturbed, thereby the measured data are real and reliable and have strong representativeness, the unit infiltration rate and the total infiltration rate of an engineering region can be effectively measured, and great convenience is brought for the soil engineering design, scientific research, operation management and safety monitoring; and thirdly, the utility model has simple structure, high measuring precision, reliable operation, convenient use, strong practicability and lower cost, and does not need frequent maintenance.
Description
Technical field
The utility model relates to a kind of device that is used to measure atmospheric precipitation pedological unit infiltration capacity and infiltration rate, this device mainly is applicable to Hydraulic and Hydro-Power Engineering, involved relevant monitoring of soil-slope precipitation infiltration and the scientific experimentation project such as earth dam, Qu Po, sliding mass and water and soil conservation in Geotechnical Engineering field, also can be applicable to other field monitoring project relevant with the soil-slope precipitation infiltration.
Background technology
The works such as soil property dam, canal (dike) slope, sliding mass and high slope that Geotechnical Engineering is involved, its stability and safety and atmospheric precipitation, phreatic variation, soil body water cut etc. are in close relations, when landslide o earth slope body or slope underground water position or water cut surpass design conditions, very likely cause landslide accident, the lighter influences traffic and duration, and weight person causes casualties.Thereby when the design soil-slope, must understand the soil infiltration situation.Main at present employing dual mode is measured: 1, trench drain and rain gage are set on sliding mass or side slope, record this zone gross precipitation and total displacement, both differences are the total infiltration capacity of side slope; 2, vertically bury piezometric tube underground, record the variation of underground water table to pore-creating.Above first method can only be measured from macroscopic view, and error is bigger; Second method can only be measured WATER LEVEL CHANGES, and soil infiltration rate is not understood substantially.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of soil body infiltration capacity of measured soil surface when precipitation and soil infiltration analyzer of soil body infiltration rate of being used for, not only usability is reliable, measuring accuracy is high for it, practical, and simple in structure, implement convenient.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution is taked is: include core strainer, be installed on the funnel that catchments in the core strainer, the funnel lower end of catchmenting connects rising pipe, and the rising pipe other end is drawn core strainer and is connected with water collector.
Press such scheme, described core strainer includes cylindrical shell, and the upper surface of cylindrical shell is provided with screen cloth or sieve plate, and the outside earthing worker nonwoven fabric layer of screen cloth or sieve plate is installed in the cylindrical shell and the allo funnel that catchments of cylinder inboard wall.
Press such scheme, offer aperture in the middle and upper part of the funnel that catchments and connect snorkel.
Press such scheme, described water collector is a collection bottle, and the bottle that catchments is marked with the volume scale; The bottle that catchments sealing, the upper end connects rising pipe and gas outlet.
When the utility model uses, bury underground to drawing the hole in soil-slope position level, core strainer is positioned at the hole, and bottom face is risen with hard thing pad, and top geotextile layer is closely contacted with the top soil body.Rising pipe and snorkel are drawn outside the hole, be backfilled to the hole, again collection bottle is installed on the bottom, hole with original soil.When survey side slope position occurred continuing precipitation, after last overburden layer suction was saturated, the unnecessary water yield was infiltrated in funnel by geotextile and filter screen, and the rising pipe by linking to each other with funnel, finally is pooled to the collection bottle that is arranged in the below, hole.The water yield of collecting can directly read by the scale on the collection bottle, also can pour in the measuring cup and accurately measure.By the water yield of collecting,, can calculate slope soil unit's infiltration rate and total infiltration rate in conjunction with raininess.
The beneficial effects of the utility model are: 1, solved the problems of measurement of the rainfall infiltration rate of soil-slopes such as earth dam, Qu Po, sliding mass, be convenient to accurately grasp and understand mechanics, the seepage characteristic of slope soil; 2, owing to level on slight slope is buried underground to drawing the hole, the instrument top soil body is undisturbed, the data of surveying true and reliable, representative strong, can effectively measure engineering area unit infiltration rate and total infiltration rate, bring great convenience for geotechnological design, scientific research, operational management, safety monitoring; 3, the utility model is simple in structure, the measuring accuracy height, and reliable, easy to use, practical, cost is lower, and need not often to keep in repair and maintain.
