Abstract
The utility model discloses a test device for clay permeability coefficients. The test device for the clay permeability coefficients comprises a cylindrical vessel, wherein the upper end and the lower end of the cylindrical vessel are provided with permeable layers; the upper end of the cylindrical vessel is connected with a pressure device through a connecting pipe; the pressure device is provided with a pressure gauge; the lower end of the cylindrical vessel is connected with a flow vessel through a connecting pipe; and the connecting pipe which is connected with the flow vessel is provided with a flow control valve. The test device for the clay permeability coefficients has the advantages that: the defects of the conventional test are overcome, and the clay permeability coefficients can be accurately tested.
Description
Technical field
The utility model relates to a kind of proving installation, especially the clay pervasion coefficient testing device.
Background technology
The clay pervasion coefficient is the important parameter of decision aeration zone perviousness ability, also is the parameter of atmospheric precipitation recharge of phreatic water ability.The mensuration of conventional clay pervasion coefficient can be divided into field measuring and indoor measurement, because the clay hole is little, exists with the form of tie water, and the osmotic coefficient investigating time is long, and it is strong that existing proving installation is subject to perturbation, and perviousness can not reflect actual conditions.Therefore, be necessary to work out the determinator that can satisfy this two aspects requirement.
The utility model content
The technical matters that the utility model will solve provides a kind of clay pervasion coefficient testing device, and it is not enough to overcome existing test, and the clay pervasion coefficient is measured.
The utility model is realized through following technical scheme.
A kind of clay pervasion coefficient testing device; Comprise column shape container; Its upper and lower side is equipped with permeable layer, and the upper end of column shape container is through the external pressue device of connecting pipe, and pressue device is provided with tensimeter; The lower end of column shape container is through the external flow container of connecting pipe, and the connecting pipe of connection traffic container is provided with flowrate control valve.
Further, above-mentioned column shape container is that two sub-containers link together about inciting somebody to action through the flange at middle part.
Further, the permeable layer of above-mentioned column shape container upper end is a sandy gravel stratum, and the sandy gravel stratum lower end is provided with screen cloth.
Further, the permeable layer of above-mentioned column shape container lower end is a sandy gravel stratum, and the sandy gravel stratum upper end is provided with screen cloth.
The beneficial effect of the utility model is, to existing clay pervasion coefficient determination, length consuming time; And the defective that detouring property is big; Provide under a kind of different pressures condition, it is not enough to overcome existing test, the device that the clay pervasion coefficient is measured; Can accurately test out the infiltration coefficient of clay, easy and simple to handle.
Description of drawings
Fig. 1 is the structural representation of this case study on implementation clay pervasion coefficient testing device.
Embodiment
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of this case study on implementation clay pervasion coefficient testing device, with reference to Fig. 1, and the utility model, the clay pervasion coefficient testing device, it comprises column shape container 1, pressue device 2, flow container 3.
The upper end 111 of column shape container 1 connects pressue device 2 through connecting pipe 4, and pressue device 2 is provided with tensimeter 21.The lower end 131 of column shape container 1 is through connecting pipe 5 connection traffic containers 3, and connecting pipe 5 places are provided with flowrate control valve 51.
The utility model when the clay pervasion coefficient testing device uses, is gathered undisturbed soil sample with sampling thief in the open air; The column shape container 1 of packing into then, and, close flowrate control valve 51 with flange 15 connexon containers 11 and sub-containers 13; Observe tensimeter 21 and required pressure is set, after pressurization a period of time, open flowrate control valve 51 at pressue device 2; Write down the time and the aquifer yield in this stage through the water yield of 3 li in flow container; Repeat above-mentioned steps 2-3 time, test figure Darcy formula capable of using, calculation permeability coefficient.
To existing clay pervasion coefficient determination, length consuming time, and the big defective of detouring property; Provide under a kind of different pressures condition, it is not enough to overcome existing test, the device that the clay pervasion coefficient is measured; It is the utility model; The clay pervasion coefficient testing device can accurately test out the infiltration coefficient of clay, and is easy and simple to handle.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage that is familiar with this art can understand the utility model content and also implements, and can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the utility model.
