Description

В ОСНОВНОМ авт. св. Л 87669 описано устройство прибора дл  исследовани  воздушного режима пористых почв, в котором, с целью производства исследований воздушного режима пористых почв как в лабораторных, так и в полевых услови х при гидравлическом давлении выше атмосферного, заполнение испытуемого образца заданным объемом воздуха осушествл ют через мерную трубку, гидравлически св занную с манометрической трубкой, в процессе исследовани  перекрываемой запорным краном.BASIC Auth. St. L 87669 describes a device for investigating the air regime of porous soils, in which, for the purpose of conducting studies of the air regime of porous soils both in laboratory and field conditions at a hydraulic pressure above atmospheric, the test sample is filled with a specified volume of air through a measuring tube hydraulically connected to the manometric tube, in the process of investigation, blocked by a stopcock.

С целью исследовани  пористости и других показателей почвенных образцов в пределах колебаний атмосферного давлени  и предупреждени  возможной неточности показаний за счет разницы уровней жидкости в сообшаюш,ихс  трубках , манометрическа  трубка отсоединена от мерной и гидравлически соединена с параллельной контрольной трубкой, сообшаемой патрубком с камерой дл  исследуемого образца.In order to investigate porosity and other indicators of soil samples within atmospheric pressure fluctuations and prevent possible inaccuracy of readings due to the difference in fluid levels in the tubes, the manometric tube is disconnected from the gauge and hydraulically connected to the parallel control tube communicated with the chamber nozzle for the sample under study. .

Предлагаемый прибор дл  исследовани  водно-воздушного режима образцов пористых почв отличаетс  от известных тем, что дл  обеспечени  термодинамической уравновешенности прибора в нем применен изготовленный нз одинакового с камерой материала резервуар с негигроскопическим поглотителем. Дл  повышени  точности показаний прибора и возможности применени  его при повышенных степен х разр жени  вместо резиновых баллонов применено шприцевое устройство с макрорегулированием .The proposed device for studying the water-air regime of samples of porous soils differs from those known in that in order to ensure the thermodynamic balance of the device, it uses a tank with a non-hygroscopic absorber, which is identical with the camera material. To increase the accuracy of the instrument readings and the possibility of using it at elevated degrees of discharge, a syringe device with macro regulation was used instead of rubber cylinders.

Предлагаемый прибор применим дл  определени  аэрации, скважности , влажности, объемного веса сухой почвы и степени насыщенности почвы водой в полевых услови х .The proposed instrument is applicable for determining aeration, porosity, humidity, volumetric weight of dry soil and the degree of soil saturation with water in field conditions.
