Целью изобретени вл етс улучшение эксплуатационных качеств лизиметра путем повышени точности измерени испарени при наличии поверхностного стока Лизиметр включает грунтовый монолит 2, металлический корпус 1 и поддон 3 с фильтрующим материалом, в котором расположены распределительные трубы 4, соединенные с трубой 5 и емкостью 6 дл сбора стока с поверхности монолита В корпусе лизиметра прорезана щель 8, через которую по приваренному к корпусу лизиметра с внешней стороны желобу 9 сток поступает в сливную трубу 10 и водосборную емкость, что позвол ет повысить точность измерени суммарного испарени и проводить водобалансовые исследовани с учетом поверхностного стока. 1 ил.The invention relates to land reclamation, namely, devices for studying the water balance of soil and ground. The aim of the invention is to improve the performance of a lysimeter by improving the measurement accuracy of evaporation in the presence of surface runoff. The lysimeter includes a ground monolith 2, a metal body 1 and a tray 3 with filter material, in which distribution pipes 4 are located, connected to pipe 5 and a tank 6 for collecting drain from the surface of the monolith In the case of the lysimeter, a slit 8 is cut, through which the drain 9 enters the drain pipe 10 and the catchment basin through the chute 9 welded to the case of the lysimeter from the outside bone, which allows to improve the accuracy of measurement of total evaporation and to conduct water balance studies taking into account surface runoff. 1 il.
Description
Изобретение относится к мелиорации, а именно к устройствам для исследования водного режима почвогрунтов.The invention relates to land reclamation, and in particular to devices for studying the water regime of soil.
Цель изобретения - улучшение зксплу- 5 атационных качеств лизиметра путем повышения точности измерения испарения при наличии поверхностного стока.The purpose of the invention is to improve the operational performance of the lysimeter by increasing the accuracy of measuring evaporation in the presence of surface runoff.
На чертеже показан лизиметр, общий вид в разрезе. 10The drawing shows a lysimeter, a General view in section. 10
Лизиметр содержит корпус 1, заполненный монолитом грунта 2, поверхность которого расположена под углом а. К корпусу 1 приварен поддон 3 с фильтрующим материалом, в котором расположены водораспре- 15 делительные трубы 4. Они соединены с наблюдательной трубой 5 для измерения величины водообмена зоны аэрации с грунтовыми водами. Для измерения поверхностного стока изготовлена емкость 6, 20 вставленная в корпус 7. В корпусе 1 прорезана щель 8, а ниже приварен желоб 9. который соединен с водосборной емкостью 6 соединительной трубой 10. В монолите грунта 2 пробурена скважина, в которую 25 вставлена дюралюминиевая труба 11 для измерения влажности почвы в зоне аэрации.The lysimeter contains a housing 1 filled with a monolith of soil 2, the surface of which is located at an angle a. A pan 3 with a filter material is welded to the housing 1, in which there are water distribution pipes 4. They are connected to the observation pipe 5 to measure the amount of water exchange in the aeration zone with groundwater. To measure the surface runoff, a container 6, 20 is inserted, inserted into the housing 7. A slot 8 is cut in the housing 1, and a trough 9 is welded below. It is connected to the drainage tank 6 by the connecting pipe 10. In the soil monolith 2, a well has been drilled, into which 25 an aluminum pipe is inserted 11 for measuring soil moisture in the aeration zone.
Лизиметр работает следующим образом. 30The lysimeter works as follows. thirty
От естественных осадков или поливов образуются поверхностный сток и инфильтрация влаги в грунтовые воды. Поверхностный сток от осадков через щель 8 попадает в желоб 9 и по соединительной трубе 10 попадает в водосборную емкость 6. Инфильтрационный поток влаги попадает в грунтовые воды, тем самым повышая их уровень. На заданном уровне грунтовые воды поддерживают методом откачки части воды из трубы 5. При интенсивном испарении уровень грунтовых вод понижается, на заданном уровне его поддерживают методом долива в трубу 5. Влажность почвы измеряют с помощью нейтронного влагомера ВПГР-1, для чего используется скважина, армированная дюралюминиевой трубой 11, и с учетом поверхностного стока определяют суммарное испарениеFrom natural rainfall or watering, surface runoff and moisture infiltration into groundwater are formed. The surface runoff from precipitation through the slot 8 enters the trench 9 and through the connecting pipe 10 enters the drainage tank 6. The infiltration moisture stream enters the groundwater, thereby increasing their level. At a given level, groundwater is maintained by pumping part of the water out of pipe 5. With intense evaporation, the groundwater level is lowered, and at a given level, it is maintained by adding to the pipe 5. Soil moisture is measured using a VPGR-1 neutron hydrometer, for which a well reinforced is used. duralumin pipe 11, and taking into account surface runoff determine the total evaporation
