Description

Изобретепие может быть использовано в сельском и лесном хоз йствах.Invention can be used in rural and forestry households.

Известное устройство дл  определени  водопроницаемости талой почвы, включающее внешнюю (водозащитную) и внутреннюю (учетную) рамы, не пременимо дл  определени  водопроницаемости мерзлой почвы.The known device for determining the permeability of thawed soil, including external (water-proof) and internal (accounting) frames, is not suitable for determining the water permeability of frozen soil.

Цель изобретени  разработка устройства дл  определени  водопроницаемости мерзлой почвы достигаетс  тем, что внешн   рама выполнена в виде пустотелого двустенного направител , пристенной зазор которого заполн ют в зким незамерзающим веществом (например солидолом).The purpose of the invention to develop a device for determining the permeability of frozen soil is achieved by the fact that the outer frame is made in the form of a hollow double-walled guide, the wall gap of which is filled with a viscous non-freezing substance (for example, solid oil).

На чертеже схематично изображено предлагаемое устройство в двух проекци х.The drawing schematically shows the proposed device in two projections.

Устройство содержит направитель 1 с пристенным зазором 2, помещенным в почву 3, а учетна  рама 4 установлена в пристенный зазор. Нанравитель 1 снабжен крышкой 5. The device contains the sender 1 with a wall gap 2 placed in the soil 3, and the account frame 4 is installed in the wall gap. The nungater 1 is provided with a lid 5.

Определение водопроницаемости с помощью данного устройства осуществл ют следующим образом.The determination of water permeability using this device is as follows.

Осенью в талую почву устанавливают направитель на уровне дневной поверхности In the autumn, the guide should be set in the thawed soil at the surface

почвы или на 2-3 см ниже ее, пристенный зазор направител  заполн ют солидолом и закрывают крыщкой. Непосредственно перед определением водопроницаемости (ранней весной, после та ни  снега) в пристенный зазор направител  вставл ют внутреннюю раму, предварительно сн в крышку. Учетную раму заполн ют водой и наблюдают за ее расходом при фильтрации в почву.soil or 2-3 cm below it, the guide gap in the wall is filled with grease and covered with a lid. Immediately before determining the water permeability (in early spring, after snowing this way) a guide frame is inserted into the wall gap of the guide, which has been previously removed into the cover. The reference frame is filled with water and its consumption is monitored when it is filtered into the soil.
