A device for measuring soil saturated hydraulic conductivity, comprising a water supply tank (1), a water tank support (2), a connecting hose (3), a ring cutter sleeve (4), a ring cutter (5), an outlet water tank (6), Water measure (7). The water supply tank (1) is a rectangular box with a cover plate on the top and an outlet nozzle and an overflow nozzle on the bottom. The water tank support (2) is a long table, the table top is provided with an outlet hole and an overflow hole, two table legs are left with holes for fixing the water outlet water tank (4), and a level adjustment knob is arranged under the table foot. The nozzle of the connecting hose (3) is matched with the outlet of the water supply tank (1), the nozzle of the ring knife casing (4), and the inlet of the water outlet tank (6). The flexible pipe (3) and the ring knife (5) are connected at both ends of the ring knife casing (4). The water outlet tank (6) is equipped with a horn-shaped overflow port. Described water measuring device (7) is marked with scale, is connected with outlet water tank (6) overflow port. The instrument is simple in structure and widely applicable.
Description
technical field [0001] The invention relates to a soil parameter measuring device used in a laboratory, in particular to a soil saturated hydraulic conductivity measuring device. Background technique [0002] Soil saturated hydraulic conductivity is a very important parameter in the field of soil physics. Currently, the saturated hydraulic conductivity measuring instruments on the market are complex in structure and expensive in cost, which is not conducive to popularization. [0003] The methods for measuring soil saturated hydraulic conductivity include double-ring method, constant head method, variable head method, disc infiltration method, etc. The laboratory often uses the constant water head method and the variable water head method to measure the soil saturated hydraulic conductivity. The constant water head method is to measure the saturated hydraulic conductivity under steady state conditions. It is easy to operate and the result is intuitive, but it needs to keep...
