An indoor soil infiltration rate measurement device and method

Abstract

The invention relates to an indoor soil infiltration rate measuring device and method, and is used for solving the problem that the measurement of the soil infiltration rate is relatively large in error in the prior art. The indoor soil infiltration rate measuring device comprises a fixed water head water supply device, a cutting ring, a filter net, a water collection and measurement device, an iron stand, a water storage vessel and a timing device; a water supply opening of the fixed water head water supply device is tightly combined with the upper part of the cutting ring; the cutting ring is used for placing a soil sample; the filter net is arranged at the bottom of the cutting ring and tightly contacts the bottom surface of the cutting ring, and the filter net is used for preventing soil from dropping into the water collection device in the water infiltration process; the water collection and measurement device is arranged at the lower part of the filter net and used for measuring the soil infiltration amount; the iron stand is arranged at the bottom of the water collection and measurement device and used for fixing the fixed water head water supply device, the cutting ring and the filter net; the water storage vessel is used for receiving water discharged by the fixed water head water supply device; the timing device is used for judging the soil infiltration moment and the moment when the soil reaches the steady infiltration.

Description

technical field [0001] The invention relates to the technical field of soil water balance and soil and water conservation observation, in particular to an indoor soil infiltration rate measuring device and method. Background technique [0002] Infiltration is a basic physical property of soil, which is closely related to rainfall runoff, soil erosion, and non-point source pollution. As an important parameter, soil infiltration rate plays a decisive role in flood forecasting, soil erosion forecasting and formulation of related soil and water conservation measures in local areas. Therefore, it is of great significance to quickly and accurately measure soil infiltration rate. [0003] At present, the constant water head method is often used indoors to measure the infiltration rate of soil. When the infiltration rate of the soil remains unchanged, it is considered that the steady infiltration state has been reached, and the infiltration rate at this time is the steady infiltrat...
