Benefits of technology

This patented system measures how well liquid enters underground during construction or other activities that may cause damage such as leakage into groundwater storage tanks. By monitoring this process it helps prevent accidents caused by excessive rain falling on property surfaces without causing significant damages.

Problems solved by technology

This patents describes two methods commonly known ways to estimate how well groundwater flows or contaminants penetrate into porous materials like clay mineral deposits (clays). These techniques involve collecting samples on top of a layered material called sandwich paper where they were tested under different conditions such as temperature, pressure, moisture content, etc., allowing them to be observed over longer periods without losing their integrity due to evaporation. By comparing these measurements against previous results obtained by other means, researchers have found potential sources of error during analysis.

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.
