Embodiment Construction

[0025] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0026] Such as Figure 1~4 As shown, a kind of infiltration simulation measurement device provided by the present invention includes a test cylinder 1, a water collection mechanism, a pressure sensor 12 and an FDR probe 13;

[0027] The top of the test column 1 is open, and the test column 1 is used to accommodate soil, and the bottom of the test column 1 is provided with a filter screen 4;

[0028] The filter screen 4 can be made of multi-layer asbestos net, permeable non-woven fabric or permeable stone material; the water permeability rate should not affect the infiltration rate of the upper soil column, while preventing the soil from flowing out in the column...

Abstract

The invention discloses a measurement device for infiltration simulation. The measurement device comprises a test cylinder, a water collecting mechanism, a pressure sensor and an FDR probe, wherein the test cylinder is used for accommodating soil; a filter mesh is arranged at the bottom of the test cylinder; circular holes are formed in a side wall of the test cylinder; the pressure sensor and theFDR probe are inserted in the test cylinder through the circular holes from the outer side and are used for detecting a water pressure and humidity; the water collecting mechanism comprises a water conveying pipe and an electromagnetic flowmeter; one end of the water conveying pipe is used for collecting liquid infiltrated to the bottom of the test cylinder; the electromagnetic flowmeter is connected to the water conveying pipe; the water collecting mechanism further comprises a funnel; and the funnel is arranged between the water conveying pipe and the test cylinder. When soil moisture infiltration simulation is performed, a soil infiltration coefficient can be quickly measured according to an existing relevant formula according to an instrument and existing parameters; and the measurement device changes single infiltration process simulation, can directly and effectively obtain test data, and solves problems of large error and difficulty in cleaning up.

Description

technical field [0001] The invention discloses an infiltration simulation measurement device, which relates to the field of geotechnical test devices. Background technique [0002] With the growth of population, the development of modern agriculture and tourism, the acceleration of industrialization and urbanization, and the improvement of ecological environment, the consumption of water resources continues to increase, and the shortage of water resources and soil water pollution have become the focus of attention. As the carrier of soil pollutants, soil water has received widespread attention in terms of rational utilization and seepage diffusion. In recent years, the problem of soil and water pollution has become increasingly serious, which has affected the cycle of the ecological circle. Studying the law of water movement in soil and exploring the law of surface water replenishing groundwater under rainfall or irrigation conditions can provide theoretical reference for s...
