Large-sized earth pillar series connection simulator for soil solute transport

Abstract

The invention relates to a large-sized earth pillar series connection simulator for soil solute transport, which belongs to the field of hydraulic engineering and has an IPC international patent classification code of E02B 1 / 100, E02D 33 / 00. The large-sized earth pillar series connection simulator comprises a water supplying system, simulated earth pillars, a sampling system, a series connection device, a draining system, and a data acquiring and control device, wherein the water supplying system comprises a water supplying peristaltic pump and a water supplying tube; the simulated earth pillars comprise a plurality of large-sized earth pillars; the sampling system comprises a water sampling port, a sampling tube, a sampling pump and a sampling container; the series connection device comprises series connection pressurizing water supplying equipment and a water supply tube which is connected with the large-sized earth pillars in series, and the series connection pressurizing water supplying equipment is preferably the peristaltic pump; the draining system comprises an electromagnetic valve and a draining tube; and the data acquiring and control device comprises a cable, a soil water sensor, a data acquisition controller and a computer. The simulator is suitable for the simulated research on the transportation of the solute in the large-sized soil profile and the simulator has the advantages of higher simulation precision, lesser investment and easier construction.

Description

1. Technical field

[0001] The invention relates to a large-scale serial simulation device for soil solute migration, which belongs to the field of water conservancy engineering, and its IPC international patent classification numbers are E02B 1 / 00 ​​and E02D 33 / 00. 2. Background technology

[0002] Soil solutes are the solutes in the soil solution. Soil solute transport studies the process, law and mechanism of solutes in the soil. At present, the study of soil solute transport has become an important part of soil science, ecology, water resources and resources and environment. The basic and cutting-edge research fields of science and other related disciplines are getting more and more attention. Indoor soil column simulation is an important means to study soil solute transport. The soil column simulation device for soil solute transport is an important device for indoor soil solute research. The domestic soil solute transport simulation device is generally made of circular...
