Soil infiltration capacity monitoring device and monitoring method

Abstract

The invention provides a soil infiltration capacity monitoring device and monitoring method. The monitoring device comprises a barrel body used for being inserted into arsenic sandstone area soil, a water injection mechanism used for injecting water into the barrel body and a monitoring mechanism used for monitoring the soil infiltration capacity. The water injection mechanism is arranged at the top of the barrel body, the water injection mechanism is communicated with the barrel body through a pipeline, and the monitoring mechanism is arranged at the bottom of the barrel body. By monitoring the soil moisture infiltration amount in the buried bottomless barrel, a saturated infiltration amount of the soil in an arsenic sandstone area is obtained, near-natural measurement of infiltration capacity and infiltration rate of the soil in the arsenic sandstone area is achieved, labor intensity of a user is reduced, and accuracy of experimental data is improved.

Description

technical field [0001] The invention relates to the technical field of natural monitoring experimental equipment, in particular to a soil infiltration capacity monitoring device and a monitoring method. Background technique [0002] The arsenic sandstone is known as the cancer of the earth. It turns into mud when it meets water, and its soil aggregation ability is poor. Moreover, the annual rainfall in the sandstone area is low, and most of the rainfall is heavy rain. After the rain, most of the water is lost in the form of runoff. Most of the long-term weak rainfall can provide soil infiltration and water demand for vegetation. Therefore, it has long been an urgent problem to be solved for the soil moisture infiltration measurement in the Pisha sandstone area in the field test. In the prior art, when collecting soil infiltration data in the field, a soil moisture meter or the like is mostly used. Although these instruments can effectively measure soil infiltration, they a...

Problems solved by technology

The former has extremely high requirements for instruments and requires high monitoring costs; the latter requires high field soil collection experience, and the collected soil samples need to be transported back to the laboratory as soon as possible, and multi-day sampling data requires standardized soil Preservation measures need to be measured immediately after being brought back to the laboratory. These steps can affect the accuracy of monitoring results
