Description

TECHNICAL FIELD

[0001] The utility model relates to soil permeation measurement technical field, concretely is a kind of soil permeation measurement device. BACKGROUND

[0002] Soil permeability is also called "soil water permeability", that is, the permeability of soil to surface water. It is one of the main properties affecting soil erosion, which is determined by factors such as soil texture, structure, porosity, humidity, profile configuration, etc. Generally, the soil with coarser texture, better structure, larger porosity and lower humidity is easier to permeate water, has larger water permeability, and reduces surface runoff. Conversely, the soil with slower permeation and smaller water permeability increases surface runoff, which enhances the erosion of soil.

[0003] In the Chinese patent with publication number CN220170811U, a soil permeation measurement device is disclosed. It can be quickly assembled by manually holding the handle fixedly connected to the front end of the bearing seat and inserting the sliding blocks fixedly connected to the left and right sides of the bearing seat into the longitudinal slots in the two side plates fixedly connected to the top end of the base. When the bearing seat is assembled above the base, the liquid permeation hole in the bearing seat needs to be aligned with the liquid permeation hole in the base, and then normal permeability detection can be performed to achieve a more practical purpose.

[0004] In the above-mentioned scheme, the soil permeation measurement is achieved by draining water from the bottom end of the test tube resting on the soil in the bearing seat. However, since the test tube has a small diameter, the water droplets falling from the test tube need to fill the soil surface before permeating, which causes a certain deviation in the measured data and reduces the measurement accuracy. Therefore, we provide a soil permeation measurement device to solve the above problems. UTILITY MODEL CONTENTS
