Batch determinator for soil saturated water conductivity of automatic flow-control constant head with float ball and lever

Abstract

The invention relates to a batch determinator for soil saturated water conductivity of an automatic flow-control constant head with a float ball and a lever. The batch determinator is composed of a water supply device, a float lever device, a water determining device and a water receiving device, wherein the water supply device comprises a water supply tank, a water supply tank support and a water supply tank water outlet pipe; the float ball lever comprises the lever, the float ball, a piston and a piston connecting rod; the water determining device comprises a water determining tank, a cutting ring exposure opening, a rubber plug, a rubber sleave, a cutting ring and a cutting ring bottom cover; the water receiving device comprises a funnel stand, a funnel and a conical flask. The determinator can efficiently and precisely determine the soil saturated water conductivity, also can automatically add water, and ensures the determination condition of the constant head.

Description

technical field

[0001] The invention relates to a measuring instrument for measuring soil saturated hydraulic conductivity, in particular to a device capable of automatically adding water and measuring soil saturated hydraulic conductivity in batches by means of constant water head method. Background technique

[0002] Soil saturated hydraulic conductivity (also known as soil permeability coefficient or hydraulic conductivity coefficient) refers to the amount of water passing through a unit area per unit time under a unit water potential gradient when the soil is saturated with water. It is the characteristic of soil texture, bulk density and pore distribution. Function is one of the important physical properties of soil, which reflects the pore condition and water conductivity of the soil, as well as the soil texture. Soil saturated hydraulic conductivity can reflect the movement process of soil water in the field to a large extent, such as water infiltration, redistributio...
