Abstract

The invention relates to the field of tests of anti-scouring performance of soil and vegetation, and discloses an in-situ test device for measuring the anti-scouring performance of soil and vegetation. The device comprises an annular test plate provided with an annular runner with an opened upper end. The annular test plate is in an annular shape. The annular runner comprises a driving runner section and an anti-scouring runner section. A power element, which is used to drive water flow to circularly move in the annular runner, is arranged in the driving runner section. A through groove is arranged on the bottom of the anti-scouring runner section. A Pitot tube for measuring the anti-scouring flow speed of soil and vegetation is arranged in the through groove. Compared with the prior art, the device has the advantages that the original soil and vegetation do not need to be sampled, transported, or preserved; the soil and vegetation can be arranged in the through groove in the bottom of the anti-scouring runner section of the annular runner, then the power element in the driving runner section drives water flow to circularly move in the annular runner, the Pitot tube in the through groove can measure the anti-scouring flow speed of soil and vegetation; the measurement is carried out on site, the sampling of original soil and vegetation is not needed, and the results of anti-souring flow speed are more accurate.

Description

technical field [0001] The invention relates to the field of testing the anti-shock ability of soil and vegetation, in particular to an in-situ test device for testing the anti-scour ability of soil and vegetation. Background technique [0002] Vegetation is an important barrier for soil and water conservation and slope stability and anti-scouring. [0003] The anti-scour capacity of soil and vegetation is the key indicator of river regulation, embankment protection, underwater tunnel, water and soil conservation and other projects. Generally, the process of water delivery or flood discharge in the river is accompanied by the scour of the river bed surface, which is easy to cause river bed erosion. Excessive scour depth or undercut phenomenon will affect the stability of hydraulic structures and embankment itself, especially in the project section where the tunnel passes through the river bottom. Excessive scour depth may even cause safety accidents in the operation of under...
