The invention relates to the field of soil and vegetation scour resistance testing, and discloses an in-situ test device for testing soil and vegetation scour resistance, comprising a flow channel, the flow channel including a driving section and a test section, and a flow pusher is arranged in the driving section , the bottom of the test section is provided with a test channel for soil and vegetation to be exposed. Along the flow direction of the water flow in the test section, the bottom of the test section has a front bottom section and a rear bottom section. The front bottom section is inclined downward, and the rear bottom section The section is provided with a plurality of bosses, and the plurality of bosses are arranged at intervals along the length direction of the test section, and the bosses are higher than the test through groove; the through groove is provided with a pit tube; the in-situ test device can be directly placed on site Field test to achieve the effect of in situ test, no need to sample undisturbed soil and vegetation, and the sample does not need to go through the process of transportation and storage, and the front bottom section and the rear bottom section can truly simulate the flow impact of water flow, improving the test accuracy.
Description
technical field [0001] The invention relates to the technical field of in-situ test devices, in particular to an in-situ test device for testing the anti-scour ability of soil and vegetation. Background technique [0002] Soil and vegetation are important barriers for soil and water conservation to stabilize the bank slope and prevent scour. Therefore, the scour resistance of soil and vegetation is the key indicator for river regulation, embankment protection, underwater tunnels, and soil and water conservation projects. [0003] In the actual situation, the water conveying process of the river is accompanied by the scouring of the channel bed, so the flowing water will cause the river bed to dig deep or undercut, which will affect the stability of the hydraulic structures and the embankment itself. In the tunnel section through which the river bottom passes, the excessive scour depth of the flowing water may cause safety accidents in the operation of the underwater tunnel s...
