Experimental device for roughness and erosion quantity of slope surface and using method of experimental device

Abstract

The invention discloses an experimental device for roughness and an erosion quantity of a slope surface and a using method of the experimental device. The experimental device is characterized by comprising a water supplier, a connection hose, an overflow box, a water isolation plate and a water collecting tank, wherein a water filling port with a piston A and an air exhaust pipe B are arranged above the water supplier; a water outlet valve C is arranged on the side wall of the bottom of the water supplier; a valve D is arranged at the bottom of the overflow box; a flow guide plate E is arranged on one side below the overflow box; a valve F is arranged at the bottom of the water collecting tank; a flow guide plate G is arranged above the water collecting tank; the valve C of the water supplier is connected with the valve D of the overflow box through the connection hose; and the flow guide plate E of the overflow box is connected with the flow guide plate G of the water collecting tank through the water isolation plate. The water collecting tank is used for collecting water from a measurement region, and the water is guided into a measurement cylinder through the valve F at the bottom of the water collecting tank, so that the flow-out water amount within unit time can be measured. The experimental device can be used for measuring the roughness and erosion quantity of slope surfaces under various outdoor topographic conditions and evaluating the impact resistance of the slope surface; and the device is easy to use and convenient to mount and carry.

Description

technical field [0001] The invention relates to an experimental device for measuring slope surface roughness and scouring amount in the field and a using method thereof. Background technique [0002] Slope roughness is a key parameter for calculating slope water flow velocity, and it is also a key parameter for establishing a slope soil erosion model. Therefore, roughness is of great significance for the study of slope soil erosion and slope runoff erosivity. But at present there is no special instrument for field measurement of slope surface roughness, and most of the slope scour tests are carried out in laboratories, and there are few introductions of portable instruments for field measurement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an experimental device for slope surface roughness and scouring volume and its use method, which can be applied to measure slope surface roughness and scouring volume under...
