Problems solved by technology

Through the test, the disadvantage is that if the soil box is filled with soil, due to the large amount of soil and the support point in the front, it will be more laborious to pull the pulley, and it is not convenient to use support rods and stoppers on both sides of the rear end of the runoff trough. , and cannot continuously change the slope

Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] Such as Figure 1-9 As shown, the three-dimensional simulation monitoring runoff test trough of variable-slope soil flow includes a base 1, on which the front movable support rod 2, the fixed support rod 3 of the runoff groove, the spiral support rod 6 for adjusting the slope, and the front movable support rod 2 are arranged in sequence. 1. Two runoff grooves 5 are arranged side by side on the fixed support rod 3 of the runoff groove and the spiral support rod 6 for adjusting the slope. The base 1 is provided with a roller track 12 and a side chute 11 cooperating with the front movable support bar 2, and the rear end of the base 1 is provided with a hollow beam 9 at the back of the base cooperating with the spiral support bar 6 for adjusting the gradient.

[0033] The runoff tank 5 is a multi-layer flow monitoring runoff tank. The front end of each layer of the tank...

Abstract

The invention discloses a slope-varying type interflow three-dimensional simulation monitoring runoff test flume. The runoff test flume comprises a base, wherein a front movable support rod, a runoff groove fixing support rod and a slope adjusting spiral support rod are sequentially arranged on the base, and a group of runoff grooves are formed in the front movable support rod, the runoff groove fixing support rod and the slope adjusting spiral support rod. The slope-varying type interflow three-dimensional simulation monitoring runoff test flume can monitor the flow velocity of interflows in different depths and also can monitor the flow of the interflows in different depths. Flow velocity monitoring holes in the lateral sides of the runoff grooves and flow monitoring outlets in the front ends of the runoff grooves can monitor the reaching position of a trace agent which is thrown into the interflow from a trace agent pipe along with the interflow, so that the flow velocity and the flow of the interflow can be calculated out. Thus, three-dimensional monitoring on the interflow can be achieved.

Description

technical field [0001] The invention belongs to the technical field of soil hydrodynamics, slope hydrology, water and soil conservation and agricultural non-point source pollution prevention and control simulation monitoring test device technical field, and specifically relates to a slope-changing three-dimensional simulation monitoring runoff test tank for mid-flow in soil. Background technique [0002] Under the background of increasingly serious soil pollution and groundwater pollution, studying the dynamic migration of soil pollutants with precipitation infiltration, the process of carrying them into surface water bodies with slope runoff, and the relationship between soil pollutants and groundwater pollution is currently an important issue in environmental geosciences. Research focus and hotspots. However, due to the uncontrollability of natural precipitation, the experimental research method under the control of indoor artificial simulated rainfall has always been the ...
