Soil erosion model device on variable width slope based on adaptive horizontal walkway

Abstract

The invention discloses a variable-width slope soil erosion model device based on an adaptive horizontal walkway, which includes a model bottom frame, on which a groove bottom steel plate and a rain shelter are arranged, and the model bottom frame is inclined Setting, the two sides of the bottom frame of the model are provided with pedals, pedal fixed plates, pedal sleeves, and pedal movable plates. The present invention overcomes the drawbacks of repeated construction of unnecessary models for model tests in the past, saves test costs, and the design of automatically maintaining the level of the walkway solves the shortcomings of the walkways on both sides of the test soil tank rising with the rise of the model, and automatically opens and closes the rain shelter It solves the shortcoming of manual time-consuming and labor-intensive covering of the slope before the test rainfall, and the installation of the reduced-area collector and the collection pipe of the soil flow innovatively solves the problems that have not been well solved in previous tests.

Description

technical field [0001] The invention relates to a slope soil erosion model with variable width and variable slope. The walkway of the soil erosion model can always keep a horizontal state with the rise and fall of the slope. The upper part of the model has an automatic opening and closing rain shelter to prevent The slope surface filled with model sand will be washed away when the rainfall is constant. At the same time, there is a soil mid-flow collection pipe at the outlet of the model. At the same time, the collecting port is narrower and smaller than that of the previous model, avoiding the In previous experiments, the rainfall on the larger area of ​​the catchment has an effect on the runoff of the entire slope. Background technique [0002] At present, although some of the slope erosion test models can adjust the slope, there is no model that can adjust the slope width. With the gradual maturity of simulation technology and the increasingly complex requirements of scien...

AI Technical Summary

Problems solved by technology

[0002] At present, although some of the slope erosion test models can adjust the slope, there is no model that can adjust the slope width. With the gradual maturity of simulation technology and the increasingly complex requirements of scientific research, many researches now need to be changed. The width of the slope model can be used to analyze the impact of slopes with different widths on the runoff and sediment production on the slope, which urgently requires that the width of the model can be changed to meet the needs of the research

At the same time, the slope model is often required to be able to adjust the slope. This technology is mature, and the slope can be adjusted by installing a hydraulic lifting system at the bottom of the model; at the same time, the research requires that the aisle on the slope can always be kept level with the adjustment of the slope. In the research, after the filling of the slope model is completed, it is necessary to calibrate whether the rain intensity of the rainfall device meets the requirements, but the rainfall is easy to damage the slope, and in order to prevent the slope from being destroyed, it must be used Covering with plastic sheeting, but the current method of manually covering the slope with plastic sheeting is very time-consuming and troublesome. A covering system that can automatically open and close is needed, which can automatically close the slope when the rain is determined before the test begins. Fully covered, can be opened when it rains without affecting the rainfall
