Example Embodiment

[0026] With reference to the drawings, the present invention will be further explained:

[0027] The experimental device for unsteady debris flow includes a water storage tank 1, a hopper 2 containing soil and rock materials, a rack for placing the hopper, a tank 3 and a collection tank 4. The inlet 31 of the tank 3 is higher than the outlet 32, so The water outlet 11 of the water storage tank 1 is connected with the inlet 31 of the tank 3, and the water in the water storage tank 1 and the soil and rock materials in the hopper 2 merge at the inlet of the tank 3 to form an experimental use The debris flow fluid flows into the collecting pool 4 along the trough 3;

[0028] The bottom plate of the tank 3 is provided with a pressure sensor 5, and the side plate of the tank 3 is transparent.

[0029] The water inlet pipe 11 of the water storage tank 1 is provided with an electromagnetic flow meter 6, and the water inlet 11 of the water storage tank 1 is in the form of a cylindrical grid....

Abstract

The invention discloses an experimental apparatus for a non-constant debris flow. The experimental apparatus comprises a water storage tank, a hopper placed with debris, a frame for installing the hopper, a tank which is obliquely arranged and has an adjustable oblique angle, and an aggregate pool for accommodating the materials from the tank, wherein the inlet of the tank is higher than the outlet of the tank, the water outlet of the water storage tank is connected with the inlet of the tank, the water in the water storage tank and the debris in the hopper converge at the inlet of the tank to form the experimental debris flow fluid; then the debris flow fluid flows into the aggregate pool along the tank; and the bottom plate of the tank is provided with a pressure sensor, and the side plates of the tank are transparent. The invention has the advantages that: the experimental apparatus is simple in operation and can be used for effectively studying the movement characteristics of the non-constant debris flow.

Description

technical field [0001] The invention relates to a mud-rock flow experimental device, in particular to an experimental device for studying unsteady mud-rock flow. technical background [0002] my country is a mountainous country, and the mountainous area accounts for 70% of the country's land area. According to statistics, there are more than 8,500 debris flow ditches in my country, making it one of the countries in the world where debris flows are most developed, widely distributed, largest in number, and most harmful. The Tianshan Mountains, Qilian Mountains, the front mountains of the Kunlun Mountains, the Qinling Mountains, the Taihang Mountains, the Western Mountains of Beijing, western and northeastern Yunnan, and the mountainous areas of western Sichuan are typical areas where debris flows occur frequently and cause serious damage. For example, in the Xiaojiang River Basin in Northeast Yunnan, where the drainage area is only over 3,000 square kilometers, the total num...
