A Debris Flow Impact Force Experimental System

Abstract

The invention discloses a mud flow impact force experiment system. The mud flow impact force experiment system comprises a slurry material box, a slurry material tank and an experimental instrument, wherein the slurry material box is arranged on the upstream of the slurry material tank; a collided block is arranged in the slurry material tank; a force sensor is arranged on the collided block; the experimental instrument adopts a simple pendulum structure, and mainly comprises a foot stool, a cross beam and a collision block, wherein the foot stool is used for supporting the cross beam above the slurry material tank; a driving motor is arranged on the cross beam; the output shaft of the driving motor is connected with a swinging rod; a dial scale used for detecting the swinging angle of the swinging rod is arranged on the cross beam; the collision block is connected to the other end of the swinging rod; the experimental instrument is supported above the collided block. According to the mud flow impact force experimental system, the impact force to the collided block caused by a slurry material is controlled by controlling the slurry material output speed of the slurry material box; the impact force of the collision block to the collided block is controlled through a simple pendulum principle of the experimental instrument; further, the interrelation between the impact force of the collision block to the collided block in the slurry material tank and the impact force of the slurry material in the slurry material tank to the collided block is explored.

Description

technical field [0001] The invention relates to a mud-rock flow impact force experiment system. Background technique [0002] In mountainous valleys, disasters caused by special floods that contain a large amount of solid debris such as mud, sand, stones, etc., and have strong impact and destructive effects, caused by heavy rain, a large amount of ice and snow melt water, or rapid surface runoff after the burst of rivers, lakes, and reservoirs. . Debris flow is a common natural disaster phenomenon in mountainous areas. It is a special fluid composed of loose solid materials such as sediment and stones and water. When it erupts, the valley roars, the ground vibrates, and the thick fluid surges and flows down the valley or slope, rushing to the outside of the mountain or the foot of the slope, often causing casualties and property losses in an instant. The physical model test research on the impact force of debris flow is still immature, and there is a lack of data support f...
