Rolling stone release device and test method for indoor test

Abstract

The invention discloses a rolling stone releasing apparatus for an indoor test and a rolling stone releasing test method. The rolling stone releasing apparatus comprises a bracket, a horizontal positioning device, a rolling stone releasing box, a sliding support plate, a height adjusting device, a rolling stone releasing device and a slope body; wherein the horizontal positioning device is fixed above the bracket for adjusting the horizontal position of a rolling stone releasing site; the sliding support plate is mounted above the horizontal positioning device, the height adjusting device and the rolling stone releasing device are mounted on the sliding support plate, the rolling stone releasing box is installed at the lower end of the height adjusting device and is used for adjusting the height of the rolling stone releasing box; one side the rolling stone releasing box is provided with an opening, the end, located at the opening, of the bottom plate of the rolling stone releasing box is fixed and the other positions of the bottom plate are free, a test piece is placed over the bottom plate, the lower end of the rolling stone releasing device is connected with the free end of the bottom plate, the rolling stone releasing device drives the bottom plate to rotate around the fixed end, and after the bottom plate is rotated to a set angle, the test piece falls to the slope body under the action of the gravity of the test piece.

Description

technical field [0001] The invention relates to a rolling stone release device and a test method for indoor tests. technical background [0002] With the rapid development of national construction, large-scale and super-large water conservancy and hydropower projects, transportation, municipal roads and tunnels and other projects built in mountainous areas are increasing day by day. There are a large number of dangerous rock masses and high and steep slopes in such places. The southwest mountainous area is one of the areas with the most serious geological disasters in my country. With the gradual implementation of my country's western development strategy, in order to speed up the development of the western region, the country's investment in infrastructure construction in the western region is also gradually increasing, among which roads and railways are more It is the top priority of construction. The geological disasters of dangerous rock instability and landslides have i...

Problems solved by technology

For indoor tests, there is currently no more efficient release device for rolling stones. The previous indoor test rolling stone release devices are relatively simple, mainly relying on manual operation, which is inefficient and lacks practicability.

In addition, the previous devices cannot realize the adjustment of the free release position of falling rocks in three-dimensional space, or the safety of the devices is poor, and safety accidents are prone to occur
