Problems solved by technology

[0002] Among the existing test devices, there are relatively few test devices and equipment related to the impact of water flow erosion and water level rise and fall on the rock mass in the ebb zone, especially when considering various common natural conditions including sunshine, rainfall, and weathering. At the same time, there are very few devices for the scouring effect of water flow on the rock mass of the bank slope of the reservoir.

Embodiment Construction

[0019] see figure 1 , Figure 5 , a device for simulating the scouring effect of water flow on the slope rock mass of the reservoir bank under the conditions of sunshine, rainfall and weathering includes a test chamber 1 and a spiral agitator shaft 4 arranged in the test chamber, and the test chamber 1 is preferably Drum-shaped, with spiral agitator blades 5 on the helical agitator shaft 4, the helical agitator shaft 4 communicates with the motor 6 outside the test chamber 1, and the rotation of the motor 6 drives the agitator to rotate to generate water in the test chamber 1 along the container. Inner wall flow power, four rock sample containers 2 are respectively arranged along the four equal parts of the circumference of the test chamber 1, and the edge of the rock sample container 2 is connected with the edge of the test chamber 1 and communicated with the test chamber 1. The inner wall of the rock sample container 2 is provided with a sealing layer, such as Figure 4 An...

Abstract

A device for simulating reservoir bank slope rock scouring effects of water flow under sunshine rainfall and weathering comprises a test bin, a spiral stirrer shaft, a sunlight simulator, an air blower and a ring-shaped water atomizer. The spiral stirrer shaft is provided with spiral stirrer blades. The sunlight simulator is arranged at the axis of the ring-shaped water atomizer, sunlight duration and sunlight intensity adjustment can be performed on the sunlight simulator, sunlight and thermal radiation can evenly shine rock samples, and accordingly the influences of the sunlight intensity and sunlight temperature on naked rock sample surfaces are simulated. The air blower blows air into the test bin, and cyclic wetting and drying test and weathering simulation can be performed under the matching of the sunlight simulator. The device has the advantages that the independent influences and effects on the rock samples caused by factors such as the speed of rock sample scouring by water flow, the heights of the rock samples intruding the water, cyclic wetting and drying time and times of the rock samples, rainfall, sunlight duration and temperature can be considered.

Description

technical field [0001] The invention relates to the influence of water scour on the rock mass of reservoir bank slope and the effect of water level rise and fall on the rock mass in the ebb and flow zone when natural conditions are considered in the field of rock and soil mechanics test, such as sunshine, rainfall, weathering, etc. technical background [0002] Among the existing test devices, there are relatively few test devices and equipment related to the impact of water flow erosion and water level rise and fall on the rock mass in the ebb zone, especially when considering various common natural conditions including sunshine, rainfall, and weathering. At the same time, there are very few devices to carry out the scouring effect of water flow on the rock mass of the bank slope of the reservoir. The design of this device can more intuitively simulate the impact of reservoir water erosion and water level rise and fall on the rocks in the sinking zone of the bank slope unde...
