Observing device and method for filler changing process at different water flow velocities

Abstract

The invention relates to an observing device and method for filler changing process at different water flow velocities. The filler changing process observing device is constituted by a testing water pipe, a current speed adjusting device, a flowmeter, a detachable transparent observing device, and a high-speed camera. During testing, the current speed adjusting device disposed on a water inlet in a testing device is used to adjust the current speeds. The anemometer is used to acquire the current speeds in a real-time manner, and is used to record current speed information by a data connecting line, and the recorded current speed information is displayed on a current flow display. The detachable transparent observing device is made of high strength transparent tempered glass, and then real-time observation of inside filler changing information is realized. Fillers having a certain particle grading composition are disposed in a filling area in a filled manner, and a permeable clapboard is used as the left wall of the filling area. Under action of waterpower scouring and a screen, the fillers are moved, and the automatic particle diameter grading of the fillers is carried out, and then the high speed camera is used for whole process recording, and inside information is acquired in a real-time manner. The screen is connected with a current speed sensing device, and the real-time current speed changing is displayed on a current speed sensing receiving device.

Description

technical field [0001] The invention relates to a device and method for observing the change process of fillings, in particular to a device and method for real-time observation of the change process of fillings at variable flow rates. Background technique [0002] Tunnels (caves) and underground projects are control projects for the construction of national infrastructure projects such as transportation, water conservancy and hydropower, and involve many engineering fields such as roads, railways, hydropower, cross-basin water transfer, and mine resource development. Especially with the gradual implementation of the national science and technology strategic development plan, the traffic road network has expanded in depth to the west where the mountains are all over the place. However, the water and mud inrush disaster encountered in the tunnel construction process is extremely serious, and the study of its complex dynamic evolution process is an effective way to control the ...

AI Technical Summary

Problems solved by technology

At present, there are few instruments used to observe the change process of karst pipeline filling, the visibility of the test system is poor, and it is difficult to observe the change of filling in real time

At present, some scientific workers try to observe the experimental process by simulating transparent similar materials, but the similar materials cannot fully reflect the properties of the filling, and the reliability of the test results is greatly reduced

On the other hand, the corresponding simulation devices and methods have yet to mature
