Real-time monitoring device and operation method for water and mud inrush disasters in tunnels and underground engineering

Abstract

The invention discloses a real-time monitoring device for water-inrush and mud-burst disasters in tunnels and underground engineering and an operation method. The real-time monitoring device comprises a model box, a ground stress simulation system, a water injection device, a monitoring system and a control system, wherein the model box is used for containing a water-body-containing similar material so as to simulate a rock body; the ground stress simulation system is used for applying a certain pressure to the water-body-containing similar material in a system of the model box and simulating a ground stress; the water injection device is used for injecting a certain amount of water into the water-body-containing similar material, a pressure controller and a flow control valve are mounted on the water injection device, are connected with a serve controller and are used for controlling simulated osmotic pressure at any time; the monitoring system comprises a sensor and a muddy water amount collecting device, the sensor is arranged in the model box, the muddy water amount collecting device is communicated to the inside of the model box, and the monitoring system is used for monitoring and collecting information before and after the occurrence of the water-inrush disasters in real time; and the control system is used for controlling the water injection device and simultaneously processing data collected by an information monitoring system.

Description

technical field [0001] The invention relates to a comprehensive real-time monitoring test device and operation method for water and mud inrush disasters in tunnels and underground engineering. Background technique [0002] At this stage, with the rapid development of economic construction, a large number of major infrastructure projects such as water conservancy and hydropower projects, railway and highway transportation projects have accelerated the pace of construction, which has greatly promoted the construction of tunnel projects. With the shift of the focus of water conservancy, hydropower and traffic engineering construction to the western mountainous and karst areas with extremely complex terrain and geological conditions. When constructing underground tunnels or excavating roadways, the complex tunnel environment during construction can easily induce large-scale and sudden water and mud inrush disasters, causing casualties, delays in construction, damage to machinery...

AI Technical Summary

Problems solved by technology

Chinese scholars have carried out a lot of research work on groundwater seepage and water and mud inrush disasters, but there are also obvious weaknesses. It is impossible to conduct comprehensive comprehensive monitoring on the occurrence process of water and mud inrush disasters, and the records of water and mud inrush disasters are not enough. timely and accurate

At this stage, experts and scholars are still not very clear about the catastrophe evolution mechanism of water-rich tunnels, lack of analysis methods and related equipment for the dynamic catastrophe evolution process of water inrush, and have not been able to propose a feasible technology for monitoring tunnels at the source of water and mud inrush disasters means
