Summarized information monitoring system of tunnel

Abstract

The invention relates to a summarized information monitoring system of a tunnel. The summarized information monitoring system mainly comprises an automatic frequency monitor, an automatic blast vibration monitor, an automatic video acquiring monitor, an automatic three-dimensional section monitor, a wireless route repeater, a wireless high-speed repeater station, a network exchanger and a monitoring host. The monitoring host is connected with the network exchanger, the wireless high-speed repeater station and the wireless route repeater sequentially; the wireless route repeater is connected with the automatic frequency monitor, the automatic blast vibration monitor, the automatic video acquiring monitor and the automatic three-dimensional section monitor respectively; the automatic frequency monitor is connected with a vibration-wire sensor; and the automatic blast vibration monitor is connected with a three-direction or one-direction speedometer. The summarized information monitoring system disclosed by the invention can implement monitoring, pre-alarming and forecasting on surrounding rock pressure, rock mass vibration and clearance variation.

Description

technical field [0001] The invention relates to a tunnel comprehensive information monitoring system, which is suitable for tunnel construction monitoring measurement and early warning and forecasting, and belongs to the field of tunnel monitoring. Background technique [0002] my country is a mountainous country, and tunnels account for a large proportion of the construction of railways and highways in mountainous areas of our country. At present, more and more new Austrian methods are used in tunnel engineering in my country. The main feature of building tunnels with new Austrian methods is to monitor the dynamics of the tunnel surrounding rock after excavation through many measurement methods, and use them to guide tunnel support. Design and construction of protective structures. As an important part of NATM tunnel construction, the accuracy and timeliness of tunnel monitoring and measurement work is directly related to the safety and progress of tunnel construction. How...

AI Technical Summary

Problems solved by technology

[0005] 1. There are many human-influenced factors and construction-influenced factors in the data collection process, the authenticity of the data cannot be guaranteed, and the deformation of the surrounding rock cannot be accurately reflected

[0006] 2. The automation and informatization of monitoring and measuring equipment are low, and the workload of data post-processing is large, which takes up a lot of manpower and material resources, and cannot reflect the deformation of engineering structures in time

[0007] 3. The data acquisition is slow, and the tunnel is relatively dark. If the measurement point is not accurately located, measurement deviation is prone to occur

[0008] 4. Data transmission, storage, and information management cannot meet the requirements of information construction management, and cannot guide engineering information design and construction in a timely manner

[0009] 5. Unable to conduct video surveillance on the tunnel and grasp the picture information

[0010] 6. It is necessary for surveyors to enter the tunnel to work, which is easy to affect the construction and has potential safety hazards

[0011] 7. The data obtained by monitoring and measurement cannot be quickly analyzed on the computer, and the early warning and forecast
