Problems solved by technology

Although this method makes up for some shortcomings of the manual measurement method, such as the continuous dynamic monitoring of the segment structure, the collection of massive data, and the intelligentization of safety judgment methods, etc., there are still some shortcomings in practical applications: for massive monitoring data It is difficult to synchronize the analysis and visualization in real time, and it is impossible to release this information on the construction site to all personnel involved in the construction at the first time

Embodiment Construction

[0060] The visual early warning device and method for structural stress of subway shield tunnel segments proposed by the present invention reflect the structural stress by generating induced potentials of different frequencies through the vibrating wire vibration of the sensor. Acquisition, the collection of temperature data is realized through the thermocouple temperature module, the data exchange between the main equipment is realized by wireless communication, and the data processing module is embedded in the visual display terminal to realize the on-site calculation and real-time display of physical quantities. Finally, through The safety warning device emits bright lights of different colors to achieve different levels of pre-alarms.

[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0062] Such as figure 1 , 2 As shown, the embodiment of the present invention provides a subway shield ...

Abstract

The invention belongs to the technical field of shield tunnel segment structure safety monitoring, and provides a subway shield tunnel segment structural stress visual warning device and an operating method thereof. The device comprises a structural stress sensor, a micro data acquiring device, a visual display terminal, a multi-channel data transmitting device and a safety warning device. By the aid of the device and the operating method, subway shield tunnel segment reinforcement stress values and concrete strain values can be acquired continuously, acquired results can be displayed in real time on the inner annular face of a segment to the detected to provide convenience to operators in a tunnel for observing in real time, real-time warning of segment stress can be realized in a manner of photochromic warning, requirements of grasping segment structure stress data information by the operators in the tunnel are met, and automatic safety warning is realized.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring of the segment structure of a shield tunnel, and in particular relates to a stress visualization early warning device for a segment structure of a subway shield tunnel and a working method thereof. Background technique [0002] As an important part of the urban public transportation system, the subway is currently in a stage of vigorous development, and its demand is still increasing day by day. The shield tunneling method has been widely used in the field of subway construction due to its high degree of automation, fast construction speed, no influence of climate, and less impact on ground buildings and road traffic. [0003] Due to the complexity of geological and hydrological conditions, there are certain risks in shield tunneling construction. The construction of important sections such as shield starting, receiving, passing through the wind shaft, and connecting passages will cause...
