Shield tunnel segment internal micro-damage detection device and method

Abstract

The invention discloses a shield tunnel segment internal micro-damage detection device and method. The shield tunnel segment internal micro-damage detection device comprises a steerable visiting device, a sound signal monitoring module, a telescopic connecting framework, a detachable mobile power source and a segment monitoring cloud platform, wherein the front end of the telescopic connecting framework is connected with a viewfinder through a universal coil pipe; the viewfinder is used for detecting an image signal in the shield tunnel segment; a sound signal monitoring module and a GPS positioning chip are installed on the telescopic connecting framework, the sound signal monitoring module is used for monitoring abnormal sound generated in the damage process of the segment, and the GPS positioning chip is mainly used for positioning the installation position of the whole detection device; and the tail part of the telescopic connecting framework is connected with the detachable power supply, and the power supply provides power for the sound signal monitoring module, the GPS positioning chip and the viewfinder, so that the normal work of each component is ensured.

Description

technical field [0001] The invention discloses a device and method for detecting micro-damage inside a shield tunnel segment. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the continuous improvement of the level of economic development and people's requirements for quality of life, traditional urban roads have been unable to meet the growing traffic volume, and urban traffic has gradually deteriorated. In order to improve the urban traffic environment and promote the sustainable development of the city, the subway came into being. The shield tunneling method has very obvious advantages in subway construction. The shield tunneling method has the advantages of fast construction speed, small impact on the surrounding environment, and high safety. As a composite product of segment assembly, shield tunneling, segment detection is an important t...

AI Technical Summary

Problems solved by technology

In the process of tunnel segment inspection, core drilling often needs to cut steel bars, which will cause damage to the original structure and is inefficient; most inspection personnel still need regular inspections, and subway operation pipelines may cause safety problems for inspection personnel. At the same time, due to Manual inspections have poor timeliness in reporting disasters, and cracks in tunnel segments are often discovered only when they extend to the surface, which will seriously affect project safety and social and economic benefits

[0004] In addition, domestic researchers have done little research and development on internal micro-damage visual detection equipment for shield tunnel segment detection, and there is no complete set of internal visual detection devices for shield tunnel segments
