Hand-held subway tunnel structure damage investigation data recorder and recording method therefor

Abstract

The invention relates to a hand-held subway tunnel structure damage investigation data recorder and a recording method therefor. The hand-held subway tunnel structure damage investigation data recorder comprises a touch screen and a circuit board connected to the touch screen. The circuit board is provided with a memory module, a graphic processing module, a basic information management module and a survey task management module. The recording method comprises the following steps of starting the basic information management module by the touch screen according to a survey request transmitted by the survey task management module, generating a subway tunnel structure layout map needing survey, displaying the subway tunnel structure layout map, acquiring on-site subway tunnel images in real time by the graphic processing module, recording damage data and satellite information in the subway tunnel structure layout map by a standard graphic marking method according to a damage type layout map, carrying out quantization treatment on the damage data, and storing the quantized damage data in the memory module. Compared with the prior art, the hand-held subway tunnel structure damage investigation data recorder and the recording method therefor have the advantages of high digitization, high informatization, high timeliness, high accuracy and less intermediate processing processes.

Description

technical field [0001] The invention relates to a recorder and a recording method in the field of subways, in particular to a hand-held recorder and a recording method for structural disease investigation data of subway tunnels. Background technique [0002] Due to the special environment of the subway project, after the operation of the subway, the subway disease has the characteristics of strong concealment, difficult diagnosis and treatment. The subway inspection during the operation period can neither damage its original structure nor affect the normal operation of the subway. Therefore, non-destructive testing, health diagnosis, and common disease treatment of subway engineering structures have become issues of concern to the engineering and academic circles. If there are cracks in the tunnel structure, the erosive groundwater will seep into the tunnel structure, which will lead to the corrosion of the tunnel lining steel bars and structural concrete corrosion, which wi...

AI Technical Summary

Problems solved by technology

[0004] At present, the acquisition of operating subway disease information mainly relies on manual field investigation. Due to the constraints of subway operation, the effective operation time is less, the work efficiency is low, and the operation time and number of personnel are restricted, which has gradually failed to meet the needs of network operation.

In addition, in the traditional artificial disease investigation, the investigators check the disease information on the spot and mark it on the paper recording
