Embodiment approach

[0075] Both the geophone and the excitation hammer (vibration source) are a three-dimensional array combination structure, and the arrangement is as follows: figure 1 As shown, the size of the array is consistent with the combined structure, in this case 50cm x 60cm. In this example, the steel shell concrete structure is a steel shell concrete pipe joint, and the size of the steel shell concrete pipe joint is 3m×3m, which can be divided into 30 combined structures of the same size, as shown in figure 2 shown. Therefore, the mobile acquisition system needs to scan 30 combined structure areas to quickly complete all data acquisition in the entire area. The required number of geophones is 42, the number of excitation hammers is 35, the distance between the geophones is 10cm, and the excitation hammer is arranged at the midpoint of two adjacent geophones. The geophones have the same frequency and are velocity type geophones with a natural frequency between 100 Hz and 400 Hz, fo...

Abstract

The invention provides a steel shell concrete structure defect detection method, which comprises: a data collection step: obtaining global waveform data, wherein the global waveform data is formed ona steel shell concrete structure through excitation; an information identifying step: processing the global waveform data to obtain the sub-global waveform information corresponding to any one or anymultiple components in the steel shell concrete structure; and an imaging step: extracting the feature values in the sub-global waveform information, and imaging to obtain a three-dimensional void thickness image. Accordingly the present invention further provides a steel shell concrete structure defect detection system, a steel shell concrete structure defect detection apparatus, and a computer readable storage medium for storing computer programs. According to the present invention, with the method, the system and the apparatus, the concrete filling compaction and the detect size in the large volume steel shell can be subjected to rapid detection and rapid three-dimensional imaging, such that various performance indexes of the steel shell concrete can be ensured so as to ensure the actual use.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a method, system, device and storage medium for detecting defects in steel shell concrete structures. Background technique [0002] Steel shell concrete structure, including steel shell structure (cavity form) and concrete filled in the steel shell structure, the steel shell structure is composed of inner and outer steel plates, and transverse and longitudinal reinforcement ribs are welded in the inner and outer steel plates The surface of the cavity strengthens the strength and rigidity of the shell, and concrete fills the interior of the shell to improve the overall rigidity and strength of the pipe joint structure. It can be used for long-span immersed tube joint structures under high water pressure and large buried depth conditions and other special requirements for immersed tube joint structures. At present, the steel shell concrete structure has been widely used in the con...
