AI Technical Summary

Technical Problem

Existing technologies make it difficult to identify defects in the concrete beneath ultra-large-tonnage segmented spherical joint structures with high density and high precision, resulting in delayed control response, missed optimal repair windows, and impacting structural quality, safety, and construction efficiency.

Method used

A three-dimensional parametric finite element model is used to set sampling points. Strain sensors and temperature sensors are combined to determine defects through strain data processing and mapping relationships. Repairs are performed using an industrial endoscope, and the defect risk index is evaluated for early warning and vibration equipment parameter adjustments.

Benefits of technology

It achieves early identification and dynamic prediction of concrete defects, improves structural quality and safety, construction efficiency, and enhances the intelligent management and control capabilities of the construction site.

Abstract

The invention relates to the technical field of concrete defect identification, and discloses a concrete defect state identification and passive detection combined control method under a super-tonnage block type spherical hinge, which is used for solving the problem that defect prediction cannot be realized during concrete defect identification, and comprises the following steps: setting sampling points in a concrete structure in a layered manner, acquiring strain monitoring data of each sampling point, judging whether the sampling points have defects or not, if so, performing grouting repair intervention treatment, if not, acquiring risk parameters of concrete defects, and evaluating according to the risk parameters to obtain defect risk indexes; whether the sampling points have the risk of concrete defects or not is judged, if the sampling points have the risk of concrete defects, early warning and vibration equipment parameter adjustment are carried out on the sampling points according to the defect risk indexes, the structure quality safety and the construction efficiency are effectively improved, and the engineering field intelligent management and control degree is improved.
