Transmission tower foundation defect identification has become more and more important. However, conventional detection methods are inefficient, which can cause secondary damage to the structure, and are limited by the inability to achieve large-scale detection. For this reason, the SSP technology is introduced in this paper which is applied to the foundation defect identification of transmission tower. Firstly, the feasibility of applying SSP technology to the foundation defect identification of transmission tower is analyzed. Secondly, the field test flow and data processing of SSP technology for foundation defect identification of transmission tower are introduced. Finally, the basic model of a transmission tower is tested to verify the feasibility of SSP technology for the foundation defect identification of transmission tower.
In order to clarify the relationship between the efficacy loss of strain clamp joints and the crimping quality, three groups of clamp joints, crimped under unbalanced conditions at both ends, naming NY-240/40, NY-400/35 and NY-630/45 were selected and then subjected to tensile tests and X-ray inspection. After a detailed analysis of the experimental results, it can be seen that under the condition of unbalanced crimping quality, the efficacy loss all occurred on the side with better crimping quality, which provides an instructive reference for the crimping technique of strain clamps in actual project construction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
