Test device for simulating marine environment dynamic and static combined concrete loading

Abstract

The invention belongs to the technical field of marine engineering concrete material durability test equipment, and particularly relates to a test device for simulating marine environment dynamic andstatic combined concrete loading; compared with the prior art, the device has the advantages that 1, the structure is simple, the installation is convenient, the automation degree is relatively high,manpower and material and time cost are saved, and meanwhile, the overall control function of a control box and the real-time detection and recording function are realized, and the accuracy is improved; 2, an upper water level sensor, a lower water level sensor, a communication water pipe, a test box and a liquid storage box are matched to carry out a dry-wet circulation test, so that clear boundaries of an underwater area, a tidal area and a wave-splashing area can be ensured, the underwater area is always in the soaking environment, the tidal area is located in the soaking and drying environment, and the wave-splashing area is in a spraying environment; and 3, the characteristics of chemical and mechanical coupling and dynamic and static combined loading are considered, so that the testdevice is more suitable for the environment where the concrete is in service, and can be widely applied to the concrete durability test occasions.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of durability test equipment for marine concrete materials, and in particular relates to a test device for simulating marine environment static and dynamic combined loading of concrete. [0003] Background technique: [0004] Over the years, people have conducted research on the durability of concrete caused by chloride ion attack, but most of them revolved around a single influencing factor. However, concrete in actual engineering does not work under a single factor, and generally bears the joint action of two or more factors. When multiple factors act together, the damage to concrete is not a simple superposition of the effects of each single factor. The interaction of various factors complicates the damage process of concrete in the actual service process. In practical engineering, almost all concrete will bear different types of loads, and the loads often cause the generation and expansion of mic...

AI Technical Summary

Problems solved by technology

This type of test method accelerates the durability degradation of concrete structures by increasing the temperature, relative humidity, concentration of corrosive media or introducing factors that do not exist on site (such as current, etc.), which leads to the fact that the durability erosion mechanism, process and results of concrete structures do not match the actual conditions. , the research results are difficult to apply in practical engineering

In addition, the existing research methods on the durability of concrete are mostly aimed at the material level, and there is a lack of test methods for the durability of concrete structures.
