Abstract

The invention provides a maintenance monitoring and quality evaluation method and system for concrete prefabricated members. The maintenance monitoring and quality evaluation method and system adopt an ultra-high frequency detection device to collect electromagnetic wave reflection spectrum data of each measuring point of the concrete members placed on a maintenance pedestal and sends the collected electromagnetic wave reflection spectrum data to a server. The server analyzes the received electromagnetic wave reflection spectrum data to obtain the dielectric coefficient [Epsilon]rt of the concrete members at each curing age t. The server analyzes the difference value between the concrete moisture content Wt of each measuring point and the corresponding Wt0, and transmits a signal to a spraying device according to the difference value, and the spraying device moves to the corresponding measuring point position and sprays water to the measuring point to enable the concrete moisture content at the measuring point reach Wt0. The maintenance monitoring and quality evaluation method and system can solve the problems of insufficient maintenance monitoring and lagging quality evaluation ofthe concrete members, and realizes real-time adjustment of concrete members maintenance conditions and process evaluation of maintenance quality.

Description

technical field [0001] The invention relates to a maintenance monitoring and quality evaluation method and system for concrete prefabricated components. Background technique [0002] Concrete is a very important structural material, but it must be properly maintained in order to have good mechanical properties and durability. The main control parameters in the concrete curing process are temperature, humidity and curing time, which have a great influence on the performance of concrete. At present, the actual engineering maintenance mainly adopts the means of sprinkling water on the concrete surface, and the operation and implementation are not difficult, but it is difficult to effectively control or there is no uniform and reasonable maintenance standard in the actual engineering, so there are many phenomena of concrete performance degradation caused by poor maintenance. . Currently, there is no effective method to monitor whether concrete curing is sufficient or under wha...
