Abstract

The invention discloses a matrix structure for measuring the temperature and humidity inside concrete and an arrangement method thereof. The matrix structure includes a plurality of temperature sensors and humidity sensors arranged inside the concrete, and each temperature sensor and a humidity sensor are bound together to form a sensor Groups, sensor groups on the same horizontal plane and sensor groups on the same vertical plane are distributed in a matrix; in addition, the present invention also discloses a corresponding layout method; the present invention can monitor and collect multi-point temperature and humidity data inside the concrete in real time, and measure The structure can be quickly and conveniently arranged in combination with the concrete pouring construction technology, which provides data support for exploring the coupling principle of temperature and humidity in concrete, and plays a positive guiding role in the prevention and control of concrete cracks.

Description

technical field [0001] The invention relates to the technical field of concrete construction of water conservancy projects, in particular to a matrix structure for measuring the temperature and humidity inside concrete and an arrangement method thereof. Background technique [0002] Concrete is an indispensable building material for water conservancy and hydropower projects due to its good mechanical properties and durability. However, due to its harsh working environment, complex load combination and the material properties of concrete itself, dam concrete will suffer various types of damage and damage since it is poured, which affects the service safety performance of the dam. [0003] Among them, cracking is the most common damage and damage form of concrete dams. Although hydraulic engineers and scientific researchers have paid attention to the problem of hydraulic concrete cracking very early, they have done a lot of work and achieved a lot of achievements, but so far ...

Problems solved by technology

[0006] At present, there are many devices that can be used to measure the internal temperature of concrete, and the technology is relatively mature, but there are still relatively few devices that can be used to accurately measure the internal humidity of concrete, and the reliability is also low. It can simultaneously measure the temperature and humidity data of multiple points in the concrete. The technology of real-time monitoring is even less involved, and affected by the processes of feeding, vibrating, and curing during concrete pouring, small instruments and components such as sensors are particularly vulnerable to damage, and once the concrete is poured, it cannot be damaged. Some of them are repaired and replaced, which often affects the safety monitoring, scientific research experiments and long-term operation of hydraulic engineering concrete structures, and some effects are even destructive. Therefore, it is necessary to design an effective measurement structure and layout method to measure concrete structures. It is necessary to monitor and collect internal temperature and humidity data, which is necessary to study the distribution of temperature and humidity inside concrete, and to study the stress evolution characteristics of concrete under the coupling of temperature and humidity based on test results and numerical analysis. It is of great theoretical and engineering significance to reveal the conditions under which cracks occur in concrete.
