Method for fixing sensor

Abstract

The invention discloses a method for fixing a sensor. The method includes the steps of using carbon fiber cloth to fix the sensor on the surface of concrete, enabling the carbon fiber cloth to tightly wrap three faces of the sensor through epoxy resin adhesives, reserving a section of the carbon fiber cloth, and after the epoxy resin adhesives are completely solidified, using the reserved carbon fiber cloth to fix the sensor on the surface of the concrete through epoxy resin adhesives. The method for fixing the sensor is easy to operate, high in operating flexibility, small in sensor size limitation, suitable for various complex environments, safe, reliable and good in durability, the sensor can be firmly and tightly fixed to the surface of a concrete structure, the good coupling effect is achieved, damage to the concrete structure is avoided, the sensor can be effectively protected through the fact that the sensor is wrapped by the carbon fiber cloth, the service life of the sensor is prolonged, and the method for fixing the sensor is particularly suitable for health detection of concrete buildings in special environments such as high-speed rail bridges.

Description

Technical field [0001] The present invention involves a method of fixing sensors, especially cement sensors on the surface of the concrete, and specifically involves a sensor fixing method that can be applied to a special environment and has no damage to the concrete structure. Background technique [0002] The sensor is widely used in the health monitoring of concrete structure, but now the fixing party V of the sensor is mainly based on the bolt fixing method. Although this method is simple and fast, it will inevitably cause damage to the concrete structure, especially the particularity.For concrete structures in special environments such as high -speed rail bridges, once the concrete structure causes damage or the rust of bolts causes the sensor, it will inevitably leave serious hidden dangers to the normal operation of the high -speed rail.On the other hand, in the process of long -term use, it is difficult to control the coupling effect between the sensor and the concrete st...

Problems solved by technology

[0002] Sensors are widely used in the health monitoring of concrete structures, but the current method of fixing the sensors is mainly the bolt fixing method. Although this method is simple and fast to operate, it will inevitably cause damage to the concrete structure, especially For concrete structures in special environments such as high-speed rail bridges, once the concrete structure is damaged or the bolts are rusted and loosened to cause the sensor to fall off, it will inevitably leave serious hidden dangers to the normal operation of the high-speed rail.

On the other hand, during long-term use, it is difficult to control the coupling effect between the sensor and the concrete structure due to the rust and looseness of the bolts, which often reduces the accuracy and sensitivity of the sensor, thereby affecting the accuracy of the entire monitoring system. Therefore, it is particularly important to find a non-destructive sensor fixing method that is adaptable to various complex environmental changes for the health monitoring of concrete structures.
