Description

technical field [0001] The invention relates to the field of concrete pavement structure health monitoring, in particular to a cement concrete pavement health monitoring sensor fixing device, which is used for fast and accurate modular installation of structure monitoring sensors. Background technique [0002] Demand analysis: Concrete pavement has always been a very common structural form in the field of roads and airports because of its reliability and durability. With the continuous increase of traffic load and the diversification of load forms, more serious challenges are presented to the design method and maintenance method of concrete pavement structure. Taking civil airports as an example, by the end of 2011, my country had 180 transport airports. According to the "Twelfth Five-Year Plan for China's Civil Aviation Development", by 2015, there will be more than 230 transport airports in my country. Corresponding to the vigorous development of the aviation industry, on...

Problems solved by technology

[0009] Existing problems: The existing pavement structure monitoring is mainly aimed at some test roads or full-scale indoor tests. The installation of sensors is mainly based on simple bracket structures. Paste at specified location

Due to the different types and structures of sensors in each test, these brackets have various forms, most of which are manually fixed, and the operation is cumbersome, requiring very meticulous work ability and strict protection

Since the structure of the stent itself has not been carefully screened and demonstrated, there are major problems in its versatility, reliability, and stability.

At the same time, the sensor fixing process requires a lot of manual operations, including point fixing, drilling, fixing, finding the height, determining the sensor orientation, binding, etc., which is very time-consuming. At the same time, human factors have a great impact on the installation results and cannot be promoted.

Moreover, these brackets themselves have a single purpose, and a single bracket is mostly used to fix a sensor. For areas with a large demand for information, the sensors are densely arranged, and it is difficult to comprehensively utilize a single type of bracket.

Due to the interlacing of brackets and cables, a large number of appendages have an impact on the measurement object (concrete structure), which is not conducive to structural safety on the one hand, and makes the measurement results less convincing

[0010] On the other hand, the pouring process in the construction of concrete pavement is very fast and extensive. The concrete pouring in the indoor test or test road is not the actual construction process and technology. have been modified, so the existing method cannot be used for large-scale construction
