Description

Technical Field

[0001] The invention belongs to the technical field of road construction, and relates to a road surface optical fiber laying technology, and specifically to a road surface optical fiber laying device and a laying method integrating grooving and laying. Background Art

[0002] As a basic and leading industry for economic and social development, transportation has a strategic and global impact on the development of urban economy. In this context, the construction of smart highways and smart airports has become one of the main directions of the development of modern transportation infrastructure. Under the influence of complex traffic loads, the health status of existing highways continues to deteriorate, and the health status of pavement structures is difficult to assess. If the best maintenance opportunity is missed, the maintenance cost will increase significantly. In addition, with the increase in demand for air travel, the frequency of aircraft takeoffs and landings continues to increase, which will lead to a sharp increase in the number of times airport runways are impacted by aircraft tires, which will seriously damage the health of airport runways and reduce their service life. Therefore, it is particularly important to implement real-time monitoring of pavement health and traffic flow. This is not only an important means to prevent potential pavement damage, ensure traffic safety, and extend the service life of pavements, but also an indispensable way to achieve pavement intelligence.

[0003] Fiber optic sensing technology is used to transmit pavement health status data and traffic flow data, which is crucial for pavement health status monitoring and traffic flow monitoring. Therefore, fiber optic sensing technology plays a very important role in the construction of intelligent pavements, and will become one of the important measures to promote intelligent highways and intelligent airport pavements in the future. However, pavement optical fiber laying technology, as an important means for the large-scale application of fiber optic sensing technology in roads, still has many shortcomings. For example, traditional optical fiber laying operations are a complex and time-consuming process involving the coordinated operation of multiple different construction equipment. First, special grooving equipment is required to dig a trench on the predetermined path, and then the optical fiber is laid into the trench manually or using other equipment. During laying, it is impossible to ensure that the optical fiber remains straight, and it is difficult to ensure the laying quality, resulting in the bending of the optical fiber, which reduces the accuracy of the monitoring results. Summary of the invention

At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the techniques, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary inventions may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0064] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description.
