The above defects can affect the accuracy and timeliness of tunnel monitoring data, and after the measuring point is damaged, more time, labor and material resources are spent for repairing the measuring point.

According to the patent technology of the existing measuring point reflecting device, some reflecting pieces are fixed by adopting a support structure, so that the problem that the reflecting pieces are easy to fall off due to external influence is solved; some diodes are arranged in the transparent shell, so that the problem of measurement accuracy in a dark and dusty environment is improved, but the problems of high manufacturing cost and practicability are ignored; some measuring point reflecting devices are connected by expansion bolts to achieve the purpose of recycling, but due to the complex environment of a construction site, the measuring points are often knocked to be inclined or knocked down during construction of construction machinery such as an excavator.
