To address the problems of data distortion in the
current tunnel mobile measurement system in the detection of tunnel crosssection
and apparent disease information and the difficulty in practicality due to the
large volume and weight, an Ishaped mobile threedimensional scanning trolley is designed and developed. The main
structure uses carbon fiber materials and a folding design to achieve a system
weight of less than 30 kg, which can be quickly transferred to multiple cities
by air transport by two operators. The results show that: (1) The system can
directly collect the track information, providing a reliable benchmark for the
calculation of tunnel structural parameters, and the calculation results are
consistent with the engineering definition. (2) Through field engineering
application, the data collection is efficient. Compared with the station data, the
data results show that the structural point cloud data error is within ± 3 mm, ensuring the accuracy and availability of the data. (3) The
system can be applied to both mined and shield tunnels with good detection
effect.
