Portable high-precision tunnel deformation monitoring equipment

Abstract

The invention relates to portable high-precision tunnel deformation monitoring equipment which comprises a mounting plate. Connecting plates are symmetrically and fixedly arranged on the mounting plate; a mounting box is arranged on the right side of the mounting plate; a connecting block is fixedly arranged on the left side of the mounting box; the connecting block is arranged between the connecting plates; through holes are formed in the connecting plates; a connecting hole is formed in the connecting block; a connecting pin shaft is arranged in the through holes and the connecting hole in apenetrating manner; a partition plate is fixedly arranged in the inner cavity of the mounting box; a laser scanner is fixedly mounted at the top of the partition plate; a fan is fixedly mounted at the bottom of the partition plate; and a mounting table is fixedly arranged on the right side of the mounting box, the laser scanner lens is located in the mounting table, and an air duct is formed in the inner cavity of the mounting table so that mounting and dismounting of the monitoring equipment are facilitated, the monitoring equipment can be repeatedly used for different monitoring sections, and the monitoring efficiency is improved; meanwhile, the cleanliness in front of the lens of the detection equipment is guaranteed and the detection accuracy is improved.

Description

technical field [0001] The invention relates to a portable high-precision tunnel deformation monitoring device, which belongs to the technical field of tunnel construction. Background technique [0002] Tunnel monitoring and measurement is one of the three pillars of the new Austrian method. It plays an important role in the adjustment of construction technology during tunnel construction, the selection of support structures and the selection of support structure parameters. In the tunnel monitoring and measurement work, Tunnel convergence monitoring plays an important role in judging the stability of the surrounding rock and the rationality of the construction method, and the laser scanner mainly locates the scanned object through laser reflection, so as to determine its spatial form. A large amount of dust is often generated during the process, which often causes the laser projection to reflect on the surface of the dust particles, but fails to reflect on the correct surfa...

[0002] Tunnel monitoring and measurement is one of the three pillars of the new Austrian method. It plays an important role in the adjustment of construction technology during tunnel construction, the selection of support structures and the selection of support structure parameters. In the tunnel monitoring and measurement work, Tunnel convergence monitoring plays an important role in judging the stability of the surrounding rock and the rationality of the construction method, and the laser scanner mainly locates the scanned object through laser reflection, so as to determine its spatial form. A lot of dust is often generated during the process, which often causes the laser projection to reflect on the surface of the dust particles, but fails to reflect on the correct surface of the scanned object, thus affecting the accuracy and reliability of scanning
