Abstract

The invention discloses a tunnel overall deformation monitoring device based on GPS positioning, which comprises a laser range finder and a GPS positioning device, and is characterized in that a vehicle body is fixedly provided with a vertical column, the upper end of the vertical column is fixedly provided with a transverse pipe in the transverse direction, the transverse pipe is internally provided with a horizontal rotating shaft through a bearing, the tail end of the horizontal rotating shaft is provided with a balance box through a hinge, and the GPS positioning device and the laser range finder are located at the inner side or the outer side of the balance box. The tunnel overall deformation monitoring device based on GPS positioning is simple in structure, easy to manufacture and low in cost, is a tunnel monitoring and measuring mode applied to conventional tunnel construction, realizes automatic and real-time measurement and can achieve a purpose of timely warning. The measurement precision is from 0.01mm to 10mm, and detection parameters can be adjusted according to tunnel geological conditions. The tunnel overall deformation monitoring device disclosed by the invention can carry out continuous, intelligent, instant and stable measurement on tunnel deformation, and a new approach is opened for a non-contact measurement method.

Description

technical field [0001] The invention relates to underground tunnel deformation monitoring technology, in particular to a GPS positioning-based overall tunnel deformation monitoring device. Background technique [0002] In recent years, with the rapid development of China's national economy, new railways, highway tunnels, underground railways and other underground engineering projects are increasing day by day. With the rapid development of underground engineering, more and more attention has been paid to the deformation measurement of underground engineering structure system during construction. Tunnel deformation monitoring and measurement is the work of regular observation and measurement of the deformation and stability of surrounding rock, ground surface, and support structures during tunnel construction. It is necessary to ensure project safety, guide design and construction, and optimize construction technology. link. The deformation monitoring of the tunnel surround...
