Remote survey system and survey method for tunnel construction site

Abstract

A remote survey system for a tunnel construction site includes a tunnel grouting amount surveying device, a tunnel internal stress surveying device and a remote monitoring device. The tunnel groutingamount surveying device includes a three-dimensional laser scanner and a rotating seat, and the rotating seat is provided with a locator and an infrared sensor. The tunnel internal stress surveying device includes a strain sensor, a signal collector, a signal analysis module and a remote communication transmitting module which are connected in sequence. The remote monitoring device includes a maincontroller, a remote communication receiving module and a displayer. The remote communication receiving module receives stress information sent by the remote communication transmitting module, the displayer displays image information collected by the three-dimensional laser scanner, and the main controller receives and processes the stress information and the scanned image information. The invention further provides a survey method for the remote survey system for the tunnel construction site. Not only can the actual grouting amount required in a tunnel be surveyed remotely, but also the stress change process in the tunnel can be remotely monitored, and the tunnel surveying work is more convenient.

Problems solved by technology

With the expansion of urban traffic scale, the environment of underground tunnel facilities is becoming more and more complex. Some tunnel facilities have mountains or large building components above them, and there may even be other tunnels, mountains or large building components above or below the tunnels. The area below and the overlapping area between the tunnels are high-risk areas, prone to disasters such as settlement, collapse, and displacement. Therefore, for the construction of the tunnel, real-time on-site surveys are extremely dangerous. In order to prevent disasters and avoid danger, It is not only necessary to improve the safety and automation of survey work, but also to carry out round-the-clock uninterrupted monitoring of tunnels in high-risk areas. Due to low efficiency and low precision, there is often a large deviation from the actual demand, and the real tunnel interior scene cannot be simulated, and the accurate calculation result of the grouting amount cannot be obtained; for remote monitoring of tunnel surveys, high-precision measuring robots are generally used. The deformation of the tunnel structure is monitored. However, the cost of measuring robots is high. In actual projects, measuring robots are generally deployed only in key areas with a small range, resulting in limited monitoring areas. Moreover, due to the precise structure and complex technology of measuring robots, the later maintenance costs are also high. very amazing
