The tunnel convergence laser monitoring system can be installed quickly and conveniently, has less construction interference and high test speed and measuring accuracy, is portable, and can monitor the convergence of the tunnel and the underground engineering in real time.
Description
Technical field
The utility model relates to a kind of tunnel convergence monitoring system, particularly a kind of tunnel convergence laser monitoring system.
Background technology
The periphery convergence is 2 displacement relative variations in the line direction of tunnel perimeter, i.e. 2 absolute displacements change sum, convergence monitoring also as railway tunnel, vcehicular tunnel monitoring measurement technical regulation (TB10121-2007 J721-2007) regulation one of must the survey project, convergence Monitoring Data and as the main foundation of interpretation adjoining rock stability and supporting effect.
The convergence baseline of tunnel and underground works monitoring at present mainly measures with the mechanical type convergence gauge, the mechanical type convergence gauge, be that steel ruler, tension equipment, dial gauge are traditional instruments, its test philosophy is that steel ruler, weight, spring with tensioning is as the media that transmits displacement, with the reading device of dial gauge as displacement.This has inevitably brought two kinds of defectives, and the temperature error of one steel ruler is big and along with headroom strengthens and linear increase, though the on-the-spot temperature correction poor effect of having done; Disturb normal construction when secondly doing to measure owing to steel ruler.
The utility model content
In order to overcome the deficiency of existing tunnel convergence measurement mechanism, the utility model provides a kind of tunnel convergence laser monitoring system.
The technical scheme that its technical matters that solves the utility model adopts is:
Tunnel convergence laser monitoring system comprises laser ranging system, reflective marker body; Laser ranging system is made up of laser ranging module, bearing, base, measurement button; The laser ranging module is installed on the base by bearing, and base is fixed on the pre-buried measuring point in tunnel by joint, and the laser ranging module connects by the control cable measures button.
The plate shaped attribute block of reflective marker body is applicable to convergence monitoring situation between horizontal measuring point, and many ribs centrum is applicable to convergence monitoring between multi-measuring point simultaneously, and only the line direction is provided with reflectance coating between measuring point.Make that line is vertical substantially between reflection face and the measuring point of measuring point, detachable after the reflective marker bulk measurement, avoid the damage in the work progress.
Laser ranging module employing laser transmitting-receiving integrated module measures the distance between two measuring points, and the measuring distance scope is 5～30m.Support manual measurement pattern and auto-measuring pattern, when adopting manual measurement pattern, realize measuring button and separate that equipment does not have slight jitter or moves when guaranteeing to measure with the laser ranging module; When adopting the auto-measuring pattern, frequency adjustable.
To the singularity of point according to tunnel and underground works convergence monitoring, the measuring point spacing range is 5～30m, and laser only need carry out carrying out on plane and the facade angle coarse adjustment, locking, finely tune to reach accurately to point point apparatus.
The beneficial effects of the utility model are, and are quick for installation, and construction is disturbed few, and test speed is fast, and measuring accuracy height, easy to carry can realize that also tunnel and underground works convergent monitor in real time.
