Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The present embodiment is discussed in detail by taking the monitoring of the clearance convergence of tunnel and shield duct piece as an example below uses forced centering
The method that mode enters row distance monitoring.
As Figure 1-Figure 2, the method that row distance monitoring is entered with forced centering mode of the present embodiment is applied to tunnel
It is used to include forced centering apparatus and laser range finder 3 apart from monitoring device in the embodiment of clearance convergence monitoring, wherein
Forced centering apparatus includes structure snd size all same or close permanent magnet 1 and permanent magnet 22.Preferably, this implementation
In example, permanent magnet one and permanent magnet two use structure snd size specification identical cylindrical-shaped structure, wherein permanent magnet one and permanent magnetism
A diameter of φ 15mm~φ 30mm of iron two, thickness are 2mm~5mm.
It is generally that permanent magnet 1 is pre-buried or by way of bar planting gluing knot be fixed on tunnel in clearance convergence monitoring process
On road wall.Wherein permanent magnet 22 is fixed on the tail end of laser range finder 3, is not elaborated herein as fixed mode, only
It need to ensure that the axis of permanent magnet 22 overlaps or parallel with the laser beam that laser range finder 3 is sent.In addition, the permanent magnetism
Side and permanent magnet two 2 side magnetic pole away from laser range finder 3 of the iron 1 away from tunnel wall is on the contrary, can mutual magnetic.As
It is preferred that in order to prevent that permanent magnet 1 and permanent magnet 22 are too big in the impulsive force close to each other to when being attached together, generally exist
Dottle pin 4 is provided between permanent magnet one and permanent magnet two, plays a part of protecting permanent magnet one and permanent magnet two, the tool of the dottle pin 4
Body structure does not do sole limitation herein with form, can be arranged on the surface of permanent magnet one, can also be arranged at permanent magnet two
Surface, or the wall of laser range finder tail end after installation permanent magnet two.
It should be noted that when the cylindrical permanent magnet of two block structures and size all same is mutually adsorbed, due to the magnetic line of force
The characteristic of distribution, it is automatic forced centering, i.e., two blocks of columned permanent magnets are necessarily coaxial, and this is that permanent magnet has in itself
Some characteristics, do not elaborate herein.The purpose of the application is, the characteristic of this automatic forced centering is applied into tunnel
Convergence monitoring in.
