Abstract
A kind of scalable horizon rule measured for tunnel super large shield duct piece, effectively to solve big shield driving rings survey horizon rule and long carry, awkward technical barrier.It includes that longitudinal both sides have a main scale of shift sleeve structure, and be installed in shift sleeve structure left side pair chi, right side pair chi, the middle part of described main scale is fixedly installed prism centring screw bolt and long level(l)ing bubble.
Description
Technical field
This utility model relates to railway tunnel structure, a kind of scalable level measured for tunnel super large shield duct piece
Chi, mainly solves the horizon rule length when super large shield duct piece is relatively large in diameter long, carries, inconvenient problem with use.
Background technology
In metro shield tunneling process, correct in order to ensure position, section of jurisdiction, need real-time monitoring tubular sheet attitude.Owing to entering
The section of jurisdiction of row assembly is all through checking qualified section of jurisdiction, usually assumes that assembled good section of jurisdiction is a proper circle, real by total powerstation
The centre coordinate of test tube sheet and elevation are as the foundation of section of jurisdiction position control.
Being placed on the inverted arch of section of jurisdiction by horizon rule, level(l)ing bubble is in center condition, by measuring position, horizon rule midpoint
Set high journey, just can determine that the deviation between design attitude and actual attitude.
The section of jurisdiction size of super large shield, much larger than the size of conventional section of jurisdiction, which results in corresponding horizon rule length ratio
Conventional levels chi to be grown.Such horizon rule carries, it is very inconvenient to use.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for stretching that tunnel super large shield duct piece is measured
Shrink leveling ruler, effectively to solve big shield driving rings survey horizon rule and long carry, awkward technical barrier.
It is as follows that this utility model solves the technical scheme that this technical problem used:
A kind of scalable horizon rule measured for tunnel super large shield duct piece of this utility model, is characterized in that: it includes
Longitudinal both sides have a main scale of shift sleeve structure, and be installed in shift sleeve structure left side pair chi, right side pair chi, described main scale
Middle part be fixedly installed prism centring screw bolt and long level(l)ing bubble.
Effect of the present utility model is, horizon rule longitudinal direction two ends are scalable, and level can be greatly shortened under non-working condition
The length of chi, it is simple to carry and use.
Accompanying drawing explanation
This specification includes following two width accompanying drawings:
Fig. 1 is the structural representation of a kind of scalable horizon rule measured for tunnel super large shield duct piece of this utility model
Figure；
Fig. 2 is the profile of line A-A along Fig. 1；
Component shown in figure, position and corresponding labelling: main scale 10, prism centring screw bolt 11, long level(l)ing bubble 12, stifled
13, left side pair chi 21, right side pair chi 22.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
With reference to Fig. 1, a kind of scalable horizon rule measured for tunnel super large shield duct piece of the present utility model includes indulging
There is the main scale 10 of shift sleeve structure to both sides, and be installed in shift sleeve structure left side pair chi 21, right side pair chi 22.Described
The middle part of main scale 10 is fixedly installed prism centring screw bolt 11 and long level(l)ing bubble 12.When long level(l)ing bubble 12 is used for ensureing work
Ruler is in level, when preparing to measure, prism inserts centring screw bolt 11.The left side pair chi at horizon rule longitudinal direction two ends
21, right side pair chi 22 can stretch relative to main scale 10, the length of horizon rule can be greatly shortened, it is simple to carry under non-working condition
And use.
Described shift sleeve structure can be to use various structures form.In Fig. 1 shows embodiment, the middle part of described main scale 10 is
Solid construction, shift sleeve structure is the gathering sill outside solid construction longitudinal direction both sides.The outer end of described shift sleeve structure is provided with and left side
The plug 13 that the inner block of secondary chi 21, right side pair chi 22 is corresponding.
Generally, main scale 10, left side pair chi 21, right side pair chi 22 use aluminum alloy material, horizon rule total length >=5 meter), receive
A length of≤3.4m after contracting), a length of 2.5m of mid portion, left-right parts clear length >=1.25m.
The above this utility model that simply explains through diagrams a kind of for tunnel super large shield duct piece measure scalable
Some principles of horizon rule, are not intended to be confined to by this utility model in shown and described concrete structure and the scope of application,
Therefore every corresponding amendment being likely utilized and equivalent, belong to the apllied the scope of the claims of this utility model.
