Row unwrapping wire positions, and height is required to operating personnel, and time of measuring is long, and equipment investment is high, is difficult to operate under dim equal complex environments,
It is influenced by surrounding enviroment.Especially tunnel diameter is smaller, the poor operation side of construction environment, and unwrapping wire is carried out using total powerstation
It positions particularly inconvenient.
Invention content
The purpose of this utility model is that consider the above problem and a kind of canal axes measuring device is provided, the utility model
Equipment investment is reduced, operating personnel are required low, the used time is short, and easy to operate, time saving and energy saving, convenient and practical.
The technical solution of the utility model is：The canal axes measuring device of the utility model, include the first calibrating jig,
Second calibrating jig, first laser transmitter, second laser transmitter, graduated scale, fixing bracket, wherein the first calibrating jig is installed in
The outside of tunnel, the second calibrating jig are installed in the outside of tunnel, fixing bracket be installed in the first calibrating jig and the second calibrating jig it
Between, first laser transmitter and second laser transmitter are respectively by being installed in the top of the first calibrating jig by the first connector
And lower part, graduated scale are fixed on the top of the second calibrating jig by the second connector.
The canal axes measuring device of the utility model need to only use total powerstation or GPS to carry out one-time positioning, it is interim into
Row review can achieve the purpose that check canal axes positioning and hole diameter, and of less demanding to tester technical merit,
Vast majority of people can operate, and easy to operate, and opening laser beam device can intuitively reflect that construction quality whether there is and ask
Topic.The utility model makes simple, reduces equipment investment, requires operating personnel low, and the used time is short, and the reflection of operation achievement is direct,
It is same operable under dim equal complex environments, it is not influenced substantially by surrounding enviroment.The utility model is that one kind greatling save survey
Measure time, easy to operate, time saving and energy saving, lower-cost convenient and practical canal axes measuring device.
Description of the drawings

Fig. 2 is the structural schematic diagram of the first calibrating jig of the utility model and the second calibrating jig.
Specific implementation mode
Embodiment：
The structural schematic diagram of the utility model is as shown in Figure 1, 2, the canal axes measuring device of the utility model, including
There is the first calibrating jig 1, the second calibrating jig 7, first laser transmitter 2, second laser transmitter 3, connector 4, graduated scale 5, consolidate
Fixed rack 6, wherein the first calibrating jig 1 is installed in the outside of tunnel, the second calibrating jig 7 is installed on the outside of tunnel, and fixing bracket 6 fills
It is located between the first calibrating jig 1 and the second calibrating jig 7, first laser transmitter 2 and second laser transmitter 3 are respectively by passing through
First connector 4 is installed in the top and lower part of the first calibrating jig 1, and graduated scale 5 is fixed on the second scale by the second connector 8
The top of frame 7.The installation site of second calibrating jig 7 can be placed on the position for wanting testing to check, first laser transmitter 2 as needed
Mounting height it is consistent with tunnel radius, the mounting height of second laser transmitter 3 is random, without departing from the height of fixing bracket 6
.
Above-mentioned graduated scale 5 is fixed on the top of the second calibrating jig 7, and effect can be calculated according to the length of graduated scale 5
Go out tunnel radius.
In the present embodiment, above-mentioned first laser transmitter 2 and second laser transmitter 3 are pen type laser emitters.
In the present embodiment, above-mentioned first calibrating jig 1, the second calibrating jig 7 are the liftable scale holders that can adjust height.
In the present embodiment, above-mentioned fixing bracket 6 is timber, or any other rod-shaped material, timber are more cheap.
In the present embodiment, above-mentioned graduated scale 5 is retractable graduated scale, such as spirit level Sopwith staff, the structure with lifting support
Almost.
In the present embodiment, 4 and second connector 8 of above-mentioned first connector is bolt.
In the present embodiment, 4 and second connector 8 of above-mentioned first connector is rotatable bolt.Bolt, which is tightened, then can not
Rotation, bolt is not tightened i.e. rotatable.
The operation principle of the utility model is：Before tunnel construction, tunnel is found out using total powerstation, theodolite or GPS system
Two points on axis outside hole, the position of two points can arbitrarily be chosen, but reconnaissance is required to be located on axis.Points outside can for fixation
Adjust the first calibrating jig 1 of lifting, interior side point for the fixed fixing bracket 6 checked, the second calibrating jig 7 of adjustable up-down and
The tool that flexible graduated scale 5 is checked as required measuring point.The first laser on 1 top of the first calibrating jig of adjustable up-down is sent out
Emitter 2 sends out ray and selects the level standard point that canal axes and hole diameter measure, and second laser transmitter 3 below is radiated at school
On the fixing bracket 6 of core, you can check the axis direction of tunnel.Because 2 points determine straight line, second laser transmitter 3
Ray is perpendicular to fixing bracket 6, and first laser transmitter 2 and 3 direction of second laser transmitter are consistent, second laser transmitter
3 ray is penetrated on fixing bracket 6, because fixing bracket 6 is on axis, therefore can ensure penetrating for the injection of first laser transmitter 2
Line is canal axes.
