Description
Technical field
The utility model relates to Urban Rail Transit Projects, more particularly, to a kind of subway segment attitude measurement ruler.
Background technique
With the acceleration of economic rapid development and urbanization process, the Urban Rail Transit Project in China is gradually
Into climax, in Construction of Urban Rail Traffic, shield method tunnel construction has become because its is highly-safe, speed of application is fast
The main construction method of each urban track traffic constructing tunnel.It is existing using shield method carry out subway work when, subway segment
The measurement of posture, which is utilized on aluminum alloy square tube, pastes reflective sticker, then is bundled on horizontal ruler, levelling using horizontal ruler,
It is measured in conjunction with artificially lighting method；But due to underground backlight, dark, therefore reflective sticker receive light beam very
Difference, and aluminum alloy square tube and horizontal ruler combination mode easily lead to section of jurisdiction contact point serious wear, cause total station to acquire
Data error it is larger, section of jurisdiction acquire data it is inaccurate；In addition, existing simple combination is unsatisfactory for the rule of measurement instrument
It is fixed, do not meet code requirement.
Summary of the invention
The utility model aim is to provide that a kind of structure is simple, uses easy subway segment attitude measurement ruler.
To achieve the above object, the utility model can take following technical proposals:
Subway segment attitude measurement ruler described in the utility model, the horizontal ruler including having levelling tube, in the level
Installation chamber is offered in the middle part of the front side wall of ruler, is installed with round prism at the center of the installation chamber, is located at the round prism
It is provided with annular reflective sticker on the installation chamber inner wall of front side, the installation cavity between the reflective sticker and the round prism
Interior is distributed along the circumference with several headlamps；Charging hole, which is provided with, in the installation cavity room on rear side of the round prism extends level
The lighting lamp power of ruler rear wall is provided with power switch on the side wall of the horizontal ruler.
The both ends of the horizontal ruler are provided with anti-wear end block.
Handle is provided on the roof of the horizontal ruler.
The utility model advantage is that structure is simple, installs and using easy.Level can be easily leveled by levelling tube
Ruler opens headlamp later, and the brightness of round prism front is improved by the reflected light of annular reflective sticker, enables total station
Not by underground backlight, the influence of dark clearly, accurately acquires data, it is ensured that total station acquisition data do not occur compared with
Big error improves measurement accuracy, so that the measurement instrument is met regulation, meets code requirement；In addition, entire measuring scale structure is small
Ingeniously, easy to carry, stable structure can reduce personnel's investment when construction survey, greatly improve the efficiency of construction survey.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the portion A enlarged drawing in Fig. 2.
Specific embodiment
As shown in Figure 1-3, subway segment attitude measurement ruler described in the utility model, the level including having levelling tube 1
Ruler 2, i.e., existing common horizontal ruler on the market；Installation chamber 3 is offered in the middle part of the front side wall of horizontal ruler 2, installation chamber 3
It is installed with round prism 4 at center, annular reflective sticker 5 is provided on 3 inner wall of installation chamber of 4 front side of circle prism, anti-
Several headlamps 6 are distributed along the circumference in installation chamber 3 between light patch 5 and circle prism 4, headlamp 6 is before circle prism 4
The circumferential direction of side outer edge uniformly distributed 4；Charging hole 7, which is provided with, in the installation chamber 3 of 4 rear side of circle prism extends horizontal ruler
The lighting lamp power 8 of 2 rear walls, mains lighting supply 8 is the power supply of headlamp 6, and can pass through the charging hole on 2 rear wall of horizontal ruler
7 carry out electric power storage, and the power switch 9 that control headlamp 6 opens or closes is provided on the side wall of horizontal ruler 2.
It is collided with or is worn to prevent the both ends when using and placing of horizontal ruler 2 from contacting with subway segment, in horizontal ruler 2
Both ends be provided with anti-wear end block 10, anti-wear end block 10 can be the angle steel for being directly fixed on 2 both ends of horizontal ruler, improve end
Rigidity and wear resistance；In addition, handle 11 can also be arranged on the roof of horizontal ruler 2 for convenience of carrying.
In use, subway segment attitude measurement ruler described in the utility model to be placed on to the spelling of two panels subway segment first
Place is met, left and right sides each one, manually adjusts horizontal ruler 2 according to levelling tube 1, keeps its holding horizontal；Power switch is pressed later
9, headlamp 6 is opened, under the reflection light action of annular reflective sticker 5, is illuminated the front of round prism 4；It measures at this time
Personnel can be using total station come to director circle prism 4, and carries out the measurement of subway segment posture, it is ensured that the data of total station acquisition
There is not large error, improves measurement accuracy.
