Description
Technical field
The present invention relates to railway tunnel work construction technology, specifically a kind of tunnel davit flange angle measurement tool and
Utilize the davit flange angle measurement method of the tool.
Background technique
Railway tunnel construction is with a varied topography, and the different concrete conditions faced have exceeded theory setting, such as Lan Yu Railway
Lanzhou to Guangyuan section is by way of 13 sweet, Shan, Chuan San province counties (area), and (its Bridge 126/length 74 is public for 501 kilometers of positive line length
In, major long tunnel 67/350 kilometers of length), tunnel accounting about 70%.This line tunnel cross-section mainly has three categories: double track tunnel is disconnected
Face, the ellipse hole section of single-track tunnel, single-track tunnel TBM (complete-section tunnel boring machine) section, on this basis, and have subdivision, such as
WEST QINLING single-track tunnel section just has as many as 28 kinds.Single-track tunnel contact net davit is influenced by headroom and section, unlike two-wire tunnel
Road contact net davit is arranged in tunnel top, and davit flange angle drift angle is smaller, smaller unqualified adjustment workload；And single line
Tunnel overhead contact davit is then all arranged in tunnel-side, causes flange angle drift angle larger, single-track tunnel section such as Fig. 5 institute
Show, anchor arm drift angle of casting anchor also is such.In addition, davit flange bottom plate is that disposable welding sizing produces during manufacturing
Product can not be changed, if flange angle measurement inaccuracy, will cause greatly difficult and wave to construction and installation and subsequent adjustment
Take.
During traditional construction, the drift angle of davit flange bottom plate is determined and mainly uses following method:
(1) laser range finder mensuration
DATA REASONING is carried out using laser range finder and trigonometric function converts, and tunnel davit flange tilt angle is by vertical line
It road direction and determines along outermost two bolt-center distances of line direction.Assuming that single-track tunnel section is ellipse knot
Structure, because of the code requirement of davit side limit and headroom, contact net davit can be only installed at tunnel-side, then davit flange must
There is a tilt angle could be on oval inclined-plane, i.e., davit flange is slightly lower close to answering for tunnel-side side, close to bracket side
It answers slightly higher.The vertical range of a certain bolt of upper row to rail level is first measured using laser range finder, such as measurement distance is 7452mm；Again
The vertical range of a certain bolt of lower row to rail level is measured, such as measurement distance is 7158mm.Davit flange is mounted on tunnel-side two
The distance of bolt is 350mm, and arranging the height difference between bolt up and down is 7452-7158=294mm.Thus it can calculate, flange inclination
Angle are as follows: 32.8 ° of ≈ of θ=acrcos (294/350).
(2) standard section drawing mensuration
It is linked up with designing unit's (or unit before standing) and the standard two for obtaining tunnel cross-section serves as a contrast cross-section diagram, and according to contact net
Relevant design parameter, such as side limit, conductor height, structure height parameter carry out dimensional standard using CAD cross-section diagram, into
And determine the davit flange tilt angle of theoretical parameter.
The relative measurement error of the above-mentioned 2 kinds of methods enumerated is all larger and applicability is not high, and the 1st kind of method uses Laser Measuring
The applicability of distance meter measurement angle is not high, needs professional technician that mapping is gone to calculate, occupies technical staff's a large amount of time,
Low efficiency and data acquisition errors rate is big, is limited greatly by rail adjustment；2nd kind of method uses standard section figure, theoretical parameter
Etc. data simulated on CAD diagram and measure angle, because the randomness of construction parameter is big, cause the error rate of nominal tilt angle big
And only technical staff knows algorithm, the purpose that total involvement construction is not achieved can not when flange tilt angle model is excessive yet
Quickly check, causes construction site to install complete confusion, and rework rate is high.
In conclusion only being rested on unified type in conventional method for the determination of davit flange tilt angle, such as singly
The tunnel oval-shaped hole section davit flange tilt angle of line is unified for 33 °, and single-track tunnel TBM section davit flange tilt angle is unified
It is 25 °, double track tunnel section davit flange tilt angle is unified for 5 ° etc..Once there is section variation or construction ginseng in construction site
Number error, original standard davit flange tilt angle is just no longer suitable or is clogged using gasket or is purchased again, takes
When take material it is costly.It is measured convenient for construction personnel for this purpose, innovation is a kind of and promotes the high angle measurement tool gesture of applicability
It must go.

The back side of flange angle measurement tool is directly aligned davit flange 16 by climbing tools by second step, operator
Profile fits to 16 outside of davit flange, and the cast-in fixing bolt on davit flange is pierced by flange anchor hole 1, keeps flange analog board 2
It is parallel with davit flange.In general, only need to vertically apply pressure to flange analog board 2.
Third step, the stabilization for keeping flange analog board 2, the measurement arm 9 of angle measuring scale 3 is opened, angle measurement is passed through
Detector perpendicularity detector 6 or levelness detector 5 on ruler 3 detect and keep measurement arm either vertically or horizontally, directly read angle
Angular readings shown by display device 18 and record.
For measuring the tool of centralized procurement, the button of function button group is pressed when measuring and stablizing, is set in angle measuring scale 3
Processor, which is triggered, to be stored in real-time measurement values and time data to nonvolatile storage, and can be controlled later by button will
Corresponding data carries out display or module is sent to other equipment by wireless communication.
Whole operation process simple, intuitive, use easy to spread and be not limited to technical staff and expend time, budget and high
Expensive professional measuring tool measures, but measurement result is efficient and accurate.Simple and effective intention is exactly worth construction work
What journey and technical field were promoted.
