Description
Technical field
Railway tunnel work construction technology is the utility model is related to, specifically a kind of tunnel davit flange angular surveying work
Tool.
Background technology
Railway tunnel construction is with a varied topography, and the different concrete conditions faced are beyond theory setting, such as Lan Yu Railway
Lanzhou to Guangyuan section is by way of 13 sweet, Shan, Chuan San provinces counties (area), and (its Bridge 126/length 74 is public for positive 501 kilometers of line length
In, major long tunnel 67/350 kilometers of length), tunnel accounting about 70%.This line tunnel cross-section mainly has three major types：Double track tunnel breaks
Face, the ellipse hole section of single-track tunnel, single-track tunnel TBM (complete-section tunnel boring machine) section, on this basis, have subdivision, such as again
WEST QINLING single-track tunnel section just has as many as 28 kinds.Single-track tunnel contact net davit is influenceed 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, also smaller even if 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 institutes
Show, anchor arm drift angle of casting anchor also is such.In addition, davit flange bottom plate is disposable welding sizing production during manufacturing
It product, can not change, if flange angular surveying is inaccurate, greatly difficult and wave will be caused to construction and installation and follow-up adjustment
Take.
During traditional construction, the drift angle of davit flange bottom plate is determined mainly to use following method：
(1) laser range finder mensuration
DATA REASONING and trigonometric function conversion are carried out using laser range finder, tunnel davit flange angle of inclination is by vertical line
Road direction and determine along outermost two bolt-center distances of line direction.Assuming that single-track tunnel section is tied for ellipse
Structure, because of the code requirement of davit side gauge and headroom, contact net davit can be only installed at tunnel-side, then davit flange must
There is the angle of inclination could to be mounted on oval inclined-plane, i.e., davit flange close to tunnel-side side should be lower slightly, close to bracket side
Should be slightly higher.It is 7452mm that a certain bolt of upper row to the vertical range of rail level, such as measurement distance is first measured using laser range finder；Again
It is 7158mm to measure a certain bolt of lower row to the vertical range of rail level, such as measurement distance.Davit flange is arranged on tunnel-side two
The distance of bolt is 350mm, and the discrepancy in elevation arranged up and down between bolt is 7452-7158=294mm.Thus can calculate, flange tilts
Angle be：32.8 ° of θ=acrcos (294/350) ≈.
(2) standard section drawing mensuration
The standard two linked up with designing unit's (or unit before station) and obtain tunnel cross-section serves as a contrast sectional drawing, and according to contact net
Relevant design parameter, such as side gauge, conductor height, structure height parameter, dimensional standard is carried out using CAD sectional drawings, is entered
And determine the davit flange angle of inclination 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 it is not high, it is necessary to professional and technical personnel go mapping calculate, occupy technical staff's substantial amounts of time,
Efficiency is low and data acquisition errors rate is big, is limited greatly by rail adjustment；2nd kind of method is using standard section figure, theoretical parameter
Etc. data, analogue measurement goes out angle on CAD diagram, because the randomness of construction parameter is big, causes the error rate of nominal tilt angle big
And only technical staff knows algorithm, do not reach the purpose of total involvement construction, when flange angle of inclination model is excessive, can not yet
Quick check, causes job site to install complete confusion, and rework rate is high.
In summary, the determination in conventional method for davit flange angle of inclination is only rested on unified type, such as singly
The tunnel oval-shaped hole section davit flange angle of inclination of line is unified for 33 °, and single-track tunnel TBM section davit flanges angle of inclination is unified
For 25 °, double track tunnel section davit flange angle of inclination is unified for 5 ° etc..Once there is section variation or construction ginseng in job site
Number error, original standard davit flange angle of inclination is just no longer suitable, or being clogged using pad, or purchasing again, takes
When take material it is costly.It is easy to workmen to measure therefore, innovation utility model is a kind of and promotes the high angular surveying work of applicability
It is imperative to have.
