Description
Technical Field
The invention relates to a railway tunnel engineering construction technology, in particular to a tunnel hanging column flange angle measuring tool and a hanging column flange angle measuring method using the same.
Background
The construction topography of the railway tunnel is complex, and the faced different specific conditions exceed theoretical settings, for example, 13 counties (regions) from lan to guangYuan in lan, shan and Chuan three provinces, the length of the positive line is 501 km (wherein the bridge 126 seats/74 km long and the tunnel 67 seats/350 km long), and the tunnel accounts for about 70%. The section of the tunnel of the line mainly has three main categories: the double-line tunnel section, the single-line tunnel elliptical section and the single-line tunnel TBM (full section tunnel boring machine) section are subdivided, and the number of single-line tunnel sections is as large as 28 in the SiQinling province. Unlike the double-line tunnel overhead contact system overhead posts, which are arranged on the tunnel roof, the single-line tunnel overhead contact system overhead posts are affected by the clearance and the section, and the flange angle deflection of the overhead posts is smaller, so that the workload is smaller even if the overhead posts are unqualified; the single-line tunnel contact net hanging posts are all arranged on the side wall of the tunnel, so that the angle deflection angle of the flange is larger, and the single-line tunnel section is shown in fig. 5, so that the deflection angle of the anchor arm is also the same. In addition, the lifting column flange bottom plate is a one-time welding and shaping product in the production and manufacturing process, cannot be changed, and can cause great difficulty and waste for construction and installation and subsequent adjustment if the flange angle measurement is inaccurate.
In the traditional construction process, the deflection angle of the bottom plate of the suspension column flange is determined by mainly adopting the following method:
(1) Laser range finder measuring method
And (3) carrying out data measurement by using a laser range finder and converting a trigonometric function, wherein the inclination angle of the tunnel hanging column flange is determined by the center distances of the two outermost bolts in the vertical line direction and the line direction. The section of the single-line tunnel is in an oval structure, and the contact net hanging column can only be arranged on the side wall of the tunnel due to the standard requirements of the side limit and the clearance of the hanging column, so that the hanging column flange can be arranged on an oval inclined plane only by a certain inclination angle, namely the hanging column flange is slightly lower near the side wall of the tunnel and is slightly higher near the side of the cantilever. Firstly measuring the vertical distance between a certain bolt of the upper row and the rail surface by using a laser range finder, and if the measured distance is 7452mm; the vertical distance from a certain bolt of the lower row to the rail surface is measured, and the measured distance is 7158mm. The distance between the two bolts of the hanging column flange arranged on the side wall of the tunnel is 350mm, and the height difference between the upper row of bolts and the lower row of bolts is 7452-7158=294 mm. From this, it can be calculated that the flange is inclined at the following angle: θ=acrcoss (294/350) ≡32.8 °.
(2) Standard section drawing measuring method
And (3) communicating with a design unit (or a pre-station unit) and obtaining a standard two-lining section diagram of the tunnel section, and carrying out size standard by utilizing the CAD section diagram according to related design parameters of the overhead contact system, such as side limit, wire height, structure height and the like, so as to determine the inclination angle of the suspension column flange of the theoretical parameter.
The 2 methods are larger in relative measurement error and low in applicability, the 1 st method is low in applicability of measuring angles by using a laser range finder, a great amount of time is occupied for technical staff to carry out mapping calculation, the efficiency is low, the data acquisition error rate is large, and the method is extremely limited by steel rail adjustment; the 2 nd method adopts data such as a standard section view, theoretical parameters and the like to simulate and measure angles on a CAD graph, and because of high randomness of construction parameters, the error rate of the standard inclination angle is high, only technicians know algorithms, the aim of participating in construction of the whole person cannot be achieved, and when the model of the inclination angle of the flange is too many, quick review cannot be performed, so that a piece of confusion is caused in installation of a construction site, and the rework rate is extremely high.
In summary, in the conventional method, the determination of the inclination angle of the suspension column flange is only performed on the unified type, for example, the inclination angle of the suspension column flange on the section of the single-line tunnel elliptical hole is unified to 33 °, the inclination angle of the suspension column flange on the section of the single-line tunnel TBM is unified to 25 °, the inclination angle of the suspension column flange on the section of the double-line tunnel is unified to 5 °. Once the section change or the construction parameter error occurs in the construction site, the inclination angle of the original standard hanging column flange is not suitable any more, or a gasket is adopted for filling, or the construction site is purchased again, so that the time, the material and the cost are wasted. Therefore, the novel angle measuring tool which is convenient for constructors to measure and has high popularization applicability is imperative.
