Make cumbersome problem.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is to provide a kind of suspension bridge anchoring system
System measuring device, comprising:
Three forced centering piers, are arranged in the cap beam in the front of anchor system；
Total station is disposed therein on the forced centering pier；
Reflector plate is arranged in the center of two-beam anchor pole, the center suitable for reading of single beam anchor pole and the center Xia Kou, rear anchor beam direction and dissipates
The center of four angle points in rope point face and the rear anchor beam and the two-beam anchor pole and single beam tieback connector.
In another preferred embodiment, the line of three forced centering piers surrounds acute angle isosceles triangle.
In another preferred embodiment, the two-beam anchor pole includes vertical bar and several cross bars, each cross bar pair
Claim to be arranged on the vertical bar, the list beam anchor pole is in rectangle.
In another preferred embodiment, the reflector plate uses acrylic material.
Compared with prior art, the utility model buries in the cap beam immediately ahead of anchor system before anchor system installation
If forced centering pier, using the coordinate of total station and reflector plate acquisition characteristics point, using reflector plate as measurement observation mark, rear anchor
When beam, two-beam anchor pole and single beam anchor pole adjustment, reflector plate is pasted onto the position for needing to observe, can directly and quickly be measured
The deviation of measuring point effectively eliminates the precision that measurement has greatly been turned up manually to the installation of characteristic point and measurement error；It avoids
Operating personnel is climbed up and down to the security risk generated, operate it is also more convenient, it is simple and convenient；Shorten measurement observation
Time greatly increases the efficiency of anchor system mounting and adjusting.
Detailed description of the invention
Fig. 1 is the anchor system construction infilling control point arrangement schematic diagram in the utility model；
Fig. 2 is the anchor system construction coordinate system in the utility model；
Fig. 3 is the two-beam anchor pole observation point arrangement schematic diagram in the utility model；

Specific embodiment
The utility model provides a kind of suspension bridge anchor system measuring device, can eliminate measurement error, and it is convenient to operate.
The utility model is described in detail with specific embodiment with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of suspension bridge anchor system measuring device provided by the utility model, including forced centering pier,
Total station and reflector plate, forced centering pier are three, are arranged in the cap beam in the front of anchor system；Total station is arranged at it
In on a forced centering pier；Reflector plate be arranged in the center of two-beam anchor pole, the center suitable for reading of single beam anchor pole and the center Xia Kou, after
Anchor beam is towards four angle points for dissipating rope point face, and the center of anchor beam and two-beam anchor pole, single beam tieback connector afterwards.
Preferably, the line of three forced centering piers surrounds acute angle isosceles triangle, and total station is arranged about isosceles three
On symmetrical two angle points in angular center.
Preferably, two-beam anchor pole includes vertical bar and several cross bars, and each cross bar is symmetricly set on vertical bar, and single beam anchor pole is in
Rectangle.
Preferably, the reflector plate uses acrylic material.Acrylic is called PMMA or organic glass, is originated from English
Acrylic (acrylic plastics), chemical name are polymethyl methacrylate, are a kind of exploitation important plasticity high scores earlier
Sub- material has the preferable transparency, chemical stability and weatherability, easy dyeing, easy processing, attractive appearance, in construction industry
Extensive application.Organic glass product can be generally divided into casting plate, extrusion board and moulding compound.
The measurement method carried out using the utility model, comprising the following steps:
S1. three forced centering observation piers are buried in the cap beam immediately ahead of anchor system, total station sets up wherein one
In a forced centering observation pier；Control net repetition measurement when, by the location point of these three forced centering observation piers together with whole net repetition measurement
With comment poor calculating.
S2. four angle points, rear anchor beam and the two-beam anchor pole in rope point face, the center of single beam tieback connector are dissipated in rear anchor beam direction
Stick reflector plate；
S3. reflector plate is sticked at the center at the center of two-beam anchor pole, the suitable for reading and lower mouth in single beam anchor pole top；Such as Fig. 3 and Fig. 4
It is shown, the center 4 that reflector plate pastes two-beam anchor pole is observed；Reflector plate pastes 5 He of top center of single beam anchor pole
Bottom centre 6 takes the average value of two o'clock and the centre coordinate for single beam anchor pole.
S4. anchor center is set as X-direction to scattered rope point after, establishes the coordinate system of anchor system；When construction survey,
It can intuitively find out the deviation of rear anchor beam and anchor pole longitudinally, laterally with elevation direction.
S5. utilize coordinate system, reflector plate position, that is, characteristic point of anchor system is observed, after adjustment anchor beam and
Anchor pole is to design position.
Preferably, the line of three forced centering piers surrounds acute angle isosceles triangle, as shown in Figure 1, anchor system is installed
When measurement, total station is erected on the first forced centering pier 1 or the second forced centering pier 2 in Fig. 1, the pressure of backsight third is returned
Heart pier 3.
Wherein, in step s 2, by the patch on top, downward, low side patch respectively translates an identical size upwards,
Calculate the coordinate of corresponding point.Not clearly demarcated enough in four corner angle of rear anchor beam, reflector plate is difficult to paste the feelings of theoretical position
Under condition, the operation of this mobile symmetrical size is more simple, while also can guarantee accuracy.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn that the enlightenments in the utility model
Under the structure change made, it is all that there is same or similar technical solution with the utility model, each fall within the utility model
Within protection scope.
