Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention, by selecting two control points on arch rib upper and lower string pipe lateral edges line, when its coordinate theoretical value is consistent with actual comparison, to accurately positioning between rib-lifting section, assembled, guarantees that each sections locus of arch rib and arch conform to design.
As shown in Figure 1, the construction arch axis coefficient of tubular arch is second-degree parabola to steel pipe arch bridge.Due to instrument cannot be set up on the arch of arch rib, but arch rib string pipe lateral edges line (determine in produce in factory process at steel tube arch rib by lateral edges line, and identify with dotting punch) fix with the relative position of arch, so two control points first can be selected on arch rib upper and lower string pipe upper port place lateral edges line, locate arch rib by the method contrasting two control point coordinate theoretical values and actual value.
Fig. 1 is the plan of steel pipe arch bridge 1, and AB line is that the calculating of steel pipe arch bridge is across footpath.In the embodiment of the present invention, the theoretical altitude coordinates value of AB line is Z0=146171mm.
In the embodiment of the present invention, illustrate with assembled 1st section of arch rib.Fig. 2 is the 1st section of network for location assembled between arch rib and arch springing.The embodiment of the present invention utilizes the method for locating between coordinate method of comparison determination steel pipe arch bridge arch rib mainly to comprise the following steps:
S1, in the assembled network for location of theory (CAD figure), find two control points on arch rib upper and lower string pipe lateral edges line, and measure theory coordinate value.
In the embodiment of the present invention, as shown in Figure 2, in figure, EF line is the end face of the 1st section of arch rib upper flanges 2, and it is for controlling datum with EF end that arch rib installs location.EF line being offset downward 600mm is E'F' line, E'F' line and the theoretical control line installed when normal control wire 3(design) meet at C point, C point is the first Survey control point, can be considered any of winding up on pipe lateral edges line, measures the theoretical coordinate value (X of C point
c, Z
c).
In like manner, find the second Survey control point D on lower chord tube, and measure the theoretical coordinate value (X of this second Survey control point D
d, Z
