Description
TECHNICAL FIELD
[0001] The utility model relates to a cable guide pipe orifice measurement positioning support and belongs to the technical field of bridge construction. BACKGROUND
[0002] The cable-stayed bridge is a high-order statically indeterminate structure with complex stress, great mutual influence between components, and controllable internal force and linearity. The cable guide pipe is one of important components in the cable anchoring area, and accurate positioning and installation can effectively prevent the cable-stayed cable from being damaged due to friction with the cable guide pipe wall and affect the quality of the cable-stayed bridge. The welding process of the cable guide pipe and the subsequent bridge body concrete pouring process are prone to cause the cable guide pipe that has completed positioning to deviate from the position. Once the cable guide pipe deviates from the position, the cable-stayed cable is prone to rub against the cable guide pipe during subsequent cable-stayed cable tensioning, which affects the overall stress of the cable-stayed cable. Since the cable-stayed cable and the bridge tower form a spatial angle, and the positions of the cable-stayed cables at each layer are different, the angle of the cable-stayed cable will also change, and at the same time, the spatial positions of the cross-anchored cable-stayed cables are more complex, which puts higher requirements on part blanking, processing, and cable guide pipe positioning.
[0003] At present, the cable guide pipe orifice coordinate measurement and positioning in the field of cable-stayed bridge construction usually adopts the method of measuring the center coordinates of the orifice positioning disc by using a total station. During measurement, the measurement personnel need to place the measurement prism on the reserved prism point of the orifice positioning disc, which is time-consuming and laborious. The measurement accuracy is easily affected by the environment, and there are safety hazards. Especially when the prism and the total station are not accurately connected and the ground environment is not suitable for the movement of the total station to connect with the prism, the construction personnel need to work high above the ground to adjust the angle of the prism.
