Abstract

The invention discloses a measurement and control method for bridge construction. The measurement and control method comprises the measurement on the following parameters: plane control and measurement, elevation control and measurement, perpendicularity control and measurement, beam part construction measurement, template offset correction control, high pier sedimentation and beam body creep monitoring. By using the measurement and control method disclosed by the invention, all corresponding control measures and methods are proposed by analyzing all factors influencing the construction measurement accuracy, so that the influence of human factors on the construction accuracy is scientifically and effectively reduced, and the setting-out accuracy is effectively guaranteed; and the construction method is simple and reliable and the adaptability is wide.

Description

Technical field [0001] The invention involves a bridge engineering field, which specializes in a measurement control method for bridge construction. Background technique [0002] For large span tall bridge pier bridges, the measurement control of the bridge is crucial. How to ensure that the measurement control meets the construction requirements during the bridge construction process is a general concern. [0003] At present, the factors that affect the accuracy of high -pier construction are divided into natural factors and human factors. Among them, natural factors mainly refer to the temperature load caused by wind load, solar radiation, and heating up;, Then affect the quality of construction.Therefore, it is necessary to reduce the impact of construction accuracy caused by human factors through some measurement methods. This is a technical problem that has always been solved. Invention content [0004] The purpose of the present invention is to overcome the above problem...
