Background
With the rapid development of national economy, bridge engineering construction technology is also rapidly advancing, and large-span concrete-filled steel tube arch bridges are more and more appeared in our lives. The steel pipe concrete arch bridge is generally constructed without a support, namely, before concrete is poured, steel pipe arch ribs are processed and manufactured in a processing plant, the line shape of the steel pipe concrete arch bridge is formed after the procedures of blanking → cutting → short pipe → long pipe → pre-assembling → hoisting, and then the steel pipe which is already installed is used as a template to pour the concrete in the pipe. Therefore, linear control of the hoist is very important. The traditional linear control method is generally to weld a scale marked on the side surface of the arch rib for observing the transverse deviation of the arch rib, and weld a prism head on the arch rib for measuring the elevation of the arch rib. The former method for installing the prism is simple and rough, but cannot ensure the verticality of the prism rod; the latter method for mounting the prism lens can ensure the verticality of the prism rod, but different set squares need to be manufactured according to different radians of arch ribs at different positions to ensure the verticality of the prism. Both of these methods are either not accurate enough or are cumbersome to manufacture. Therefore, the linear measuring device for the steel tube arch ribs is provided, and a prism lens of a total station is convenient to mount.
