With the vigorous construction of highways, highways and various special lines for passenger and freight transportation, a plurality of bridges which need to cross deep canyons or large-scale river channels appear in succession, and the construction of the bridges usually needs to be carried out by adopting a bridge turning method. The bridge turning method is a construction method for positioning a bridge structure in place through turning after a bridge structure is manufactured and formed at a non-designed axis position. The turning construction method has the advantages of economy, convenience, reliability, no interference to traffic, uninterrupted navigation, capability of crossing deep ditches and rivers and the like, and more constructions are adopted in recent years.
The current common swivel construction method is a horizontal swivel construction method. In the bridge rotation construction process, an important factor influencing whether the horizontal rotation of the rotation beam is successful is whether the height difference between the bottom of the rotation beam and the boundary pier meets the design requirement. The rotator beam is poured and finished in the frame releasing process, and the beam end can generate certain downwarping due to self weight. In the process of rotating, the beam end may also be lowered due to the influence of the flatness of the flat hinge or the influence of the spherical radian of the spherical hinge. Therefore, if the height difference between the bottom of the swivel beam and the pier top of the boundary pier is small, the installation of the pier top support is not facilitated. If the bottom of the swivel beam is lower than the top of the pier of the junction pier, the swivel beam cannot be accurately positioned.
At present, the height difference between the bottom of a swivel beam and the top of a pier of a junction pier is mainly monitored by a total station and a level gauge. The total station has higher monitoring precision, but the instrument equipment is expensive and has higher cost, and the monitoring precision is influenced by the state of the prism. The precision of the level gauge monitoring is influenced by the placement and observation distance of the leveling rod and the ambient light, and the precision is low. And these two kinds of instruments all need personnel to install supporting observation device near the bottom of the beam, such as prism, sopwith staff, and personnel's installation operation has certain safety risk.
