An arch bridge rigid tie rod joining method without temporary stay cables
The invention discloses an arch bridge rigid tie rod joining method without temporary stay cables. The method comprises a longitudinal displacement coarse tuning step and a longitudinal displacement fine tuning step in sequence through a sliding support. The sliding support comprises a lower support plate fixedly arranged on a pad stone, and a support main body arranged on the lower support plate. The support main body slides on the lower support plate to drive a steel truss arch to move so as to realize sequential joining of a main arch and rigid tie rods. According to the method, the temporary stay cables used in a conventional joining method are avoided; the sliding support and adjustable limitation pad blocks are arranged, jacks are used to push the sliding support, and the limitation pad blocks are used to control the sliding distance of the sliding support and carry out temporary locking, so that the purpose of rigid tie rod unstressed joining is realized; and the method is easy and reliable, is easy to control, is high in operability, saves construction procedure and construction period, improves production efficiency, is obvious in economic advantages, and has very good application prospects.
