Description

Technical Field

[0001] The invention relates to the technical field of tied arch hoisting, and in particular to a tied arch hoisting detection device. Background Art

[0002] The tied arch, also known as the simply supported beam-arch combination system, has been widely developed in my country, especially in Jiangsu and Zhejiang. Arch bridges are mostly built in mountainous areas with good foundations. It is more troublesome to deal with the foundation of arch bridges in plain areas. According to survey data, almost all arch bridges built in plain areas have similar problems as abutment displacement, arch crown drop, and arch rib cracking. The tied arch bridge applies prestress in the tie beam to offset the thrust of the arch rib, so that the piers (platforms) do not need to bear the thrust. The piers (platforms) can be built like continuous beams, solving the problems of arch bridges in plain areas. In addition to being more beautiful than ordinary beam bridges, the tied arch also has a great advantage in cost. The construction height of the tied arch main beam can be about 1 / 50 of the span. On the premise of meeting the navigation requirements, the bridge deck elevation can be minimized, the approach bridge length can be shortened, and the project cost can be saved. Among the bridges that have been built, the construction height of the tied arch with a main span of 50m is only 80cm, which can reduce the construction height by about 1.8m compared with the simply supported beam and by about 1.0m compared with the continuous beam. Its economic advantage is self-evident. According to the width of the bridge deck, the arch rib can be arranged in one piece, two pieces, three pieces or even four pieces. The construction can be divided into two methods: arch first and then beam, and beam first and then arch.
