Description

Technical Field

[0001] The present application relates to the technical field of arch bridge construction, and in particular to a high-speed railway tied arch bridge arch rib concrete jacking structure and a construction method. Background Art

[0002] A tied arch bridge is a type of bridge that combines the advantages of both arches and beams. It combines the two basic structural forms of arch and beam to jointly bear the load. A tied arch bridge uses arch ribs and installs hangers on the arch ribs to assist in stabilizing the tied arch bridge. At the same time, concrete is filled in the arch ribs to strengthen the supporting capacity of the arch ribs.

[0003] With regard to the above-mentioned related technologies, the inventors believe that the pouring progress of the arch rib concrete of the traditional tied arch bridge is relatively slow when pumped by a ground pump. The opening of holes in the arch rib to vent air and the synchronization of the concrete pouring progress on both sides need the cooperation of special personnel. The manual knocking to check the quality of the concrete pouring has low verification accuracy. There are often common quality problems such as cavities and looseness in the arch rib concrete, and there may be problems with asynchronous concrete filling, which may lead to unstable arch ribs.
