Abstract

The invention relates to a dismantling method of a catenary hinge-rib-free arch bridge. The dismantling method of the catenary hinge-rib-free arch bridge comprises the following steps that (1) erecting a side span support; (2) pre-cutting a beam body; (3) jacking a carrying system in place; (4) cutting a suspender and cutting and dismantling an arch ring; (5) removing a beam body; and (6) crushing and chiseling. According to the dismantling method, the catenary hinge-rib-free arch bridge can be safely, rapidly and conveniently dismantled.

Description

technical field [0001] The invention relates to a bridge dismantling method, in particular to a catenary hingeless rib arch bridge dismantling method. Background technique [0002] With the development of social economy, the service level of some expressways obviously lags behind the current economic development. In order to improve the traffic capacity and better serve the economic development of surrounding areas, it is necessary to renovate and expand this part of the expressway. During the construction process of expressway reconstruction and expansion, it is often encountered that the upper-span flyover is demolished and rebuilt to meet the needs of reconstruction and expansion. [0003] But there is not yet a safe, fast and convenient method for dismantling catenary hingeless rib arch bridges. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a method for dismantling a catenary hingeless rib arch bridge th...
