Abstract

The invention discloses an ultra-wide bridge hanging basket structure and an implementation method. The hanging basket structure is realized by adopting a plurality of groups of main bearing beams and stand columns, so that the bearing requirement of an ultra-wide beam is ensured; The hanging basket structure is further provided with a hanging basket bottom platform. The main bearing beams and the stand columns are connected through the inclined pull belts, the bearing lower sliding rails are designed below the bottom platform of the hanging basket, the transverse span of the bottom fence is reduced, and the gravity of an overweight structure during walking is shared. According to the ultra-wide bridge hanging basket structure, the construction problem of any ultra-wide suspended pouring segmental beam is solved; The method has the advantages that (1) the development of the ultra-wide section suspended pouring bridge is promoted; (2) graded construction at the current stage is changed into one-time segmental pouring, so that the construction quality, progress and cost are guaranteed; and (3) the safety degree of hanging basket construction is further improved through the structural design and invention of the hanging basket.

Description

technical field [0001] The invention relates to the field of civil engineering bridge construction, in particular to a design and implementation method of a hanging basket structure suitable for the construction of bridge cantilever ultra-wide sections. Background technique [0002] Hanging basket is the beginning of long-span bridge construction, but with the vigorous development of traffic today, the traffic volume is increasing day by day, and the design of ultra-wide bridges is also increasing. It is difficult to exceed the width of steel structure bridges. At present, the main super-wide hanging basket construction bridges are basically pouring the entire section in stages, that is, the main girder box chamber is poured first, and then the flange is poured. The conventional hanging basket design limits the design of super-wide concrete bridges, and the construction is cumbersome, low in efficiency, and difficult in quality control. Contents of the invention [0003]...
