Embodiment Construction

[0036] The construction method of the cantilevered corrugated steel web oblique box girder bridge of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0037] For ease of description, the bridge extension direction is set as the longitudinal direction extending along the front-rear direction, and the bridge width direction is set as the transverse direction extending along the left-right direction. The triangular hanging basket includes the main truss system, anchor system, bottom basket system, suspension system, and walking system.

[0038] Such as figure 1 As shown, the main truss system includes three sets of main trusses and transverse connecting beams fixedly connected between adjacent main trusses. The main truss includes a main longitudinal beam 1 extending along the extension direction of the bridge, a vertical rod 2 arranged longitudinally in the middle of the main longitudinal be...

Abstract

The invention relates to a construction method for cantilevered corrugated steel web oblique box girder bridges with hanging basket method, which includes (1) assembling triangular hanging baskets, preloading the triangular hanging baskets, and anchoring the triangular hanging baskets on the pier top; (2) Bind the bottom slab reinforcement, arrange the bottom formwork and side formwork; then hoist the corrugated steel web and connect the corrugated steel web; bind the top slab reinforcement and arrange the top formwork; (3) pour the bottom slab, then pour the top slab, and pour it relative to the top of the pier Symmetrical continuous pouring; (4) Remove formwork supports and tie rods, use support jacks to jack up the triangular hanging basket, place pulley structures at each steel support position of the triangular hanging basket, and then use limit anchors to anchor the pulley structure on the top of the pier, Then install the traction device and the walking pressure roller; (5) After the triangular hanging basket is moved in place, anchor the triangular hanging basket, and carry out cyclic construction according to the above sequence. The structure of the triangular hanging basket is simpler, the time for laying the track is saved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a cantilever construction method with corrugated steel webs, in particular to a construction method for cantilever pouring corrugated steel webs oblique box girder bridges by hanging basket method. Background technique [0002] Prestressed concrete bridges with corrugated steel webs have a series of advantages such as good seismic performance, high structural strength, and good economy. With the continuous development of theory and practical applications, corrugated steel webs are more and more popular in bridge construction. of favor. Unlike traditional construction methods, corrugated steel webs are usually constructed using the cantilever construction method. [0003] Cantilever pouring of corrugated steel web box girder bridges is usually constructed using the hanging basket method, and generally diamond-shaped hanging baskets or triangular hanging baskets are used. During the construction process of traditional hanging ba...
