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 hanging basket method cantilever casting corrugated steel web skew box girder bridge construction method. The comprises the following steps: (1) assembling triangular hanging baskets, pre-pressing the triangular hanging baskets, and anchoring the triangular hanging baskets at the tops of piers; (2) binding bottom plate reinforcing steel bars, and arranging a bottom formwork and side formworks, hoisting the corrugated steel webs and connecting the corrugated steel webs, binding top plate reinforcing steel bars, and arranging a top template; (3) pouring a bottom plate,then pouring the top plate, and symmetrically and continuously pouring relative to the pier top during pouring; (4) dismounting a template support and a pull rod, jacking up the triangular hanging baskets through a supporting jack, placing pulley structures at all steel supporting positions of the triangular hanging baskets, then anchoring the pulley structures to the pier top through limiting anchor rods, and installing a traction device and a walking pressing wheel; and (5) after the triangular hanging baskets move in place, anchoring the triangular hanging baskets, and carrying out cyclicconstruction according to the sequence. Therefore, the triangular hanging baskets are simpler in structure, the time for laying the rail 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...
