Method for synchronous construction of variable-spacing double-width bridge by adopting segment assembling bridge erecting machine

Abstract

The invention discloses a method for synchronous construction of a variable-spacing double-width bridge by adopting a segment assembling bridge erecting machine. Synchronous erecting of the variable-spacing double-width bridge is achieved through one bridge erecting machine, and the bridge erecting machine comprises a pair of transverse beams, a pair of main beams, and a pair of hoisting overheadcranes; the length direction of the pair of transverse beams is arranged in the transverse bridge direction, and the pair of transverse beams is fixed to a first bridge pier and a second bridge pier adjacent to the front end of the first bridge pier through vertical columns correspondingly; the length direction of the pair of main beams is arranged in a spaced mode in the longitudinal bridge direction, and the pair of main beams can be slidably erected on the upper portions of the first bridge pier and the second bridge pier in the longitudinal bridge direction; the main beams can be slidablyarranged on the pair of transverse beams in the transverse bridge direction; the pair of hoisting overhead cranes and the main beams are arranged in a one-to-one correspondence mode; and the hoistingoverhead cranes can be slidably arranged on the corresponding main beams in the longitudinal bridge direction. The method has the advantages that the construction period can be greatly shortened, andconstruction is convenient, and can be widely applied to the technical field of construction methods of double-width bridges.

Description

technical field [0001] The invention relates to the technical field of double-width bridge construction methods. More specifically, the present invention relates to a method for synchronous construction of a variable-spacing double-width bridge using segmental assembly bridge erecting machines. Background technique [0002] For the segmental prefabricated bridges of double-lane highways, the current domestic segmental erecting machines are generally used for traditional single-width bridge construction, that is, after the construction of one bridge, the whole machine is moved laterally to the other bridge through the traverse luffing mechanism. construction. This construction method needs to move the bridge erecting machine back and forth laterally twice, that is, after the mobile bridge erecting machine completes the construction of a pair of bridges, it will move the whole machine to another bridge again through the transverse movement luffing mechanism. The number of br...

Problems solved by technology

This construction method needs to move the bridge erecting machine back and forth laterally twice, that is, after the mobile bridge erecting machine has constructed a pair of bridges, it will move the whole machine laterally to another bridge for construction through the traverse luffing mechanism again, and the erection of the single construction The number of bridge crane passes doubles, which greatly increases the operational risk of the equipment and prolongs the construction period

And in the patent that the application number is CN201710910609.6, and the application name is the method for synchronous construction of equidistant double-width bridges using segmental assembly bridge erecting machines, the simultaneous construction method of equidistant double-width bridges is disclosed. For double-width bridges with variable spacing, or Unable to achieve simultaneous construction
