Embodiment 1

[0035] refer to Figure 1 to Figure 7 as shown, figure 1The number 1 is the bridge pier, and the number 2 is the cover beam. The construction of the bridge pier is a necessary construction content in the early stage. The track beam bridge pier is generally a reinforced concrete structure. No. 3 is the track beam. The track beam has been assembled in the special beam assembly tool before erection, and the post-cast concrete at the mid-span and beam end has reached the required strength of the hanging beam. The prestressed steel beam of the track beam has been prestressed. pull construction. No. 4 is the No. 1 beam transport vehicle, and No. 5 is the No. 2 beam transport vehicle. Each beam transport vehicle can be independently controlled to start and stop. At the same time, two beam transport vehicles can also be grouped to start and stop synchronously. For beam transport vehicle load, each beam transport vehicle is designed with 8 sets of traveling wheel sets and 4 sets of l...

Abstract

The invention discloses an embedded maglev elevated line bridge erecting machine girder erection construction method. The method comprises the following steps that bridge erecting is conducted on a bridge erecting machine; the track beams go on the bridge; transporting the beams; erecting a beam; crossing the bridge girder erection machine; and circularly constructing. The track beam has the advantages that the track beam body is high in geometric accuracy, light in dead weight and limited in bearing capacity, beam transporting loads are effectively dispersed through double-vehicle beam lifting of the beam transporting vehicle, curve beam erecting is achieved through transverse displacement of the machine arm on the stand column cross beam, double-line beam erecting of the single-line walking bridge girder erection machine is achieved through the beam moving sliding rail and the sliding shoe at the top of the bent cap, and the construction efficiency is improved. Self-walking transition of the bridge girder erection machine on an erected line is achieved through a girder transporting vehicle carrying machine arm.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a construction method for a built-in maglev elevated line bridging frame girder. Background technique [0002] At present, in the conventional simply supported bridge erection frame girder construction technology, most of the erected girders are box-shaped and T-shaped sections, and a few are U-shaped sections. The construction object of the bridge frame girder is the embedded magnetic levitation track girder. At present, the construction method of the bridge frame girder for the U-shaped cross-section frame type magnetic levitation track beam is still blank in the bridge erection machine transport girder industry. [0003] The embedded magnetic levitation track beam has the characteristics of small cross-section and light structure. The weight of a simply supported track beam with a span of 24 meters does not exceed 100t. Combined with the bearing capacity of t...
