Embodiment 1

[0043] like Figure 1 ~ Figure 3 As shown, the present embodiment provides a floating tugboat 9 for installing steel girders, the floating tugboat 9 can carry the steel girders used for erecting bridges in water, and the steel girders assembled from the assembled platform of the assembled position, Accurate delivery to the target position, thereby avoiding the construction of structure foundations and false frames in the water, and ensuring that the construction interference during the water construction period is small.

[0044]Specifically, the floating tugboat 9 mainly includes a barge group and a guide mechanism, wherein the barge group is used to carry steel beams for erecting bridges, and the barge group drives the steel beams to move from the assembled position to the target position on the water by moving, and is a steel girder. The beams provide support for water movement; the guide mechanisms are respectively connected to the front and rear ends of the barge group, a...

Embodiment 2

[0053] On the basis of Example 1, this Example 2 proposes a bridge erection system. The implementation of this system has the advantages of small construction interference during the time period of water construction closure, parallel construction, small reinforcement of steel beams, and no need for guide beams. Compared with the existing frame method, there is no need to set frame in the bridge hole, less interference to shipping during the construction period, saving construction costs; compared with the dragging method, there is no need to set guide beams and connecting rods , The amount of steel beam reinforcement is small, saving installation costs.

[0054] The system includes an assembly platform, a slide rail mechanism, a pushing mechanism and a floating tugboat 9 as in Embodiment 1. Among them, the assembly platform is set at the assembling position of the steel beam, and is used to assemble the steel beam section by section; the slide rail mechanism is set on the car...

Embodiment 3

[0061] On the basis of Embodiment 1 and Embodiment 2, Embodiment 3 proposes a bridge erection method, thereby forming an efficient construction process of segment-by-section assembly and dragging. The implementation of this method can avoid the construction of structure foundations and false frames in the water, and has the advantages of small construction interference during the time period of water construction closure, parallel construction, small reinforcement of steel beams, and no need for guide beams. Compared with some scaffolding methods, there is no need to set scaffolding in the bridge hole, the construction period has less interference with shipping, and construction costs are saved; compared with the dragging method, there is no need to set guide beams and connecting rods, and the reinforcement of steel beams is small. Save installation costs.

[0062] The method includes the following steps:

[0063] S1. Respectively preset target positions of steel girder secti...

Abstract

The invention relates to the technical field of water bridge erection equipment, in particular to a floating tugboat for installing steel beams and a bridge erection system and method. The barge group of the floating tugboat drives the steel beam to move on the water by moving, and provides the support buoyancy for the steel beam to move on the water; the guiding mechanism is used to limit and guide the moving direction of the barge group in the water; the bridge erection system and method utilize The assembly platform assembles the steel beams in sections, and each section of the steel beam is pushed to the floating tugboat by the jacking mechanism and the sliding rail mechanism, and the floating tugboat is used to drive the section of the steel beam to the target position on the water, thereby forming a sectioned assembly. The efficient construction process of section-by-section hauling can not only reduce the amount of construction work in the water, but also ensure that the construction interference during the sea closure period of the water construction is small, and has the advantages of parallel construction, small reinforcement of steel beams, and no need for guide beam weight. .

Description

technical field [0001] The invention relates to the technical field of water bridge erection equipment, in particular to a floating tugboat for installing steel girders and a bridge erection system and method. Background technique [0002] Usually bridge erection is mainly carried out in the following ways: (1) use prefabricated beams such as box girders / T beams, and complete erection by lifting and transporting equipment; (2) use T beams to complete erection by hoisting; (3) use mobile molds The frame is erected by direct pouring. [0003] According to the stress state of the main load-bearing structure of the bridge during the construction stage, the bridge erection methods can be classified into three categories: support construction, cantilever construction and overall erection. Among them, the support construction includes frame method, arch method, mobile support method and so on. [0004] Among them, the frame method means that the concrete bridge can be cast-in-sit...
