Description

Technical Field

[0001] The utility model belongs to the technical field of arch bridge construction and provides a heavy-load supporting double hull structure. Background Art

[0002] The bridge type and structural structure of an arch bridge are mainly determined by its construction plan. At present, the construction plans for large-span arch bridges on water include: cable hoisting plan, bracket plan, rotation construction plan, etc. The main problems are as follows: The cable hoisting plan requires the installation of multiple high towers, installation of buckles, back cables and ground anchors, and the use of large-tonnage cable cranes to assemble the arch ribs and bridge decks. The use of cable cranes requires large investment and high cost. The construction process is greatly affected by wind and has high risks. The entire construction process has a great impact on the safety of passing ships. The bracket construction plan requires the installation or pouring of scattered parts on the bracket, which requires a large number of temporary brackets and a long construction period. It is not suitable for bridges with navigation requirements. The rotation construction plan sets up brackets on the river bank or in the water. After the arch ribs are assembled, the arch ribs are rotated and the bridge deck is installed. The rotating disk of the rotation is expensive, the wind is greatly affected during the rotation process, the risk is high, and the construction period is long.

[0003] With the development of economy and society, the construction of long-span steel bridges increases year by year, and more and more of them are used to cross rivers. For example, some inland rivers have wide river surfaces, but there is a lack of large-tonnage transportation and lifting ships in the basin, which limits many processes. In order to expand the construction technology of long-span arch bridges in inland river basins, it is urgent to provide a double-hull structure for the construction of inland river long-span arch bridges to be used in the ship transportation and vertical lifting of the construction structure on board and off the frame.

By adopting the above scheme, this heavy-load supporting double hull structure has the advantages of strong carrying capacity, good stability and solid structure. It is suitable for occasions where heavy-load arch bridges need to be transported, and provides an efficient and safe transportation solution for engineering construction and other fields.

[0024] In this embodiment, the main body of the floating ship 1 is composed of a keel frame 11 and a supporting beam 12.

Figure 4 (c) and installing the support members 9 to be connected to the arch rib support frame 8 with the bottom support removed on the two floating vessels 1, as shown in FIG. Figure 4 (d); Then, the two floating vessels 1 are synchronously drained and floated, so that the support member 9 is fixedly connected with the arch rib support frame 8 of the removed bottom bracket, and then the connection structure between the arch rib support frame 8 and the arch bridge 7 provided on the three-stage pedestal 6 is removed; then, the two floating vessels 1 are continuously synchronously drained and floated, so that the two floating vessels 1 support the arch bridge 7 through the support member 9 and the arch rib support frame 8 connected thereto, and then the arch rib support frame 8 provided on the three-stage pedestal 6 is quickly removed, as shown in FIG. Figure 4 (e); then the two floating boats 1 are synchronously filled with water and sunk, and the lower ends of the two sides of the arch bridge 7 are not in contact with the three-stage pedestal 6; that is, the structural system conversion is simply as follows: the water in the sinking and floating water tank 2 of the floating boat 1 is drained out to make the boat body float on the arch rib support frame 8, the support member 9 of the structure and the bearing beam 3 on the floating boat 1 are connected as a whole, and then the arch or beam is released from the top support connection system of the three-stage pedestal 6, and the water is continued to be drained so that the beam or arch is completely separated from the three-stage pedestal 6 support. The arch rib support frame 8 of the three-stage pedestal 6 is quickly dismantled to complete the structural support force system conversion; finally, the two floating ships 1 are integrally connected by the steel truss 41 of the floating support 4 through the connecting assembly 5 to form an integral support system, and the sinking and floating water tank 2 is installed on the steel truss 41, and then the two floating ships 1 are synchronously dragged out of the three-stage pedestal 6 to complete the double-ship integral floating onboard and off-shore of the arch bridge 7, and used for hoisting and installation in an open river or open sea, such as Figure 4 (f).
