Description

Technical Field

[0001] The present invention relates to the technical field of cofferdam transportation, and particularly relates to a cofferdam transportation structure and a transportation system. Background Art

[0002] A cofferdam refers to a temporary retaining structure built during the construction of a water conservancy project for the construction of permanent water conservancy facilities. Usually, after the cofferdam is manufactured on land, a cofferdam transportation device is required to transport the cofferdam to the site.

[0003] When a long-span bridge crosses a large river or a large stream, its main pier foundation has a large cross-section, is wading in water and has a large water depth. Usually, a double-wall steel cofferdam is used for support construction. The double-wall steel cofferdam is usually prefabricated and processed in a factory and then transported to the bridge site for hoisting and lowering. In the prior art, the double-wall steel cofferdam is usually divided into multiple small sections and then transported to the bridge site for assembly and lowering. This method has relatively low requirements for the selection of transportation conditions and less transportation costs, but the on-site assembly efficiency is relatively low and the quality of the cofferdam is difficult to control. When choosing integral transportation, the cross-sectional width of the cofferdam is too large and the integral transportation is difficult. Summary of the Invention

The plurality of support parts are spaced apart on the hull deck, and each support part extends transversely along the hull deck to the outside of the hull deck to support the cofferdam to be transported. The cofferdam transportation structure in the present invention is formed by the hull deck and a plurality of support parts.

When the cofferdam transportation structure in the embodiment of the present invention is used to transport the cofferdam, the requirement for the selection of the hull deck is relatively low, which is convenient for transporting the cofferdam with an excessively large cross-sectional width and reduces the overall transportation difficulty.

[0022] As an optional implementation manner, in an embodiment of the invention, refer to Figure 4 As shown in the figure, each support part 2 is provided with a first support member 21, a second support member 22, a cross beam 23, a vertical pressure bar 24 and two diagonal tension bars 25. The first support member 21 and the second support member 22 are spaced apart transversely on the hull deck 1. The cross beam 23 is arranged on the first support member 21 and the second support member 22. The cross beam 23 extends transversely to the outside of the hull deck 1 to support the cofferdam 3 to be transported. The vertical pressure bar 24 is arranged in the middle of the cross beam 23. The two diagonal tension bars 25 are respectively arranged on both sides of the vertical pressure bar 24.
