[0071] The usage is:

[0072] During use, according to construction needs, the storage device for bellows and liners can be used as a hanger for temporary lifting of bellows and liners, or can be placed on the bridge deck to store liners. Before pouring concrete for a large-span prestressed continuous bridge or a continuous rigid frame bridge, a liner needs to be inserted into the bellows to prevent the impact of concrete from causing the bellows to deform or shift, affecting the prestressed arrangement of the entire bridge. After the concrete is poured and the strength reaches a certain level, the liner can be taken out and liners of different types can be placed in the device for next use; at the same time, the lifting lug 1 can be used in conjunction with the lifting equipment to transport the bellows and liners vertically and lift them horizontally. When there is no lifting equipment or the lifting equipment cannot reach it, when it is necessary to move it at the bottom of the pier and the bridge deck, the walking wheel 6 can be used to move it to the designated position. When there are too many bellows and liners, they can be temporarily stored in the device. By turning the handle 95 to release the rainproof and flame-retardant tarpaulin 94, rainwater can be prevented from eroding the materials. The tarpaulin is made of flame-retardant material, which can prevent fire to a certain extent. When the material is needed, the handle 95 needs to be turned to store the tarpaulin, which is convenient and can reduce resource waste. When the length of the material exceeds the device, the side tarpaulin supporting telescopic rod 8 can be pulled out and then covered with the tarpaulin to achieve the purpose of rain protection.

[0073] The quality requirements during use are:

[0074] During the welding process, ensure that all rods are horizontal and vertical, and that the welding parts are fully welded. After welding, knock off the welding slag and conduct weld quality inspection to ensure that the weld quality meets the requirements and avoid welding during the lifting process. After the above steps are completed, spray the device with anti-rust material to improve its durability.

[0075] In summary, the utility model has a simple structure and strong practicality. The device can be used to hoist and move the corrugated pipe and the liner, effectively preventing the corrugated pipe from being damaged or irreversibly deformed during the hoisting process, thereby improving the safety and stability of the hoisting process. At the same time, the setting of the rainproof equipment can prevent the material from being eroded by rainwater. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
