[0002] At present, the hanging basket construction is mainly used in the cantilever pouring construction of large-span prestressed concrete. The hanging basket construction refers to the use of the hanging basket method to cast the cantilever bridge with a larger span in situ. It does not require the erection of brackets and does not use large cranes. The hanging basket is often used in the construction of large-span and ultra-wide bridges. Compared with other methods, it has the advantages of light structure, simple and convenient assembly, and no pressure. The design principles of the hanging basket: light weight, simple structure, strong and stable, easy to move forward and assemble and disassemble, strong reusability, small deformation after being stressed, etc., and there is sufficient space under the hanging basket, which can provide a larger construction working surface, which is conducive to the construction operation of the steel formwork.

[0003] The traditional hanging basket is easy to overturn, has high labor intensity, and is difficult to move the hanging basket and formwork. In the cantilevered concrete casting of the hanging basket, the main method is to cover the top surface of the segment concrete with water storage materials for artificial watering and curing, the inner cavity of the box beam is artificially watered, and the outer surface of the web is sprinkled or sprayed with curing liquid. However, the flange plate and the bottom surface of the bottom plate of the box beam are basically impossible to be maintained, and the parts that are manually maintained also have the disadvantages of large randomness and poor sustainability, which leads to inadequate curing of the cantilevered box beam segment concrete.
