Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and more specifically to a box girder maintenance device for high-speed railway construction. Background Art

[0002] A box girder is a type of beam in bridge engineering. According to the preparation method and location, box girders are mainly divided into precast box girders and cast-in-situ box girders. To accelerate the construction progress and save the construction period, precast box girders are mainly used now. During road construction, a suitable location near the construction site is selected for the precast work of box girders. The precast site of box girders requires a large area, so the precast sites are mostly open field sites.

[0003] For the precast of box girders, first, the internal reinforcement of the box girder is tied with steel bars on the bottom formwork, then the internal formwork and end formwork are installed, and concrete is poured. After the precast box girder solidifies and hardens, form removal and maintenance are carried out. The existing maintenance methods mainly use plastic film to cover and wrap the precast box girder, and a steam generator is used to generate steam, which is transported through pipes to the inside of the plastic film to provide a suitable maintenance environment for the precast box girder, or a method combining gantry and canvas is adopted. For example, in Chinese Patent CN20221111890, a disclosed precast box girder maintenance device includes a pedestal, a slide rail, a pulley, a gantry and a canvas. After the poured precast box girder is moved to the top surface of the pedestal, multiple slide rails are fixed on both sides of the pedestal with bolts, the pulley is slidably installed inside the chute of the slide rail, the pulley is pushed to slide along the slide rail, so that multiple gantries slide and unfold, driving the canvas to unfold, covering and wrapping the precast box girder, and a steam generator is used to generate steam, which is introduced to the outside of the precast box girder through pipes. Although this device can realize the maintenance of box girders, it has many components, is difficult to disassemble and assemble, has a high cost, and is not easy to install and replace.
