[0026] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0027] like Figures 1 to 3 As shown, according to an embodiment of the present application, a box girder structure is proposed, including: a tire frame 110; a corrugated tube 120, the corrugated tube 120 is inserted into the tire frame 110 and arranged along the length direction of the box girder structure; an anchor plate 130, the corrugated tube 120 passes through the anchor plate 130; a sheath 140, the sheath 140 is sleeved on the corrugated tube 120, so that the pores of the corrugated tube 120 and the anchor plate 130 are concentric.

[0028] The box girder structure provided in the embodiment of the present application includes a tire frame 110, a corrugated pipe 120, an anchor plate 130 and a sheath 140. Based on this, during the construction process, the corrugated pipe 120 can be first passed through the tire frame 110 and the anchor plate 130, and then the sheath 140 is used to position the corrugated pipe 120 so that the pores of the corrugated pipe 120 and the anchor plate 130 are concentric, and then concrete pouring, hole cleaning, tensioning and grouting operations are performed. Through the setting of the sheath 140, It can avoid the end of the corrugated pipe 120 from being offset, reduce the probability of concrete leakage, ensure the compactness of concrete, and reduce the probability of anchor tails, ensuring that the anchor can be inserted into the slot of the anchor pad 130, preventing concrete from entering the anchor pad 130, accurately positioning the anchor during prestressing, improving the concrete density of the densified area behind the anchor pad 130, and reducing the difficulty of manual hole cleaning before tensioning. Compared with traditional processes, it makes tensioning and grouting operations more efficient, ensuring the quality of the box girder structure.

[0029] It is understandable that after the construction of the box girder structure is completed, the sheath 140 mounted on the corrugated pipe 120 can be removed, so that the sheath 140 can be recycled, which can make the construction of the box girder structure convenient and quick, save operation time, improve work efficiency, and save materials for the corrugated pipe 120.

[0030] It is understandable that during the construction of the box girder structure, before pouring the concrete, check whether the sheath 140 is damaged. If damaged, replace it in time; check whether the sheath 140 matches the aperture size of the bellows 120 and the anchor plate 130; the sheath 140 should be screwed into the root of the anchor plate 130 to give full play to the sealing effect. When removing the sheath, control the concrete strength to prevent premature removal and avoid concrete outflow.

[0031] like Figures 1 to 3As shown, in a feasible implementation manner, the box beam structure further comprises: a concrete layer, wherein the concrete layer covers the tire frame 110, the corrugated pipe 120, and the anchor plate 130. Such an arrangement can ensure the strength of the box beam structure.

[0032] like Figures 1 to 3 As shown, in a feasible implementation, the sheath 140 includes: a connecting portion 131, which is sleeved on the corrugated tube 120; and a positioning portion 132, which is connected to the connecting portion 131. Such a configuration facilitates installation, positioning and removal of the sheath 140.

[0033] In a feasible implementation, the positioning portion 132 and the connecting portion 131 are an integrated structure, and the sheath 140 is made of a silicone material. This arrangement ensures the mechanical strength of the sheath 140 and enables the sheath 140 to have a certain deformation ability, which facilitates the installation, positioning and removal of the sheath 140.

[0034] like Figures 1 to 3 As shown, in a feasible embodiment, there are multiple sheaths 140, and the sizes of the multiple sheaths are different. Such an arrangement enables the corrugated tube 120 to be assembled into anchor pads 130 of different sizes and specifications, thereby improving assembly efficiency.

[0035] like Figures 1 to 3 As shown, in a feasible implementation, there are multiple bellows 120, and each bellows 120 is covered with a sheath 140. Such an arrangement can improve the mechanical strength of the box beam structure.

[0036] It can be understood that, through the arrangement of multiple bellows 120, firstly, in the construction of the box girder structure, the bellows 120 can protect the prestressed steel strand (or prestressed tendons) from being contaminated during the pouring of concrete, thereby ensuring the quality and effect of tensioning; secondly, the bellows 120 can be used as a channel for the prestressed tendons in the box girder structure. After tensioning, the prestressed steel strand is consolidated with the box girder structure by injecting high-strength concrete (slurry) into the bellows 120 to form an integral force system, thereby achieving the tensioning effect and enhancing the bearing capacity and stability of the box girder; thirdly, due to changes in ambient temperature, changes in medium temperature, and irregular installation of pipelines, the length of the pipeline may change. The bellows 120, with its flexible structure, can effectively compensate for this length change and ensure the normal operation of the pipeline (or prestressed tendons); fourthly, during the construction of the box girder structure, it will be affected by various forces (such as internal pressure, external gravity, etc.), resulting in displacement of the connection. The bellows 120 can compensate for this displacement through its flexibility to ensure the normal operation of the connection. Fifthly, the bellows 120 also has the function of absorbing vibration and reducing noise. When the box girder structure is subjected to external excitation (such as vehicle passing, wind load, etc.), the bellows 120 can absorb part of the vibration energy, reduce the noise level, and improve the comfort and service life of the bridge.
