Highway bridges and viaducts often use bridge piers as supports. Therefore, the construction of bridge piers is one of the key factors in road and bridge engineering projects. In the current construction of large cantilever cap beams of bridge piers, in addition to the application of cap beam supports, it is often necessary to apply and install some hoop structures to assist in the implementation of manual operations.

[0028] The sliding hoop structure of this embodiment is specifically used in conjunction with the cantilever cap beam support 3. The sliding hoop structure is connected and fixed to the cantilever cap beam support 3 through a connecting mechanism. In the overall lifting process of the cantilever cap beam support 3, when the cantilever cap beam support 3 performs the lifting operation, the sliding hoop structure is also lifted into place, which simplifies the installation steps and process of the hoop structure of the bridge pier 4, reduces the time for personnel to work at high altitude, improves efficiency, and is conducive to improving the construction safety of the hoop structure. It has wide applicability and can be widely used in various cantilever cap beam support 3 overall lifting construction processes.

[0029] As a further explanation of the present invention, the hoop body includes a fixed hoop ring 5 and a movable hoop ring 6; the fixed hoop ring 5 includes a first fixed hoop ring body and a second fixed hoop ring body, the first fixed hoop ring body and the second fixed hoop ring body are fixedly connected to each other to form a hoop ring with a fixed spacing; the movable hoop ring 6 includes a first movable hoop ring body and a second movable hoop ring body, the first movable hoop ring body and the second movable hoop ring body are movably installed on the fixed hoop ring 5 to form a hoop ring with an adjustable spacing. For details, see 1 and Attachment Figure 2 As shown, the fixed hoop ring 5 includes a plurality of guide rails 7 arranged radially, and the first movable hoop ring body and the second movable hoop ring body are movably arranged through the guide rails 7, thereby realizing adjustment of the distance between the first movable hoop ring body and the second movable hoop ring body.

[0030] As a feasible embodiment, the guide wheel 1 is telescopically arranged on the hoop body, including a guide wheel body and a telescopic rod 8, and the guide wheel body is radially telescopically arranged on the fixed hoop ring 5 through the telescopic rod 8. As shown in the drawings, a telescopic drive device is fixedly arranged on the fixed hoop ring 5, which is used to drive the guide wheel body to extend forward through the telescopic rod 8 to press against the outer wall of the target bridge pier 4, thereby playing a guiding role of the guide wheel body during the hoop structure lifting process and preventing the hoop structure from scratching the cement outer wall of the target bridge pier 4. Based on the structural design of this embodiment, preferably, a plurality of avoidance holes 9 for avoiding the telescopic movement of the guide wheel body are provided on the first movable hoop ring body and the second movable hoop ring body. The avoidance holes 9 are arranged corresponding to the guide wheel 1.
