Description

Technical Field

[0001] The utility model relates to the technical field of bridges, in particular to an auxiliary positioning and installation device for bridges. Background Art

[0002] As the most important foundation type in bridge engineering, bridge pile foundations have developed rapidly and are widely used. During the construction of bridge pile foundations, prefabricated piles need to be driven into the pile holes. If they become skewed during this process, the construction quality will be seriously affected. Patent Publication No. CN215925970U, entitled "A Bridge Pile Foundation Construction Auxiliary Positioning Device," discloses a technical solution using two positioning plates for positioning. The positioning plates are cylindrical, which can easily guide the pile foundation and ensure its stable installation position. A trumpet-shaped guide plate is also provided on the upper part of the positioning plates, which helps the pile foundation slide naturally between the two positioning plates during lifting. The assembly structure of the two positioning plates facilitates removal. However, during installation, a certain gap is required between the pile foundation and the positioning plates to facilitate the pile foundation to enter the cylindrical structure formed by the two positioning plates. If the gap is too small, the pile foundation installation is not convenient. If the gap is too large, the pile foundation positioning is easily affected. Therefore, it is necessary to design an auxiliary positioning and installation device for bridges to facilitate the installation of pile foundations and their positioning and support.
