[0002] Cable-stayed bridges are a common type of bridge. When building and installing cable-stayed bridges, the tower beam and the bridge deck main beam are usually built first, and cable ducts are set on the tower beam and the bridge deck main beam respectively, and then the two ends of the cable are fixed in the cable duct. Among them, the installation accuracy of the cable duct is the key link.

[0003] In order to ensure that the axis of the cable-stayed duct is consistent with the design axis when installing the cable-stayed duct, when adjusting the cable-stayed duct, the cable-stayed duct is usually initially fixed, and then a positioning prism or other positioning marking components are set inside the cable-stayed duct, and then the position is determined by a total station to accurately adjust the cable-stayed duct.

[0004] For the marking parts of the cable-stayed cable conduit, some prior art, such as the cable-stayed bridge cable conduit center positioning device disclosed in Application No. 202321152183.x, uses an adjustment component to adjust the center of the positioning plate and the center of the conduit by telescoping the adjusting screw. When the adjustment is made in this way, the adjusting screw serves as both a contact fixing part of the positioning plate in the conduit and a position adjustment part, so that when a single adjusting screw is adjusted, the contact positions of the other three adjusting screws that abut against the inner wall of the conduit move together and limit the telescoping of the current adjusting screw, which requires repeated adjustment and is difficult to adjust.
