In some embodiments of the present application, the auxiliary supporting mechanism 20 is a telescopic structure, and the auxiliary supporting mechanism 20 can stretch out and draw back along the X direction, so that the auxiliary supporting mechanism 20 can perform height adjustment according to the distance from the second positioning portion 142 to the supported box girder, and the supporting requirements can be met at different setting positions, so that the application is wide, and the processing and production of the auxiliary supporting mechanism 20 are facilitated.

Further, an end of the auxiliary supporting mechanism 20 away from the second positioning portion 142 is higher than the first positioning portion 141, so as to ensure that the first positioning portion 141 does not contact with the box girder when the auxiliary supporting mechanism 20 supports the box girder.

The fact that the end of the auxiliary supporting mechanism 20 away from the second positioning portion 142 is higher than the first positioning portion 141 means that the end of the auxiliary supporting mechanism 20 away from the second positioning portion 142 is higher than the end of the first positioning portion 141 away from the end plate 12. In some embodiments of the present application, the end of the first positioning portion 141 facing away from the end plate 12 is spaced from the box girder by 10-50mm to avoid interference with the first positioning portion 141 due to vibration of the box girder.

Further, the one-column pier nondestructive reinforcing support device 1 may be provided with a cover plate as the outer peripheral surface of the support structure 10. For example, in some embodiments of the present application, as shown in fig. 1, 3 and 4, the unimpaired stud reinforcing and supporting device 1 is provided with a first cover plate 161 and a second cover plate 162, the first cover plate 161 is connected to the side of the second portion 1312 facing away from the end plate 12, and the second cover plate 162 is connected to the side of the first portion 1311 facing away from the anchor ear 11. The provision of the first cover plate 161 and the second cover plate 162 enables the plurality of supporting members 131 to be connected as a single body, enhancing the strength of the supporting member 13.

It should be noted that, unless otherwise specified, all the components having a connection relationship in the present application may be connected by welding.

It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
