The operation platform 500 is divided into a plurality of functional platforms and is installed on the tops of the near-shore side support 200 and the far-shore side support 300 in a layered manner. According to the function of the functional platform in different procedures of building the beam section, the functional platform is arranged at different positions on the far pier side bracket, provides different corresponding channels 510 and is correspondingly fixed with the bearing beam 400.

The application provides a method for installing 100 beam segments of cable-stayed bridge auxiliary pier, according to the stress characteristics of 100 beam segments of auxiliary pier, near bank side and far bank side of auxiliary pier 100 are provided with near bank side bracket 200 and far bank side bracket 300 with different structures, and near bank side bracket 200 and far bank side bracket 300 are respectively provided with bearing beam 400 and distribution beam 440, and a beam segment building platform is formed on auxiliary pier 100. And, form a great operation sub-platform in the process of the building of the side support of the far bank, can overcome the hindrance of the said auxiliary pier, and on the premise of not destroying the structure of auxiliary pier, make the beam section that the floating crane or cable-stayed bridge crane transported reach the operation sub-platform of the side of far bank on the auxiliary pier easily, and offer the foundation for the building of the subsequent beam section, the said beam section is put and easy to operate in place on the auxiliary pier, the construction difficulty of the cable-stayed bridge can be reduced, and the construction time is shortened too.

Although a few exemplary embodiments of the present application have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these exemplary embodiments without departing from the principles and spirit of the application, the scope of which is defined in the claims and their equivalents.
