Light steel structure and heavy steel structure, as a new structural form, have been favored by more and more users with their advantages of light weight, easy installation, safety, environmental protection and strong plasticity. The scope of application is also becoming increasingly wide. With these advantages, with the continuous growth of my country's steel industry and the increasing attention of the country and society to new materials, steel structure has become a new building material that the country vigorously promotes and applies.

[0003] The shield technology based on circular steel structure modules is widely used in underground railway tunnels, cross-river highway tunnels, water conservancy project tunnels, etc. During the production process of circular steel structure modules, large circular steel structure modules will be divided into multiple sub-modules for processing, and the sub-modules will be assembled at the construction site.

[0004] However, during the on-site submodule assembly process, horizontal or vertical misalignment is very likely to occur, and it is difficult to adjust. At present, existing technical devices cannot solve this problem well. Utility Model Content

[0005] The purpose of the utility model is to provide an on-site assembly platform for circular steel structure modules, which solves the misalignment problem of circular steel structure models during the assembly process and can flexibly reserve transportation channels to transport sub-modules, thereby facilitating the overall assembly of more sub-modules.

[0007] The circular steel structure module includes a plurality of submodules, and the plurality of submodules are connected in sequence to form a ring structure with an opening, and the second positioning structure is arranged at the opening.

[0008] The first positioning structure comprises a plurality of reinforced concrete piers arranged around the annular structure, wherein the inner and outer sides of a plurality of the submodules are respectively connected to the reinforced concrete piers.

[0009] The second positioning structure includes a plurality of column assemblies, and the column assemblies are detachably connected to the submodules;

[0010] The column assembly comprises two columns respectively arranged on the inner and outer sides of the annular structure, and a horizontal column fastened to two adjacent columns.

[0011] The third positioning structure includes a cable embedded part arranged outside the annular structure, a cable connected to the cable embedded part at one end, and the other end of the cable is fixedly connected to the outer side surface of one of the submodules.

[0012] The bottom end of the column is connected to a reserved anchor bolt arranged on the ground through a bolt.

[0013] The cable is fixed on the cable embedded part through a U-shaped clip.

[0014] The submodule connected to the reinforced concrete pier is connected to the cable.

[0015] The first positioning structure and the second positioning structure are fastened and connected via a drawstring.

[0016] The plurality of cable embedded parts are all located on a virtual circle, and the center of the virtual circle is located on the center of the circular steel structure module.

[0017] The utility model achieves the following significant effects:

[0018] (1) During the on-site assembly of circular steel structure modules, especially during the welding process, radial and circumferential offsets are very likely to occur, and it is difficult to adjust after the offset. This solution solves the offset of circular steel structure modules during the on-site assembly process to control and adjust the offset of circular steel structure modules.

[0019] (2) The key to this solution is to facilitate on-site assembly of the sub-models of the circular steel structure module.
