AI Technical Summary
The existing track support device for bridge erecting machines at docks is difficult to avoid the installation location of precast components while providing stable support, resulting in slow construction progress and easy spatial conflict with the protruding steel bars of reinforced concrete structures, which can damage the foundation structure.
The main body adopts a double-row support device, which consists of a frame system composed of columns, crossbars, diagonal braces, steel plates and bolts. The load is directly transmitted through bolted connections, avoiding the protruding steel bars of the reinforced concrete structure, thus ensuring track stability and uniform load distribution.
This achieved uniform load distribution, avoided local overload of the foundation structure, ensured the safe operation of the bridge erecting machine and the smooth installation of prefabricated components, and reduced the impact on existing projects.
