Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a simple bridge maintenance construction access road. Background Art

[0002] Modern bridge maintenance access roads are passageways built beneath bridges to facilitate the work of bridge maintenance personnel. With the acceleration of urbanization and the increasing number of bridges, bridge maintenance has become increasingly important. Traditionally, bridge maintenance personnel have used equipment such as hanging baskets or aerial work platforms to perform maintenance work, which poses safety risks and is inefficient.

[0003] Modern bridge maintenance walkways have solved this problem. These walkways can be constructed along the underside of a bridge, allowing maintenance personnel to more easily access the structure for inspection and maintenance. They also provide a relatively stable and safe working environment, reducing the risks associated with maintenance operations. The design of these walkways typically considers technical indicators such as load-bearing capacity, anti-slip properties, and shock absorption to ensure the safety of maintenance personnel and operational efficiency.

[0004] To address the above issues, Chinese utility model patent number CN214939257U proposes a maintenance and repair device for addition to existing concrete bridges. The device comprises a travel mechanism, a track system, a transverse channel, a vertical channel, a detachable maintenance platform, and a fixed electric hydraulic lifting device. The track system is fixed to both sides of the bridge deck, and the travel mechanism is mounted on the track system. The transverse channel spans the bottom of the bridge, with both ends fixedly connected to vertical channels, which are fixed to the travel mechanism on the corresponding side. The transverse channel is connected to a fixed electric hydraulic lifting device for repairing box girders without webs and a maintenance platform for inspecting the box girder bottom plate. The device is suitable for mobile maintenance and repair of concrete bridges with wide bridge widths and no bottom plates between the boxes. However, this maintenance and repair device, added to existing concrete bridges, lacks safety considerations. The smooth surface of the platform can easily cause workers to slip in rainy or humid environments, endangering their lives. Utility Model Content
