T/GXHS 001-2023 Highway transportation technical guidelines for large components on bridge over highways

Scope

Main technical content: (1) Clarify the requirements and evaluation indicators for the transportation of large-scale components of highway bridges by people, goods, and vehicles. Firstly, starting from the transportation of large-scale components of highway bridges, clarify the definition of large-scale components of highway projects and their quality requirements, dimensional requirements, and factory production requirements. Then, clarify various indicators such as the drivers, transportation vehicles, transportation management, transportation preparation, and the service level of highways for the carriers of large-scale components of highway projects. The unification of evaluation methods for components and carriers is conducive to the scientific and standardized management of engineering projects. (2) Clarify the traffic requirements and evaluation indicators for the transportation of large-scale components of highway bridges. Systematically investigate and study the objective conditions of roads involved in the transportation process between the station sites and construction sites of Guangxi highway projects, including climate conditions, traffic routes, road conditions, transportation distances, traffic periods, speeds, exiting and entering highways and ramps, interchanges, toll stations, and maintenance and parking. Clarify the detailed rules and evaluation indicators of the above projects. (3) Clarify the monitoring content and sampling methods for the bridge and road conditions during the transportation of large-scale components of highway bridges. On the one hand, the transportation of large-scale components will have different impacts on different structures of bridges. The safety monitoring of structures should focus on checking the abnormal deformation of the superstructure, the increase in deformation of piers and abutments, and the damage to bearings according to the specific conditions of the bridge. On the other hand, during the vehicle trans
