Code for traffic organization design of expressway reconstruction and expansion the purpose of traffic organization design of expressway reconstruction and expansion is to ensure safe and orderly traffic operation during reconstruction and expansion, facilitate the smooth implementation of reconstruction and expansion projects, and control the social impact of project construction on traffic.

This specification is applicable to the traffic organization design in the stages of feasibility study, design and construction of expressway reconstruction and expansion project.

This specification summarizes the engineering experience and relevant scientific research achievements in the manufacturing, installation and construction of steel structure bridges at home and abroad in recent years, and absorbs the mature technologies and processes; Emphasis should be placed on the maturity of technology and technology, with regard to the advanced nature.

The appendices are the design requirements of lifting point, material performance of reactive powder concrete and socket connection between circular pipe pier and bearing platform.

The design of expressway reconstruction and expansion project itself and the design scheme of traffic organization need to be unified and given consideration to each other.

This specification includes 15 chapters and 7 appendices, including: 1 general, 2 terms and symbols, 3 survey and measurement, 4 building materials, 5 overall design, 6 structural design, 7 drilling and blasting tunnel, 8 shield tunnel, 9 immersed tunnel, 10 weir tunnel, 11 ancillary works, 12 drainage system, 13 traffic engineering facilities and disaster prevention and rescue, 14 risk analysis, 15 structural safety monitoring, Appendix A: classification of construction conditions of highway underwater tunnel, Appendix B: environmental action level of highway underwater tunnel, Appendix C: Calculation of crack width of reinforced concrete structural members, Appendix D: Calculation of bearing capacity limit state of reinforced concrete structural members, Appendix E: Waterproof classification and fortification requirements of highway underwater tunnel structure Appendix F: configuration table of fire fighting and monitoring facilities for highway underwater tunnel, appendix G: judgment standard of risk event loss level.

The specification includes 8 chapters and 3 appendices, which are respectively: 1 general, 2 terminology, 3 investigation, analysis and traffic volume prediction, 4 overall design of traffic organization, 5 regional road network diversion, 6 traffic organization of Baotong road section, 7 traffic organization in emergency, 8 supporting facilities of traffic organization, Appendix A: calculation method of traffic capacity in operation area, Appendix B: preparation outline of special research report on traffic organization scheme, Appendix C: calculation method of traffic tolerance, detour and node importance.

This specification is applicable to the design of highway cast concrete beam bridges.

This specification contains seven chapters and three appendices, which are general provisions, terms and symbols, basic provisions, materials, superstructure, substructure and seismic design.

Emphasize the control of key processes and key technical processes, and clarify the guidelines and technical quality requirements that should be observed in the manufacturing, installation and construction of steel structure bridges; Learn from the relevant technical standards for manufacturing and installation of steel structure bridges at home and abroad; Coordinate with relevant standards, specifications and procedures..

Click “road lookout” above the king point → click “…” in the upper right corner → click “set as star standard ★” recently, the Ministry of transport issued four industry standards.

Different from new projects, expressway reconstruction and expansion projects need to take into account the needs of construction and traffic protection.

The version of highwayoutlook wechat has been revised again.

The traffic organization scheme will affect the reconstruction and expansion design scheme and construction scheme of the main project.

The demand of Baotong will sometimes become an important factor affecting the overall scheme of reconstruction and expansion, so it must be comprehensively considered in the stages of feasibility study, design and construction.

Therefore, the traffic organization design must be considered in the overall design scheme of reconstruction and expansion.

Many new friends say they can’t find the road.
