Scope

Main technical content: On the basis of carefully summarizing the experience and scientific achievements of railway underpass projects of highway box culverts in China, conducting in-depth investigations and research, and widely soliciting opinions from relevant units and experts, the compilation team prepared this guide in accordance with the provisions of the "Guiding Principles for the Preparation of Technical Standards for Highway Engineering" (JTG A04-2013). The guiding ideology of this guide is to highlight the requirements of safety, quality, and environmental protection, and to comprehensively summarize the construction techniques of railway underpass projects of highway box culverts in recent years. The main technical content covers the entire construction process, with specific requirements for the protection and reinforcement of existing railway subgrade, the setting up of underpass facilities, the construction methods of underpass, and the key points of construction control during the process, highlighting the technical characteristics of railway underpass construction of highway box culverts. This guide is divided into 10 chapters and 1 appendix. The main contents include: 1. General Provisions, 2. Terms and Symbols, 3. Construction Preparation, 4. Protection and Reinforcement of Existing Railway Subgrade, 5. Work Pits, 6. Precast Box Culverts, 7. Underpass Facilities, 8. Box Culvert Underpass Construction, 9. Ancillary Construction, 10. Environmental Protection. The main technical content is as follows: 1.0.1 In order to standardize the construction process of railway underpass projects of highway box culverts, unify the technical standards of underpass construction, strengthen construction management, and ensure the quality and safety of the project, this technical guide is formulated. 1.0.2 This technical guide is applicable to the construction of railway underpass projects of highway box culverts. 1.0.3 The construction of railway underpass pr
