What is the standard procedure for railway shoulder replacement?

The standard process for rail shoulder replacement includes the following steps:
On-site investigation and planning: Conduct on-site investigation and assessment of the railway rail shoulders that need to be replaced, and determine the specific construction plan and time plan.
Construction preparation: Based on the on-site survey results, prepare the required personnel, materials, equipment and construction tools, and conduct safety education and training.
Old rail shoulder removal: Use professional tools to remove the old rail shoulder, paying attention to protecting the normal operation of the railway line.
New rail shoulder installation: Install the new rail shoulder as required, ensuring that its position, angle, size, etc. comply with relevant standards and requirements.
Adjustment and inspection: Adjust and inspect the new rail shoulder to ensure that its position, size, flatness, etc. meet the requirements, and carry out necessary reinforcement and stabilization measures.
Acceptance and debugging: After completing the installation of the new rail shoulder, acceptance and debugging will be carried out to ensure the normal operation, safety and reliability of the railway line.
Cleaning and restoration: Clean and restore the construction site to ensure that the normal use and safety of the railway lines are not affected.
It should be noted that during the process of replacing railway rail shoulders, relevant safety regulations and operating procedures must be followed to ensure construction safety and quality. At the same time, it is necessary to minimize the impact on the normal operation of railway lines and reasonably arrange construction time and plans.
