Comparative Study on Design and Construction Methodology of Precast Box Type Road Under Bridge by Box Pushing Techniques Using PTFE Sheet
摘要
The work to be done for the expansion of current streets using box pushing is outlined in the project named analysis and plan and execution of cross traffic works in railroads utilizing box pushing method (RUB).methods for the rail beneath the scaffolds. It also explains the approach used in the box pushing strategy’s execution. The strategy will be executed in compliance with Indian models, namely the Indian railroad regulations and the IRC, IRS, and IS CODESwhereby the precast box used for the extending and the plan of major components push bed are completed in accordance with IRS rules. The pre-thrown box design is completed using STAAD genius. It also includes the format of support details of two important structures that are used in this approach apart from the conventional method, namely the push bed (principal bed and helper bed) and the pre-thrown box. In railroads, underpasses must be built whenever necessary, whether for a canal crossing, RUBs (rail under scaffolds), a program to enlarge already-existing rail route ducts, etc. The technique of BOX PUSHING is applied. In contrast to conventional approaches, the box pushing strategy is often favored as the job must be managed without interfering with train traffic. Due to rapid advancements, the volume of traffic on both the rail and road nowadays is so great that old methods, such open-cut framework, are unable to keep up with the expansion of underpasses or canal crossings, trash, and other issues. Box Pushing Technique: R.C.C. boxes are partially thrown outdoors and pushed by jacking through the massive banks of rail or road.
