Gravel bed leveling and locking backfill are two important construction processes in the field of immersed tube tunnel construction,and their work efficiency and construction accuracy have a significant impact on the installation period of immersed tubes.Therefore,a feeding and locking backfill ship was designed and constructed that integrates feeding,locking backfill,and quality inspection.It simplifies the construction process of immersed tube tunnel,reduces equipment cost investment,and improves construction efficiency.In this paper,the application effect of locking and backfill ship for feeding materials was described in detail,which can provide reference for similar projects.
