Shallow sea reclamation area submarine pipeline protection device

The utility model relates to a shallow sea reclamation area submarine pipeline protection device. The shallow sea reclamation area submarine pipeline protection device is characterized in that the shallow sea reclamation area submarine pipeline protection device mainly comprises vertical piles, inclined piles, crossbeams, longitudinal beams and cover slabs, wherein the vertical piles are distributed at both sides of a submarine pipeline in a reclamation area, and moreover, at least one row of vertical piles are arranged by each side of the submarine pipeline; the shallow sea reclamation area submarine pipeline protection device is arranged in the form of steps along the pipeline direction by taking a steel body as a starting point and rises step by step; a group of inclined piles are arranged at intervals on the outmost vertical piles; the crossbeams are laid on the tops of the vertical piles along the direction perpendicular to the pipeline by means of fasteners; the longitudinal beams are laid on the upper surfaces of the crossbeams along the direction of the submarine pipeline by means of fasteners. The adoption of the protective structure ensures that the load on the top of the pipeline is in stepped stage-by-stage transition, so that the load applied on the pipeline between original surface load outside a construction area and overall reclamation load in the construction area can be in uniform transition, and thereby the shallow sea reclamation area submarine pipeline protection device can effectively ensure that the pipeline cannot be severely bent to break through the ultimate stress to be damaged.
