Armored sludge pipe design method and sludge pipe thereof

Abstract

The invention discloses an armored sludge pipe design method and a sludge pipe thereof, and belongs to the technical field of dredging engineering equipment. The technical scheme includes that the armored sludge pipe design method includes overall design for an armored pipe body and flange plates at two ends of the pipe body and specific design for parts. The armored sludge pipe design method is characterized in that the technical requirement that the curvature of the armored sludge pipe is larger than or equal to 35 degrees is met, a plurality of armored pipe body conical inner pipes and armored pipe body outer pipes are connected in a bolt-on manner to form an armored pipe body unit, and the armored sludge pipe comprises the armored pipe body unit and the flange plates at the two ends. Compared with the prior art, the armored sludge pipe design method has the outstanding substantial advantages and the remarkable progress that the technical scheme is reliable, the bending requirement for adjusting the direction of the sludge pipe is met, the abrasion resistance of the sludge pipe can be closer to that of a metal composite sludge pipe, and the service performance of the metal sludge pipe is comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of related equipment used in dredging engineering, in particular to a design method of an armored mud discharge pipe used in dredging engineering and the technical field of the mud discharge pipe. Background technique [0002] Mechanical dredging projects such as river courses, waterways, harbor basin dredging, harbor shoals, and wharf foundation trenches all require a large number of mud discharge pipelines connected by mud discharge pipes to achieve transportation, and the indispensable part of the entire mud discharge pipeline is used to adjust The mud discharge elbow in the direction of the mud discharge pipeline, most of the self-floating mud discharge rubber pipes that have been used so far, because the self-floating mud discharge rubber pipe is very fast when transporting solid materials with sharp edges such as rocks, coral reefs, ores, etc. It will be worn out and lose its use value, which will lead...

AI Technical Summary

Problems solved by technology

However, due to the inherent defects of the self-floating mud discharge rubber pipe itself, there are still the following deficiencies: one is that although the self-floating mud discharge rubber pipe has a certain bending performance, it is used as a mud discharge elbow There are still obvious inherent deficiencies in the function of adjusting the direction of the mud discharge pipeline, especially when it is used in conjunction with the bundled floating metal mud discharge pipe; the second is that the self-floating mud discharge rubber pipe passes through the The technical solution of adding organic adhesive and wear-resistant steel ring to the innermost layer of the rubber hose can improve the wear resistance of the rubber hose itself. There is still a considerable gap in cost and other aspects; the third is that the outer layer of the self-floating mud discharge rubber pipe is made of rubber material. If it is used in harsh environments such as transporting rocks, coral reefs, etc. The work site will be torn soon, and once it is broken and cannot be used, it will inevitably cause shutdown; therefore, how to design and manufacture an armored mud discharge pipe on the basis of the existing technology can meet the purpose of adjusting the direction of the mud discharge pipeline At the same time, it can achieve the same wear resistance as the metal composite mud discharge pipe, comprehensively improve the use quality, service life and adaptability of the metal mud discharge pipe, reduce the production cost of the dredging project, and improve the economic benefits of the enterprise. Still a problem to be solved urgently for those skilled in the art
