Problems solved by technology

[0003] Due to the product defects in the existing technology itself, there are the following deficiencies: one is that although the mud discharge rubber pipe has a certain bending performance, because the curvature of the direction of the mud discharge pipeline is adjusted, it depends on the whole body from inside to outside. The deformation scheme is realized. For the self-floating mud discharge rubber pipe, this deformation is completed by the elastic deformation of each part of the pipe body, and the elastic deformation of each part is for the same circumferential section of the pipe body. There are dual stresses of tension and compression, so this technical solution itself has the problem that in the absence of external bending force, the elastic deformation of the self-floating mud discharge rubber pipe itself cannot guarantee to meet the specified bending degree. The defects of the requirements, especially the non-matching defects shown when it is used with the bundled floating metal mud discharge pipe are more prominent; The technical solution of grinding the steel ring is to improve the wear resistance of the rubber pipe. When the mud discharge rubber pipe is in use, the solid material to be transported is repeated in a conveying pipeline composed of an organic adhesive and a wear-resistant steel ring. Running, because the inner wall made of organic adhesive and wear-resistant steel ring will be repeatedly collided by solid materials, the degree of wear of organic adhesive and wear-resistant steel ring is not the same, which will not only affect the conveying speed due to conveying resistance, but also directly It affects the service life. Due to the inconsistent wear resistance of the inner pipe wall, it is difficult to use it with a better metal composite mud discharge pipe, especially in the operation of transporting ore and coral reefs in the South China Sea under harsher operating conditions. The matching phenomenon is more prominent

Abstract

The invention discloses a full-armor mud discharging pipe, a production method and a special device of the full-armor mud discharging pipe and belongs to the technical field of dredging engineering equipment. According to the technical scheme, the full-armor mud discharging pipe comprises a pipe body and a connecting and fastening layer combined to the outer side of the pipe body; the full-armor mud discharging pipe is characterized in that an inlet end joint pipe, tapered pipes and an outlet end joint pipe are sequentially assembled into a whole in an armored manner to form the pipe body and are each at least formed by combing an inner steel pipe layer and an outer steel pipe layer, and at least two annular locating and fastening rings are arranged on the outer side wall of each outer steel pipe layer; and each connecting and fastening layer is sequentially wrapped with a strengthened elastic material layer, a multi-layer steel fastening layer and an elastic material layer. Compared with the prior art, the full-armor mud discharging pipe, the production method and the special device have remarkable improvements and the prominent substantive distinguishing features that the technical scheme is reliable, the bending requirement for adjusting the direction of the mud discharging pipe is met, and the wear resistance of the full-armor mud discharging pipe can be close to that of a metal composite mud discharging pipe, and the use performance of the metal mud discharging pipe is improved comprehensively.

Description

technical field [0001] The invention relates to the technical field of related equipment used in dredging engineering, in particular to the technical field of a production method of a full-armor 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 to the shutdown of the entire dredging engineerin...
