Description

Self-floating rubber pipe externally coated with ultra-high molecular PE (polyethylene) for dredging

Technical Field

The utility model relates to a dredging rubber tube in the pipeline equipment of the dredging industry, in particular to a self-floating rubber tube dredged by covering ultra-high molecular PE.

Background

The dredging hose is one of the necessary devices in the pipeline device of the dredging industry, the dredging self-floating hose is widely used, and in many ocean dredging projects, although the dredging self-floating hose has many advantages, the following problems still exist: (1) The outer coating is damaged due to collision of external working conditions and dragging during installation, and the outer reinforcing layer of the self-floating rubber pipe is broken off in severe cases to expose the inner floating body layer, so that the use of the pipeline is influenced; (2) After the self-floating rubber tube uses a period, a large amount of marine organisms (like the spiral shell, shells class) adsorb on the body surface, cause whole pipeline floating performance to descend, consequently when in-service use, mostly regularly adopt manual method to clear away, but marine organisms are stronger to the adsorptivity of self-floating pipe extexine, it just can clear away to spend a large amount of manpower and material resources, it takes a lot of work and time, therefore how better protection is from the outer coating of floating rubber tube, increase life, alleviate marine organism's adsorption efficiency, it becomes the technical problem who waits to solve urgently to reduce the pipeline maintenance cost.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a can wear-resistantly, tear-resistant, can alleviate marine organism adsorptivity simultaneously again from floating rubber tube to increase of service life, reduction maintenance cost, with this satisfy with adapt to the outer super high molecule PE of covering of the demand of the continuous development's dredging industry dredge from floating rubber tube.

In order to solve the technical problem, the utility model discloses an outer super high molecule PE that covers dredges from floating rubber tube, including one section rubber conduit and the pipe joint of setting at the rubber conduit both ends, the rubber conduit is by interior and outer including the inner liner, the winding is at the inner reinforcement layer in the inner liner outside, cover the well glue film in the enhancement layer outside including pasting, the body layer in the glue film outside is wrapped up in, cover the transition layer of pasting in the body layer outside, the winding is at the outer enhancement layer in the transition layer outside, cover the rubber layer of pasting on the outer enhancement layer and cover the wear-resisting PE panel of super high molecule in the rubber layer outside in order to form the PE outer coating.

The thickness of the PE outer coating is 3-10mm.

The PE outer coating is spirally wound on the outer surface of the rubber layer.

The lining layer is vulcanized rubber mainly comprising natural rubber and styrene-butadiene rubber.

The inner reinforcement layer and the outer reinforcement layer are formed by winding a plurality of layers of rubberized polyester cord fabrics or steel wire cord fabrics in a crossed manner.

The floating body layer is formed by winding a plurality of layers of closed-cell PE foam.

The utility model has the advantages that:

the special structural design of the PE outer coating is formed by the ultra-high molecular wear-resistant PE plate, so that the outer coating has more excellent wear resistance, water resistance and ageing resistance, the pipe body can be effectively protected, the accidental damage of the pipe body can be prevented, the PE material has good toughness, and the good bending performance of the self-floating rubber pipe can be ensured; on the more important aspect, the ultra-high molecular wear-resistant PE plate is covered on the outer side of the rubber layer to form the PE outer coating, the rubber layer has good elasticity, impact of the outside on the surface ultra-high molecular PE is further effectively delayed, and the service life is greatly prolonged.
