Description

A kind of aqueduct with antiseptic property

Technical field

The utility model belongs to water transferring line technical field, more particularly to a kind of aqueduct with antiseptic property.

Background technology

In water conservancy construction, water-supply-pipe is necessary construction material, and because water-supply-pipe needs are buried in underground, pipeline makes Environment is intricate, conveys in soil environment of the pipeline of water mostly in complexity, and the medium for being conveyed also more corrosion Property, thus inner-walls of duct and outer wall may all be corroded, the perforation once pipeline is corroded causes the leakage of water, not only makes Traffic interruptions, and polluting the environment, in some instances it may even be possible to cause other disasters, cause harm, pipeline corrosion protection be divided into main body anti-corrosion and Repaired mouth, pipe main body anti-corrosion can improve the service life of pipeline, improve the security of hydraulic engineering.

Utility model content

The utility model provides a kind of aqueduct with antiseptic property, is easily corroded with solving pipeline in the prior art The problem of perforation.

To achieve the above object, the technical solution adopted in the utility model is：

A kind of aqueduct with antiseptic property, including hollow body, the inner and outer surfaces of the body are coated with anti- Rotten layer, the anticorrosive coat outside of body inner and outer surfaces is coated with external protection, and the external protection includes outer layer and bottom, institute State anticorrosive coat outside to be fitted with outer layer by bottom, the anticorrosive coat is solvent-free liquid epoxy coating, the outer layer is radiation Crosslinked polyethylene shrink belt, the bottom is gluing oxidant layer.

Further, thickness of the inner surface of tube body anticorrosive coat thickness less than surface corrosion-resistant layer cleaner.

Further, the thickness of the external protection is 5-10mm.

Further, thickness of the outer layer thickness of the external protection more than or equal to bottom.

Further, the thickness of dry film of the solvent-free liquid epoxy coating is 600 ± 50 μm.

Further, the outer layer makees dried shrimps shape overlap joint cladding, the radiation using radiant crosslinked polyethylene heat shrinkable band Crosslinked polyethylene shrink belt thickness >=2.2mm, lap width is the 10-15% of radiant crosslinked polyethylene heat shrinkable bandwidth.

Further, the body is hollow cylinder body, and the material of the body is steel.

Compared with prior art, the utility model has advantages below：

1st, solvent-free liquid epoxy coating and steel tube surface caking property are excellent, anti-chemical mediator corrodes, antiseptic property is good, the moon Pole disbondment radius is small, temperature in use scope is wide, normal temperature solidified, construction safety environmental protection；

2nd, radiant crosslinked polyethylene heat shrinkable band shock resistance, mechanical resistant scratch resistant are strong, should with good anti-soil Power is acted on.

3rd, aqueduct of the present utility model can guarantee that the integrality of pipeline anticorrosion coating, improve the safety of conduit running Property, reliability.

Specific embodiment

The utility model is further described with reference to embodiment.

As shown in figure 1, a kind of aqueduct with antiseptic property, including material is the hollow cylinder body 1 of steel, bag Hollow body is included, the inner and outer surfaces of the body 1 are coated with anticorrosive coat 2, and the outside of anticorrosive coat 2 of the inner and outer surfaces of body 1 is External protection 3 is coated with, the external protection 3 includes outer layer and bottom, and the outside of the anticorrosive coat 2 is by bottom 31 and outer layer 32 Laminating, the anticorrosive coat 2 is solvent-free liquid epoxy coating, and the outer layer 32 is radiant crosslinked polyethylene heat shrinkable band, described Bottom 31 is gluing oxidant layer.

Thickness of the thickness of 1 inner surface anticorrosive coat of the body 2 less than surface corrosion-resistant layer cleaner 2；The thickness of the external protection 3 Be 5-10mm, and external protection 3 thickness of the thickness of outer layer 32 more than or equal to bottom 31, the thickness of the external protection 3 is preferred It is 6mm；The thickness of dry film of the solvent-free liquid epoxy coating is 600 ± 50 μm.

The outer layer makees dried shrimps shape overlap joint cladding using radiant crosslinked polyethylene heat shrinkable band, and dried shrimps shape overlap joint is commonly called as dried shrimp Curved, i.e. in the middle part of prawn, the length pipe by not waiting cuts and is bent pipeline the curvilinear portion class of metallic conduit, the radiation Crosslinked polyethylene shrink belt thickness >=2.2mm, lap width is the 10-15% of radiant crosslinked polyethylene heat shrinkable bandwidth.

Solvent-free liquid epoxy coating, radiant crosslinked polyethylene heat shrinkable band and the adhesive used in the utility model are equal Belong to current material, the adhesive is at normal temperatures solid-state, and heating is melt into liquid, after coating adherend, through pressing, cooling Form layer structure.

The above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
