Abstract
The utility model provides a pair of power station pipeline under pressure's protective layer device through set up the protective layer device of compriseing rubber tie coat, waterproof layer, anticorrosive coating, asphalt concrete protective layer and steel fiber concrete protective layer outside pipeline under pressure, can effectively hinder slow pipeline under pressure's corrosion, improves power station pipeline under pressure's life.
Description
Technical field
This utility model relates to Hydraulic and Hydro-Power Engineering, in particular to the protective layer device of a kind of hydropower station pressure pipeline.
Background technology
Power station belongs to the one of Hydraulic and Hydro-Power Engineering building, and its majority is generated electricity by pressure pipeline diversion, and pressure
Pipeline many employings steel pipe form, along with adding up of the time of operation, the most easily there is the situations such as corrosion, serious meeting shadow in pressure pipeline
Ring normal diversion and the generating in power station.
For the protection of pressure pipeline, at present often through arranging concrete cover outside pipeline, and its protected effect is poor,
Pressure pipeline still there will be corrosion in various degree, and pressure pipeline carries out safeguarding replacing, the most costly.Therefore, carry
For the protective layer device of a kind of hydropower station pressure pipeline, there is certain engineer applied and be worth and economic benefit.
Summary of the invention
This utility model, by arranging corresponding protective layer device outside pressure pipeline, can effectively delay the rust of pressure pipeline
Erosion, improves its service life.
This utility model provides the protective layer device of a kind of hydropower station pressure pipeline, including the guarantor outside pressure pipeline and pressure pipeline
Sheath, it is characterised in that: described pressure pipeline is steel pipe, and described protective layer includes the rubber bound layer arranged from inside to outside, prevents
Water layer, anticorrosive coat, bituminous concrete protective layer, steel fiber reinforced concrete protective layer, described pressure pipeline is after rust cleaning, then sets
Putting rubber bound layer, described rubber bound layer thickness is not more than the 1% of pressure pipeline interior diameter, and described waterproof layer uses polyurethane,
Described anticorrosive coat uses epoxy zinc-rich paint, and described waterproofing layer thickness is 2 times of anticorrosive coat thickness, and anticorrosive coat thickness is manometer tube
The 1.5% of road thickness, described bituminous concrete protective layer thickness equal to described waterproof layer and described anticorrosive coat thickness and, and Colophonium
The strength grade of concrete is not less than C30, and described steel fiber reinforced concrete protective layer thickness is equal to the thickness of bituminous concrete protective layer,
The strength grade of described steel fiber reinforced concrete protective layer is not less than C25.
As preferably, described bituminous concrete is particulate formula bituminous concrete.
As preferably, the strength grade of described steel pipe is not less than Q235.
By above-mentioned setting, can effectively hinder the corrosion of slow pressure pipeline, improve its service life.

Detailed description of the invention
Below as a example by specific embodiment, this utility model is briefly described.
This utility model provides the protective layer device of a kind of hydropower station pressure pipeline, including the guarantor outside pressure pipeline and pressure pipeline
Sheath, it is characterised in that: described pressure pipeline is steel pipe 1, rubber bound layer 2 that described protective layer includes arranging from inside to outside,
Waterproof layer 3, anticorrosive coat 4, bituminous concrete protective layer 5, steel fiber reinforced concrete protective layer 6, described pressure pipeline is through rust cleaning
After, then rubber bound layer 2 is set, described rubber bound layer 2 thickness is not more than in pressure pipeline the 2% of interior diameter, described waterproof
Layer 3 uses polyurethane, and described anticorrosive coat 4 uses epoxy zinc-rich paint, described waterproof layer 3 thickness to be 2 times of anticorrosive coat 4 thickness,
And anticorrosive coat 4 thickness is the 1.5% of pressure pipeline interior diameter, described bituminous concrete protective layer 5 thickness is equal to described waterproof layer 3
With described anticorrosive coat 4 thickness and, and the strength grade of bituminous concrete is not less than C30, described steel fiber reinforced concrete protective layer
6 thickness are equal to the thickness of bituminous concrete protective layer 5, and the strength grade of described steel fiber reinforced concrete protective layer 6 is not less than C25.
As preferably, described bituminous concrete is particulate formula bituminous concrete.
As preferably, the strength grade of described steel pipe 1 is not less than Q235.
By arranging above-mentioned protective layer device outside pressure pipeline, can effectively delay the corrosion of pressure pipeline, improve it and make
Use the life-span.
Below being only preferred embodiment of the present utility model, any technical scheme without departing from present inventive concept all should be in this practicality
In novel concrete protection domain.
