Description

There is the lined Prestressed concrete cylinder pipe of the full anticorrosive coat of fiberglass

Technical field

This utility model is related to a kind of pipe of concrete, especially a kind of lined prestressing force with the full anticorrosive coat of fiberglass Cylinder concrete pipe.

Background technology

At present, Prestressed concrete cylinder pipe (abbreviation pccp), is a kind of new rigid pressure tubing.It is with steel Cylinder strong concrete tube core be wound around compressor wire, spray with cement mortar protective course, using steel bell and spigot steel loop and with Steel cylinder is welded into one, and the fluted O-ring seal of bell and spigot band defines the flexible joint of slidingtype cushion rubber, be steel plate, concrete, High tensile steel wire and the composite construction of cement mortar different materials composition, have steel and the respective characteristic of concrete.Prestress steel Cylinder pipe of concrete has and bears that interior external pressure is high, joint tighness is good, shock resistance is strong, it is convenient and swift to apply, antiseptic property is good, ties up The characteristic such as shield is convenient, of interest by engineering circles, be mainly used in long distance water transfer main line, pressure inverted-siphon, urban water supply engineering, Pressure water conveyer pipeline, electric power plant circulating water engineering pipeline, pressure blowdown main etc..Compared with conventional tubing, have applied widely, Economic life length, anti-seismic performance be good, easy for installation, it is low to run expenditure, the advantages of substantially water-tight.Prestressed concrete cylinder pipe Two kinds can be divided into from structural shape: a kind of is lined Prestressed concrete cylinder pipe (pccpl), that is, in steel cylinder inwall molding Concrete, is directly wound around ring orientation prestress steel wire outside steel cylinder, then gunite protective layer and the pipeline made；One Planting is embed-type Prestressed concrete cylinder pipe (pccpe), is to be embedded in inside tube core concrete by steel cylinder, then mixes in tube core It is wound around gunite protective layer after ring orientation prestress steel wire on solidifying soil outer wall.

But as the concrete component product being embedded in soil environment, in soil environment, if pre-stress steel cylinder Pipe of concrete does not take the measure of being effectively protected, with the prolongation of use time, the soil of Prestressed concrete cylinder pipe outer wall Corrosive medium in environment and in aqueous medium in pipe invades mortar cover and coagulation in Prestressed concrete cylinder pipe Soil layer, reaches steel wire and steel cylinder surface, then steel wire and steel cylinder will occur electrochemical corrosion, and then can lead to steel wire and steel cylinder Corrosion failure, occur perforation to reveal even booster phenomenon, cause a hidden trouble to the safe operation of tubing, directly threaten and manage The etching problem of the operational reliability of road system, wherein compressor wire and steel cylinder be impact works durability main because Element, if there is breakage because of corrosion in steel wire and steel cylinder, it will directly result in the corrosion failure of Prestressed concrete cylinder pipe, from And affect the safe operation of whole tubing.As can be seen here Prestressed concrete cylinder pipe very must using anti-corrosion measure Will, the bell and spigot steel loop of prestressed concrete pipe is directly exposed simultaneously does not have the protection of concrete layer outside, pre- as two The surface of the junction of prestressed concrete pipe, the bellmouth steel loop of prestressed concrete pipe and the socket steel ring of prestressed concrete pipe Protect particularly important, the operational reliability of this direct threat tube system, thus affecting the safe operation of whole tubing, because The bellmouth steel loop at the outer surface of this Prestressed concrete cylinder pipe and two ends and socket steel ring process for treating surface are extremely necessary.

Current Prestressed concrete cylinder pipe technology has the disadvantage in that

The bellmouth steel loop at Prestressed concrete cylinder pipe two ends domestic at present and socket steel ring surface are only on surface The simple epoxy resin coating of application, antiseptic effect is undesirable, when corrosive medium corrodes Prestressed concrete cylinder pipe two ends Bellmouth steel loop and common epoxy coating during socket steel ring surface be unable to effective protection Prestressed concrete cylinder pipe two ends Bellmouth steel loop and socket steel ring surface, and then corrosive medium can be led to corrode the bellmouth at Prestressed concrete cylinder pipe two ends Steel loop and socket steel ring surface, simultaneously domestic at present Prestressed concrete cylinder pipe surface mostly is spraying cement mortar cover, Outer layer does epoxy coal tar pitch coating, and cement mortar quality is loose, breakage of easily colliding with when mounted, and extraneous medium is held Easily penetrate into compressor wire and steel cylinder surface, cause steel wire and steel cylinder corrosion, bring hidden danger to the safe operation of pipeline.
