The embedded prestressed steel cylinder concrete pipe comprises a cylinder part and a pipe socket steel ring and a plug socket steel ring which are respectively arranged at both ends of the cylinder part, wherein the cylinder part sequentially comprises an epoxy closing layer, a steel cylinder inner wall concrete layer, a steel cylinder, a steel cylinder outer wall concrete layer and a cement mortar protective layer from inside to outside; and a prestressed steel wire is wound on the outer surface of the steel cylinder outer wall concrete layer. Meanwhile, the invention also discloses components and a manufacturing method of the epoxy closing layer. The concrete pipe is simple in structure, and can effectively prevent substances in the concrete layers from being dissolved in water and prevent the concrete layers from being destroyed, thus providing guarantee for the safe operation of water transmission through a water transmission pipeline.
Description
Technical field
The present invention relates to a kind of prestressed concrete member, especially a kind of inwall has the embed-type Prestressed concrete cylinder pipe of epoxy protective layer.
Background technique
At present, Prestressed concrete cylinder pipe (being called for short PCCP) is a kind of novel rigid pressure tubing.It is the strong concrete tube core winding reinforcement wire with steel cylinder; spray is with cement mortar protective course; adopt steel bell and spigot and be welded into one with steel cylinder; the fluted O-ring seal of joint socket band defines the flexible joint of sliding type cushion rubber; be the composite structure of steel plate, concrete, High Tensile Steel Wire and slush different materials composition, there is steel and concrete characteristic separately.Prestressed concrete cylinder pipe has and bears the characteristics such as interior external pressure is high, joint tighness good, shock resistance is strong, it is convenient and swift to execute, antiseptic property good, easy to maintenance, 's pay close attention to by engineering circles, be mainly used in long distance water transfer main line, pressure inverted-siphon, town water supply engineering, pressure water conveyer pipeline, electric power plant circulating water engineering pipeline, pressure blowdown main etc.Compared with tubing in the past, advantages such as having applied widely, the economic life is long, anti-seismic performance good, easy for installation, to run expenditure low, substantially water-tight.Prestressed concrete cylinder pipe can be divided into two kinds from structural type: a kind of is lined Prestressed concrete cylinder pipe (PCCPL), namely at steel cylinder inwall formation of concrete, directly ring orientation prestress steel wire is wound around, then gunite protective layer and the pipeline made outside steel cylinder; One is embed-type Prestressed concrete cylinder pipe (PCCPE), is to be embedded in by steel cylinder inside tube core concrete, in tube core outer walls of concrete, be then wound around gunite protective layer after ring orientation prestress steel wire.
But as the concrete water transfer component product be embedded in edatope, what concrete pipe internal layer adopted is concrete layer structure, Prestressed concrete cylinder pipe is as waterline, due to water long-time stop in the duct with wash away, some materials inside concrete layer can be made to enter in water, have influence on water quality safety, in addition when water delivery seawater, because in seawater, chlorine ion concentration is high, the destruction of concrete layer can be aggravated equally, adopt anti-corrosion measure very necessary to the internal layer of Prestressed concrete cylinder pipe with outer as can be seen here.
There is following shortcoming in current Prestressed concrete cylinder pipe technology:
Prestressed concrete cylinder pipe internal layer concrete layer domestic does not at present have protective layer; water long-time stop in the duct and washing away; some materials inside concrete layer can be made to enter in water; have influence on water quality safety; the destruction of accelerate concrete layer, brings hidden danger to the safe operation of waterline water delivery.
Summary of the invention
The object of the invention is the technical deficiency for overcoming the process of above-mentioned existing embed-type Prestressed concrete cylinder pipe innermost surface; a kind of inwall is provided to have the embed-type Prestressed concrete cylinder pipe of epoxy protective layer; this concrete pipe structure is simple, can effectively prevent the material in concrete layer from dissolving in water.
For achieving the above object, the present invention adopts following technical proposals:
A kind of inwall has the embed-type Prestressed concrete cylinder pipe of epoxy protective layer; comprise shell portion; and be arranged at bellmouth steel loop and the socket steel ring at shell portion two ends; shell portion is followed successively by epoxy sealing layer, steel cylinder internal-wall concrete layer, steel cylinder, steel cylinder outer wall concrete layer and cement mortar protective course from inside to outside; wherein, the outer surface of steel cylinder outer wall concrete layer is wound with reinforcement wire.
Epoxy sealing layer comprises following component in mass ratio: epoxy resin 60 parts, titanium dioxide, 40 parts, ethyl acetate 3-8 part, German BYK dispersing agent 0.5 part, German BYK defoamer 0.3 part; Polyamide resin 50 parts, solvent is n-butanol 10 parts.
The 5:1 preparation in mass ratio of polyamide resin and n-butanol.
The making method of epoxy sealing layer is:
1) first added in stirrer by epoxy resin by formula ratio, then add n-butanol, titanium dioxide, ethyl acetate, German BYK dispersing agent and defoamer in order successively, mixing time is 30 minutes, obtains a component, takes out stand-by;
2) add as in stirrer by packing quality ratio successively by polyamide resin and n-butanol again, both mix and blends obtain b component in 10 minutes, take out stand-by;
3) by step 1) and step 2) a component that obtains and b component be that 20:1 adds stirrer by quality proportioning, mix and blend 30 minutes, leave standstill after 5 minutes, by spraying machine even application on the steel cylinder internal-wall concrete layer inwall of shell portion, coating thickness is 160um, spray three times, epoxy sealing layer can be accessed.
Steel cylinder internal-wall concrete layer, steel cylinder outer wall concrete layer and cement mortar protective course in the present invention are prior art, do not repeat them here.
Epoxy resin is as the film forming matter of main epoxy sealing layer, titanium dioxide is epoxy sealing layer filler, both constitute the main body of epoxy sealing layer, Germany's BYK dispersing agent and German BYK defoamer effectively can improve the uniformity of material in epoxy sealing layer, improve anticorrosion ability, and solvent is used for dissolved epoxy, the mixing of polyamide resin and n-butanol is as the curing agent of epoxy sealing layer, solidification effect is good, epoxy sealing layer can be made fast to solidify, effectively improve efficiency of construction.
The present invention has following beneficial effect:
1, innermost layer epoxy sealing protective layer of the present invention is the stripping that effectively inhibit material in concrete layer in embed-type Prestressed concrete cylinder pipe water delivery engineering, and for water delivery adds safely important barrier together, application is convenient.
2, overall structure of the present invention is very simple, and design science is reasonable, has good durability, impermeability, cracking resistance, corrosion resistance, and manufacturing process is simple, is the embed-type Prestressed concrete cylinder pipe that a kind of novelty is higher.
