Description
Technical field
The utility model relates to a kind of prestressed concrete member, the lined Prestressed concrete cylinder pipe that especially a kind of steel cylinder steel wire has the pure spelter coating of thermal spraying, surface to process with the comprehensive anticorrosive of fibre crack-resistance screed and epoxy coal tar pitch coating.
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 the steel bell and spigot steel loop and be welded into one with steel cylinder; the fluted O-ring seal of joint socket band has formed the flexible joint of sliding type cushion rubber; be the composite structure that steel plate, concrete, High Tensile Steel Wire and slush different materials form, have 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, paid close attention to by engineering circles, be mainly used in long distance water transfer main line, pressure inverted-siphon, town water supply engineering, the waterline of pressure, electric power plant circulating water engineering pipeline, pressure blowdown main etc. are arranged.Compare with tubing in the past, have applied widely, the advantage such as the economic life is long, anti-seismic performance good, easy for installation, the operation expenditure is 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, the direct winding ring orientation prestress steel wire in steel cylinder outside, then gunite protective layer and the pipeline made; A kind of is embed-type Prestressed concrete cylinder pipe (PCCPE), is steel cylinder is embedded in tube core concrete the inside, then gunite protective layer after the tube core outer walls of concrete is twined the ring orientation prestress steel wire.
But as the concrete member product that is embedded in the edatope; in edatope; if Prestressed concrete cylinder pipe is not taked effective protective measure; prolongation along with service time; mortar cover and concrete layer in the corrosive medium intrusion Prestressed concrete cylinder pipe in the edatope of Prestressed concrete cylinder pipe outer wall and in the interior aqueous medium of pipe; arrive steel wire and steel cylinder surface; steel wire and steel cylinder will electrochemical corrosions so; and then can cause the corrosion failure of steel wire and steel cylinder; perforation occurs to be revealed even the booster phenomenon; can cause a hidden trouble to the safe operation of pipe-line system; the operational reliability of direct threat tube system; wherein the etching problem of reinforcement wire and steel cylinder is the principal element that affects the structure durability; if breakage occurs because of corrosion in steel wire and steel cylinder; will directly cause the corrosion failure of Prestressed concrete cylinder pipe, thereby affect the safe operation of whole pipe-line system.This shows and adopt anti-corrosion measure very necessary to Prestressed concrete cylinder pipe.
There is following shortcoming in present Prestressed concrete cylinder pipe technology:
The main member steel cylinder steel wire of at present domestic Prestressed concrete cylinder pipe inside does not carry out cover coat to be processed, and can not effectively protect steel cylinder when corrosive medium corrodes steel cylinder and Steel Wire Surface, and then can cause the corrosion failure of steel cylinder.Outer mortar cover anti-permeation cracking-resistant effect is undesirable simultaneously; the effective anti-permeation cracking-resistant of common mortar cover when corrosive medium corrodes Prestressed concrete cylinder pipe surperficial; and then can cause corrosive medium to corrode the surface of Prestressed concrete cylinder pipe, bring hidden danger for the safe operation of pipeline.
Summary of the invention
The purpose of this utility model is not carry out the technical deficiency that cover coat and surperficial anti-permeation cracking-resistant are processed for the main member steel cylinder that overcomes above-mentioned existing lined Prestressed concrete cylinder pipe inside and reinforcement wire; provide a kind of steel cylinder and the pure spelter coating of prestress steel silk ribbon thermal spraying, surface to have anti-permeation cracking-resistant mortar cover and outer surface that the lined Prestressed concrete cylinder pipe of epoxy coal tar pitch coating is arranged; this concrete pipe is simple in structure, can effectively prolong the working life of Prestressed concrete cylinder pipe.
For achieving the above object, the utility model adopts following technical proposals:
The lined Prestressed concrete cylinder pipe that a kind of comprehensive anticorrosive is processed; comprise shell portion; and the bellmouth steel loop and the socket steel ring that are arranged at the shell portion two ends; shell portion is followed successively by steel cylinder internal-wall concrete layer, steel cylinder, steel cylinder outer wall fibre anti-permeation cracking-resistant cement mortar protective course and outermost surface epoxy coal tar pitch coating from inside to outside; all be wound with reinforcement wire on the outer wall of steel cylinder and bellmouth steel loop, all scribble corrosion resistant coating on the outer surface of described steel cylinder outer surface and reinforcement wire.
Described corrosion resistant coating is pure spelter coating, and the pure spelter coating on the steel cylinder is sprayed directly on the steel cylinder outer wall by electric arc spraying.
Pure spelter coating on the described reinforcement wire adopts reinforcement wire in the outer wall process that is wrapped in steel cylinder and bellmouth steel loop, and the method for electric arc spraying makes while twining.
The composition of steel cylinder outer wall fibre anti-permeation cracking-resistant cement mortar protective course is to mix 1 kg polypropylene fiber in original every cubic metre of conventional cement mortar, and polypropylene fiber is of a size of 5mm to 10mm.
The utility model adopts first the steel cylinder outside is wound with reinforcement wire, twines the exposed outer wall of complete rear steel cylinder steel wire and directly makes pure spelter coating by electric arc spraying, sprays at last the fibre anti-permeation cracking-resistant cement mortar protective course.
The steel cylinder of critical piece and reinforcement wire surface coating are processed in the Prestressed concrete cylinder pipe, can further improve the whole antiseptic property of Prestressed concrete cylinder pipe, when corrosive medium corrodes the steel cylinder surface, coating can be used as together important defence line, Effective Raise Prestressed concrete cylinder pipe corrosion resistance, greatly prolong original life-span of Prestressed concrete cylinder pipe, so the process for treating surface of Prestressed concrete cylinder pipe the inside steel cylinder and reinforcement wire, and the preservative treatment technology of Prestressed concrete cylinder pipe outer surface extremely is necessary.
The utlity model has following beneficial effect:
1, the utility model is by the pure spelter coating of electric arc spraying to steel cylinder and reinforcement wire surface, the surface is with fibre crack-resistance screed and epoxy coal tar pitch coating, increased the important barrier in three roads for the antiseptic property of lined Prestressed concrete cylinder pipe improves, it is convenient to use.
2, the utility model overall structure is simple; design science is reasonable; have good durability, impermeability, cracking resistance, corrosion resistance; and manufacturing process is simple; through passing through the pure spelter coating of electric arc spraying to steel cylinder and reinforcement wire surface; cement mortar protective course adopts the processing of fibre anti-permeation cracking-resistant slush material and outer surface to have the epoxy coal tar pitch coating lined Prestressed concrete cylinder pipe life-span effectively to be prolonged simultaneously, is the higher lined Prestressed concrete cylinder pipe of a kind of novelty.
