Abstract
The utility model discloses a PCCPL with a thermal spraying pure zinc coating on a steel cylinder. The PCCPL comprises an inner concrete layer, the steel cylinder and an outer cement mortar protective layer which are sequentially arranged from inside to outside, wherein a corrosion preventive coating is arranged on the outer wall of the steel cylinder and prestressed wires are wound outside the corrosion preventive coating. According to the PCCPL, the whole structure is quite simple, the design is scientific and reasonable, good durability and corrosion resistance are provided, the manufacturing process is simple, and the service life of the whole PCCPL is prolonged effectively due to the steel cylinder after the process of the thermal spraying pure zinc coating.
Description
Technical field
The utility model belongs to the prestressed concrete member field, the lined Prestressed concrete cylinder pipe of the pure spelter coating of especially a kind of steel cylinder band thermal spraying.
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 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 is 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 widelyly, the economic life is long, anti-seismic performance good, easy for installation, the advantage such as the operation expenditure is low, and is 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, especially the steel cylinder as critical piece in the Prestressed concrete cylinder pipe has no the document of taking protective coating on the surface abroad.
There is following shortcoming in present Prestressed concrete cylinder pipe technology:
The main member steel cylinder of at present domestic Prestressed concrete cylinder pipe inside does not carry out cover coat to be processed; when corroding the steel cylinder surface, corrosive medium can not effectively protect steel cylinder; and then can cause the corrosion failure of steel cylinder, 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 is processed for the main member steel cylinder that overcomes above-mentioned existing lined Prestressed concrete cylinder pipe inside, a kind of lined Prestressed concrete cylinder pipe of simple in structure, the pure spelter coating of steel cylinder band thermal spraying is provided, can effectively prolongs 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 of the pure spelter coating of a kind of steel cylinder band thermal spraying; comprise the internal layer concrete layer, steel cylinder, the outer cement mortar protective course that set gradually from inside to outside; described steel cylinder outer wall is provided with corrosion resistant coating, and the outside of corrosion resistant coating is wound with reinforcement wire.
Described corrosion resistant coating is pure spelter coating, and pure spelter coating is sprayed directly on the steel cylinder by electric arc spraying.
The utility model adopts and first pure spelter coating is sprayed directly on the steel cylinder by electric arc spraying, then twines reinforcement wire at steel cylinder, sprays at last outer cement mortar protective course.
The steel cylinder surface coating of critical piece is 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, especially cladding technique extremely is necessary.
The utlity model has following beneficial effect:
1, passes through the pure spelter coating of the electric arc spraying of steel cylinder outer surface at the utility model; for improving, the antiseptic property of lined Prestressed concrete cylinder pipe increased together important barrier; when corroding the steel cylinder surface, corrosive medium can effectively protect steel cylinder; simultaneously because the current potential of zinc is more negative than the current potential of iron; pure spelter coating can also play the effect of sacrificial anode simultaneously; angle from electrochemical protection; the effect of more effective performance electrochemical protection lined Prestressed concrete cylinder pipe, it is convenient to use.
2, the utility model overall structure is very simple, design science is reasonable, have good durability, corrosion resistance, and manufacturing process is simple, the steel cylinder of the pure zinc of process electric arc spraying is the higher lined Prestressed concrete cylinder pipe of a kind of novelty so that the life-span of whole lined Prestressed concrete cylinder pipe effectively prolongs.
