Description
Technical field
The utility model relates to a kind of prestressed concrete member, and the bellmouth steel loop at especially a kind of Prestressed concrete cylinder pipe two ends, socket steel ring band and steel cylinder outer surface are all with the lined Prestressed concrete cylinder pipe of the pure spelter coating of 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 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; wherein the joint socket steel loop of prestressed concrete pipe directly exposes outside; there is not the protection of concrete layer; joint as two prestressed concrete pipes; the surface protection of the bellmouth steel loop of prestressed concrete pipe and the socket steel ring of prestressed concrete pipe is particularly important; the operational reliability of this direct threat tube system; thereby affect the safe operation of whole pipe-line system, so the bellmouth steel loop at the outer surface of Prestressed concrete cylinder pipe and two ends and socket steel ring process for treating surface are necessary extremely.
There is following shortcoming in present Prestressed concrete cylinder pipe technology:
Bellmouth steel loop and the socket steel ring surface at present domestic Prestressed concrete cylinder pipe two ends only are at the simple iron oxide red coating of external coating; antiseptic effect is undesirable; common iron oxide red coating can not effectively be protected bellmouth steel loop and the socket steel ring surface at Prestressed concrete cylinder pipe two ends when corrosive medium corrodes the bellmouth steel loop at Prestressed concrete cylinder pipe two ends and socket steel ring surface; and then can cause corrosive medium to corrode bellmouth steel loop and the socket steel ring surface at Prestressed concrete cylinder pipe two ends; the cover coat processing is not carried out on domestic Prestressed concrete cylinder pipe surface at present simultaneously; when corroding concrete surface, corrosive medium can not effectively protect steel cylinder and concrete outer surface; and then can cause corrosive medium to corrode steel cylinder and steel wire and cause corrosion failure, 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 bellmouth steel loop, socket steel ring surface and the concrete pipe outer surface that overcomes above-mentioned existing lined Prestressed concrete cylinder pipe two ends, a kind of joint socket and the pure spelter coating lined of steel cylinder surface band Prestressed concrete cylinder pipe are provided, this concrete pipe is simple in structure, corrosion-resistant, can effectively prolong working life of Prestressed concrete cylinder pipe.
For achieving the above object, the utility model adopts following technical proposals:
A kind of joint socket and the pure spelter coating lined of steel cylinder surface band Prestressed concrete cylinder pipe; 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 and steel cylinder outer wall cement mortar protective course from inside to outside; all be wound with reinforcement wire on the outer surface of steel cylinder and bellmouth steel loop, be respectively equipped with pure spelter coating on the outer surface of the internal surface of described socket steel ring, bellmouth steel loop and the steel cylinder outer surface.
Described pure spelter coating adopts electric arc spraying to make at finished product concrete pipe exposed bellmouth steel loop inwall and socket steel ring outer wall.
Pure spelter coating on the described steel cylinder outer surface adopts electric arc spraying before prestressed concrete pipe is made, and directly makes at the steel cylinder outer 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 Prestressed concrete cylinder pipe process for treating surface, especially cladding technique extremely is necessary.
The utlity model has following beneficial effect:
1, be that a kind of bellmouth steel loop, socket steel ring surface and steel cylinder outer surface are with the lined Prestressed concrete cylinder pipe of the pure spelter coating of thermal spraying at the utility model, the hot-spraying coating of steel cylinder adopts arc spray process before prestressed concrete pipe is made, directly make at the steel cylinder outer wall, the hot-spraying coating of bellmouth steel loop and socket steel ring adopts arc spray process to make at the exposed bellmouth steel loop of finished product concrete pipe and socket steel ring outer wall, increased together important barrier for the antiseptic property of lined Prestressed concrete cylinder pipe improves, it is convenient to use.
