Abstract
The utility model discloses an inner lining type prestress steel tube concrete pipe with an epoxy coal pitch anti-corrosion layer on the surface. The inner lining type prestress steel tube concrete pipe comprises an inner concrete layer, a steel tube and an outer cement motar protection layer in sequential arrangement from inside to outside, wherein a prestress steel wire is wound on the outer wall of the steel tube, and the epoxy coal pitch anti-corrosion layer is arranged outside the outer layer cement mortar protection layer. The inner lining type prestress steel tube concrete pipe has the advantages that the integral structure is very simple, the design is scientific and reasonable, good durability and anti-corrosion performance are realized, in addition, the manufacture process is simple, the service life of the inner lining type prestress steel tube concrete pipe subjected to the surface epoxy coal pitch anti-corrosion treatment is effectively prolonged, and the inner lining type prestress steel tube concrete pipe is novel.
Description
Technical field
The utility model belongs to the prestressed concrete member field, and there is the lined Prestressed concrete cylinder pipe of epoxy coal tar pitch coating on especially a kind of surface.
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.
There is following shortcoming in present Prestressed concrete cylinder pipe technology:
The cover coat processing is not carried out on domestic Prestressed concrete cylinder pipe surface at present; when corroding concrete surface, corrosive medium can not effectively protect steel cylinder; 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 overcoming above-mentioned existing lined Prestressed concrete cylinder pipe surface, a kind of lined Prestressed concrete cylinder pipe of simple in structure, the epoxide coal bituminous corrosion-inhibiting coating of surface band 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:
There is the lined Prestressed concrete cylinder pipe of epoxy coal tar pitch coating on a kind of surface; comprise the internal layer concrete layer, steel cylinder, the outer cement mortar protective course that set gradually from inside to outside; be wound with reinforcement wire on the steel cylinder outer wall, described outer cement mortar protective course outside is provided with epoxy coal tar pitch coating.
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 contained on the cement mortar protective course by epoxy coal tar pitch coating directly is coated with at the utility model, increased together important barrier for the antiseptic property of lined Prestressed concrete cylinder pipe improves, 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 process epoxide coal bituminous antiseptic lined Prestressed concrete cylinder pipe life-span of surface is effectively prolonged, and is the higher lined Prestressed concrete cylinder pipe of a kind of novelty.
Description of drawings
Fig. 1 is the utility model cross-sectional configuration schematic representation;
Fig. 2 is transverse cross-sectional view of the present utility model;
Wherein 1. internal layer concrete layers, 2. steel cylinder, 3. epoxy coal tar pitch coating, 4. reinforcement wire, 5. outer cement mortar protective course.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, 2; there is the lined Prestressed concrete cylinder pipe of epoxy coal tar pitch coating on the surface; comprise the internal layer concrete layer 1, steel cylinder 2, the outer cement mortar protective course 5 that set gradually from inside to outside; be wound with reinforcement wire 4 on the steel cylinder outer wall, described outer cement mortar protective course 5 outsides are provided with epoxy coal tar pitch coating 3.
Although above-mentionedly by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
