Abstract

The utility model discloses an embedded-type prestressing force steel cylinder concrete pipe coated with a fiber anti-crack layer and an anti-corrosion layer. The embedded-type prestressing force steel cylinder concrete pipe coated with the fiber anti-crack layer and the anti-corrosion layer comprises a cylinder body portion, a bell mouth steel ring and a socket steel ring which are arranged at two ends of the cylinder body portion. The cylinder body portion is sequentially provided from inside to outside with a steel cylinder inner wall concrete layer, a steel cylinder, a steel cylinder outer wall concrete layer, a steel cylinder outer wall fiber impervious anti-crack cement mortar protective layer and an outmost layer of an epoxy coal pitch anti-corrosion layer. Prestressed wires are winded around the outer wall of the steel cylinder outer wall concrete layer. The embedded-type prestressing force steel cylinder concrete pipe coated with the fiber anti-crack layer and the anti-corrosion layer is simple in structure, corrosionproof and capable of effectively prolonging service life of a prestressing force steel cylinder concrete pipe.

Description

There is the embed-type Prestressed concrete cylinder pipe of resistant fiber parting and anticorrosive coat on the surface
Technical field
The utility model relates to a kind of prestressed concrete member, and especially a kind of surface is with the embed-type Prestressed concrete cylinder pipe 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 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 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 outer mortar cover anti-permeation cracking-resistant of at present domestic Prestressed concrete cylinder pipe effect is undesirable; 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 that above-mentioned existing embed-type Prestressed concrete cylinder pipe surface anti-permeation cracking-resistant is processed and the technical deficiency of outermost surface protection in order to overcome; provide a kind of surface that the embed-type Prestressed concrete cylinder pipe of resistant fiber parting and anticorrosive coat 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:
There is the embed-type Prestressed concrete cylinder pipe of resistant fiber parting and anticorrosive coat on a kind of surface; 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 concrete layer, 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, is wound with reinforcement wire on the outer wall of steel cylinder outer wall concrete layer.
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.
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, surface of the present utility model is that the anti-permeation cracking-resistant performance of embed-type Prestressed concrete cylinder pipe improves with fibre crack-resistance screed and epoxy coal tar pitch coating, and the antiseptic property raising has increased dual barrier, the application convenience.
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; adopting the embed-type Prestressed concrete cylinder pipe life-span that the fibre anti-permeation cracking-resistant slush is processed and epoxy coal tar pitch coating is processed effectively to be prolonged through cement mortar protective course, is the higher embed-type Prestressed concrete cylinder pipe of a kind of novelty.
