Abstract
The invention provides a PCCP (prestressed concrete cylinder pipe) with an epoxy resin cement protection layer and a production method. The PCCP is characterized in that a layer of epoxy resin coats the PCCP with the epoxy resin cement protection layer, and one flat, compact and smooth epoxy resin cement protection layer also coats the surface of the epoxy resin. The PCCP and the production method provided by the invention have the beneficial effects that the production and processing methods are simple and convenient, and the produced PCCP with the epoxy resin cement protection layer has the advantages of large caliber, high-temperature resistance, high-pressure resistance, impact resistance, corrosion resistance, long service life and smooth appearance, and is suitable for large-scale water supply pipeline engineering adopting ground pavement, high-altitude erection, sea bed pavement and saline-alkali region ground burying.
Description
Affiliated technical field
The present invention relates to a kind of heavy caliber pressure of supply water pipe, the especially a kind of Prestressed concrete cylinder pipe with epoxy mortar protective layer and production method that applies epoxy mortar at the outer cement protective layer of PCCP pipeline.
Technical background
The production technology of existing PCCP aqueduct external protection is, by twining after pipeline after silk sprays mortar, is finished product.The mortar that this speed with 37 meters per second sprays; although there is stronger adhesion; but the grains of sand adhere to and pipe bucket outer wall in the mode of mutual crash situation when injection at a high speed; make outer mortar cover inevitably form the fine capillary channel mutually connecting; these fine capillary channels have certain water permeability; make the steel cylinder outer wall of pipeline and the steel wire of steel cylinder outer wall winding very easily be subject to the corrosion of external environment condition and damage, cause the generation of the accidents such as booster.
For example: in the PCCP pipework of the cooling circulating water of large power plant, because conduit running is under high temperature, high pressure conditions, and the outside of pipeline is usually under high temperature, high humidity environment, and existing PCCP pipeline is very easily subject to the corrosion and damage of environment, leads to large accident.
Therefore, people wish the novel PCCP prestressing force power plant cooling water cylinder concrete pipe that a kind of heavy caliber, high temperature resistant, high pressure resistant and external protection have again anti-corrosion function.
Summary of the invention
In order to meet the above-mentioned demand of people, the invention provides a kind of Prestressed concrete cylinder pipe with epoxy mortar protective layer and production method that applies epoxy mortar at the outer cement protective layer of existing PCCP pipeline.
The present invention solves the technological scheme that its technical problem takes:
Prestressed concrete cylinder pipe and production method with epoxy mortar protective layer; it is characterized in that: its Prestressed concrete cylinder pipe with epoxy mortar protective layer is coated with one deck epoxy resin, on the surface of epoxy resin, be coated with again the smooth closely knit smooth epoxy mortar protective layer of one deck.
The invention has the beneficial effects as follows: the Prestressed concrete cylinder pipe with epoxy mortar protective layer of the present invention and production method; there is production and processing method easy; the Prestressed concrete cylinder pipe with epoxy mortar protective layer of producing has advantages of that bore is large, high temperature resistant, high pressure resistant, shock-resistant, corrosion-resistant, the life-span is long and outward appearance is bright and clean, is applicable to that ground is laid, set up in high-altitude, the buried large-scale water supply line engineering of laying down on sea bottom and varieties in saline-alkali areas.
Embodiment
Prestressed concrete cylinder pipe and production method with epoxy mortar protective layer; its production method is: in the last operation of whitewashing together of traditional PCCP pipe production; adopt scraping device that the slush surface after whitewashing is struck off; simultaneously, the device of the coating epoxy resin of follow-up is coated with epoxy resin and strikes off rear crude pipe surface, then after the epoxy mortar applicator that follows up epoxy mortar is applied with epoxy resin surface and pressurizes floating simultaneously.
With Prestressed concrete cylinder pipe and the production method of epoxy mortar protective layer, in its pipe production, whitewash; Scraping device strikes off the slush surface after whitewashing; Applying Epoxy Resin Unit applies epoxy resin and strikes off rear crude pipe surface; Epoxy mortar applicator applies epoxy mortar and pressurizes floatingly simultaneously, whitewashes, strikes off, is coated with epoxy resin, coating epoxy daub pressurization is floating for synchronously carrying out.The Prestressed concrete cylinder pipe with epoxy mortar protective layer that this method is produced; smooth surface; top layer protective layer degree of compaction is high, high temperature resistant, high pressure resistant; outer epoxy mortar protective layer does not have the capillary channel of infiltration; there is very strong water proofing property; can effectively protect steel cylinder tube core and reinforcement wire not to be subject to external corrosion environmental corrosion, extend the working life of pipeline, avoid being occurred because pipeline corrodes the accident causing.
Claims (2)
1. with Prestressed concrete cylinder pipe and the production method of epoxy mortar protective layer; it is characterized in that: its Prestressed concrete cylinder pipe with epoxy mortar protective layer is coated with one deck epoxy resin, on the surface of epoxy resin, be coated with again the smooth closely knit smooth epoxy mortar protective layer of one deck.
2. the Prestressed concrete cylinder pipe with epoxy mortar protective layer as claimed in claim 1 and production method; its production method feature is: in the last operation of whitewashing together of traditional PCCP pipe production; adopt scraping device that the slush surface after whitewashing is struck off; simultaneously, the device of the coating epoxy resin of follow-up is coated with epoxy resin and strikes off rear crude pipe surface, then after the epoxy mortar applicator that follows up epoxy mortar is applied with epoxy resin surface and pressurizes floating simultaneously.
