Description
Technical field：
The present invention relates to a kind of drainage pipeline being provided with fiberglass enhancement layer and preparation method thereof.
Background technology：
The forties in 20th century, French Bang Na pipeline company designs first and has manufactured pre-stress steel cylinder cement mortar pipe
(PCCP).America and Europe competitively develops PCCP, and the U.S. is to produce and use the most country of PCCP, and so far, the U.S. uses
PCCP28000km, maximum caliber reaches 7600mm.Nearly ten years, PCCP pipe, in Chinese fast development, counts report according to employer's organization
Accuse, 2010, Chinese yearly productive capacity broke through 3000km, year output reaches 1500km, and (U.S.'s peak annual output is 1971
Year, it is 3563327 feet, about 1100km), accumulative usage amount has reached 8000 kilometers.China has been PCCP production and application now
Amount highest country.Ministries and commissions of National Development and Reform Committee, Ministry of Water Resources, Ministry of Construction etc. seven, combine " the Chinese water-saving technology political affairs of issue for 2005
Plan outline " is expressed, and the waterline of more than DN1200 bore preferentially adopts PCCP.Since introducing this technology, public opinion is generally recognized
For：PCCP is steel pipe and cement mortar manometer tube advantageous combination, economical and anti-corrosion.Chinese PCCP expert is in recent years in a lot of pieces
The PCCP life-span is claimed up to 100 years in article.Because its low cost is economical and practical, and because load is high, bearing capacity is strong, anti-brush up against anti-
The special performance digging in water supply and sewage field market share at most, existing more than 70 year history so far, the huge legendary turtle of exclusive drainage pipeline
Head.
But, in actual motion, PCCP does not reach expected using effect.Last century the nineties are Libyan
" the big race in Africa " engineering adopts the PCCP of 4000mm bore, and operating pressure is 2.8Mpa, and overall length 3300km (two-wire), by U.S.
State and Cooperation in Korea are built；This huge engineering, is the outstanding the strongest case of PCCP Technological Economy in the world.This engineering in
Start within 1984, complete within 1996, be the large-engineering being known as world's miracle.But when calendar year 2001 was by 2005, this " runs good
Well " engineering has occurred and that 5 explosions；To part pipeline (about 1000km) through detection, have been found that steel wire fracture within 2011
35000, it is badly in need of formulating positive rehabilitation plan.This engineering now, thousands of section pipeline sections need repairing or change, remaining pipe
Road needs to carry out state estimation.The first stage project from 1991 completes and runs to calendar year 2001 explosion to occur, only 10 years；Arrive
Thousands of section pipeline sections need repairing or change within 2011, only maintain 20 years, its service life well below service life 50 years, its
The actual average life-span only has 11.7.
Chinese PCCP also when have explosion event, but these events do not cause the attention of user, developer and designing unit；
Relevant responsible department is also not given to due care to this.For example, water utilities company in Ningxia employed tens kilometers before 8 years
The PCCP of DN800, has occurred that multiple explosion, steel wire fracture in 50 many places after testing, occurs explosion to cut off the water thing
Therefore probability significantly rise, had a strong impact on the safe operation of this water utilities company.
As can be seen here, at present, the explosion damage problem of PCCP is very prominent in the whole world, and the U.S. is the elder generation of PCCP pipe
Passerby, tap water association of U.S. WARF (AwwaRF) issued " PCCP inefficacy " specialist paper in 2008, and " wished
This result will be applied to All Around The World ".With the calamity of the very high failure likelihood of PCCP and inefficacy, lead to the U.S. existing
In not reproduction PCCP.Stop production closing to the A Meilong company of Chinese export technique, Price brother company.The U.S.
The water utilities mechanism PCCP in the own system of dialogue, take blood pressure lowering, examination ＆ verification to run, inside and outside checks and repairs or change pipeline
Deng action.
Trace it to its cause, really PCCP has economy and corrosion-resistant characteristic, its core means is using high-tensile steel wires and pre-
Stress technique.The design stress of steel wire is more than 5 times of steel pipe steel, has thus saved steel and has obtained economy；Cement bonded sand
Slurry and mortar wrapped wire and steel cylinder, thus achieve corrosion-resistant.These are the expectations of developer when developing this product,
It is the performance that this product put into operation in a period of time；But elapse over time, the practical manifestation of PCCP is same to be expected to have very
Big difference, the original advantage of corrosion-resistant aspect is simultaneously not so good as design ideal.PCCP dominant failure mode is that steel wire corrosion pipe is quick-fried
Splitting. the anti-layer of cement mortar itself of protection steel wire is fragile, and in operation, it cannot be protected, and its life-span becomes determining of PCCP life-span
Determine factor. heavy caliber PCCP pipeline " swell increment " of high internal pressure is big, special hazard.As can be seen here, in water delivery engineering in the urgent need to
A kind of drainage pipeline that can run steadily in the long term.
