Use high across the sea of the function of PC steel long, sea bridge ~ ~, Vietnam g Finn bridge

Support the Vietnam economic sea bridge high anticorrosive requirements and shorten the construction period
Vietnam in the rise of emerging Asia, is one of the country each year to maintain high GDP growth rate.In recent years, it has a lot of foreign enterprises to Hanoi, the capital of north, in the economic development of the background, the use of Japanese JICA (independent administrative legal international cooperation agency) is the capital of construction of coastal city, regional international big port of the depth of the water, as part of its traffic roads and construction is ", Mr Bridge ".We had an interview with local construction engineering company and is responsible for the construction of sumitomo mitsui construction (strains) of a beau's west village.
", Mr Bridge is the longest bridge interval more than 5.4 km, Vietnam sea bridge.Because is located in the sea, therefore requires a PC steel with high anti-corrosion performance.To meet the demand, is sumitomo electric corrosion resistance of PC steel products.Because the double cladding has corrosion resistance and firmly, don't need at the scene of the homework for mortar (anti-rust materials such as cement paste and resin) injection operation and PE pipe connection operation, it is a great way to shorten the construction period and ShengLiHua"
However, the actual transportation to the site, to feed, there is a huge topic.
The scene of the cable processing problem
The steadfast and unyielding efforts bring success
Usually steel makers in Japan, steel cut into the specified length in the factory, and then more PC bundled into a steel cables again after delivery of the goods.But to transport to Vietnam by this method, low cost performance obviously.After repeatedly to discuss, decided to cut off before the product transportation to the scene, cutting and processing at the scene.Was sent to Vietnam, is responsible for the guidance of personnel at the scene early is sumitomo electric nongovernmental department.
"Issue is that from processing to girder inserted in the process, must not damage by PE coating epoxy resin coated the surface of the PC steel products.Field processing is the 1 cable winding on the wooden drum, with 60 m cut off for the unit, then 19 root bound together.But Vietnam not will be the operator of the PE coating corrosion resistance of PC steel bundling insert again experience in advance.In order to avoid the Angle of concrete and steel material damage, such as job must be careful careful, in order to make homework personnel understanding and recognition of this, we have patiently guidance.In addition, by ensuring that 60 m length of the necessary instruments and equipment development efforts, finally achieved in the field of cable processing, and insert operations"
People are so steadfast effort to promote the economic artery of the birth of new Vietnam.
PC technology's future comes from Japan high function of PC steel products to the world
The PC technology, not only the bridge.It is also suitable for large scale LNG tank, fluctuation process tank, line concrete sleeper and anchor block, etc.In addition it can also realize no column large space building, in addition to the gym and the hall and other buildings, also recently used in wind power rotation.
Blanket of sumitomo electric PC business reality yamada said.
"For the past to build social infrastructure, using the latest technology, under the conditions of more robust implementation of long, this is our social mission.To this end, we actively promote laws of PC steel high function and high additional value, in the surrounding technology package, provide holistic solutions at the same time, we hope to promote further the purpose of development"
At the same time focus on the business in overseas promotion
"Developed countries growing old infrastructure, demand for the development of emerging countries are rising.So, now we have 3 in the United States, 1 manufacturing locations in Indonesia, is pushing the global PC business.Our PC steel products in high demand functions that are of long life of infrastructure at the same time, also considering the sumitomo electric PC based technology development ability of lead the world to produce high strength and high corrosion resistance of PC steel products and optical testing, etc., promoted to the international standard"
PC steel products are derived from Japan to the world.Sumitomo electric坚信，这样的努力将对世界各地的基础设施建设作出贡献，进而让世界各地的人们过上更加丰饶的生活。
