After nine years of construction, the whole length of fifty five kilometers, set bridges, islands, tunnels in one amongst the Hong Kong-Zhuhai-Macao Bridge, was formally opened on United Nations Day, 2018 operation. Huizhong Zhi, gathering power, tens of thousands of builders unconquerable, uninterrupted struggle, with heart and sweat poured into the “Great Wall of the sea” across the 3 places.
The world’s longest cross-sea bridge thus far has been named “one of the Seven Wonders of the New World” by the Guardian. Behind the “Super Project”, Nature is driven by the facility of materials and technology! it’s a awfully sizable amount of scientific and technological innovation, new materials, technology, new instrumentality, technology in AN endless stream, solely the amount of patents up to 400! Let’s explore a number of these composite applications.
New compound Plastic model
In the construction of artificial island spring ditch, the new compound plastic model developed by Canton Road billion road Engineering Co., Ltd. has contend a substantial role. it’s according that the plastic model is created of thermoplastic long fiber strengthened compound composites, a area unit of plastic mould weight of concerning 10kg, solely seventh of the steel mould, however additionally has wear resistance, anti-corrosion, high strength characteristics.
Plastic model employing a unified combination of elements, will be versatile and speedy model assembly, construction personnel solely want straightforward coaching will quickly master the operation, whereas the development of the model there’s no residual nail, spikes and alternative problems, will greatly cut back the development safety risks.
Seismic isolation technology of OVM Bridge
With the grouping technology of formed bearing platform and Pier body section, the Anchorage technology of OVM prestressed giant diameter high strength rebar is that the key technology of section grouping application. That is, the bridge beam body is split into many segments, within the works prefab when transport to the bridge position for the Assembly, through the applying of prestress are the section as an entire into a bridge construction technology. OVM Bridge Isolation Technology, is that the bridge construction and also the lower structure or foundation between the installation of isolation device, ordinarily wont to cut back the unstable support, dampers, etc., so as to extend the first structure system cycle and/or damping, cut back the structure of the unstable response or cut back the energy input to the construction, to attain the expected unstable fortification needs.
At the start of the planning, the Hong Kong-Zhuhai-Macao Bridge, in line with the special operational conditions, needed the bridge to resist hurricane level sixteen or on top of, that is that the most exigent domestic bridge project within the current fight against the wind. when several debugging, finally determined to use China Ovim Company’s wholly-owned subsidiary-Liuzhou Oriental Engineering Rubber merchandise Co., Ltd. freelance analysis and Development, production of lead isolation rubber support and high damping isolation rubber bearing 2 varieties of support.
Ultra high mass synthetic resin fiber
The superior rope that upraised the Hong Kong-Zhuhai-Macao Bridge was made of Sinopec urban center Chemical analysis Institute Co., Ltd. and also the China Textile analysis Institute, that took quite quite ten years to develop and with success developed super compound synthetic resin fiber. within the 2006, this technology was transferred to Yizheng chemical fiber for plant construction. This ultra-high mass synthetic resin fiber, the thickness of solely 1/10 of the hair, however manufactured from cable, than the strength of the cable is higher, the gravity will reach thirty five weight unit. immoderate high mass synthetic resin fiber, the merchandise is named “Force fiber”. With carbon fiber, aramid and referred to as the 3 superior fibers, is presently the world’s highest sturdy quality fiber, within the national defense military and civil trade have a good vary of applications, is that the powerful sturdy army of strategic product. The sling utilized in the Hong Kong-Zhuhai-Macao Bridge consists of 100 thousand of such threads.
Adhesive for upper deck Paving
HONG KONG-Zhuhai-Macao Bridge bridge body last twelve meters Heilong project and upper deck pavement solutions, by Hubei Hui New Materials Co., Ltd. Holding enterprises Shanghai Hui New Materials Co., Ltd. to supply R & amp; d support and products services. Aiming at the technical characteristics of epoxy glue waterproofing layer of Hong Kong-Zhuhai-Macao Bridge and also the demand of high index, the corporate has with success solved the tough issues of bridge bonding materials and construction technology beneath advanced setting through physical and chemical review and check construction tests on the Hong Kong-Zhuhai-Macao Bridge. when the location performance testing to get the Hong Kong-Zhuhai-Macao Bridge Project Department consultants extremely recognized, within the competition with variety of international adhesive giants and quite twenty foreign brands stand out, exclusive bid.
120 years behind service life: anticorrosive coating
The design lifetime of the Hong Kong-Zhuhai-Macao Bridge has broken the same old “century-old practice” in China, setting style standards for a hundred and twenty years. so as to attain this goal, a spread of special style suggests that and anti-corrosion coating system is employed. for instance, the Jiuzhou Waterway bridge adopts the consolidation constraint system of Tower beam pier from 2 aspects of landscape and maintenance. This eliminates the massive unstable support, horizontal wind support and damping devices at the bridge tower and also the maintenance of those devices, whereas reducing the dimensions of the beam finish telescopic device and providing convenience for maintenance work. The anticorrosive coating system of the Hong Kong-Zhuhai-Macao Bridge, that refers to several giant bridges reception and abroad, and also the new coating and cathodic protection combined protection technology developed severally by the Institute of Metals of the Chinese Academy of Sciences, has contend a vital role during this project.
