| Bridge deck pavement is the key technology areas of the bridge projects, since the 1990s, China set off a wave of long-span bridge construction boom, and among these new long-span bridges, the vast majority are used orthotropic steel panels, which further accelerates the steel deck pavement research process, also contributed to the development of our country’s steel deck pavement career.For the current status of a large number of steel widely used,to form a relatively complete sets of steel bridge deck completed application technology has become an urgent issue in the country.Germany is the earliest country in the world to start research and practice in Steel Deck Pavement. France, Japan, the United States and other countries have also carried out work in this area later.Germany and Japan have also developed a corresponding technical specifications. These countries for steel bridge deck pavement design (including the pavement materials and thickness design) mainly use combined materials testing experience design.Throughout the case of long-span bridges’steel bridge deck in every country, all kinds of paving materials have different levels of application, some advocate the use of a thick layer of pavement, some advocate a thin layer of pavement, and the use of effects is also different.In this paper, to the construction of the bridge Qingdao Bridge test, based on the rational use of equipment and construction technology test, pouring asphalt concrete bridge deck technology in depth. Qingdao Jiaozhou Bay Bridge spans, the Qingdao, east and west connecting two major urban areas. East of the main city of 308 State Road, across the Jiaozhou Bay, west of Huangdao red cliffs, the route is about 35.4 km, of which 26.75 km length of the sea.5.85 km land bridge Qingdao side. Hongshiya side onshore section of the bridge and a total of 0.9 kilometers of road, Red Island cable length 1.9 kilometers, the total investment of 9.938 billion yuan.By contrast research, Jiaozhou Bay Expressway (Qingdao to Huangdao direction) women regardless of port Bridge and the Bay Bridge in the environment, and other aspects of traffic and load closer, as the representative of the bridge deck pavement test, the headquarters of Qingdao executives at the city consultation, select the bridge (test interception length 600m, width 5.5m, thickness 9cm). Experimental research entities.Through practical problems encountered during construction, after careful analysis and research, for the construction of the actual circumstances of the specific construction plans and construction measures. On the basis of seeking truth from facts, scientific and reasonable, advanced process technology is feasible and affordable principle, combined with practical engineering related to quality, schedule, safety, environmental and other requirements for the preparation of construction plans. Implementation of the project construction management method by optimizing the disposal of technology, programs, services, equipment, materials, capital, information, time and space conditions, to achieve the desired objectives effect duration, cost, quality and social credibility. Adhere to the principles of construction of specialized organizations, arrange professional team has extensive experience in the construction of the bear.Study on the construction of this bridge project Qingdao Bay Bridge test of pouring asphalt concrete bridge deck structure and construction of process parameters on the basis of great significance. In the future, pouring asphalt concrete bridge deck construction which, we learn from the advanced experience in construction and abroad, combined with the actual situation in the theory of knowledge and the construction of each specific project, optimize the construction program, choreography reasonable construction organization plan, strict implementation; while strengthening quality control, so that the true theoretical knowledge combined with engineering practice, to play its proper function. |
