A novel asynchronous-pouring-construction technology for prestressed concrete box girder bridges with corrugated steel webs
'Elsevier BV', 2020Co-Authors: He Jun, Li Xiang, Li Chuanxi, Correia, José A.f.o., Xin H., Zhou ManAbstract:Owing to the superior mechanical performance and material efficiency, the combination of prestressed concrete (PC) slabs and corrugated steel webs (CSW) as PC girder with CSWs (PCGCSW) is extensively applied to railway and highway bridges. To overcome the shortcomings of traditional balanced cantilever construction (TBCC) of PCGCSW, reduce environmental impact, and promote sustainable construction, a novel asynchronous-pouring-construction (APC) technology is introduced in this paper. This improved method makes full use of the excellent shear capacity of the corrugated steel webs (CSWs) to support the Hanging Basket, increases the construction platforms to accelerate the construction speed. Based on a practical project of a long-span composite box girder bridge with CSWs in China, the construction process of the APC method is systematically introduced, and the structural safety and environmental sustainability of such bridge using APC technology are evaluated and compared with that using TBCC. The comparison results indicate that APC method can reduce the compressive stress of top concrete slab, but slightly increase the shear stress and deflection during the cantilever construction stage because the Hanging Basket is directly supported by CSWs. Besides, the weight of the improved handing Basket in APC technology is reduced up to half in comparison that in TBCC. Accordingly, the APC technology saves a lot of energy consumption, reduces huge CO2 emissions for construction equipment, and shorts construction period. Therefore, the utilization of APRC technology can ensure the bridge's safety and reliability, effectively accelerate construction speed, reduce the construction load, decrease the environmental pollution, and save the engineering cost, which can be regarded as a sustainable and environmental-friendly construction method for composite bridges with CSWs.Steel & Composite Structure

novel fire balloon Hanging Basket and manufacturing method thereof
2015Co-Authors: Yu GuangqianAbstract:The invention discloses a material formula of a fire balloon Hanging Basket, in particular to a novel fire balloon Hanging Basket and a manufacturing method of the novel fire balloon Hanging Basket. According to the technical scheme, the materials formula mainly comprises, by weight, 20% - 30% reinforced nylon film, 30% - 40% environmental friendly plastic, 15% - 20% obstructing anti-explosion material, and 5% - 10% RC-001 inorganic nanometer fire-proof insulating layer. The novel fire balloon Hanging Basket has the advantages that the heat insulating property is good, the load is big, and the Basket can float on water, particularly, due to the fact that the reinforced nylon film is filled with the environmental friendly plastic, the weight is light, and the Basket can float on the water. The drowning phenomenon caused by falling accident of a fire balloon can be prevented, and the Basket can float on the water. By using the obstructing anti-explosion material as an inner material, the anti-explosion effect can be achieved. By arranging the nanometer fire-proof insulating layer on the outermost layer, the fire-proof function can be achieved, and the heat insulating effect can be achieved, so that passengers are free from the influence of low-temperature environment in a high altitude.
