Study Of The Contriving Method Of The Prestress Concrete Hollow Plank

Prestressed Concrete Bridge(PC) is extensive now.According to the abroad,the blemish rate of PC is lowest in each kind of bridge,and the durability of PC is the best. Ever since the end of 20 centuries,the evolvement of PC have taken on a new look overseas that the span has been broken continually,and the durability of has been increased,the prefabricated and constructional structure has been applied in quantity.In a word,These were dependeed on the applications of HPC and the stainless material and reinforcing steel bar.It is the local development circumstance that The bridge construction speeds obviously,the high-quality material gets expansion, the bridge standard norm revises continuously, these varieties push new theories of the bridge construction realm,new technique,new the method flow out now.For the moment,it is the interior circumstance of it that the Prestressed Concrete Hollow Slab Bridge has been applied in great quantities such as Highway and urban road.The characteristic of the Prestressed Concrete Hollow Slab Bridge is a simple structure.It can be made in factory.It is very easy to cantorl the quality and reduce the cost.If you need,you can use reinforced concrete(RC) or PC,and you can use a hollow one or solid one,or make a curve-bridge,slope- bridge,or a catercorner-bridge by useing it.Becourse of the limited of height,the Hollow Slab Bridge usually was used,and,it reduced the consume of soil and the engineering work load.So it is more popular now in normal or advanced highway and urban road.Because the slab bridge has the point of simple structure,specific endure, can prefabricate by factory, easy to controlling the quality and decline the cost. It also could adopt reinforced concrete or...
