装配式钢筋混凝土桥面桩柱基础桥,是农道桥梁中主要桥型之一。桥面为简支结构,对地基的适应性较强。同时,它具有结构简单、造价低、建设快、管理方便等优点,在三江平原农村建设中已被广泛采用。这种桥的桥面是由许多予制板块并列构成的,蜿蜒河配套工程农道桥跨径一般为6米,净宽为5米。中板宽多为1米,边板宽为0.75—1米。板块为实心,板厚28厘米,每块板都在4吨左右。组装时由于桥面板块自重较大,一般汽车式起重机吊不动,再加上三江平原许多地方低洼易涝,就是有相
Assembled reinforced concrete bridge pile foundation bridge, is one of the main bridge in the rural road. Deck for the simple structure, strong adaptability to the foundation. At the same time, it has the advantages of simple structure, low cost, fast construction, convenient management and so on. It has been widely adopted in rural construction of Sanjiang Plain. This kind of bridge deck is composed of many prefabricated plates juxtaposed, meandering river supporting farm bridge road span is generally 6 meters, net width of 5 meters. The width of the board is mostly 1 meter wide and 0.75-1 meter wide. Plate is solid, thickness 28 cm, each plate is about 4 tons.
