一、设计内容钢筋混凝土装配式桥面,根据省交通厅设计图纸,跨径分6、7、8、9、10公尺五种,载重汽—8,以拖—30验算,桥面净宽6公尺,适应双车道要求,用5根丁梁,每梁的桥坂宽度为1,3公尺,相邻两丁梁在桥面部位和横隔版部位用连系钢钣焊接,使5根丁梁连成一体,混凝土采用170级。桥面铺装2公分厚水泥沙浆,1公分防水层,4公分厚混凝土保护层,最上有3公分厚沥青混凝土面层。苏州段的装配式桥面,首先在沪宜公路潘墅港桥进行,该桥原系5.4—10—5.4公尺钢筋混凝土椿墩台木面桥,两座桥墩在抗战时被破坏,在此次改进中进行修复,中孔做装配式丁梁,两边孔浇筑肋版式桥面。
First, the design content Assembled reinforced concrete deck, according to the provincial Department of Communications design drawings, span 6,7,8,9,10 meters five, truck-8 to drag -30 count, the deck net Width of 6 meters, to meet the requirements of two-lane, with five Ding Liang, bridge beam width of 1,3 meters, the adjacent two Ding Liang parts of the deck and the diaphragm with the connection sheet metal welding, So that five Ding Liang into one, using 170 concrete grade. Deck pavement 2 cm thick cement mortar, 1 cm waterproof layer, 4 cm thick concrete cover, the top 3 cm thick asphalt concrete surface. The prefabricated bridge deck in Suzhou section was first carried out at Pan-Shui Port Bridge of Shanghai-Yixing Highway. The bridge originally consisted of 5.4-10-5.4 meters reinforced concrete pounding piers, and the two piers were destroyed during the war. Times to improve the repair, the hole to do assembly Ding Liang, both sides of the hole pouring ribbed deck.
