建凌桥是一座11孔的大型石拱桥,净跨24公尺,墩距27公尺,拱矢度6公尺。该桥于1957年10月开始施工,1958年国庆节正式通车使用。工程造价(包括基础、锥坡、梨埧、护坡、桥头路基):每延长公尺实际成本3,233元。在施工上,由于拱架支立每孔仅需10几名木工,用3～5天,所以比钢筋混凝土桥支架模型还要简单。拱圈砌筑每孔30～40名工人,一般需5～7天,相当于钢筋混凝土桥(?)钢筋、浇灌混凝土所需的时间。此外砌侧墙、铺桥面等工序亦不甚麻烦。拱桥砌筑冬季施工设备简单,可以克服季节影响。兹将几点施工经验介绍如下:
Jian Ling Bridge is an 11-hole large-scale stone arch bridge, net span of 24 meters, pier distance of 27 meters, arch degree of 6 meters. The bridge began construction in October 1957 and was officially opened to traffic on the 1958 National Day. Project cost (including foundation, slope slope, pear, slope protection, bridgehead subgrade): The actual cost per extension meter is RMB 3,233. In the construction, as the arches stand per hole only 10 a few carpentry, with 3 to 5 days, so it is easier than the reinforced concrete bridge bracket model. Arch ring masonry per hole 30 to 40 workers, usually take 5 to 7 days, the equivalent of reinforced concrete bridge (?) Reinforced concrete irrigation time required. In addition, side walls, pavement and other processes are not too troublesome. Arch bridge masonry winter construction equipment is simple, you can overcome the seasonal impact. Here are some construction experience is as follows:
