河北省衡水县王许庄村南京开公路上修建4孔5米砖拱桥时,因缺乏拱架材料,采用了砖木土坯拱架。不仅克服了材料不足的困难,而且大大降低了工程造价,同时施工方法简易。今将砌筑方法介绍如下:砖木土坯拱架主要是利用桥梁本身所备的砖料做拱架的支撑墙,用较短小的木料做横梁和拱圈木,用荆巴、苇席等加草泥抹顶而成。砖砌支撑墙的间距,看横梁和拱圈木的规格而定,一般以2至3米为宜(因这样的木料当地最容易解决)。拱圈木之间距,视荆巴、苇席等材料的强度而定,采用密排或留有一定的间隙。本工程是采用荆巴,其间隙采用中到中为20~25厘米。拱架的结构如图。
Wang Xuzhuang Village, Hengshui County, Hebei Province, Nanjing Road to open a 4-hole 5-meter brick arch bridge, due to the lack of arch material, the use of brick and wood adobe arch. Not only overcome the lack of material difficulties, but also greatly reduce the project cost, while the construction method is simple. The masonry method will be introduced as follows: Brick and concrete adobe frame is mainly used to make the bridge itself supporting brick arch wall, with shorter and smaller wood beams and arch arch wood, with Jingba, reed seats plus Mud top from the mud. The spacing of the brick support wall, depending on the specifications of the beams and arch ring wood, usually 2 to 3 meters (due to such wood local most easily solved). The distance between arch circle wood, depending on the strength of Jingba, reed mat and other materials may be, using close or leave some gaps. This project is to use Jingba, the gap to use in the 20 to 25 cm. The structure of the arch frame.
