一九六四年四月我院編制的公路桥涵工程設計图紙目录序号23,24,即盖板式方涵洞,淨跨1.0至3.0米,載電汽-10,汽-13,拖-60;近經检查,发現装配式盖板內的鋼筋数量基本上与整体盖板式相同,未按装配式盖板間无連接构造的分离板来重新配置鋼筋,因而使装配式盖板处于有較大超載的受力状态,为此,經研究确定将該两冊图紙中有关装配式部份停止使用。凡已接該图有关部份施工的单位,請对构造物进行一次检查;在老图尚未进行
In April 1964, the catalogs of road bridges and culverts in our hospital were numbered 23 and 24, ie covered square culverts with a net span of 1.0 to 3.0 meters and carrying electric steam of -10, steam -13 and tow -60 ; After inspection, it was found that the number of assembled cover plate is basically the same as the overall cover plate, without the connection between the assembled cover plate to reconfigure the reinforcing bar, so that the assembled cover is in Large overload state of force, to this end, determined by the study of the two volumes of the assembly-related parts to stop using. Those who have taken the construction of the relevant part of the map, please check the structure; in the old map has not yet been carried out
