“道碴桥面鋼筋混凝土梁預应力鋼筋混凝土梁直綫矩形桥墩”为第二設計院編制的标准图,图号“弍桥4040”。設計活載为中—22級。該图系配合“专桥1009”(lp=12~m,16~m,20~m),“专桥1002”(lp=24~m),“大138”(lp=23.8~m,27.7~m,31.7~m,中—26級)。适用于无水或少量流水的谷架桥。当基础建在基本岩层上,流速甚小、桥孔无压縮,将来亦不通航的河流上的桥墩也可釆用。 內容包括等跨配合七种,不等跨配合五种。各跨組合的墩身高度为:12+12,12+16:H=6～18~m;16+16:H=9～24~m;16+20,
Ballast deck reinforced concrete beam prestressed concrete beam straight rectangular piers “for the second design institute prepared standard diagram, drawing number” Baqiao 4040 “. Design live load for the -22 level. The figure is with the ”Bridge 1009“ (lp = 12 ~ m, 16 ~ m, 20 ~ m), ”Bridge 1002“ (lp = 24 ~ m), ”big 138" (lp = 23.8 ~ m, 27.7 ~ m, 31.7 ~ m, 中 -26 级). Suitable for dry or a small amount of water valley bridge. When the foundation is built on the basic rock formation, the flow velocity is very small, the bridge hole is uncompressed, and the piers on rivers that are not navigable in the future can also be used. The content includes seven kinds of cross-span coordination, ranging from cross-cooperation with five. The pier height of each cross combination is: 12 + 12,12 + 16: H = 6 ~ 18 ~ m; 16 + 16: H = 9 ~ 24 ~ m;
