遵照伟大领袖毛主席“独立自主、自力更生”的教导,我们组成以工人为主体的三结合设计小组,创造性地把无碴无枕结合梁发展到19.6米的跨度。钢筋混凝土联合钢结构的结合梁以混凝土抗压,以钢材抗拉,从而充分发挥各该材料的优越性。而无碴无枕梁钢轨垫鈑经12mm厚硫化橡皮垫层直接安置在混凝土版上,又节约了大量的木材。本设计采用多主梁低高度型式,结合梁建筑高度:轨底至梁底为1478mm,分別较同跨度标准钢梁(大-058)和钢筋混凝土梁(专桥-1002)低33％和43％。由于梁体高度小,提高了通航净高,这对江南水网化流域具有很大的
Following the guidance of Chairman Mao, the great leader, “independent and self-reliance,” we formed a three-in-one design team with a worker as the main body to creatively expand the ballastless pillow to a span of 19.6 meters. The combined beams of reinforced concrete and steel structure are compressive with concrete and tensile with steel to give full play to the superiority of each material. The ballastless pillowless rail mat sheet by 12mm thick vulcanized rubber cushion placed directly on the concrete version, but also save a lot of wood. This design uses the low height multi-girder type, combined with the construction height of the girder: the rail base to the bottom of the girder is 1478mm, respectively 33% and 43% lower than the same span steel beam (-058) and the reinforced concrete beam %. Owing to the low beam height, the navigation net height is increased, which has a great
