At that time, participating units were railway corps, railway two bureaus, first, second, third and fourth designs Institute, Bridge Bureau, Fengtai plant, Southwest Institute, Iron Institute, professional design institutes. Under the correct leadership of the party committee of a division of railway corps and under the correct leadership of the party committee for railroad soldiers, the prestressed beam combat group has extensively mobilized the masses in accordance with Chairman Mao’s great teaching of “breaking the ocean and developing his own path of industrial development”, and successfully tested the ballastless ballast l_p = 23.8m tandem beam. (That is, transverse segmented beams) The advantages of tandem beams: (1) the purpose of pre-laying bridges can be achieved; (2) suitable for the needs of railway construction to fight the people’s war;
