随着社会主义农业生产的发展,就需要修建适应农业运输的各种农村道路和桥涵。特别是自1958年后,我国农村大搞水利,农村渠道密网如织,河沟增多。由于渠道的开辟,桥涵配套工作未能跟上,而使许多公路、生产道、人行道被截断,因此农村交通运输极感不便。根据调查,有些地区缺乏桥涵,往往因一河之隔,使社员下田劳动要涉水过河或绕远道而行;拖拉机、手推车等农业运输工具也因此而得不到充分使用。有些地区因为农业机械的推广和使用,荷载的增大,原有的一些桥涵(特别是木桥)承受不住。因此修建农村桥涵就显得日益迫切。对农业运输,发展生产,保证人畜安全,活跃城乡经济就具有更重要意
With the development of socialist agricultural production, various rural roads and bridges and culverts adapted to agricultural transport need to be constructed. Especially since 1958, China’s rural areas engage in water conservancy, rural areas such as dense network of channels, increased river ditch. Due to the opening up of the channels, the supporting work of bridges and culverts failed to keep up with many of the roads, production roads and sidewalks being cut off, making rural transport extremely inconvenient. According to the survey, bridges and culverts are lacking in some areas, often resulting from cross-river interdictions. Members of the public are forced to go to work on the fields to cross the river or to travel far and wide. Agricultural tractors such as tractors and trolleys are not fully used. In some areas, due to the popularization and use of agricultural machinery and the increase of load, some existing bridges and culverts (especially the wooden bridge) can not stand. Therefore, building bridges and culverts in rural areas is increasingly urgent. It is even more important for agriculture to transport, develop production, ensure the safety of both domestic and livestock, and activate the economy of urban and rural areas
