增产节约是我国进行社会主义建设的基本方法。今年是我国进行第一个五年计划的最后一年,全国人民正在大力进行增产节约,公路系统也不例外。今年由于国家全面安排,对公路建设投资有些缩减,加以当前原材料的供应也很紧张,在这种情况下,更须切实地、积极地厉行增产节约,才能使公路运输工作适应国民经济发展的要求。那么,我们应从那些方面来进行增产节约呢? 第一、公路设计是否合理是能否节省国家投资、节约材料和降低成本的重要关键。因此,在国家投资相对减少和材料供应紧张的情况下,贯彻“分期修建”和“就地取材”的原则,就具有特别重大的意义。如在产砖石的地区,就应尽量用砖石做墩台、拱涵、石拱桥和石盖板涵等;产木材地区,尽可能多做木桥。一船路面,除规定者外,应视当地所产材料种类,设计不同的路面。在低窪的道路上,根据具体情况,可采用过水路面、过水桥,并应尽可能利用原有构造物。至于安全系 Increasing production and saving is the basic method for our country to carry out socialist construction. This year marks the final year of our country’s first five-year plan. People across the country are making great efforts to increase production and save energy. The road system is no exception. This year, due to the comprehensive arrangement of the state, investment in highway construction is somewhat reduced and the current supply of raw materials is also very tense. Under such circumstances, more efficient and economical production must be earnestly and vigorously implemented in order to adapt the road transport work to the requirements of national economic development . So, should we increase production and saving from those aspects? First, the reasonableness of road design is an important key to saving the country from investing, saving materials and reducing costs. Therefore, with the relative reduction of state investment and the tight supply of materials, implementing the principle of “building by phases” and “drawing on the spot” has great significance. As in the masonry area, we should try to make brick pier, arch culvert, stone arch bridge and stone cover culvert, etc .; production of timber areas, as much as possible wooden bridge. A boat pavement, in addition to the provisions of, should be depending on the type of material produced locally, the design of different pavement. In the low-lying roads, depending on the specific circumstances, the over-water pavement and over-water bridge may be used, and the original structure should be used as much as possible.
