河北省保(定)沧(县)线路面工程,原计划采运房山县天然砾石来铺装级配路面,后因石料运距过远,每公里路面造价至少需6万余元,太不合算。于是准备把河间一段长约30公里的路面,改用碎砖铺作底层。但又苦于缺乏砖料,之后,沧县专区筑路指挥部采纳了一位转业军人的建议,用“无窑烧砖法”试烧砖料成功,可以就地大量烧制。笔者曾到试烧“无窑烧砖法”的工地访问,据告:这种方法系湖南、福建等省民间的简易烧砖法,凡有粘土的地区都可就地烧制。每次能烧6,000—150,000块。此次试烧结果,每砖成本约合0.016元,如一次烧制块数越多,成本越低。烧制时间,从砌筑砖坯起到烧成止,共历12日。烧制时需要的人力不多,尤其在闷烧期间,只须一、二人在窑边照料即可。
Hebei Province (Catchment) Cang (County) line pavement project, the original plan to pick and collect natural gravel from Fangshan County to pavement grading pavement, after the stone away too far, the cost per kilometer road at least 6 million yuan, too Cost-effective. He was ready to put a section of Hejian about 30 km of pavement, replaced with broken brick shop for the bottom. However, lack of brick material, but later, Cangxian District Road Construction Headquarters adopted a proposal of military diversion, with “no kiln burning brick” test brick burning success, you can place a lot of firing. I had to try to burn “no kiln burning brick” site visit, it was reported: This method is the Hunan, Fujian and other provinces of simple folk Burning brick method, where the clay can be locally fired. Each can burn 6,000-150,000 pieces. The test results, the cost per brick about 0.016 yuan, such as a burning block the more the lower the cost. Burning time, starting from the brick masonry firing only a total of 12 calendar. When firing small manpower needed, especially in the smoldering period, only one or two people in the kiln can take care of.
