为了在建筑上节约金属材料和降低工程造价,近几年来,不少的研究、设计和施工单位已积极地进行了在水道工程方面以陶土管、陶瓷管代替金属的试验工作,并已做出了显著成绩. 首先着手研究以瓷土管代替室内下水道金属管的是前城市建设总局辽宁省城市设计院.还在1954年,他们就进行了重点试用.此后,为了扩大使用面,他们又进一步改进并提高了产品质量,将陶土管改为陶瓷管,在一般民用建筑内全盘采用.其他如武汉市设计院、第一机械工业部、北京市设计院等单位,也曾经先后相继在某些工程中试用过陶土管或陶瓷管.考虑到室内外露部分的美观,去年三月,
In order to save metal materials on construction and reduce construction costs, many research, design and construction units have actively conducted experiments on the use of clay pipes and ceramic tubes instead of metals in waterway engineering and have made Significant results. The first step in the study of replacing ceramic pipes with indoor sewer pipes was the former Urban Construction Administration of Liaoning Provincial Urban Design Institute. In 1954, they conducted a key trial. Later, in order to expand the use of surface, they further improved. The quality of products has been improved, and the clay pipes have been changed to ceramic pipes, which have been adopted in general civil buildings. Others such as the Design Institute of Wuhan City, the First Machinery Industry Ministry, and the Beijing Design Institute have also successively worked on certain projects. Trial of earthenware tubes or ceramic tubes. Considering the appearance of indoor and outdoor exposed parts, last March,
