从洞庙河年走行三百万公里蒸汽机車阶段型机务段的調查工作中,发現以往設計由于缺乏調查研究,特別是对洗修庫及技术检查庫的作业特点和性质了解不深入,因此对某些設計問題不能提出正确的設計方案,以致造成脫离实际甚至影响了正常使用。以下是根据調查情况提出几点体会,供今后設計参考。但由于这次調查存在一定的局限性并且深入不够,片面和錯誤之处在所难免,欢迎同志們指正。一、屋盖构件的防腐蝕問題 以往設計洗修及技术检查庫的鋼筋混凝土屋盖构件时,也考虑到庫內湿度大烟气多的特点,对构件內鋼筋的混凝土保护层要求比正常使用情况下增加一厘米,以防止鋼筋遭到绣蝕,有时甚至要求在构件表面涂耐酸
In the investigation of the three-million-kilometer steam locomotive-type locomotive depot from Dongmiaohe River, it was found that in the past, due to the lack of investigation and study, especially the understanding of the operating characteristics and nature of the washing and technical inspection depot, For some design problems can not be put forward the correct design, resulting from the actual or even affect the normal use. The following is based on the survey made a few experiences for future reference design. However, due to the limitations and in-depth limitations of the survey, unilateralism and mistakes are inevitable. First, the corrosion protection of the roof member In the past, when designing the reinforced concrete roof member of the washing and technical inspection warehouse, it also took into account that the humidity in the storage room was large and the flue gas was large. The requirements of the concrete protective layer of the reinforced concrete member were higher than those of normal use In the case of one centimeter increase, in order to prevent the embroideries of reinforced steel, and sometimes even require acid
