氧气站的充瓶车间,由于氧气瓶长期在地面上滚压、磨擦、撞击.对地坪有较高的强度和耐磨的要求。上海彭浦机器厂氧气站1961年建成投产,当时的车间地坪基层为110号,厚150m m混凝土,面层为300号,厚30mm的细石混凝土。使用前经过测定面层强度完全达到设计要求。但是,投产后三个月,地面因受氧气瓶的滚压、磨擦、撞击,面层 Oxygen filling station of the station, due to oxygen cylinder rolling, friction, impact on the ground for a long time. The floor has a higher strength and wear resistance requirements. The oxygen station of Shanghai Pengpu Machinery Plant was completed and put into production in 1961. At that time, the floor of the workshop floor was 110#, 150m thick concrete, 300# surface layer, and 30mm thick fine stone concrete. After use, the strength of the surface layer was completely measured to meet the design requirements. However, three months after it was put into production, the ground was subjected to rolling, friction and impact by oxygen cylinders.
