以钢模代替木模已经在铁路隧道建筑混凝土工程中,取得了十分明显的经济效益。它不仅节约了大量我国所缺乏的木料,而且由于钢模的耐久性,倒用次数比木模多得多,安装和维修方便,从而也节省了模板费用。同时,使用了钢模板,混凝土表面更为光滑美观。在单、双线隧道工程中使用半机械化钢模板台车,在经济效益、施工速度和工程
To replace the wood mold steel has been in the railway tunnel construction of concrete works, made a very significant economic benefits. Not only does it save a great deal of lumber lacking in our country, but also because of the durability of the steel die, the number of back-in times is much more than that of the wood die, and the installation and maintenance are convenient, thus saving the cost of the die. At the same time, the use of steel template, the concrete surface is more smooth and beautiful. In the single and double tunnel project using semi-mechanized steel template trolley, the economic benefits, construction speed and engineering
