《建筑工人》杂志真好,我从中学习了不少的知识。就拿清理搅拌机来说吧,上面的混凝土灰渣是很不容易弄掉的。后来我看到杂志上介绍事先刷上一遍油,在阳光下晒2天后,就可去掉混凝土灰渣。经过实践,确实解决了难题。希望《建筑工人》杂志越办越好,让建筑工人多多受益。 The “Construction Worker” magazine is really good. I learned a lot of knowledge from it. Take the clean-up mixer. The concrete ash above is not easy to get rid of. Later, I saw the magazine introducing oil in advance, and after drying in the sun for 2 days, concrete ash can be removed. After practice, it has indeed solved the problem. It is hoped that “Construction Worker” magazine will be better and better, so that construction workers will benefit a lot.
