为了解决高达十二层的深圳市“国际商业大厦”建筑中,垂直输送混凝土的难度,我们从1981年12月开始安装,由西德引进的两台PM大象牌混凝土输送泵车,在使用过程中,我们克服了高层架管困难,排除故障麻烦,对新机器生疏等一系列问题。从中总结出了如下几条经验,以供使用时参考。1.在垂直输送混凝土前,不必采用所谓海绵球操作规程; 2.开始输送混凝土时,需用半立方米、

The following experiences were summarized for reference during use. 1. It is not necessary to adopt the so-called sponge ball operation procedure before transporting the concrete vertically; 2. When the concrete starts to be transported, it takes half a cubic meter,
