1977年,我公司承担河南炼油厂基本建设任务。为了适应工程需要,本着既要少花钱,又要尽快建成投产的原则,我们选择了一块沟边场地作为混凝土预制场,根据现场条件,利用自然地形,设计了一座混凝土搅拌站,于1978年7月投入生产。四年多的使用表明,其性能稳定,达到了规定要求。 In 1977, our company assumed the basic construction tasks for the refinery in Henan. In order to adapt to the needs of the project, in accordance with the principle of not only spending less money, but also completing and commissioning it as soon as possible, we chose a ditch-side site as a concrete prefabricated site. According to the site conditions, a concrete mixing plant was designed using natural terrain, in 1978. In July of this year, it was put into production. The use of more than four years shows that its performance is stable and meets regulatory requirements.
