二十多年来,北京市建筑业的建筑施工机械装备发展速度是比较快的。当前存在的主要问题,一是数量不多,二是型号复杂,三是产品陈旧,性能较差,四是不配套,五是完好率不高,与国外工业先进国家的相比,存在着较大差距。实践表明,基本建设的发展对建筑施工机械设备提出了新的要求,而建筑机械设备的发展又反过来推动了建筑技术的进步和建筑施工能力的提高。 For more than two decades, the development speed of construction machinery and equipment in the construction industry in Beijing has been relatively fast. The main problems that currently exist are: the quantity is not large; the second is the complicated model; the third is the obsolete product; the poorer performance; the fourth is unmatched; and the fifth is the insufficiency rate, and compared with foreign advanced industrial countries, there is a comparative Big gap. Practice shows that the development of basic construction puts forward new requirements for construction machinery and equipment, and the development of construction machinery and equipment has in turn promoted the progress of building technology and the improvement of building construction capabilities.
