为了适应我国建筑施工、安装、市政建设和混凝土工程质量检验工作的需要。城乡建设环境保护部机械管理局下达天津建筑仪器厂试制HZQ-100型混凝土钻孔取样机新产品任务。经过调研、设计、试制和工业考核,于1986年7月19日在天津正式通过部级鉴定,该机主要技术性能参数达到国外同类产品先进水平。 HZQ-100型混凝土钻孔取样机(见附图)是一种小型轻便、高效率、多功能建筑装修 In order to meet the needs of China’s construction, installation, municipal construction and concrete engineering quality inspection work. The Ministry of Urban and Rural Construction and Environmental Protection Machinery Administration Bureau issued Tianjin Construction Instrument Factory to trial-produce new product of HZQ-100 concrete borehole sampling machine. After investigation, design, trial production and industrial assessment, it was officially approved at the ministerial level in Tianjin on July 19, 1986. The main technical performance parameters of the aircraft reached the advanced level of similar foreign products. HZQ-100 concrete borehole sampling machine (see attached) is a small, light, high-efficiency, multi-functional building decoration
