经过改进设计的混凝土喷射机(外形见封三),经工业性试验考核后,于1974年11月通过了部级鉴定,并开始用于生产实践。该机适用于国防、矿山、铁路、水电、建筑等地上地下工程、巷道、隧道、隧洞混凝土的喷射、浇灌及修补抢修支护。亦可用于高炉、炼钢平炉、转炉及各种热工炉的防火层裂缝、洞眼的喷补工作。施工工艺简单,效率高,速度快,劳动强度低,省工省料,便于实现机械化作业。
After the improved design of the concrete sprayer (see the outline of the cover three), after the industrial test assessment, in November 1974 passed the ministerial appraisal, and began to use for production practice. This machine is suitable for spraying, irrigating, repairing, repairing and repairing of underground and underground projects such as defense, mines, railways, hydropower, and construction, tunnels, tunnels, and tunnels. Can also be used for blast furnace, steel furnace, converter and a variety of thermal furnace fire protection cracks, holes in the gunning work. The construction process is simple, high-efficiency, high-speed, low labor intensity, labor-saving materials, and convenient for mechanized operations.
