喷射混凝土时采取降尘措施是保证工人身体健康和降低材料消耗的一项重要的技术问题。为此,我们在河南省第四建井工程处的指定工作面进行潮喷试验,并作了一些参数的测定,以期了解喷射机对潮喷的适应性、潮料湿度、水灰比的变化状况及降尘作用等。
It is an important technical issue to ensure the health of workers and to reduce the material consumption by adopting dust control measures when spraying concrete. For this reason, we carried out the tidal injection test on the designated working face of the No.4 Well Construction Agency of Henan Province and made some measurements to understand the adaptability of the jetting machine to the tidal jet, the moisture of the tide material and the change of the water cement ratio Status and dust effect.
