Air stream agitating and ebullient spraying technology and equipments of this invention is chiefly used in tunneling and mining lanes for spraying anchorage and supporting layers on the working surfaces. Different air stream pressure principle is adopted for concrete suck-in to the final spraying to complete the production line. Moreover, the relevant equipments with said process such as mixer, ebullient spraying cart, centrifugal mixer etc. to substitude the existing mechanical grouting equipments. As compared with the existing process, said invention possesses advantages of no contamination, simple construction, low cost, long lifetime and less material consumption on site. |
