| Abstract: | A new type of the reverse circulstion percussion drilling rig Model CZF-1200 is introduced, which is reliable in operation,easy to operate and maintain,and has gial fatigue resistance and high efficiency. It is suitable for construction of anti-seepage diaphragm wall in hydro project and can meet various kinds of geologic strain. The corollary facilities such as reverse circulation sand and gravel pump, slurry purifying equipment, telescopic bit, san and gravel discharge pipe, and hydraulic double inverted arch bit for wall junction are reasonably designed. |
