坑道掘进中,常因水针损坏后一时供应不上而打干眼。我部二支队一分队军医孙可路同志和三连(师长的试验田)的鑽岩机手座谈,不用水针能不能打水眼?经过孙军医的启发,他们终于在无水针的情况下仍然打水眼,方法是:把盛水桶提高,距坑道口20-25公尺,水桶随时加水,以增加压力。输水管要保持通畅,由于鑽杆的旋转把水带入眼内,这样仍能保持打水眼。经过试验,在有水针的情况下,8小时出水量360公斤,而在无水针的情况下,8小时出水量720-1080公斤。由于用水量多,供水困难,因此此法仅是在水针折断后新水针尚未安装前的空隙时间应用。2.我部二支队修理组胡登云同志苦心鑽研,终于创造了火焊、电焊等接针法,大大改变了水针
Tunnel excavation, often due to short-term water needle damage and dry eye. Comrade Sun Kelu, Commander of the Second Detachment, and Commander Sun Kelu, both from the Second Detachment of the Ministry of China, discussed drilling with rock drillers without the needles of water needles. After Sun Junyi inspired them, Still frantically, the method is: raise the water tank, 20-25 meters away from the tunnel mouth, water bucket at any time to increase pressure. The hose should be left unobstructed to bring water into the eye as the drill pipe is rotated so that the water can still be kept. After testing, in the case of a water needle, 8 hours of water output of 360 kg, and in the case of needle water, 8 hours, 720-1080 kg of water. Due to the large amount of water, water supply difficulties, so this method is only after the water needle break new water needle before the installation of the gap time application. 2. Division II Detachment Repair Group Comrade Hu Dengyun painstaking study, and finally created a fire welding, welding and other access methods, greatly changed the water needle
