摘要: 热水钻是利用锅炉生产的热水,通过绝热性能较好的橡胶布夹层管,经变径增压喷头将承压热水喷向冰层,利用热动能将冰融化钻进,从而完成在冰川上钻孔。我们参考了国外有关热水钻的资料[1-2],于1982年自行设计了冰川-Ⅰ型热水钻,经现场试验在冰川上钻深达到109.91米,最高钻速27.27米/小时,计算最大钻深可达130米。

Abstract: In this paper, construction, design and technical data of Type Glacier-I Hot-Water ice auger were introduced. This apparatus was successfully developed, the first of its kind in our country, and its experimental results at Tian Shan Glaciological Station were also given.It showed that the drilling speed is 27.27 m/h, reaching a depth of 109.91 m with a continual drilling on the Glacier No.1 in Tian Shan Glaciological Station (altitute 3,850 m).Experimental result shows that the device is reasonably designed and characterized by light-weight and portable, simple structure, easy operation and high efficiency. It is favourable for glacial investigation.
