钻进法是掘进天井的一种机械化程度较高的施工方法,国外已广泛使用。我国从七十年代以来,相继研制成功了TYZ型和AT型天井钻机,在天井钻进中取得了显著的效果。本文着重对上述类型天井钻机在天井钻进中的成本、工效、月成井速度等方面进行全面的分析,指出我国在相应条件下推广钻进法具有普遍的现实意义。
Drilling method is a kind of mechanized tunneling construction method of a higher degree of pavement, has been widely used abroad. Since the 1970s, China has succeeded in developing the TYZ-type and AT-type well drilling rigs in succession, and achieved remarkable results in the drilling of the patio. This article focuses on the cost, work efficiency and the rate of monthly well completion of the above-mentioned type of well boring machine in a comprehensive analysis. It points out that it is of universal and practical significance for China to promote the drilling method under the corresponding conditions.
