摘要
文章结合工程实例从箅式平台安装就位、定位导向器安装、组合钻塔的加工与安装、护孔管的安装等方面。介绍了在陡倾角岩塞基岩坡面上进行水上精准斜孔的钻进施工方法。
In combination with practice, in the paper, the boring methods of the precisely inclined holes with steep dip angle in slope of rock plug bedrock on water are introduced in terms of the installation and positioning of tbe grate platform, installation of positioning guide, processing and installation of the combined boring tower, and the installation of the hole protection tube, etc.
