为实现金刚石钻孔的架桥，根据其特点（如孔壁间隙小），作如图所示的架桥，其结构简单，容易制作，操作方便，并且可靠性良好。其操作方法及注意事项如下1．按图示组装木塞，然后将木塞下到需“架桥”孔深部位；2．慢转钻杆，使其由反扣处脱开，使卡料由储存室内流出，落到木塞台肩处；3．轻轻提动钻杆，使储存室和木塞之间的被敷线拉紧，直至拉断为止； To achieve the bridge of diamond drilling, according to its characteristics (such as small hole wall space), as shown in the bridge, its simple structure, easy to manufacture, easy to operate, and good reliability. The operating methods and precautions are as follows 1. Assemble the cork according to the picture, and then place the cork down to the deep part of the hole to be bridged. 2. Slowly turn the drill pipe, so that from the anti-buckle off, the card material from the storage room outflow, fell to the cork shoulder; 3. Gently raise the drill pipe, so that the storage room and the cork was coated wire tensioning until pulled off;
