《建筑工人》1997年第3期刊登的《现场制作钎探工具》一文,对我们启发很大。经过我们实践应用,证明这种钎探工具比较适用。但我们在施工过程中,觉得按照文中所述利用穿钢筋的方法拔钎杆比较费力,见图1。利用杠杆原理,我们在施工中改变了原来的拔钎杆方法,见图2。一个人用φ50钢管(工地上的架杆)作撬杠,重复向下压,铁板就卡住钎杆,使钎杆逐渐上移,直至把钎杆拔出来。垫块可以选用工地上的砖、石
The article “Onsite Fabrication of Solder Exploration Tools” published in “Construction Workers” in the 3rd issue of 1997 has inspired us a lot. Through our practical application, it proved that this soldering tool is more applicable. However, during the construction process, we felt that it would be more laborious to use the method of wearing steel bars as described in the text. Using the principle of leverage, we changed the original method of pulling and boring rods during construction. See Figure 2. One person uses a φ50 steel pipe (a pole on the construction site) as a crowbar, and repeatedly presses down, and the iron plate catches the drill rod so that the drill rod gradually moves upward until the drill rod is pulled out. Pads can be selected on the site of the brick, stone
