刻槽方法的改进(一)两边拉槽刻取法的缺点这种方法是在刻槽取样时最常采用的方法.就是在槽位两边,分别刻出两条近似全槽深度的窄沟,宽约2-3公分,(图1a、6),然后从槽的中心,向两边乱凿(图1B),最后使中央部份全部脱落(图1г).由于窄沟开凿困难,所以还得用扁凿将凹凸不平之处返修一次.根据我们长期工作的经验,认为这种工作方法存在如下缺点,以至严重的影响刻槽工作的效率及质量.1.拉槽用的时间很多,影响实际工作的速度.
Improvements in the notch method (a) The shortcomings of the two-sided notch sculpting method This method is the most commonly used method for notch sampling. It is on the two sides of the groove, respectively, carved out two narrow grooves that are approximately the depth of the full groove, wide About 2-3 cm, (Fig. 1a, 6), then from the center of the slot, to both sides (Fig. 1B), and finally make all the central part fall off (Fig. 1 г). Due to the narrow trench ditching difficulty, it has to be used The flat chisel will be reworked once and again. According to our long-term work experience, we believe that this working method has the following shortcomings, as well as the serious impact on the efficiency and quality of groove work. 1. Slotting time is many, affect the actual work speed.
