几年来,坑道掘进中使用的炮泥,全是手工操作,不仅效率低,而且质量很差,每到冬天泥球工双手冻僵冻裂。为了提高炮泥质量和制作效率,改善工人劳动条件,我们用废钻探管材试制成功了简易螺杆炮泥压缩机(如图),在生产上取得了良好的效果。一、炮泥机的制作方法
In recent years, the shotcrete used in tunnel excavation is all manual operation, not only inefficient, but also poor quality, every winter mud ball workers frozen frozen. In order to improve the quality and production efficiency stemming and improve the working conditions of workers, we use the waste drilling pipe trial production of a simple screw stem compactor compressor (pictured), in the production has achieved good results. First, the method of making mudflats
