长春拖拉机厂在厂房内现有生产设备附近拆除一座10.5m~3旧混凝土基础。采用“无声破碎法”施工,收到较好的效果。用这种方法拆除混凝土,只需把混凝土按一定距离先钻出孔,在孔内装入“高效无声破碎剂”胶泥,然后定期浇水即可将混凝土破碎,操作方法简单,降低工人劳动强度,省时省力。“无声破碎法”原理主要是靠装入孔内的“高效无声破碎剂”胶 Changchun Tractor Factory dismantled a 10.5m~3 old concrete foundation near the existing production facilities in the plant. The use of “silent crushing” construction has received good results. Demolition of concrete by this method requires that the concrete be drilled at a certain distance first, and then the “high-efficiency silent breaker” cement is placed in the hole, and then the concrete can be crushed by regular watering. The operation method is simple and the labor intensity is reduced. save time and energy. The principle of “silent crushing method” is mainly based on the “high-efficiency silent breaker” built into the hole.
