Natural disasters such as earthquakes, floods, and heavy rains often bring devastating impacts to human society, leaving behind damaged infrastructure, blocked transportation routes, and hazardous living environments. In the critical post-disaster phase, efficient and scientific disaster relief work is essential to safeguarding people’s lives and property, restoring social order, and laying the foundation for long-term reconstruction. Among the diverse disaster relief tasks, landslide clearing, river dredging, and post-disaster rubble demolition and site repair are three core pillars. They target the most urgent and destructive consequences of disasters, forming a systematic chain of emergency disposal that ensures the smooth progress of subsequent rescue and reconstruction efforts.
