Скачать или смотреть Hillside drilling operations – good tools and machinery make work more efficient

In the video, several construction workers work together to operate a large gasoline-powered ground drill, drilling a hole on a hillside. The auger bit rotates at high speed, cutting into and reeling out layers of soft soil, creating a deep, uniform circular hole. This type of equipment is commonly used for installing mountain protection piles, planting trees, or pre-buried foundations. Due to the undulating terrain and complex soil, multiple workers must coordinate to stabilize the drill's center of gravity. One person controls the throttle and torque, while others provide support to prevent the drill bit from getting stuck or twisting back, potentially injuring hands. The auger's operating principle combines rotary cutting with a threaded soil conveyor to quickly expel the soil produced by drilling, achieving efficient excavation. Compared to manual excavation, this mechanized method is over ten times more efficient and is particularly well-suited for mountain operations. However, safety is paramount. Before operation, the drill rod's tightness, throttle response, and torque direction should be checked to prevent accidents caused by twisting back and swinging the arm. This is a typical example of the "human-machine collaboration" wisdom of mountain construction, relying both on mechanical power and the workers' experience and tacit understanding.
