Скачать или смотреть The precise power of pouring one bucket at a time: pouring pile foundations with a dump truck

In the video, a worker manually pushes a bucket truck to pour concrete into the pile foundation hole. After pushing the bucket truck to the hole opening, he stabilizes the truck and slowly lifts the bucket, allowing the concrete to pour smoothly into the hole. This seemingly ordinary operation is actually crucial to controlling concrete quality. Because this construction method does not require pumping pressure, the concrete must possess excellent workability and fluidity, allowing it to flow smoothly down and fill the hole bottom, while not being too diluted to cause segregation or insufficient strength. Therefore, the water-cement ratio is typically controlled during mixing to maintain the viscosity of the slurry enveloping the aggregate and achieve an appropriate slump. During pouring, the worker controls the speed, allowing the concrete to fall in layers and spread naturally, avoiding damage to the reinforcement cage or the formation of voids due to a sudden, excessive impact. Although this method relies on manual labor, it allows for precise control of the rhythm of each bucket's entry into the hole. It demonstrates the integration of on-site construction experience and material properties—even without mechanical equipment, scientific proportioning and operation techniques can still ensure structural strength and pile quality.
