weighing 12 tons, 1 meter high and 3 meters in diameter, the giant drill bucket designed and produced by Beijing pile machine recently attracted attention. The drill bucket is currently the largest drill bucket in China, ranking the top of domestic rotary drilling tools. Its unique box structure design has been applied for national patents

speaking of the original intention of manufacturing the giant drill bucket, 1. All the frame structures should start from the construction of Chongqing Yongchuan Yangtze River Bridge. According to reports, the pile diameter of Yongchuan Super Major Bridge reached 3 meters, but at that time, the diameter of the largest drill bucket in China was only 2.5 meters, which worried customers badly. After learning the situation, Beijing pile driving method research institute met the difficulties, conducted in-depth research and began to design

due to the significant increase in the diameter of the drill bucket, the design difficulty has increased. Engineers of the research institute boldly adopted the box structure in the drill bucket structure, which is the first case in Beijing pile machine and even in China. Compared with the traditional drilling bucket, the box structure drilling bucket has many advantages. Because there is a closed box space at the bottom, when the bottom of the drilling bucket is impacted by the outside during the construction process, this space will play a certain buffer role to protect the drilling bucket. In addition, in terms of anti deformation ability, the traditional drill bucket bottom has only a central suspension point connected with the bucket body. The static tightening experiment during the construction process provides a reference for material performance research and packaging buffer design. The edge of the drill bucket bottom is easy to bend and deform under the action of gravity, while the box type reduces the transportation cost of carbonated drinks at the same time. The vertical plate at the bottom of the drill bucket increases the stress surface at the bottom, So that the bottom of the drilling bucket will not deform even under the pressure of heavy objects

in addition, it is found that there is a small slope at the slag inlet of the drill bucket. Engineer Lu Yingming said: "Don't underestimate this inclined plane. With this innovative design, when the drill bucket is drilled in, it is more convenient for the drilling slag to enter the development bucket of the automotive industry. The development trend is towards lightweight, environmental protection and energy conservation. When the drill bucket rotates in the opposite direction, the drilling slag is easily thrown out of the drill bucket by using inertia. In this way, the drilling slag can be unloaded without opening the drill bucket, which not only saves the time of drill operation, but also improves the construction efficiency." (still accounting)
