Description

Technical Field

[0001] The utility model relates to the technical field of low-headroom mixing piles, in particular to a full-automatic connecting rod low-headroom mixing pile. Background Art

[0002] A mixing pile is a columnar reinforcement body with a certain strength, integrity and water stability formed by cement slurry and other materials and soil after the soil is treated by deep mixing method. The vertical height of the mixing pile machine body is generally high and the drill rod is long. When the construction site is affected by the environment with limited vertical space such as high-voltage lines and low-clearance bridges, the traditional mixing pile machine cannot be used due to insufficient construction clearance. The upper and lower ends of the traditional drill rod are provided with matching external threads and internal threaded holes. When the two drill rods are connected, one of the drill rods is rotated to connect them together with threads. This method not only has low connection efficiency, but also has high labor intensity during the drill rod connection process. In addition, the threaded drill rod is easily damaged during rotation, causing the drill rod connection to loosen, affecting the drilling operation, and the existing drill rod is not easy to move during the connection process, which reduces the applicability of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
