[0002] At present, when most construction sites are constructing long spiral bored and grouted piles (also known as the post-insertion steel cage process), the tapered mouth of the steel cage is usually formed by single-sided welding of the main reinforcement. When the steel cage is implanted in the concrete and the vibrating hammer is started, the welding part of the tapered mouth of the steel cage is easily detached, causing the steel cage inlet pipe to pass through the tapered mouth, and then causing the steel cage to fail to reach the design depth. In addition, in the prior art, no steel casing protection device is set at the top of the pile, and the verticality of the steel cage and the quality of pile positioning are difficult to control. Moreover, this traditional method requires a lot of manpower under tight construction schedules, which leads to increased costs, correspondingly increased risks, and difficult to guarantee construction quality.
