[0002] In pile foundation projects, the main purpose of fixing multiple grouting pipes on the steel cage is to improve the bearing capacity of the pile foundation, prevent the pile foundation from settling, and increase the service life of the pile foundation. The total length of the grouting pipe is the total length of the steel cage plus the height of the empty pile section, and then plus the height above the ground. The empty pile section refers to the part of the pile body where the pile top elevation is below the actual ground elevation, there is a certain distance from the ground but it is not filled with soil. During construction, in order to meet the design requirements, the grouting pipes set in the empty pile section need to be reinforced. At present, the grouting pipes in the empty pile section of pile foundation projects are generally welded to the guide steel bars, and reinforcing stirrups are set at intervals. On the one hand, such treatment will lead to a large amount of steel bar waste, and this section of steel bar cannot be reused. On the other hand, the welding of the grouting pipe and the steel bar can easily cause the grouting pipe to leak, affecting the grouting quality. In order to effectively fix the grouting pipe of the empty pile section, this application document provides a grouting pipe stabilization bracket. Utility Model Content
