Description

Technical Field

[0001] The utility model belongs to the technical field of embedded part reinforcement, and in particular relates to an embedded part reinforcement device for an iron tower pile foundation. Background Art

[0002] The embedded parts of overhead line tower foundation rely on traditional reinforcement methods, which use steel and foundation steel cage welding. This method is difficult to construct; it requires manual work in the steel cage, which has high safety risks. Concrete vibration and embedded parts shift, resulting in poor installation precision control. In addition, the reinforcement with steel bars or angle steel is basically a one-time reinforcement. The reinforcement and removal takes a long time. There is also the problem of increased costs due to the non-reusability of reinforcement materials.

[0003] The project is located in the dry and hot canyon area of ​​Beipanjiang in southern Guizhou. The mountains are undulating. Due to the terrain conditions, the 35kV double-circuit overhead collector line from the photovoltaic field to the booster station needs to cross the undulating canyon mountains. The line has a large height difference at the hanging point, the maximum of which is 248m, and the span is large, the maximum span is 900m. The aperture of the tower foundation is designed to be large, the embedded parts have large structural dimensions, and the on-site construction material transportation mainly relies on mule transportation. The connection between the tower and the foundation is connected by anchor bolts. The foundation type is mainly "WJ" type, and the anchor bolts are straight column type. The maximum weight of the anchor bolts of a single leg foundation of the tower is 136kg. The anchor bolts are located at the center of the top surface of the foundation. Reinforcement relies on traditional reinforcement methods. Steel welding reinforcement is a one-time consumption, which is more material-consuming, and reinforcement and removal take a long time and labor-intensive, so the cost is high, the construction is difficult, the safety risk is high, and the installation accuracy control is poor. Therefore, it is urgent to study a safe, convenient, reliable, economical, labor-saving and reusable embedded parts reinforcement device.

[0004] The patent document with the publication number CN216892502U discloses a tower foundation embedded parts installation and positioning device, including a positioning module, a first connecting member and a second connecting member. The number of the positioning modules is equal to the number of embedded parts and the positions correspond one to one. The middle of the positioning module is hollowed out to reduce weight. The positioning module is also provided with a positioning hole for corresponding insertion of bolts on the embedded parts. The positioning module is sleeved on the embedded parts through the positioning hole. A first connecting member is provided between any two adjacent positioning modules, and a second connecting member is provided between at least two non-adjacent positioning modules. Two second connecting members with a cross relationship are reinforced at their cross positions, and each connecting member is removable. However, the device combines multiple tower foundations to simultaneously position embedded parts, and operations such as positioning, handling and stabilizing devices require more manpower. If multiple foundations are simultaneously poured with concrete, the concrete will be affected by vibrations in multiple directions during vibration, which is not convenient for maintaining the positioning of embedded parts.
