Description

Technical Field

[0001] This invention relates to the field of pole manufacturing technology, and in particular to a double-layer reinforced equal-diameter prestressed concrete pole and its manufacturing process. Background Technology

[0002] In the actual production and manufacturing of utility poles, prestressed reinforced concrete poles refer to poles where, when bent under stress, one side of the pole's cross-section is under compression and the other side is under tension. Although the tensile force is mainly borne by the reinforcing steel, and the concrete elongates along with the steel, cracks may appear in the concrete due to tension. If the cracks are wide, water can seep in and cause the steel to corrode. The best way to prevent cracks is to pre-tension the steel before pouring the pole, so that the concrete bears pre-compressive stress before bearing the load. When the pole is under tension, the concrete in the tension zone will not crack due to the pre-compressive stress. These poles are made of concrete and reinforcing steel or wire. Utility poles are the bridge of electricity, allowing electricity to be transported to various places. At this time, a good double-layer reinforced equal-diameter prestressed concrete pole is particularly important.

[0003] For example, the invention with application number CN202110494128.8 provides a prestressed pole production line, including a steel reinforcement cage manufacturing area, a concrete preparation area, a concrete placement area, a formwork covering area, and a centrifugal curing area. The centrifugal curing area includes a centrifugal curing chamber and two hot water chambers, located on opposite sides of the centrifugal curing chamber. Both the centrifugal curing chamber and the two hot water chambers are located underground. A centrifuge and a driven roller assembly are installed inside the centrifugal curing chamber, with the centrifuge located on one side of the driven roller assembly. A ladder and a monitor are fixedly connected to the inner wall of the centrifugal curing chamber. This invention, by integrating the centrifugal and curing areas underground, reduces noise during the centrifugal operation of pole production and avoids injury from flying bolts. Furthermore, the poles can be cured directly after centrifugation, eliminating the need to hoist them to the curing chamber after centrifugation, reducing transfer steps, simplifying operation, and shortening production line time.

[0004] However, the existing double-layer reinforced equal-diameter prestressed concrete poles and their processes cannot achieve efficient prestressing tension, the adjustment of the reinforcement shaft diameter is inconvenient, affecting the pole processing quality. At the same time, they cannot achieve efficient auxiliary reinforcement, the welding of steel bars is not efficient and stable, and the accuracy is low. They also lack a support and measurement structure, which affects the prestressing tension of steel bars and the forming quality. Summary of the Invention

[0005] In view of this, the present invention provides a double-layer reinforced equal-diameter prestressed concrete pole and its process. The pole's main body can achieve efficient prestressing tensioning, effectively ensuring overall processing quality. The overall structure is simpler and more flexible in use. It can achieve rapid adjustment of the driven threaded connecting column by auxiliary rotation, thereby achieving auxiliary adjustment of prestressing and ensuring the overall prestressing amount.
