Description

Technical Field

[0001] The present invention relates to the technical field of rapid repair of a guyed tower wire foundation, and in particular to a quick-repair assembled spiral anchor composite pull plate foundation for a guyed tower and a construction method thereof. Background Art

[0002] Transmission line foundations are an effective measure to ensure that transmission and communication line towers can withstand catastrophic horizontal loads. Ensuring the safety of towers is crucial in power line repairs, especially under severe weather conditions such as wind and ice loads. Pull-pan foundations are primarily used to secure guy wires and resist the overturning or tensile forces of towers. Due to their fast construction speed, simple process, and strong adaptability, they have become a common foundation type in repair projects. They can meet the time requirements of emergency construction, adapt to a variety of terrain and soil environments, require less equipment, and facilitate rapid deployment. Furthermore, pull-pan foundations are relatively low-cost, making them suitable for temporary or small-scale repairs. They are also highly flexible and can be quickly disassembled or adjusted, making them suitable for temporary supports or transitional structures.

[0003] Currently, rectangular reinforced concrete truss foundations are widely used. They utilize the foundation's own weight to provide the tower with resistance to pullout and overturning. However, the large volume of reinforced concrete required for this type of foundation leads to high transportation costs, which can be a significant constraint, particularly in mountainous environments. Cast-in-place reinforced concrete truss foundations, on the other hand, involve tedious construction steps such as concrete pouring and excavation, resulting in a long construction period that makes it difficult to meet the time constraints of emergency repair operations.

[0004] Among other types of foundations, pile foundations (such as cast-in-place piles and excavated piles) have complex construction procedures and long construction cycles, and require large equipment and sufficient space. Their construction has high requirements for geological conditions, and complex geological conditions will increase the difficulty and risk of construction. In addition, the construction process of pile foundations is highly dependent on weather conditions (such as rainy season, frozen soil, etc.), which can easily lead to interruptions in the construction period, and the cost of materials, equipment and labor makes it less economical. The vibration, noise or settlement generated during the construction process may have an adverse impact on the surrounding environment, and coordination is more difficult. Prefabricated pile foundations are more commonly used in emergency repair projects. However, prefabricated pile foundations are still limited by construction conditions and transportation, and the construction site has high requirements for flatness and lifting equipment.

[0005] In summary, the existing foundation types generally have problems such as long construction period, poor adaptability, and poor economy in emergency repairs. There is an urgent need for a new type of foundation with a short construction period, strong adaptability, and the ability to ensure the stability of the tower in an emergency, so as to solve the shortcomings of the existing technology in emergency repair operations. Summary of the Invention
