Problems solved by technology
[0006] (1) The built overhead power transmission tower is located within the scope of the backfill earthwork. The tower foundation and some tower materials are buried in the earthwork, which cannot effectively protect the tower materials from corrosion and cannot make the tower body and foundation bear reasonable force.
[0007] (2) The self-heavyness of large-volume concrete, the bearing capacity of the foundation cannot meet the requirements, causing uneven settlement of the foundation, tilting of the tower, and cannot be used normally
However, the built towers are located in the flat area, which restricts urban development and the land cannot be used effectively

Embodiment
[0047] The novel iron tower foundation reinforcement and protection method provided by the embodiment of the present invention includes:
[0048] First build four new foundations, then chisel the top surface of the original iron tower foundation, bind the wall reinforcement, support the wall template, pour the wall concrete, the vibrator cannot directly touch the tower material, and the strength of the concrete can reach more than 70%. Remove the formwork; the construction should choose the concrete mix ratio reasonably, choose cement with low heat of hydration, add appropriate fly ash and admixture, control the amount of cement, and make maintenance and temperature measurement. The difference between the internal temperature of the concrete and the surface temperature, and the difference between the external surface of the concrete and the ambient temperature should not exceed 25°. The main reinforcement of the pile in the contact part of the pile and the ring beam is anchore...

The invention belongs to the technical field of iron tower foundation reinforcement and protection, and discloses a novel method for iron tower foundation reinforcement and protection. A reinforced concrete protective wall is used for wrapping an iron tower body, a steel reinforced concrete shear wall barrel composite structure with strip steel diagonal bracing is formed with an iron tower material together, the external load is effectively resisted, the tower material is located in the middle of the wall, the tower body partition surface is wrapped with a reinforced concrete partition surfaceprotective plate, a plurality of permeable holes are formed in the middle of the plate, and four new pile foundations (or an excavation foundation, a stepped foundation) are constructed at the bottomof the tower to bear the loads of the tower body and the reinforced concrete protective wall jointly with an original tower foundation; and ground planting soil on the lower part of the tower is cleared, gravelly soil is laid, bag soil is piled around the tower body, and muck is evenly backfilled and compacted. According to the novel method for iron tower foundation reinforcement and protection,permanent protection is formed on the tower material, stress is reasonable, and the use function of an iron tower is not affected.
Description
technical field [0001] The invention belongs to the technical field of iron tower foundation reinforcement and protection, and in particular relates to a novel iron tower foundation reinforcement and protection method. Background technique [0002] At present, the closest existing technology: the tower body is brushed with anti-rust paint to backfill the soil body, and the tower body is buried with plain concrete. [0003] The tower body is buried in the backfill soil, and the tower body is painted with anti-rust paint. The tower material is eroded by groundwater for a long time. The service life of the anti-rust paint is limited, and it cannot form permanent protection for the tower material. [0004] The plain concrete body buries the tower body, forming a permanent protection for the tower material, but the large-volume concrete is heavy, which is easy to cause foundation settlement, tower tilting, and accidents. [0005] In summary, the problems in the prior art are: ...
